Washing one's hands, a form of hygiene, is the most effective way to prevent the spread of infectious diseases.
Hygiene is a set of practices performed to preserve health. According to the World Health Organization (WHO), "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases."[2]Personal hygiene refers to maintaining the body's cleanliness. Hygiene activities can be grouped into the following: home and everyday hygiene, personal hygiene, medical hygiene, sleep hygiene, and food hygiene. Home and every day hygiene includes hand washing, respiratory hygiene, food hygiene at home, hygiene in the kitchen, hygiene in the bathroom, laundry hygiene, and medical hygiene at home. And also environmental hygiene in the society to prevent all kinds of bacterias from penetrating into our homes.
Many people equate hygiene with "cleanliness", but hygiene is a broad term. It includes such personal habit choices as how frequently to take a shower or bath, wash hands, trim fingernails, and wash clothes. It also includes attention to keeping surfaces in the home and workplace clean, including bathroom facilities. Adherence to regular hygiene practices is often regarded as a socially responsible and respectable behavior, while neglecting proper hygiene can be perceived as unclean or unsanitary, and may be considered socially unacceptable or disrespectful, while also posing a risk to public health.
Definition and overview
Hygiene is a practice[3] related to lifestyle, cleanliness, health, and medicine. In medicine and everyday life, hygiene practices are preventive measures that reduce the incidence and spread of germs leading to disease.[4]
Hygiene practices vary from one culture to another.[5]
In the manufacturing of food,[6] pharmaceuticals,[7] cosmetics,[8] and other products, good hygiene is a critical component of quality assurance.
The terms cleanliness and hygiene are often used interchangeably, which can cause confusion. In general, hygiene refers to practices that prevent spread of disease-causing organisms. Cleaning processes (e.g., handwashing[1]) remove infectious microbes as well as dirt and soil, and are thus often the means to achieve hygiene.
Home hygiene pertains to the hygiene practices that prevent or minimize the spread of disease at home and other everyday settings such as social settings, public transport, the workplace, public places, and more. Hygiene in a variety of settings plays an important role in preventing the spread of infectious diseases.[9] It includes procedures like hand hygiene, respiratory hygiene, food and water hygiene, general home hygiene (hygiene of environmental sites and surfaces), care of domestic animals, and home health care (the care of those who are at greater risk of infection).[10]
At present, these components of hygiene tend to be regarded as separate issues, although based on the same underlying microbiological principles. Preventing the spread of diseases means breaking the chain of infection transmission so that infection cannot spread. "Targeted hygiene" is based on identifying the routes of pathogen spread in the home and introducing hygiene practices at critical times to break the chain of infection.[11] It uses a risk-based approach based on Hazard Analysis Critical Control Point (HACCP).[12]
The main sources of infection in the home are people (who are carriers or are infected), foods (particularly raw foods), water, pets, and domestic animals.[13] Sites that accumulate stagnant water – such as sinks, toilets, waste pipes, cleaning tools, and face cloths – readily support microbial growth and can become secondary reservoirs of infection, though species are mostly those that threaten "at risk" groups. Pathogens (such as potentially infectious bacteria and viruses – colloquially called "germs") are constantly shed via mucous membranes, feces, vomit, skin scales, and other means. When circumstances combine, people are exposed, either directly or via food or water, and can develop an infection.[14]
The main "highways" for the spread of pathogens in the home are the hands, hand and food contact surfaces, and cleaning cloths and utensils (e.g. fecal–oral route of transmission). Pathogens can also be spread via clothing and household linens, such as towels. Utilities such as toilets and wash basins were invented to deal safely with human waste but still have risks associated with them. Safe disposal of human waste is a fundamental need; poor sanitation is a primary cause of diarrhea disease in low-income communities. Respiratory viruses and fungal spores spread via the air.[15]
Good home hygiene means engaging in hygiene practices at critical points to break the chain of infection.[11][13] Because the "infectious dose" for some pathogens can be very small (10–100 viable units or even less for some viruses), and infection can result from direct transfer of pathogens from surfaces via hands or food to the mouth, nasal mucous, or the eye, "hygienic cleaning" procedures should be adopted to eliminate pathogens from critical surfaces.[16]
Hand washing (or handwashing), also known as hand hygiene, is the act of cleaning one's hands with soap or handwash and water to remove viruses/bacteria/microorganisms, dirt, grease, and other harmful or unwanted substances stuck to the hands. Drying of the washed hands is part of the process as wet and moist hands are more easily recontaminated.[17][18] If soap and water are unavailable, hand sanitizer that is at least 60% (v/v) alcohol in water can be used as long as hands are not visibly excessively dirty or greasy.[19][20] Hand hygiene is central to preventing the spread of infectious diseases in home and everyday life settings.[21]
The World Health Organization (WHO) recommends washing hands for at least 20 seconds before and after certain activities.[22][23] These include the five critical times during the day where washing hands with soap is important to reduce fecal-oral transmission of disease: after using the toilet (for urination, defecation, menstrual hygiene), after cleaning a child's bottom (changing diapers), before feeding a child, before eating and before/after preparing food or handling raw meat, fish, or poultry.[24]

Respiratory hygiene
Correct respiratory and hand hygiene when coughing and sneezing reduces the spread of pathogens particularly during the cold and flu season:[9]
Carry tissues and use them to catch coughs and sneezes, or sneeze into your elbow.
