Hi, my boyfriend is a regular health male, he s 20 and active. He complains of being excessively warm all the time. We can be sitting in the same room, he ll be burning up and i ll be a bit chilly. If we re walking up a large hill or playing a sport together, i ll just barely be breaking a sweat and he ll be drenched in sweat. He used to work out a lot doing pull-ups and such but not as often anymore. He s not overweight, he s 5 8 and 155lbs. I m wondering what could cause him to be so warm all the time. He s always watching his health and taking good care of himself but i m really clueless what this could be. Any ideas?
