Why do I wake up sweating?

In my experience it can be for a number of reasons. You may have been eating and drinking late at night, which fuels your body and mind and makes sleeping very uncomfortable. It may be hormonal or you may be developing an illness. It may simply be that there is not enough ventilation in your room.

Your body could be overheated. You could have also had a bad dream which caused your body to go into a panic mode, therefore causing you to sweat.

This can be caused by several things such as temperature, hormones or anxiety. Depending on whats happening when the sweating occurs, your best bet is to go to your doctor to check out what might be going on.

Dreams can be terrifying and beautiful things. When we dream we connect to our subconscious. Our subconscious is the most beautiful and disgusting place in our minds, yet, when we sleep, when we dream, everything becomes connected. That can, however, be more than we bargained for. In sleep there shouldn't be fear, but sometimes there is. Unresolved issues arise when we are at our most vulnerable and sleep is one of the most vulnerable states we have. If sleep becomes impossible, it's a clear sign of psychological issues unresolved.

Sometimes waking up sweating can be directly related to night terrors and or bad dreams that you’re having. You might not be aware of them because you don’t actually remember them, but that doesn’t mean they’re not occurring. Furthermore, it’s common for individuals to suffer from night panic – in which you just wake up in a panic.

Sometimes I wake up sweating because I had an especially bad dream. Sometimes its a sign that my body is out of whack and I might be getting sick. If my body is processing junk food or excess stress I also will have trouble sleeping.

This may happen when you have a bad dream. You wake up sweating because the dream gave you stress causing you to stress sweat.

I wake up sweating after having a nightmare that really terrified me. It made the hairs on my arms stand up and it made me sweat. The nightmare is all I could think about.
