Hi, i am curious a to why my body overheats all the time. Im 18 years old, and everytime i get overheated i get really weak and tired. I do not know as to why i overheat, but i do. I can be walking to school n start to get overheated or be sitting on the couch at home and get overheated. Though if im in an already warm environment, i will get even more overheated, weak, tired, along with slight dizzyness. I just to curious as to why this may be happening because it does worry me along with friends and family.