Dispose of tissues as soon as possible.
Hygiene in the kitchen, bathroom and toilet
Hygiene in the kitchenHygiene in the bathroom
Routine cleaning of hands, food, sites, and surfaces (such as toilet seats and flush handles, door and tap handles, work surfaces, and bath and basin surfaces) in the kitchen, bathroom, and toilet rooms reduces the spread of pathogens.[25] The infection risk from flush toilets is not high, provided they are properly maintained, although some splashing and aerosol formation can occur during flushing, particularly when someone has diarrhea. Pathogens can survive in the scum or scale left behind on baths, showers, and washbasins after washing and bathing.[26][27][28]
Hygiene in the toilet
Thorough cleaning is important to prevent the spread of fungal infections. Molds can live on wall and floor tiles and on shower curtains. Mold can be responsible for infections, cause allergic reactions, deteriorate/damage surfaces, and cause unpleasant odors. Primary sites of fungal growth are inanimate surfaces, including carpets and soft furnishings.[29][30] Airborne fungi are usually associated with damp conditions, poor ventilation, or closed air systems.[31]
Mechanical removal (i.e., cleaning) using a soap or detergent. To be effective as a hygiene measure, this process must be followed by thorough rinsing under running water to remove pathogens from the surface.

In some cases, combined pathogen removal with kill is used, e.g., laundering of clothing and household linens such as towels and bed linen.
House deep-cleaning an intensive cleaning process targeting often-neglected areas, enhancing aesthetics, and improving health by reducing allergens and bacteria. It typically includes tasks like detailed dusting, appliance cleaning, and carpet shampooing, recommended biannually to maintain a home's hygiene and air quality.
Laundry hygiene
Laundry hygiene involves practices that prevent disease and its spread via soiled clothing and household linens such as towels.[34] Items most likely to be contaminated with pathogens are those that come into direct contact with the body, e.g., underwear, personal towels, facecloths, nappies. Cloths or other fabric items used during food preparation, or for cleaning the toilet or cleaning up material such as feces or vomit are a particular risk.[13]
Microbiological and epidemiological data indicates that clothing and household linens are a risk factor for infection transmission in home and everyday life settings as well as institutional settings. The lack of quantitative data linking contaminated clothing to infection in the domestic setting makes it difficult to assess the extent of this risk.[34][13][35] This also indicates that risks from clothing and household linens are somewhat less than those associated with hands, hand contact and food contact surfaces, and cleaning cloths, but even so these risks need to be managed through effective laundering practices. In the home, this should be carried out as part of a multibarrier approach to hygiene which includes hand, food, respiratory, and other hygiene practices.[34][13][35]
Infectious disease risks from contaminated clothing can increase significantly under certain conditions - for example, in healthcare situations in hospitals, care homes, and the domestic setting where someone has diarrhoea, vomiting, or a skin or wound infection. The risk increases in circumstances where someone has reduced immunity to infection.
Hygiene measures, including laundry hygiene, are an important part of reducing spread of antibiotic-resistant strains of infectious organisms.[36][37][38] In the community, otherwise-healthy people can become persistent skin carriers of MRSA, or faecal carriers of enterobacteria strains which can carry multi-antibiotic resistance factors (e.g. NDM-1 or ESBL-producing strains). The risks are not apparent until, for example, they are admitted to hospital, when they can become "self infected" with their own resistant organisms following a surgical procedure. As persistent nasal, skin, or bowel carriage in the healthy population spreads "silently" across the world, the risks from resistant strains in both hospitals and the community increases.[37] In particular the data indicates that clothing and household linens are a risk factor for spread of S. aureus (including MRSA and PVL-producing MRSA strains), and that effectiveness of laundry processes may be an important factor in defining the rate of community spread of these strains.[34][39] Experience in the United States suggests that these strains are transmissible within families and in community settings such as prisons, schools, and sport teams. Skin-to-skin contact (including unabraded skin) and indirect contact with contaminated objects such as towels, sheets, and sports equipment seem to represent the mode of transmission.[34]
During laundering, temperature and detergent work to reduce microbial contamination levels on fabrics. Soil and microbes from fabrics are severed and suspended in the wash water. These are then "washed away" during the rinse and spin cycles. In addition to physical removal, micro-organisms can be killed by thermal inactivation which increases as the temperature is increased. Chemical inactivation of microbes by the surfactants and activated oxygen-based bleach used in detergents contributes to the hygiene effectiveness of laundering. Adding hypochlorite bleach in the washing process achieves inactivation of microbes. A number of other factors can contribute including drying and ironing.
