Miliaria, commonly known as heat rash, sweat rash, or prickly heat, [1] is a skin disease marked by small, itchy rashes due to sweat trapped under the skin by clogged sweat-gland ducts. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer. [ 2 ]
An aerosol frostbite of the skin is an injury to the body caused by the pressurized gas within an aerosol spray cooling quickly, with the sudden drop in temperature sufficient to cause frostbite to the applied area. [1] Medical studies have noted an increase of this practice, known as "frosting", in pediatric and teenage patients. [2] [3]
A medical thermometer or clinical thermometer is a device used for measuring the body temperature of a human or other animal. The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal ...
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
When heat comes from a direct contact source it has to heat the external layer of the skin, and heat is transferred to the deeper layer by conduction. Since heat conduction needs a temperature gradient to proceed, and there is a maximum temperature that can be safely used (around 42 °C), this means lower temperature where warming is needed.
A 2022 study on the effect of heat on young people found that the critical wet-bulb temperature at which heat stress can no longer be compensated, T wb,crit, in young, healthy adults performing tasks at modest metabolic rates mimicking basic activities of daily life was much lower than the 35 °C (95 °F) usually assumed, at about 30.55 °C (86 ...
Setzer says she noticed hundreds of tiny black dots all over her daughter's legs, abdomen, arms and armpit area after she had come inside for a nap after "rolling around on the ground while ...
Cryotherapy is a specific type of low-temperature treatment used to reduce inflammation and its associated pain. [ 4 ] Cryotherapy was developed in the 1970s by Japanese rheumatologist Toshima Yamaguchi [ 5 ] [ 6 ] and introduced to Europe, US and Australia in the 1980s [ 7 ] [ 8 ] and 1990s.
