Why do I wake up sweating?

Could be that you are having bad dreams, or something more simple like you're wearing too many covers or are sweating out a fever.

You might have had a dream that increased your respiration and heart rate. It also could be something as simple as you just got hot while you were sleeping.

Could be a lot of reasons: maybe it's too hot to sleep, or you have a bad dream, maybe it's not comfortable

bad dreams or simply excessive perspiration which is quite normal at night. It might be happening due to depression or stressful times. One thing to do to lessen sweating can be sleep with windows open, comfortable thin pyjamas, special bedding that sucks out the sweat and generally keeping a cool and hygienic sleep environment

Nobody knows exactly why but it could be because you are wearing pyjamas that have thick stuff. Don`t worry about it too much.

This could be the beginning of sleep paralysis. Sleep paralysis can cause you to have a restless sleep and can even make you feel as if you can't move. Have you heard of or experienced this?

You could be having nightmares without realizing it. If it isn't intruding in on your sleep and you still feel well-rested it could be harmless. If you do not get a good night's sleep talk to your doctor to get medication

Your room may be too hot when you are sleeping, which can cause you to sweat. A good room temperature to ensure good sleeping is about 65 degrees. :)

These may be signs of secondary hyperhidrosis -- excessive sweating due to medications or a medical condition. Normally, your body sweats to regulate its temperature, and you sweat more during exercise, hot conditions, and stressful situations. You can better know why this is happening to you if you go see a doctor and talk on this.

There could be multiple reasons for this, some people do naturally sweat when they sleep, some people struggle to maintain their temperature when they are sleeping which can cause sweating. Sometimes it can be a reaction to a dream that you are having or if you are not feeling very well. If this is continuous and you are worried you could speak to someone about it and this may make you feel better. If you are seriously concerned then maybe visit a GP or doctor and they can provide you with advice or give you advice of how to combat the issue.