Drying laundry on a line in direct sunlight is known to reduce pathogens.[40]
In 2013, the International Scientific Forum on Home Hygiene reviewed 30 studies of the hygiene effectiveness of laundering at temperatures ranging from room temperature to 70°C (158°F), under varying conditions.[41] A key finding was the lack of standardization and control within studies, and the variability in test conditions between studies such as wash cycle time, number of rinses, and other factors. The consequent variability in the data (i.e., the reduction in contamination on fabrics) in turn makes it extremely difficult to propose guidelines for laundering with any confidence. As a result, there is significant variability in the recommendations for hygienic laundering given by different agencies.[42]
Medical hygiene at home
Medical hygiene pertains to hygiene practices that prevent or minimize disease and the spreading of disease in relation to administering medical care to those who are infected or who are more at risk of infection in the home. Members of "at-risk" groups are cared for at home by a carer who may be a household member and who requires a good knowledge of hygiene. People with reduced immunity to infection, who are looked after at home, make up an increasing proportion of the population (as of 2009[update], up to 20%).[9] The largest proportion are the elderly who have co-morbidities that reduce their immunity to infection. It also includes the very young, patients discharged from hospital, taking immuno-suppressive drugs, or using invasive systems, etc. For patients discharged from hospital, or being treated at home, special "medical hygiene" procedures may need to be performed for them, such as catheter or dressing replacement, which puts them at higher risk of infection.
Antiseptics may be applied to cuts, wounds, and abrasions of the skin to prevent the entry of harmful bacteria that can cause sepsis. Day-to-day hygiene practices, other than special medical hygiene procedures,[43] are no different for those at increased risk of infection than for other family members. The difference is that, if hygiene practices are not correctly carried out, the risk of infection is much greater.
Chemical disinfectants[44] are products that kill pathogens. If the product is a disinfectant, the label on the product should say "disinfectant" or "kills" pathogens. Some commercial products, e.g. bleaches, even though they are technically disinfectants, say that they "kill pathogens" but are not actually labelled as "disinfectants". Not all disinfectants kill all types of pathogens. All disinfectants kill bacteria (called bactericidal). Some also kill fungi (fungicidal), bacterial spores (sporicidal), or viruses (virucidal).
An antibacterial product acts against bacteria in some unspecified way. Some products labelled "antibacterial" kill bacteria while others may contain a concentration of active ingredient that only prevents them from multiplying. It is, therefore, important to check whether the product label states that it "kills bacteria". An antibacterial is not necessarily anti-fungal or anti-viral unless this is stated on the label.
The term sanitizer has been used to define substances that both clean and disinfect. More recently this term has been applied to alcohol-based products that disinfect the hands (alcohol hand sanitizers). Alcohol hand sanitizers however are not considered to be effective on soiled hands.[45]
The term biocide is a broad term for a substance that kills, inactivates or otherwise controls living organisms. It includes antiseptics and disinfectants, which combat micro-organisms, and pesticides.
Personal hygiene involves those practices performed by a person to care for their bodily health and well-being through cleanliness. Motivations for personal hygiene practice include reduction of personal illness, healing from illness, optimal health and sense of wellbeing, social acceptance, and prevention of spread of illness to others. What is considered proper personal hygiene can be culture-specific and may change over time.
Practices that are generally considered proper hygiene include showering or bathing regularly, washing hands regularly and especially before handling food, face washing, washing scalp hair, keeping hair short or removing hair, wearing clean clothing, brushing teeth, and trimming fingernails and toenails. Some practices are sex-specific, such as by a woman during menstruation.
Toiletry bags hold body hygiene and toiletry supplies.
Anal hygiene is the practice that a person performs on their anal area after defecation. The anus and buttocks may be either washed with liquids or wiped with toilet paper, or by adding gel wipe to toilet tissue as an alternative to wet wipes or other solid materials in order to remove remnants of feces.
People tend to develop a routine for attending to their personal hygiene needs. Other personal hygienic practices include covering one's mouth when coughing, disposal of soiled tissues appropriately, making sure toilets are clean, and making sure food handling areas are clean, besides other practices. Some cultures do not kiss or shake hands in order to reduce transmission of bacteria by contact.
Personal grooming extends personal hygiene as it pertains to the maintenance of a good personal and public appearance, which need not necessarily be hygienic. It may involve, for example, using deodorants or perfume, shaving, or combing.
Excessive cleaning of the ear canals can result in infection or irritation. The ear canals require less care than other parts of the body because they are sensitive and mostly self-cleaning. There is a slow and orderly migration of the skin lining the ear canal from the eardrum to the outer opening of the ear. Old earwax is constantly being transported from the deeper areas of the ear canal out to the opening where it usually dries, flakes, and falls out.[46] Attempts to clean the ear canals through the removal of earwax can push debris and foreign material into the ear that the natural movement of ear wax out of the ear would have removed.
It is recommended that all healthy adults brush twice a day,[47][48] softly,[49] with the correct technique, replacing their toothbrush every few months (~3).[50]
Teaching a child how to properly brush the teeth
There are a number of common oral hygiene misconceptions. The National Health Service (NHS) of England recommends not rinsing the mouth with water after brushing – only to spit out excess toothpaste. They claim that this helps fluoride from toothpaste bond to teeth for its preventative effects against tooth decay.[51] It is also not recommended to brush immediately after drinking acidic substances, including sparkling water.[52] It is also recommended to floss once a day,[53] with a different piece of floss at each flossing session. The effectiveness of amorphous calcium phosphate products, such as Tooth Mousse, is in debate.[54] Visits to a dentist for a checkup every year at least are recommended.[55]
Sleep hygiene is the recommended behavioral and environmental practices that promote better quality sleep.[56] These recommendations were developed in the late 1970s as a method to help people with mild to moderate insomnia, but, as of 2014[update], the evidence for effectiveness of individual recommendations is "limited and inconclusive".[56] Clinicians assess the sleep hygiene of people who present with insomnia and other conditions, such as depression, and offer recommendations based on the assessment. Sleep hygiene recommendations include establishing a regular sleep schedule, using naps with care, not exercising physically or mentally too close to bedtime, and avoiding alcohol as well as nicotine, caffeine, and other stimulants in the hours before bedtime.[57] Further recommendations include limiting worry, limiting exposure to light in the hours before sleep, getting out of bed if sleep does not come, not using the bed for anything but sleep, and having a peaceful, comfortable, and dark sleep environment.
