Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

During exercise the skin reddens because ____

A	Sweat is red
B	Capillaries close to the surface expand to release heat
C	The skin is cold
D	None of the above

Explanation:

Detailed explanation-1: -Your heart will beat faster, which increases blood flow to your muscles. Your small blood vessels will widen to deliver more oxygen to your muscles and carry away carbon dioxide and other waste products that build up. It is this widening of the blood vessels that causes the flushing of your skin during exercise!

Detailed explanation-2: -The heat generated in contracting muscles is transferred, because of circulation of blood, to the skin surface; thus, skin surface temperature is elevated by the increased SkBF.

Detailed explanation-3: -However, not taking the right precautions while working out can cause acne to flare, skin infections, and other skin issues. As much as we benefit from those feel-good endorphins, all of that sweat can clog our pores, cause breakouts, chafing, and more.
