Temperature play is a form of BDSM sensual play where objects and substances are used to stimulate the body's neuroreceptors for heat and cold for sensual effect.
Substances can include water, oil, molten wax, ice, chocolate syrup, whipped cream, melted butter, chilled fresh fruit and steamed vegetables.
Objects can include cutlery, ball chains, necklaces and many others, often pre-heated in hot water or chilled in ice water. Space heaters, radiators, and other sources of heat can also be used for stimulating sensory arousal with heat.
Blindfolds are often used to intensify the effects, and bondage can also amplify the experience.
General scenarios are placing the person in a situation where they are exposed to heat and cold conditions more directly.
Safety precautions should be used which are appropriate for the materials, techniques and body parts involved.
Fire play is a form of temperature play that involves using flame on or very close to, the skin. The flame is typically on or applied with a fire wand (essentially a small torch), and frequently utilizes 70% isopropyl alcohol as fuel. Other common fire play toys include flaming gloves and flaming floggers; other common varieties of fuel include 91% isopropyl alcohol, mousse, hand sanitizer, super-proof rum, grain alcohol, and flash cotton. As with many forms of BDSM play, the proper tools, fuels, and safety guidelines are often in hot contention between players.
Fire play is usually considered a form of edge play - frequently exciting, but with significant dangers. Unlike other forms of edge play (extreme rough body play, blood play, interrogations, abductions, etc.), fire play scenes tend to look kinder and gentler; although it can be dramatic, the sensations inflicted in most fire play scenes aren't actually painful (much like hot wax play or sensation play). Fire play also rarely leaves marks on the skin - though some people deliberately burn the skin slightly to leave it red and irritated.
The two most common fire play techniques are bouncing and streaking. In bouncing, lit fire wands (sometimes called batons; essentially a small torch) are bounced along the skin. This may or may not involve transfer of burning fuel.
In streaking, fuel is applied directly to the skin (commonly in straight lines, though sometimes in more elaborate patterns), lit, and then extinguished before the skin begins to burn. Frequently the fuel is applied to the skin with unlit fire wands, then ignited with a lit fire wand (sometimes double-headed wands or two wands are used to streamline the procedure).
Fire cupping is where the air inside a cup (almost always glass) is heated then placed on the skin - the cooling air creates a low-pressure pocket that pulls the skin partially into the cup. Experienced cuppers can create varying strengths of suction by controlling the heat of the cup.
Fire cupping was appropriated from traditional and holistic medicine communities. Cupping was used in Western medicine to encourage blood movement as recently as the American Civil War. It is still used (often with the same name) by masseurs and in Chinese medicine (where it is said to have predated traditional needle acupuncture) as well as in traditional Arab medicine. For this reason, cupping sets can be found in some Asian stores. Some merchants will only sell sets to licensed massage therapists.
Fire cupping typically leaves small, round marks on the body that may last for hours or for days. If a single area is cupped again and again, a deep bruise may form and not disappear for some time.
Fire cupping is often combined with blood play, and is then usually termed blood- or wet-cupping. (This variant also comes from traditional medicine). The skin is pierced (commonly with needles or scalpels) before the cups are applied; the suction then draws blood out of the wound.
Ice play is a form of temperature play that usually involves running pieces of ice across a person's naked skin. In popular culture this form of cold temperature play is frequently shown as foreplay to suggest sex with a flair of kink/interest but which may not be classed as BDSM - see movies such as Do the Right Thing, and 9½ Weeks. In BDSM, it's not uncommon for ice play to be used more elaborately. Ice is sometimes used as an insertable (for the vagina, anus, and occasionally for the male urethra), but this is risky because ice, as it melts, can form edges sharp enough to cut skin or tender tissues. Part or all of the body may be immersed in ice or ice water for short periods of time (longer periods of time run the risk of hypothermia and frostbite). Ice may be used to provide contrast in a scene that also involves warm or hot stimuli.
Exposure to heat and cold conditions is often employed. These are usually extremes of either of these not usually experienced on an everyday basis.
One of the simplest ways to engage in cold and heat exposure is with metal and glass sex toys that are built to withstand temperature play. These toys can either be placed in the fridge for cold exposure or inside a sex toy warming pouch for heat exposure.
A common and easily employed type of cold torture is to make subjects stand or lay naked in snow. This can be either freely or tied up. Where a subject is tied it may be in a stretched or splayed out position to expose as much of the body to the extreme condition. A variant of cold exposure is to water down a subject with cold water in cold or windy conditions or employing fans. The risks of cold exposure are hypothermia and frostbite.
Common methods of heat torture are to wrap a subject in plastic wrap, blankets, or leather or pvc bodysuits, usually with their legs together and their arms next to their body. Other methods include physical activity in severe heat or sun exposure. Lesser used methods employ heaters, fire or coals (known as roasting) for direct exposure to extreme heat. Other physical tortures such as electric shock are sometimes applied at the same time to make the subject exert themselves in order to generate more body heat. The main risk of heat exposure is dehydration but under extreme conditions heatstroke can also occur.
