Question

What are hot and cold skin receptors?

Answer 1

Cold skin receptors:

1. Cold receptors begin to perceive cold feelings when the skin surface temperature falls below 95^o F.
2. It is primarily activated when the skin's surface temperature is over 71^oF and is no longer triggered when the skin's surface temperature falls below 41^o F.
3. As a result, when submerged in cold water for extended periods of time, one's hands or feet begin to feel numb.

Hot skin receptors:

1. Hot receptors begin to perceive hot feelings when the skin's surface temperature increases over 86^oF.
2. They are activated at 113^oF.
3. Pain receptors dominate above this temperature to protect the skin and tissues beneath.