Personal care services hygiene
Personal care services hygiene pertains to the care and use of instruments used in the administration of personal care services to people:
Personal care hygiene practices include:
sterilization of instruments used by service providers including hairdressers, aestheticians, and other service providers
Excessive body hygiene is a possible sign of obsessive–compulsive disorder. Neglecting bodily hygiene, or the cleanliness of one's environment, may be a sign of major depression and other psychological disorders.
Although media coverage of the hygiene hypothesis has declined, popular folklore continues to sometimes assert that dirt is healthy and hygiene unnatural. This has caused health professionals to be concerned that hygiene behaviors which are the foundation of public health are being undermined. In response to the need for effective hygiene in home and everyday life settings, the International Scientific Forum on Home Hygiene developed a "risk-based" or targeted approach to home hygiene that seeks to ensure that hygiene measures are focused on the places and times most critical for infection transmission.[11] While targeted hygiene was originally developed as an effective approach to hygiene practice, it also seeks, as far as possible, to sustain "normal" levels of exposure to the microbial flora of our environment to the extent that is important to build a balanced immune system.
Although there is substantial evidence that some microbial exposures in early childhood can in some way protect against allergies, there is no evidence[citation needed] that humans need exposure to harmful microbes (infection) or that it is necessary to develop a clinical infection.[58] Nor is there evidence[citation needed] that hygiene measures such as hand washing, food hygiene, etc., are linked to increased susceptibility to atopic disease. If this[ambiguous] is the case, there is no conflict between the goals of preventing infection and minimizing allergies. A consensus is now developing among experts[weaselwords] that the answer lies in more fundamental changes in lifestyles that have led to decreased exposure to certain microbial or other species, such as helminths, that are important for development of immuno-regulatory mechanisms.[59] There is still much uncertainty as to which lifestyle factors are involved.
Medical hygiene
Medical hygiene pertains to hygiene practices related to the administration of medicine and medical care that prevents or minimizes the spread of disease.
Medical hygiene practices include:
isolation of infectious persons or materials to prevent spread of infection
disinfection of reusables (i.e., linen, pads, uniforms)
scrubbing up, handwashing, especially in an operating room, but in more general health-care settings as well, where diseases can be transmitted
ethanol-based sanitizers
Most of these practices were developed in the 19th century and were well-established by the mid-20th century. Some procedures (such as disposal of medical waste) were refined in response to late-20th century disease outbreaks, notably AIDS and Ebola.
Culinary hygiene (or food hygiene) pertains to practices of food management and cooking that prevent food contamination, prevent food poisoning, and minimize the transmission of disease to other foods, humans, or animals. Culinary hygiene practices specify safe ways to handle, store, prepare, serve, and eat food.
Food safety (or food hygiene) is used as a scientific method/discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness. The occurrence of two or more cases of a similar illness resulting from the ingestion of a common food is known as a food-borne disease outbreak.[60] This includes a number of routines that should be followed to avoid potential health hazards. In this way, food safety often overlaps with food defense to prevent harm to consumers. The tracks within this line of thought are safety between industry and the market and then between the market and the consumer. In considering industry-to-market practices, food safety[61] considerations include the origins of food including the practices relating to food labeling, food hygiene, food additives and pesticide residues, as well as policies on biotechnology and food and guidelines for the management of governmental import and export inspection and certification systems for foods. In considering market-to-consumer practices, the usual thought is that food ought to be safe in the market and the concern is safe delivery and preparation of the food for the consumer. Food safety, nutrition and food security are closely related. Unhealthy food creates a cycle of diseases and malnutrition that affects infants and adults as well.[62]
Hygiene aspects in low- and middle-income countries
In developing countries (or low- and middle-income countries), universal access to water and sanitation, coupled with hygiene promotion, is essential in reducing infectious diseases. This approach has been integrated into the Sustainable Development Goal Number 6 whose second target states: "By 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations".[63] Due to their close linkages, water, sanitation, hygiene are together abbreviated and funded under the term WASH in development cooperation.
About two million people die every year due to diarrheal diseases; most of them are children less than five years of age.[64] The most affected are people in developing countries who live in extreme conditions of poverty, normally peri-urban dwellers or rural inhabitants. Providing access to sufficient quantities of safe water and facilities for a sanitary disposal of excreta, and introducing sound hygiene behaviors are important in order to reduce the burden of disease.
Research shows that, if widely practiced, hand washing with soap could reduce diarrhea by almost fifty percent[65] and respiratory infections by nearly twenty-five percent[66] Hand washing with soap also reduces the incidence of skin diseases,[67] and eye infections like trachoma and intestinal worms, especially ascariasis and trichuriasis.[68] Other hygiene practices, such as safe disposal of waste, surface hygiene, and care of domestic animals, are important in low income communities to break the chain of infection transmission.[69]
Cleaning of toilets and hand wash facilities is important to prevent odors and make them socially acceptable. Social acceptance is an important part of encouraging people to use toilets and wash their hands, in situations where open defecation is still seen as a possible alternative, e.g. in rural areas of some developing countries.
