Have you ever heard of a person not sweating enough? My face turns red and stays that way thirty minutes after I get out of the sun. I've had this problem all my life, and people always ask me if I'm alright. I drink only water and lots of it, but is there something else that can be done?
Lack of sweat can be caused by any number of medical conditions. It can also be caused by drugs or damage to the sweat glands. It sounds like you are getting enough fluids which can also be a common cause for this problem. Not sweating enough can cause problems, particularly in hot weather. It is also possible that the redness in your face when being out in the sun is being caused by some other condition. I would check with your health care provider about this just to make sure.
