Maybe you are nervous about something, or you had a nightmare. Or maybe you are just wearing too much clothes.

Well, there could be varied reasons. One, you are way overdressed or with too many blankets. You can try to minimize these or either open the windows at night. Being too hot can actually make you feel nightmares :) Secondly, you could be having nightmares without. If you have had some problems that bother you more than what you want, they can appear in your dreams. Peacing yourself and remembering it's alright and that it will turn out better are a must for a good sleep. There may be more reasons, but those are the usual ones. Remember that a cool room and an eased mind make wonders in your sleep

That could be a number of various things. I would suggest going to go see a doctor to rule out any medical reasons. Also, consider things that you are going through. Is this something that developed recently? Is this something that you notice occurs at certain times throughout the year? If so, it could be anxiety. Think about if you are anxious or nervous about anything in your life as well.

You may wake up sweating due to the heat in your room. Try turning on the air conditioning so when you wake up, you won't feel sweaty. You may also be dehydrated. Make sure to drink enough water and drink a glass before you sleep. It may also be your diet. It could be anxiety. It could be from weight issues. If this continues for a while and you've tried everything you can, please seek professional medical help.

I've noticed that when I wake up sweating, it can be due to experiencing a nightmare during the night. I might not be aware while I'm having it, but generally when I wake up with a feeling of unease I tend to have sweat quite a bit as well.

Anxiety is something that could be causing it. At night when we are sleeping, our bodies have a lot going on. We carry so much stress with us throughout the day that our body wants to release some of it during the night. Our brains are constantly thinking. One thing that could help, is meditation before bed. It might sound cheesy but its actually really relaxing and it calms your mind before you go off to sleep.

If you're been having nightmares/night terrors, that could be a factor. It could also be hormone related or you might just be too hot.

Sweating in our sleep is not super uncommon, but like with many things the reasons may vary, and ultimately you are the expert on your own experiences. Some reasons might be a high sodium diet as too much salt can push out water from our bodies as our bodies try to metabolize during our sleep, or nightmares that cause your body to trigger a sweat reflex, or it's possible you are legitimately too hot during the night, or it's also possible you have a temporary or long-term condition that causes nightsweats such as persistant withdrawl syndrome. Whatever the case, if sweating in your sleep interferes with your nightly or morning wellbeing, it's totally okay to ask a doctor about it. Good luck!

You could be having night terrors or just a bad dream. Somtimes nervousness and anxiety can stem from this as well

It could be that you're anxious while you're asleep, due to nightmares or stress of some kind. It's also possible that the temperature in your room is too warm.

Maybe you had a hot night or maybe you had a bad dream. Another thing is that maybe you were stressing about something while you slept and you woke up because of that.
November 23rd, 2017 9:18pm
You might wake up sweating due to a bad dream. Probably it's about something you love, care about, or treasure deeply about being harmed.
November 24th, 2017 2:36pm
It might because of your mom or wife who switched off your fan to wake up you.maybe you had been seen any bad dreams..its not a big problem to worry

Sweating can be due to a bad dream, hormonal fluctuations, fevers/chills, flu, too hot under the covers/sheets
January 20th, 2018 6:14pm
When your anxious, scared and frightened about anything that leads to increase heart beat and restlessness which causes sweating

Your body temperature naturally drops to around 60 degrees Fahrenheit while you sleep. Sometimes, if you are overdressed, have too thick of blankets, etc. your body temperature may not be able to drop all the way, resulting in a sweaty, and not very good nights sleep.

Sometimes it can be a medical condition such as thyroid or hormone issues but if you have been cleared by a doctor, you may be experiencing too much stress. Perhaps you can take some time prior to bed to find some peace. Good luck!

If where you are sleeping is hotter than usual body temperature our bodies overheat. to reduce the hotness our body makes us sweat in order to cool us down. Perhaps where your sleeping is to hot.

That’s probabaly because you are nervous about something. People sometimes sweat during their sleep because they’re stressing out.
April 19th, 2018 7:42pm
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.
April 27th, 2018 5:49pm
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.
June 27th, 2018 4:09pm
Could be a lot of reasons: maybe it's too hot to sleep, or you have a bad dream, maybe it's not comfortable
June 27th, 2018 8:53pm
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
June 28th, 2018 4:21pm
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?
July 13th, 2018 10:03pm
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
July 18th, 2018 4:09am
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.
June 29th, 2019 6:31pm
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.

There are many reasons for waking up sweating: You could have too many blankets on or you tend to overheat in the night. If it's none of those, then the issue goes deeper than the surface. One reason could be that you've just awoken from a nightmare, or your dream was intense. If that's the case, it can help to write down your dream in a journal. You can later reflect on it. Even if you don't remember much of your dream, anything is better than nothing. If it's a simple "I woke up sweating.", that's a great start.