Household water treatment and safe storage ensure drinking water is safe for consumption. These interventions are part of the approach of self-supply of water for households.[70]Drinking water quality remains a significant problem in developing[71] and in developed countries;[72] even in the European region it is estimated that 120 million people do not have access to safe drinking water. Point-of-use water quality interventions can reduce diarrheal disease in communities where water quality is poor or in emergency situations where there is a breakdown in water supply.[71][72][73][74] Since water can become contaminated during storage at home (e.g. by contact with contaminated hands or using dirty storage vessels), safe storage of water in the home is important.
Methods for treatment of drinking water at the household level include:[25][74]
chemical disinfection using chlorine or iodine
boiling
filtration using ceramic filters
solar disinfection — Solar disinfection is an effective method, especially when no chemical disinfectants are available.[75]
UV irradiation — Community or household UV systems may be batch or flow-though. The lamps can be suspended above the water channel or submerged in the water flow.
combined flocculation/disinfection systems — available as sachets of powder that act by coagulating and flocculating sediments in water followed by release of chlorine
multibarrier methods — Some systems use two or more of the above treatments in combination or in succession to optimize efficacy.
Bathing culture in Chinese literature can be traced back to the Shang dynasty (1600–1046BCE), when Oracle bone inscriptions describe people washing their hair and body in a bath. The Book of Rites, a work regarding Zhou dynasty (1046–256BCE) ritual, politics, and culture compiled during the Warring States period, recommends that people take a hot shower every five days, and wash their hair every three days. It was also considered good manners to take a bath provided by the host before a dinner. In the Han dynasty, bathing became a regular activity, and for government officials bathing was required every five days.[76]
Ancient bath facilities have been found in ancient Chinese cities, such as Dongzhouyang archaeological site in Henan Province. Bathrooms were called Bi (Chinese:湢), and bathtubs were made of bronze or timber.[77] Bath beans – a powdery soap mixture of ground beans, cloves, eaglewood, flowers, and even powdered jade – were recorded in the Han Dynasty. Bath beans were considered luxury toiletries, while common people simply used powdered beans without spices mixed in. Luxurious bathhouses built around hot springs were recorded in Tang dynasty.[76] While royal bathhouses and bathrooms were common among ancient Chinese nobles and commoners, public bathhouses were a relatively late development. In the Song dynasty (960–1279CE), public bathhouses became popular and people could find them readily.[77]Bathing became an essential part of social life and recreation. Bathhouses often provided massage, nail cutting service, rubdown service, ear cleaning, food, and beverages.[77]Marco Polo, who traveled to China during the Yuan dynasty, noted Chinese bathhouses were using coal to heat the bathhouse, which he had never seen before in Europe.[78] Coal was so plentiful that Chinese people of every social class had bathrooms in their houses, and people took showers every day in the winter for enjoyment.[79]
A typical Ming dynasty bathhouse had slabbed floors and brick domed ceilings. A huge boiler would be installed in the back of the house, connected with the bathing pool through a tunnel. Water could be pumped into the pool by turning wheels attended by the staff.[77]
Japan
The origin of Japanese bathing is misogi, ritual purification with water.[80]
In the Heian period (794–1185CE), houses of prominent families, such as the families of court nobles or samurai, had baths. The bath had lost its religious significance and instead became leisure. Misogi became gyōzui (to bathe in a shallow wooden tub).[80]:36 In the 17th century, the first European visitors to Japan recorded the habit of daily baths in mixed sex groups.[80]
Indian subcontinent
The earliest written account of elaborate codes of hygiene can be found in several Hindu texts, such as the Manusmriti and the Vishnu Purana.[81] Bathing is one of the five nitya karmas (daily duties) in Hinduism, and not performing it leads to sin, according to some scriptures.
Ayurveda is a system of medicine developed in ancient times that is still practiced in India, mostly combined with conventional Western medicine. Contemporary Ayurveda stresses a sattvic diet and good digestion and excretion. Hygiene measures include oil pulling, and tongue scraping. Detoxification also plays an important role.[82]
Spanish chronicles describe the bathing habits of the peoples of Mesoamerica during and after the conquest. Bernal Díaz del Castillo describes Moctezuma (the Mexica, or Aztec, emperor at the arrival of Cortés) in his Historia verdadera de la conquista de la Nueva España as being "...Very neat and cleanly, bathing every day each afternoon...".
