So I have been working out a little (jk I was just running a mile) and I noticed that every time I work out, I get red and it stays like that for a while! Why does that happen?

Explanation:

Why do I turn red when I exercise?

When you exercise, your body temperature increases and carries the blood towards the skin's surface, causing one to sweat and cool off. This natural body mechanism can lead to a flushed, red face, which can be especially more noticeable in fair-skinned individuals.
