when you are sweaty you are usually excersizing so ur heart rate goes up and more blood is going faster to your body turning ur cheeks red
um, im not sure actually, but i think its because when you sweat, you open glands, which cauzes redness.
only white people blush.
Some people have more blood vessels close to the skin surface. When they feel hot and perspire, the blood vessels dilate thus the skin turns pink.
This is more observable in light-skinned people.
As your heart races, more blood is pumped in your veins and arteries and that’s why any light skin person will start turning red and blush.
Exercise will cause you to become red in the face or Flushed. If you have never Blushed then you haven’t been in Texas.
