It may be because of heat. It also can be because of stress, a bad dream, or something along those lines

Sometimes things from the past (bad memories ect.) have a way of making it into your dreams and torturing you. Find some way to work around this, like talking to a friend or a therapist.

higher humidity or most probably due to stress full nights. it has happened when your significant other is not satisfying your needs.

Could be lucid dreaming. Your house could be too warm. It could be the type of food you ate before bed. There are many reasons to wake up sweaty from sleeping, but we usually sweat to regulate our body temperature, so it could be environmental reasons.

Sweat is a natural reaction to many things, we sweat when we excersise, when we're too warm, when we're afraid or angry. Your sweating may just be a normal physical reaction your body is giving you, it may simply be too warm, or you could've had a frightful dream, waking up sweating because of that.

Your body is fighting to maintain a constant temperature even while a rep, sweating helps with that

I wake up sweating always that i have the same old dream that made me feel insecure, i´m always in the dark and running as fast as i can but it is never fast enought.

might be possible you had a nightmare. which is very normal. what i would suggest is before going to bed try thinking about happy thoughts.

Moving around a lot on your sleep or maybe you wear too much clothes when sleeping or you duvet is too thick :)

You wake up sweating, maybe due to your body overheating while you sleep, so your body will sweat to cool you down.

Maybe you had a nightmare or something in that context. Or maybe you move quite a bit in your sleep.

When I wake up sweating it's from a bad dream or memory I had or you could be really scared of something
November 28th, 2015 10:32pm
That's probably because your brain was working really hard to process your underlying thoughts of the day

I haven't woken up sweating in a long time. In the past, it was because the a/c wasn't set cold enough. Now, during warm months I sleep with a fan pointed at the bed.

Well it could be stress, it could be just to warm at night. Try a fab or a lighter blanket. Having a window open helps also.

maybe you are haveing bad dreams most dreams you forget about so you might not rember the dream but you still wake up in sweat

You may have just experienced a bad dream that could have caused some anxiety OR your body could be temperature sensitive.

I woke up sweating once because i had a bad dream... probably because i worried to the max. I cried soon after waking up. It's good that I have a hobby that keeps my mind off my problems, because without it I'm sure I'd wake up sweating every morning.

Try to check proper ventilation ; the sheets you are using ;and the routine you had been doing everyday; otherwise consult doctor

I might just had a bad dream, and got pretty anxious about what happened inside the dream, like running away from someone or etc.

Waking up sweating can be a sign that you have had a nightmare, been anxious or panicky in your sleep or you overheated whilst sleeping, although if it is a recurring incident then consult your doctor as it could be a medical issue but a one off or once a week sort of thing is probably nothing to worry about

I wake up sweating when I have a bad dream, I suffer from extremely realistic and vivid nightmares on a daily bases. Whenever this happens I wake up in a terrible sweat.
October 5th, 2016 11:44pm
There could be several reasons... Might be it was such a hot day or ur air con was not on or you could be worrying about something and anxiety makes you nervous and sweat.. so you probably might not be sleeping well..

Excessive sweating is called Hyperhidrosis. Night sweats can be from different number of things. Night terrors, sleep disorders, medications, or medical conditions. See your doctor if it's a bother to you.
October 23rd, 2016 5:40pm
this can be due to a number of reasons, if this is due to a panic attack and occuring on a regular basis then medical assistance should be given.

This can be for many reasons. Do you have bad dreams? Do you struggle to go to sleep? Is this a recent event in your life? Has something else happened in your life that coincided with this? These can be some routes to an answer.

Firstly, look at your physical environment. Is your bedroom too hot, or do you have thick pyjamas or a thick duvet on your bed? Sometimes people do wake up sweaty, and it's just a normal thing to do! If your sweating is excessive, and your environment doesn't offer any clues, maybe check in with your doctor? Another explanation could be that you have had a nightmare or unpleasant dream that you don't remember, and the sweating is simply your body's response to a perceived threat.

I can only answer for myself, but I used to think that was normal. I thought everyone woke up in a hot flash. It turned out that it was because I had sleep apnea. I didn't get tested for it because of the sweating, but I did notice that they stopped after I was able to use my bi-PAP, and I notice that I wake up hot if I forget to put it on. There may be different reasons for you, but that was mine.

Sweating is normal under the nights, because the body relieves unnecessary particles from our skin. Sweating can also be a side-effect of many medicines like antidepressants. If this problem bothers you constantly, I advice you to talk with a doctor.
