What causes me sweat so much, but only at night?

Question

During the day I sweat, but not much. When the night falls even if it's cool in the house I'm still sweating as if I'm running a marathon.

Night sweats could be a sign that you are sick, please talk to your doctor!

Answer 2

No deodrant? If you do then go to the doctors and get prescription strength

Answer 3

I sweat at night because I have a fast metabolism - if you're thin without dieting, could be why you sweat, too.