Bathing was not restricted to the elite, but was practiced by all people; the chronicler Tomás López Medel wrote after a journey to Central America that " and the custom of washing oneself is so quotidian [common] amongst the Indians, both of cold and hot lands, as is eating, and this is done in fountains and rivers and other water to which they have access, without anything other than pure water..."[83]
The Mesoamerican bath, known as temazcal in Spanish, from the Nahuatl word temazcalli, a compound of temaz ("steam") and calli ("house"), consists of a room, often in the form of a small dome, with an exterior firebox known as texictle (teʃict͜ɬe) that heats a small portion of the room's wall made of volcanic rocks; after this wall has been heated, water is poured on it to produce steam, an action known as tlasas. As the steam accumulates in the upper part of the room a person in charge uses a bough to direct the steam to the bathers who are lying on the ground, with which he later gives them a massage, then the bathers scrub themselves with a small flat river stone and finally the person in charge introduces buckets with water along with soap and grass used to rinse. This bath had also ritual importance, and was tied to the goddess Toci; it is also therapeutic when medicinal herbs are used in the water for the tlasas. It is still used in Mexico.[83]
Regular bathing was a hallmark of Roman civilization.[84] Elaborate baths were constructed in urban areas to serve the public, who typically demanded the infrastructure to maintain personal cleanliness. The complexes usually consisted of large, swimming pool-like baths, smaller cold and hot pools, saunas, and spa-like facilities where people could be depilated, oiled, and massaged. Water was constantly changed by an aqueduct-fed flow. Bathing outside of urban centers involved smaller, less elaborate bathing facilities, or simply the use of clean bodies of water. Roman cities also had large sewers, such as Rome's Cloaca Maxima, into which public and private latrines drained. Romans did not have demand-flush toilets but did have some toilets with a continuous flow of water under them. The Romans used scentedoils (mostly from Egypt), among other alternatives.
In the 11th and 12th centuries, bathing was essential to the Western European upper class: the Cluniac monasteries (popular centers for resorting and retiring) were always equipped with bathhouses. These baths were also used ritually when the monks took full immersion baths at the two Christian festivals of renewal.[96] The rules of the Augustinians and Benedictines contained references to ritual purification,[97] and, inspired by Benedict of Nursia, encouraged the practice of therapeutic bathing. Benedictine monks also played a role in the development and promotion of spas.[98]
On the other hand, bathing also sparked erotic phantasies, played upon by the writers of romances intended for the upper class;[citation needed] in the tale of Melusine the bath was a crucial element of the plot.
Bathing and grooming were regarded with suspicion by moralists, however, because they unveiled the attractiveness of the body. Bathing was said to be a prelude to sin, and in the penitential of Burchard of Worms we find a full catalogue of the sins that ensued when men and women bathed together.[96]
Cities regulated public bathing – the 26 public baths of Paris in the late 13th century were strictly overseen by the civil authorities [96] and guild laws banned prostitutes from bathhouse admission.[99]
In 14th century Tuscany, newlywed couples commonly took a bath together and we find an illustration of this custom in a fresco in the town hall of San Gimignano.[100] As evident in Hans Folz' Bath Booklet (a late 15th century guide on European baths)[101] and various artistic depictions such as Albrecht Dürer's Women's Bath(see above), public bathing continued to be a popular past time in the Renaissance. In Britain, the rise of Protestantism also played a prominent role in the development of spa culture.[98]
Modernity
Until the late 19th century, only the elite in Western cities typically possessed indoor facilities for relieving bodily functions. The poorer majority used communal facilities built above cesspools in backyards and courtyards. This changed after Dr. John Snow discovered that cholera was transmitted by the fecal contamination of water. Though it took decades for his findings to gain wide acceptance, governments and sanitary reformers were eventually convinced of the health benefits of using sewers to keep human waste from contaminating the water. This encouraged the widespread adoption of both the flush toilet and the moral imperative that bathrooms should be indoors and as private as possible.[102][verification needed]
Modern sanitation was not widely adopted until the 19th and 20th centuries. According to medieval historian Lynn Thorndike, people in Medieval Europe probably bathed more than people did in the 19th century.[103][bettersourceneeded] Some time after Louis Pasteur's experiments proved the germ theory of disease and Joseph Lister and others put this into practice in sanitation, hygienic practices came to be regarded as synonymous with health, as they are in modern times.
The importance of hand washing for human health–particularly for people in vulnerable circumstances like mothers who had just given birth or wounded soldiers in hospitals–was first recognized in the mid 19th century by two pioneers of hand hygiene: the Hungarian physician Ignaz Semmelweis who worked in Vienna, Austria, and Florence Nightingale, the English "founder of modern nursing".[104] At that time most people still believed that infections were caused by foul odors called miasmas.
