The Hot Yoga Balancing Act: Heat and Humidity
Yes, it's hot in the hot yoga room - so it's cool to read how your hot little body cools down to keep you safe and strong in your 90 minute hot box called hot yoga class.
Cool to the Core
Your body maintains its core temperature at 98.6º F (37º C) by balancing the rate of internal heat production with heat loss to the environment. This little balancing act is called thermoregulation.
Thermoregulation is challenging in any heated environment, especially if the air temperature is greater than the skin temperature. During moderate exercise, core body temperature rises and the additional heat must be moved from the core to the skin.
Heat is removed from the body to the environment in four ways: radiation, conduction, convection, and evaporation. The first three occur in environments where air temperature is cooler than skin temperature or where cooler air blows over the skin. The hot yoga room is typically heated to 105º F which exceeds skin temperature, and possibly above core temperature when you're practicing.
