Exercise 12

What is a clo unit, and why is the insulation requirement less when you exercise?

Step 1 of 3

Hypothermia is a condition in which the core body temperature is below 35^o C. The condition occurs when the rate of heat loss from the body exceeds the rate of heat production.

The rate of heat loss from the body is inversely related to insulation between body parts and the environment. The main insulating factor of the body is the subcutaneous fat. Clothing that prevents heat loss also acts as an insulator.
