Why does my body react badly to heat?

Question

Not only does my body react badly to heat, I have Raynaud's syndrome, meaning I have problems with the cold. When I'm out in hot weather or when I have a hot bath or shower I always feel really faint and I have to get out of the heat otherwise I know I'll collapse, sometimes I do collapse. I often black out and forget where I am and always find it hard to control my breathing. What could be causing this?

Check your blood pressure. Go get a doctor checkup.
