I've had this problem for a while, but I'm sick of it and it's cramping my style.
When I exercise and get hot, my face turns BEET red and it does not sweat. My neck is sweating, my back, chest, etc. but not my face. It happens mostly in warm weather (60 degress or above). I couldn't finish my usual run today because I was just too uncomfortably hot.
I read somewhere that it's the blood or blood vessels coming to the surface of the skin, trying to cool me off, but it isn't working! I will not be able to run outdoors again until it cools off if I can't figure this out.
Does anyone know why my face won't sweat??