In the Abbasid Caliphate (8th–13th centuries), its capital city of Baghdad (Iraq) had 65,000 baths, along with a sewer system.[108] Cities and towns of the medieval Islamic world had water supply systems powered by hydraulic technology that supplied drinking water along with much greater quantities of water for ritual washing, mainly in mosques and hammams (baths). Bathing establishments in various cities were rated by Arabic writers in travel guides. Medieval Islamic cities such as Baghdad, Córdoba (Islamic Spain), Fez (Morocco), and Fustat (Egypt) also had sophisticated waste disposal and sewage systems with interconnected networks of sewers. The city of Fustat also had multi-storey tenement buildings (with up to six floors) with flush toilets, which were connected to a water supply system, and flues on each floor carrying waste to underground channels.[109]
A basic form of contagion theory dates back to the Persian medicine in the medieval, where it was proposed by Persian physician Ibn Sina (also known as Avicenna) in The Canon of Medicine (1025), the most authoritative medical textbook of the Middle Ages. He mentioned that people can transmit disease to others by breath, noted contagion with tuberculosis, and discussed the transmission of disease through water and dirt.[110] The concept of invisible contagion was eventually widely accepted by Islamic scholars. In the Ayyubid Sultanate, they referred to them as najasat ("impure substances"). The fiqh scholar Ibn al-Haj al-Abdari (c.1250–1336), while discussing Islamic diet and hygiene, gave advice and warnings about how contagion can contaminate water, food, and garments, and could spread through the water supply.[111]
In the 9th century, Ziryab invented a type of deodorant.[112] He also promoted morning and evening baths, and emphasized the maintenance of personal hygiene. Ziryab is thought to have invented a type of toothpaste, which he popularized throughout Islamic Iberia.[113] The exact ingredients of this toothpaste are not known,[114] but it was reported to have been both "functional and pleasant to taste."[113]
Hard toilet soap with a pleasant smell was invented in the Middle East during the Islamic Golden Age when soap-making became an established industry. Recipes for soap-making are described by Muhammad ibn Zakariya al-Razi (c.865–925), who also gave a recipe for producing glycerine from olive oil. In the Middle East, soap was produced from the interaction of fatty oils and fats with alkali. In Syria, soap was produced using olive oil together with alkali and lime. Soap was exported from Syria to other parts of the Muslim world and to Europe.[117] Two key Islamic innovations in soapmaking was the invention of bar soap, described by al-Razi, and the addition of scents using perfume technology perfected in the Islamic world.[118]
By the 15th century, the manufacture of soap in Christendom had become virtually industrialized, with sources in Antwerp, Castile, Marseille, Naples, and Venice.[119] In the 17th century the Spanish Catholic manufacturers purchased the monopoly on Castile soap from the cash-strapped Carolinian government.[120] Industrially-manufactured bar soaps became available in the late 18th century, as advertising campaigns in Europe and America promoted popular awareness of the relationship between cleanliness and health.[121]
Many religions require or encourage ritual purification via bathing or immersing the hands in water. In Islam, washing oneself via wudu or ghusl is necessary for performing prayer. Islamic tradition also lists a variety of rules concerning proper hygiene after using the bathroom. The Baháʼí Faith mandates the washing of the hands and face prior to the obligatory Baháʼí prayers. Orthodox Judaism requires a mikveh bath following menstruation and childbirth, while washing the hands is performed upon waking up and before eating bread. Water plays a role in Christian rituals as well,[130] and in certain denominations of Christianity such as the Ethiopian Orthodox Tewahedo Church which prescribes several kinds of hand washing for example after leaving the latrine, lavatory, or bathhouse, or before prayer, or after eating a meal, or ritual handwashing.[131][130]
Etymology
First attested in English in 1676, the word hygiene comes from the Frenchhygiène, the latinisation of the Greekὑγιεινή (τέχνη) hygieinē technē, meaning "(art) of health", from ὑγιεινόςhygieinos, "good for the health, healthy",[132] in turn from ὑγιής (hygiēs), "healthful, sound, salutary, wholesome".[133] In ancient Greek religion, Hygeia (Ὑγίεια) was the personification of health, cleanliness, and hygiene.[134]

In Christianity, ablution is a prescribed washing of part or all of the body or possessions, such as clothing or ceremonial objects, with the intent of purification or dedication. In Christianity, both baptism and footwashing are forms of ablution. Prior to praying the canonical hours at seven fixed prayer times, Oriental Orthodox Christians wash their hands and face. In liturgical churches, ablution can refer to purifying fingers or vessels related to the Eucharist. In the New Testament, washing also occurs in reference to rites of Judaism part of the action of a healing by Jesus, the preparation of a body for burial, the washing of nets by fishermen, a person's personal washing of the face to appear in public, the cleansing of an injured person's wounds, Pontius Pilate's washing of his hands as a symbolic claim of innocence and foot washing, which is a rite within the Christian Churches. According to the Gospel of Matthew, Pontius Pilate declared himself innocent of the blood of Jesus by washing his hands. This act of Pilate may not, however, have been borrowed from the custom of the Jews. The same practice was common among the Greeks and Romans.
Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route. For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through adequate sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis, cholera, hepatitis, polio, schistosomiasis, and trachoma, to name just a few.
An intestinal parasite infection is a condition in which a parasite infects the gastro-intestinal tract of humans and other animals. Such parasites can live anywhere in the body, but most prefer the intestinal wall.
Washing is a method of cleaning, usually with water and soap or detergent. Regularly washing and then rinsing both body and clothing is an essential part of good hygiene and health.
Cleanliness is both the state of being clean and free from germs, dirt, trash, or waste, and the habit of achieving and maintaining that state. Cleanliness is often achieved through cleaning. Culturally, cleanliness is usually a good quality, as indicated by the aphorism: "Cleanliness is next to Godliness", and may be regarded as contributing to other ideals such as health and beauty.
In medicine, the hygiene hypothesis states that early childhood exposure to particular microorganisms protects against allergies by properly tuning the immune system. In particular, a lack of such exposure is thought to lead to poor immune tolerance. The time period for exposure begins before birth and ends at school age.
The fecal–oral route describes a particular route of transmission of a disease wherein pathogens in fecal particles pass from one person to the mouth of another person. Main causes of fecal–oral disease transmission include lack of adequate sanitation, and poor hygiene practices. If soil or water bodies are polluted with fecal material, humans can be infected with waterborne diseases or soil-transmitted diseases. Fecal contamination of food is another form of fecal-oral transmission. Washing hands properly after changing a baby's diaper or after performing anal hygiene can prevent foodborne illness from spreading.
