During Sleep My Body Temperature Rise to the 100's (Page 13)


March 23rd, 2014
52 yr old male German background always been a night time furnace. Wife says I like a baked potatoe. Ive always slept naked with usually just a bed sheet, no sweating at night or limited during excersise even heavy cardio. I take no meds of any kind and my diet is stellar - GF DF and very low sugar. I have had some issues with blood sugar in that Im a "high protein type" keep nuts in the car, if I don't eat smallish regular meals ( 3 per day with 2 heavy snacks) I get kind of light headed. Ive wondered for years what could cause this, usually starts 20-30 minutes after i lay down I just start heating up I always think of an old STeve Miller song Abracadabra "I heat up, I can't cool down" lol. Not a big issue for me because I don't think my core temp raises or my BP i have traditionally low BP so symptomatically Im a bit of an anomaly. Lastly I work out heavily 3-4 times per week very good physical shape so Im not sure health wise I could be any better.

Incidentally I have a friend who I coached hockey with recently pass away of heart attack at 46. We were talking about beds whats better best etc and he disclosed that he had night sweats so bad his wife had to do bed linen DAILY. Anyway at the time I thought DANG that is definitely not normal wonder if he ever had his heart checked?
So I think its possible he had a birth defect in his heart from birth but Im only speculating and grateful I never had to deal with night sweats

What happens to your body while you're asleep


At sleep onset, core body temperature falls but peripheral skin temperature rises. But temperature changes become more complex during sleep as our temperature self-regulation varies according to sleep stage.

Research has shown how environmental heat can disturb this delicate balance between sleep and body temperature. An ambient temperature of 22 or 23 Celsius is ideal. Any major variation in this leads to disturbance of sleep with reduced slow wave sleep (a stage of sleep where the brain’s electrical wave activity slows and the brain “rests”), and also results in less dreaming sleep (rapid eye movement or REM sleep).

Indeed during REM sleep, our ability to regulate body temperature is impaired so in a clever sort of way the body “avoids” this stage of sleep during extreme cold or heat. A heat wave may cause several nights of fragmented sleep with less slow wave and REM sleep. This will certainly cause a correct perception of bad, restless sleep with consequent negative effects on mood and alertness.

In theory, it may also have subtle effects such as problems with complex memory retention, higher judgement (poorer decision making and increased risk-taking behaviour), blood pressure control and regulation of glucose in the body. The clear message is this: if you’re going to make some big decisions during a heatwave, sleep in a carefully controlled air-conditioned environment.

But apart from air-conditioning, what can you do to sleep better during a heatwave? Sleeping in the lateral position (on your side) with less contact with the mattress may be good but the body tends to do this anyway during sleep, in response to rising temperatures.

Cooling the central body with a wet cloth or towel makes sense. A cool shower may also help. It is important to avoid doing anything too strenuous in the hours before bed-time as this will make it harder for the body temperature to fall during sleep.

During deep sleep, the skin's metabolic rate speeds up and many of the body's cells show increased production and reduced breakdown of proteins.

Since proteins are the building blocks needed for cell growth and for the repair of damage from factors like ultraviolet rays, deep sleep may indeed be beauty sleep.

Daytime sleep will not compensate for loss of nightly 'beauty sleep' as the energy needed for tissue repair is not available during daylight because it is being used elsewhere.

I have not read all the comments, but I would like to chime in on this because it is a result of a serious underlying issue. I work in a sleep study lab and we see this issue all the time. I will try to keep the explination short and simple. First of all the phenomenon is known as Bio-Thermokinesis. To explain it is very detailed, but basically it's a Fight or Flight response, some people have learned to manipulate this response and control thermal responses in the body. The more important thing here is the cause. BTK usually happens during episodes of sleep apnea (failure to breath during sleep) basically people that experience this, will have a sudden drop in body temperature because of severe loss of circulation, your body kicks into survival mode and heats your body trying to increase circulation. When you wake your circulation will return to normal, and your body temp will return to normal, but it will leave your skin feeling warm, somtimes resulting in cold sweats ( your core temp is lower then skin temp, you prespire to lower skin temp, but it also lowers core temp. Leaving you feeling cold but still sweating. another cause is directly related to sleep apnea in many cases. It is signs of heart disease (again same issue slow circulation) . This usually happens when there is valve issues, and usually manifests at a critical points. Typically a person will have an injection fractions

I have this problem too however it has only started to happen recently. I am 29 year old male with no known health issues. over the past few weeks my tempreture at night rises greatly but i dont sweat? my partner says im so hot that she cant even touch me at night. dont know if related but i often grind my teeth at night and can sonetimes be quite fidgety/move alot during sleep. from what ive seen on the internet so far i think this may be related to anxiety and stress.

I too have this problem, and I am 14 Native American. I live in Michigan, and in the winter I sleep only with a sheet and I still get too hot. I have found that putting an ice pack behind my knees helps to cool me down. However, it is hard to stay asleep because I wake up from being so hot.

I've always had this even since I was little. I had an ex once that tried to freeze me to death every night. Not really he just slept with a fan on high all night, because I was too hot. I've been through sleep studies. My case has nothing to do with sleep apnea or poor circulation. They couldn't pinpoint what caused it though.

