HEAT ACCLIMATION

Adaptation to repeated exposure in a simulated hot environment, usually used to prepare for exercise or competition in heat.

Common responses can include an earlier sweat response and lower cardiovascular or perceptual strain during exercise in heat. Expert consensus commonly describes progressive exposure over roughly one to two weeks, but studies use different methods and populations. It does not establish one sauna, room-temperature or core-temperature prescription, and performance gains in cool conditions are uncertain.
