Targeted temperature management (TTM), previously known as therapeutic hypothermia or protective hypothermia, is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain.

Consequently, during the next two decades studies of neonatal hypothermia in Europe and the USA were sporadic and often unsuccessful. An interest in cooling for brain protection was beginning to emerge, but contemporary neuroscience provided few useful concepts to guide this research and little progress was made.
The law holds well for forced air and pumped liquid cooling, where the fluid velocity does not rise with increasing temperature difference. Newton's law is most closely obeyed in purely conduction-type cooling. However, the heat transfer coefficient is a function of the temperature difference in natural convective (buoyancy driven) heat transfer.
A hypothermia cap (also referred to as cold cap or cooling cap) is a therapeutic device used to cool the human scalp. Its most prominent medical applications are in preventing or reducing alopecia in chemotherapy , and for preventing cerebral palsy in babies born with neonatal encephalopathy caused by hypoxic-ischemic encephalopathy (HIE) .
People caught in very cold, snowy conditions can build an igloo or snow cave to shelter. [58] [59] The United States Coast Guard promotes using life vests to protect against hypothermia through the 50/50/50 rule: If someone is in 10 °C (50 °F) water for 50 minutes, they have a 50 percent better chance of survival if they are wearing a life ...

Example Consider a component such as a silicon transistor that is bolted to the metal frame of a piece of equipment. The transistor's manufacturer will specify parameters in the datasheet called the absolute thermal resistance from junction to case (symbol: R θ J C {\displaystyle R_{\theta {\rm {JC}}}} ), and the maximum allowable temperature ...
In the field, the person should be moved to a cool area, such as indoors or to a shaded area. Clothing should be removed to promote heat loss through passive cooling. Conductive cooling methods such as ice-water immersion should also be used, if possible. Evaporative and convective cooling by a combination of cool water spray or cold compresses ...