Hand washing, also known as hand hygiene, is the act of cleaning one's hands with soap or handwash and water to remove viruses/bacteria/microorganisms, dirt, grease, and other harmful or unwanted substances stuck to the hands. Drying of the washed hands is part of the process as wet and moist hands are more easily recontaminated. If soap and water are unavailable, hand sanitizer that is at least 60% (v/v) alcohol in water can be used as long as hands are not visibly excessively dirty or greasy. Hand hygiene is central to preventing the spread of infectious diseases in home and everyday life settings.
Bathing is the immersion of the body, wholly or partially, usually in water, but often in another medium such as hot air. It is most commonly practised as part of personal cleansing, and less frequently for relaxation or as a leisure activity. Cleansing the body may be solely a component of personal hygiene, but is also a spiritual part of some religious rituals. Bathing is also sometimes used medically or therapeutically, as in hydrotherapy, ice baths, or the mud bath.
Public baths originated when most people in population centers did not have access to private bathing facilities. Though termed "public", they have often been restricted according to gender, religious affiliation, personal membership, and other criteria.
A spa is a location where mineral-rich spring water is used to give medicinal baths. Spa health treatments are known as balneotherapy. The belief in the curative powers of mineral waters and hot springs goes back to prehistoric times. Spa towns, spa resorts, and day spas are popular worldwide, but are especially widespread in Europe and Japan.
Infection prevention and control is the discipline concerned with preventing healthcare-associated infections; a practical rather than academic sub-discipline of epidemiology. In Northern Europe, infection prevention and control is expanded from healthcare into a component in public health, known as "infection protection". It is an essential part of the infrastructure of health care. Infection control and hospital epidemiology are akin to public health practice, practiced within the confines of a particular health-care delivery system rather than directed at society as a whole.
Bathing played a major part in ancient Roman culture and society. It was one of the most common daily activities and was practiced across a wide variety of social classes. Though many contemporary cultures see bathing as a private activity conducted in the home, bathing in Rome was a communal activity. While the extremely wealthy could afford bathing facilities in their homes, private baths were very uncommon, and most people bathed in the communal baths (thermae). In some ways, these resembled modern-day destination spas as there were facilities for a variety of activities from exercising to sunbathing to swimming and massage.
Anal hygiene refers to practices that are performed on the anus to maintain personal hygiene, usually immediately or shortly after defecation. Anal cleansing may also occur while showering or bathing. Post-defecation cleansing is rarely discussed academically, partly due to the social taboo surrounding it. The scientific objective of post-defecation cleansing is to prevent exposure to pathogens.
In health care facilities, isolation represents one of several measures that can be taken to implement in infection control: the prevention of communicable diseases from being transmitted from a patient to other patients, health care workers, and visitors, or from outsiders to a particular patient. Various forms of isolation exist, in some of which contact procedures are modified, and others in which the patient is kept away from all other people. In a system devised, and periodically revised, by the U.S. Centers for Disease Control and Prevention (CDC), various levels of patient isolation comprise application of one or more formally described "precaution".
Global Hand washing Day (GHD) is an international hand washing promotion campaign to motivate and mobilize people around the world to improve their hand washing habits. Washing hands at critical points both during the day and washing with soap are important. In 2008, Global Handwashing Day was celebrated for the first time. This day aims to make people around the world aware of the importance of washing their hands with soap in order to prevent diseases and infections. To commem.orate this special day, over 120 million children in 70 countries were encouraged to practice handwashing with soap. Since then, the movement has built momentum, garnering support from various stakeholders such as governments, schools, NGOs, and private firms.
WASH is a sector in development cooperation or within local governments that provides water, sanitation, and hygiene services to people. The main purposes of providing access to WASH services includes achieving public health gains, implementing the human right to water and sanitation, reducing the burden of collecting drinking water for women, and improving education and health outcomes at schools and health facilities. Access to WASH services is also an important component of water security. Universal, affordable, and sustainable access to WASH is a key issue within international development and is the focus of the first two targets of Sustainable Development Goal 6. Targets 6.1 and 6.2 aim for equitable and accessible water and sanitation for all. In 2017, it was estimated that 2.3 billion people live without basic sanitation facilities, and 844 million people live without access to safe and clean drinking water. The acronym WASH is used widely by non-governmental organizations and aid agencies in developing countries.
A toilet is a small room used for privately accessing the sanitation fixture (toilet) for urination and defecation. Toilet rooms often include a sink (basin) with soap/handwash for handwashing, as this is important for personal hygiene. These rooms are typically referred to in North America as half-bathrooms in a private residence.
Jewelry hygiene is an area of study focusing on sanitary practices and habits relating to jewelry in an effort to understand jewelry's effect on hand hygiene. There are four key elements to optimally sanitizing jewelry: steam or hot water, water pressure and an antibacterial cleaning agent. Hand hygiene is particularly acute for health workers and those working in the food service industry.
In some denominations of Christianity, there are a number of regulations involving cleanliness before prayer, observing days of ritual purification, as well as those concerning diet and apparel. The Bible has many rituals of purification in areas ranging from the mundane private rituals of personal hygiene and toilet etiquette to the complex public rituals of social etiquette.
