Question

When environmental air temperature exceeds skin temperature

a. heat gain can occur in the body through convection and/or radiation.
b. the sweat rate decreases.
c. heat is lost from the body via convection.
d. None of these answers is correct.

Answer 1

When the environmental air temperature exceeds the skin temperature, heat can be lost from the body through convection and radiation.

Step-by-step explanation:

When the environmental air temperature exceeds the skin temperature, several heat exchange mechanisms come into play. Convection is one of these mechanisms, where heat is transferred to the air surrounding the skin. The warmed air rises away from the body and is replaced by cooler air, allowing heat loss from the body. Additionally, radiation is another mechanism through which the body loses heat to the environment. When the air temperature is higher than the skin temperature, heat can be lost through radiation.