With both heat and cold exposure other torture methods are sometimes applied at the same time. General heat and cold exposure may be used as foreplay where during which intercourse occurs or orgasm is induced.
Hyperthermia, also known simply as overheating, is a condition where an individual's body temperature is elevated beyond normal due to failed thermoregulation. The person's body produces or absorbs more heat than it dissipates. When extreme temperature elevation occurs, it becomes a medical emergency requiring immediate treatment to prevent disability or death. Almost half a million deaths are recorded every year from hyperthermia.
Bondage, in the BDSM subculture, is the practice of consensually tying, binding, or restraining a partner for erotic, aesthetic, or somatosensory stimulation. A partner may be physically restrained in a variety of ways, including the use of rope, cuffs, bondage tape, or self-adhering bandage.
Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping.
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system.
Frostbite is a skin injury that occurs when exposed to extreme low temperatures, causing the freezing of the skin or other tissues, most commonly affecting the fingers, toes, nose, ears, cheeks and chin areas. The initial symptom is typically numbness. This may be followed by clumsiness with a white or bluish color to the skin. Swelling or blistering may occur following treatment. The hands, feet, and face are most commonly affected. Complications may include hypothermia or compartment syndrome.
Bondage is the activity of tying or restraining people using equipment such as chains, cuffs, or collars for mutual erotic pleasure. According to the Kinsey Institute, 12% of females and 22% of males respond erotically to BDSM.
Fractional freezing is a process used in process engineering and chemistry to separate substances with different melting points. It can be done by partial melting of a solid, for example in zone refining of silicon or metals, or by partial crystallization of a liquid, as in freeze distillation, also called normal freezing or progressive freezing. The initial sample is thus fractionated.
Fire performance is a group of performance arts or skills that involve the manipulation of fire. Fire performance typically involves equipment or other objects made with one or more wicks which are designed to sustain a large enough flame to create a visual effect.
Cupping therapy is a form of alternative medicine in which a local suction is created on the skin with the application of heated cups. Its practice mainly occurs in Asia but also in Eastern Europe, the Middle East, and Latin America. Cupping has been characterized as a pseudoscience and its practice as quackery.
Cryotherapy, sometimes known as cold therapy, is the local or general use of low temperatures in medical therapy. Cryotherapy may be used to treat a variety of tissue lesions. The most prominent use of the term refers to the surgical treatment, specifically known as cryosurgery or cryoablation. Cryosurgery is the application of extremely low temperatures to destroy abnormal or diseased tissue and is used most commonly to treat skin conditions.
This glossary of BDSM terms defines terms commonly used in the BDSM community.
Maceration is the winemaking process where the phenolic materials of the grape—tannins, coloring agents (anthocyanins) and flavor compounds—are leached from the grape skins, seeds and stems into the must. To macerate is to soften by soaking, and maceration is the process by which the red wine receives its red color, since raw grape juice is clear-grayish in color. In the production of white wines, maceration is either avoided or allowed only in very limited manner in the form of a short amount of skin contact with the juice prior to pressing. This is more common in the production of varietals with less natural flavor and body structure like Sauvignon blanc and Sémillon. For Rosé, red wine grapes are allowed some maceration between the skins and must, but not to the extent of red wine production.

Electric heating is a process in which electrical energy is converted to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy. Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators.
Coffee preparation is the process of turning coffee beans into a beverage. While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps: raw coffee beans must be roasted, the roasted coffee beans must then be ground, the ground coffee must then be mixed with hot water for a certain time (brewed), and finally the liquid coffee must be separated from the used grounds.
A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail a host of other criteria, involving other evidence of functionality or fitness for purpose.
Normal human body-temperature is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37 °C (97.7–98.6 °F).
The conservation and restoration of parchment constitutes the care and treatment of parchment materials which have cultural and historical significance. Typically undertaken by professional book and document conservators, this process can include preventive measures which protect against future deterioration as well as specific treatments to alleviate changes already caused by agents of deterioration.
A truckmount carpet cleaner is a carpet and upholstery cleaning unit that is generally mounted to the floor of a van or trailer. Its cleaning method is hot water extraction. The operator would park the van near the premises, connect the vacuum hose and solution line hose into the machine, bring the hoses into the building, and connect a carpet cleaning wand to the end of the hoses.
Heat stroke, also known as sun stroke, is a type of severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F) and confusion. Other symptoms include red skin, headache, and dizziness. There is generally a lack of sweating in classic heat stroke while sweating is generally present in exertional heatstroke. The start of heat stroke can be sudden or gradual. Heatstroke is a life-threatening condition characterized by severe hyperthermia and multiorgan-dysfunction resulting from exposure to heat. Medical complications may include seizures, rhabdomyolysis, or kidney failure.
