The sleeping position is the body configuration assumed by a person during or prior to sleeping. It has been shown to have health implications, particularly for babies.
A Canadian survey found that 39% of respondents preferring the "log" position (lying on one's side with the arms down the side) and 28% preferring to sleep on their side with their legs bent. [1]
A Travelodge survey found that 50% of heterosexual British couples prefer sleeping back-to-back, either not touching (27%) or touching (23%). Spooning was next, with the man on the outside 20% of the time vs. 8% with the woman on the outside. 10% favoured the "lovers' knot" (facing each other with legs intertwined), though all but 2% separated before going to sleep. The "Hollywood pose" of the woman with her head and arm on the man's chest was chosen by 4%. [2]
In the 1958 edition of his best-selling book The Common Sense Book of Baby and Child Care , paediatrician Dr Benjamin Spock warned against placing a baby on its back, writing, "if [an infant] vomits, he's more likely to choke on the vomitus." However, later studies have shown that placing a young baby in a face-down prone position increases the risk of sudden infant death syndrome (SIDS). A 2005 study concluded that "systematic review of preventable risk factors for SIDS from 1970 would have led to earlier recognition of the risks of sleeping on the front and might have prevented over 10,000 infant deaths in the UK and at least 50,000 in Europe, the USA, and Australasia."

The brain parenchyma rids itself of harmful proteins through the glymphatic system, especially during sleep. [4]
Snoring, which may be (but is not necessarily) an indicator of obstructive sleep apnea, may also be alleviated by sleeping on one's side. [5]
The right lateral sleeping position results in much more reflux in the night than the left lateral position and prone position. [6] [7]
Sleeping in the supine position has been linked to an increased occurrence of sleep paralysis. [8]
Sleep apnea is a sleep-related breathing disorder in which repetitive pauses in breathing, periods of shallow breathing, or collapse of the upper airway during sleep results in poor ventilation and sleep disruption. Each pause in breathing can last for a few seconds to a few minutes and occurs many times a night. A choking or snorting sound may occur as breathing resumes. Common symptoms include daytime sleepiness, snoring, and non restorative sleep despite adequate sleep time. Because the disorder disrupts normal sleep, those affected may experience sleepiness or feel tired during the day. It is often a chronic condition.
A sleep disorder, or somnipathy, is a medical disorder of an individual's sleep patterns. Some sleep disorders are severe enough to interfere with normal physical, mental, social and emotional functioning. Sleep disorders are frequent and can have serious consequences on patients' health and quality of life. Polysomnography and actigraphy are tests commonly ordered for diagnosing sleep disorders.
Sudden infant death syndrome (SIDS), sometimes known as cot death, is the sudden unexplained death of a child of less than one year of age. Diagnosis requires that the death remain unexplained even after a thorough autopsy and detailed death scene investigation. SIDS usually occurs during sleep. Typically death occurs between the hours of midnight and 9:00a.m. There is usually no noise or evidence of struggle. SIDS remains the leading cause of infant mortality in Western countries, constituting half of all post-neonatal deaths.
Gastroesophageal reflux disease (GERD) or gastro-oesophageal reflux disease (GORD) is a chronic upper gastrointestinal disease in which stomach content persistently and regularly flows up into the esophagus, resulting in symptoms and/or complications. Symptoms include dental corrosion, dysphagia, heartburn, odynophagia, regurgitation, non-cardiac chest pain, extraesophageal symptoms such as chronic cough, hoarseness, reflux-induced laryngitis, or asthma. In the long term, and when not treated, complications such as esophagitis, esophageal stricture, and Barrett's esophagus may arise.
Snoring is the vibration of respiratory structures and the resulting sound due to obstructed air movement during breathing while sleeping. The sound may be soft or loud and unpleasant. Snoring during sleep may be a sign, or first alarm, of obstructive sleep apnea (OSA). Research suggests that snoring is one of the factors of sleep deprivation.
Co-sleeping or bed sharing is a practice in which babies and young children sleep close to one or both parents, as opposed to in a separate room. Co-sleeping individuals sleep in sensory proximity to one another, where the individual senses the presence of others. This sensory proximity can either be triggered by touch, smell, taste, or noise. Therefore, the individuals can be a few centimeters away or on the other side of the room and still have an effect on the other. It is standard practice in many parts of the world, and is practiced by a significant minority in countries where cribs are also used.
Nasal congestion is the partial or complete blockage of nasal passages, leading to impaired nasal breathing, usually due to membranes lining the nose becoming swollen from inflammation of blood vessels.
Swaddling is an ancient practice of wrapping infants in blankets or similar cloths so that movement of the limbs is tightly restricted. Swaddling bands were often used to further restrict the infant. Swaddling fell out of favour in the 17th century.
Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder and is characterized by recurrent episodes of complete or partial obstruction of the upper airway leading to reduced or absent breathing during sleep. These episodes are termed "apneas" with complete or near-complete cessation of breathing, or "hypopneas" when the reduction in breathing is partial. In either case, a fall in blood oxygen saturation, a disruption in sleep, or both, may result. A high frequency of apneas or hypopneas during sleep may interfere with the quality of sleep, which – in combination with disturbances in blood oxygenation – is thought to contribute to negative consequences to health and quality of life. The terms obstructive sleep apnea syndrome (OSAS) or obstructive sleep apnea–hypopnea syndrome (OSAHS) may be used to refer to OSA when it is associated with symptoms during the daytime.
The supine position means lying horizontally with the face and torso facing up, as opposed to the prone position, which is face down. When used in surgical procedures, it grants access to the peritoneal, thoracic and pericardial regions; as well as the head, neck and extremities.
Apnea of prematurity is a disorder in infants who are preterm that is defined as cessation of breathing by that lasts for more than 20 seconds and/or is accompanied by hypoxia or bradycardia. Apnea of prematurity is often linked to earlier prematurity. Apnea is traditionally classified as either obstructive, central, or mixed. Obstructive apnea may occur when the infant's neck is hyperflexed or conversely, hyperextended. It may also occur due to low pharyngeal muscle tone or to inflammation of the soft tissues, which can block the flow of air though the pharynx and vocal cords. Central apnea occurs when there is a lack of respiratory effort. This may result from central nervous system immaturity, or from the effects of medications or illness. Many episodes of apnea of prematurity may start as either obstructive or central, but then involve elements of both, becoming mixed in nature.
The Safe to Sleep campaign, formerly known as the Back to Sleep campaign, is an initiative backed by the US National Institute of Child Health and Human Development (NICHD) at the US National Institutes of Health to encourage parents to have their infants sleep on their backs to reduce the risk of sudden infant death syndrome, or SIDS. The target age group of the campaign is 0–1 years of age, because this is when babies are at the greatest risk of experiencing SIDS. Since "Safe to Sleep" was launched in 1994, the incidence of SIDS has declined by more than 50%. However, there has been a rise in infant sleep-related suffocation events. Consequently, the campaign has broadened its goal to focus on safe sleep conditions and further preventative measures.
Tummy time is a colloquialism for placing infants in the prone position while awake and supervised to encourage development of the neck and trunk muscles and prevent skull deformations.
An orthopedic pillow is a pillow designed to correct body positioning in bed or while lying on any other surface. Its design conforms to orthopedic guidelines to ensure the right placement and support of one or more specific parts of the body to provide safe and healthy rest to the sleeper.
Central sleep apnea (CSA) or central sleep apnea syndrome (CSAS) is a sleep-related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds either intermittently or in cycles, and is usually associated with a reduction in blood oxygen saturation. CSA is usually due to an instability in the body's feedback mechanisms that control respiration. Central sleep apnea can also be an indicator of Arnold–Chiari malformation.
Sleep training is a set of parental intervention techniques with the end goal of increasing nightly sleep in infants and young children, addressing “sleep concerns”, and decreasing nighttime signalling. Although the diagnostic criteria for sleep issues in infants is rare and limited, sleep training is usually approached by parents or caregivers self identifying supposed sleep issues.
Brief resolved unexplained event (BRUE), previously apparent life-threatening event (ALTE), is a medical term in pediatrics that describes an event that occurs during infancy. The event is noted by an observer, typically the infant's caregiver. It is characterized by one or more concerning symptoms such as change in skin color, lack of breathing, weakness, or poor responsiveness. By definition, by the time they are assessed in a healthcare environment they must be back to normal without obvious explanation after the clinician takes the appropriate clinical history and physical examination.
Infantile apnea is a rare disease that is characterized by cessation of breathing in an infant for at least 20 seconds or a shorter respiratory pause that is associated with a slow heart rate, bluish discolouration of the skin, extreme paleness, gagging, choking and/or decreased muscle tone. Infantile apnea occurs in children under the age of one and it is more common in premature infants. Symptoms of infantile apnea occur most frequently during the rapid eye movement (REM) stage of sleep. The nature and severity of breathing problems in patients can be detected in a sleep study called a polysomnography which measures the brain waves, heartbeat, body movements and breathing of a patient overnight. Infantile apnea can be caused by developmental problems that result in an immature brainstem or it can be caused other medical conditions. As children grow and develop, infantile apnea usually does not persist. Infantile apnea may be related to some cases of sudden infant death syndrome (SIDS) however, the relationship between infantile apnea and SIDS is not known.
A bedside sleeper, also referred to as a sidecar sleeper or bedside bassinet, is a bassinet or baby cot that attaches to the parents' bed, allowing newborns to sleep next to their parents safely. This is a form of safe co-sleeping, and has little risks associated with sudden infant death syndrome, unlike bedsharing. Bedside sleepers are a component of rooming-in, a practice followed in hospitals to keep the baby by the mother's bed, giving her time to establish a stronger bond with her baby.
Infant and toddler safety are those actions and modifications put into place to keep babies and toddlers safe from accidental injury and death. Many accidents, injuries and deaths are preventable.