Fire Back
I get so hot when I am in REM sleep stage that I think I am on fire but really I am not. Anyone else have this experience? Maybe it is imagined fire? I don't know, do you?

My baby has always had an increased body temperature when he sleeps but now as a toddler it gets so high that it awakens him sometimes. His temperature raises over 101 [email protected] night while sleeping & I keep our room very cool, around 68 @night. He can't wear PJs anymore cuz he will get too hot so now he go's to bed in just a tank top & pullup. His father, African American, had a higher temperature while sleeping also. It worries me because he gets so hot it wakes him from his sleep. He wakes up & gets in bed with me and his skin is so warm. Then he sweats by morning when it comes down. Does anyone have any information on why he does this. Normal body thermoregulation causes your temperature to drop while sleeping. Why doesn't his?

My skin gets very hot to the touch when I sleep also. I am of Lebanese descent, my father is Lebanese, my mother is not. I feel somewhat warm when I'm sleeping but remain under the covers because I also get cold very easily. I live in south Texas and do not enjoy any temps below about 80 degrees. I keep a jacket in my car so that its with me wherever I go because most indoor temperatures are too cold for me. My husband tells me that my skin nearly burns him at night. What's the issue? This has happened to me for as long as I can remember. I am overall in good health. I'm genetically small framed. I do not exercise but am not overweight. I'm 5'3" and weigh 120. Has anyone solved this mystery? I'd love to know why this happens. There is no snuggling going on in my bed! Wink

My sleep Doctor mentioned upper airway resistance syndrome. Might be worth looking into. It sometimes causes a rise in body temperature, frequent trips to the bathroom, grinding of teeth etc

I've often woke up with burn marks across my cheek bones where my VPAP straps are located when wearing my mask. I have sleep apnea and I'm not sure what is causing our temps to rise so high while we sleep but KodiakJay above seems to be,the closest in making sense of it all. But one more factor to consider to is I am RH- (B-) to be exact) and have difficulty maintaining my iron levels. It seems that when my iron is low, I wake up more often with the burns on my face (mid you my temperature rises so high that the rubber on the strap touching my face literally becomes so hot, it blisters my face and takes almost two weeks to go away. But when my iron gets higher, my sweats seem to be less; either that or I'm just hoping that's the cause.
I'm open to any other ideas but so glad I'm not the only one who has thought of human combustion. Thank God for the Internet! Hope others might consider it their iron as well! What a relief that would be! God Bless Us Hotties!

My Husband has the same issue it started about a year ago. On the way to falling into REM his body has jerks. Hands will jerk as if he's fighting someone or feet and lower legs move in a kicking matter and in those nights during the early morning hours he will radiate so much heat. If I wake him he says he is sweating. I was told by mom that issues like this is heart related. Maybe blockage. I believe we need to do a stress test. He also has high BP and is on Losartan. Maybe this is a way of the body telling us something. During the day I forget about this and remember around 4 am when it's happening. This is my 2 cents. I'll write an update to what we find.

So I am between 4-9 years later on this post but I thought might be able to help some people out. First off if you have night sweats that's a whole different problem and has do with you not entering REM sleep. In REM sleep you cannot sweat or shiver it's impossible. So it means you aren't really sleeping for some reason such as stress, anxiety, etc. However if you are waking up hot or your partner is telling you that you are warm during sleep thats another issue. Some people mentioned that your temperature is supposed to lower during sleep. That's not exactly true your she'll temperature should lower core should stay the same and your brain should increase more so then when awake. Your body has to regulate temperature without its normal arsenal of sweats and shivers. The best outlet for excess heat is your feet and hands. I would try making sure your not wearing socks and that feet and hands are not under the blankets. If you are the partner sleeping next to an oven uncover their feet. If this doesn't work it could be a problem with your hypothalamus not correctly detecting your core temperature and causing you to bleed off heat through you skin. Another issue could be poor circulation, cigarettes are bad for you. Since your blood isn't moving fast enough it isn't cooling down and your body is releasing the heat through your skin. When you are up and moving around your heart beats faster speeding up your blood relieving the heat. This can be helped by drinking more water to thin your blood, quitting smoking to increase circulation, or having a doctor prescribe a blood thinner. On a personal note if you buy a memory foam mattress get the cooling kind. I had one of the early ones and it just trapped all the heat not allowing any airflow or wicking of temperature. And also a warning if your extremities as mentioned in the post above are turning blue you have serious circulation problem or frostbite and should seek medical attention immediately.

I am a Healer with the gift of "Laying of the hands"
Most call reiki I have gifts from extraterrestrial the whole point of my reply is because the more I have been healing with my hands which is heat coming out my hands I have totally realized the heat I have been producing all over my body at night in bed is a protection field
Protecting my aura I have had several partners who later I found out they were not sincere and the heat pushes them out of my bed which is always a good thing that's my situation. In any case I most definetly know for a fact most of the people with this case should know they are healers that should know that they should be working as light workers !
Hope this Helps
