Question Regarding Child Overheating

Thank you for the articles, they are very interesting, as two of our children had mild rickets-including my little "sweat ball". He sweats constantly, can't take a warm bath or shower. If the water is even a bit warm-he says it's hot. His hair is always wet, from perspiration. One night in TV an actor said that he breaks a sweat peeling an orange--this is how my son is, and he was this way since he was a baby. (he's 13) He has no other symptoms such as being tired etc., the sweat just pours off of him. OUr doctor just told us that this is the way he is. He has no emotional problems, and is not overweight. He plays many sports. If he was very red and had other symptoms, being tired etc. I would get him checked out.
