“Night sweats” refers to the physiological phenomenon of sweating in your sleep. Of course, it is natural to sweat when you are sleeping, but the term refers to excessive amount sweat. After all, your body is at rest, and you are using air conditioning or fans, so what is up with the unwarranted sweatc Though it is not harmful to the body, it can stain your sheets, and also cause a stink when bacteria have the time to digest your sweat. So what are the most common causes for night sweatsc

The first among night sweats causes is dreaming. Dreams are powerful things, and they can cause physiological reactions as if they were real. It is entirely possible to sweat as a result of dreams. If you experience some nightmare, a rip-roaring adventure, or a sexually-charged fantasy, your body can experience the same symptoms as you would if it were real. Your heart pumps faster, your breath gets fast and short, and your body sweats to compensate for the heat produced from energy production in preparation for possible succeeding intense physical activity. You might say “But I don’t dream a lot (or at all)!” You would be wrong. Everyone dreams, and most of us can have a dozen or more dreams overnight. It is just that we forget most if not all of them upon waking.

The second among night sweats causes is the transition into menopause. Of course, this does not apply to men. For women, the hormonal changes that occur during the menopause transition phase can produce intense periods of feelings of heat, which results in the activation of the sweat glands. This is hormonal, and will pass as the transition is completed.

Lastly, night sweats are caused by infections and fevers. You might experience quick fevers that pass in the morning, or you may have some disease that causes you to sweat when you are asleep. Common diseases that cause this are: tuberculosis, HIV infection, endocarditis or inflammation of the valves of the heart, some cancers, obstructive sleep apnea, urinary tract infection, hypoglycemia, and head injuries. In these cases, paying a visit to your doctor may shed some light on your problem.

So there you have it. The three most common night sweats causes, in no particular order, are dreams, menopause, and long-term illnesses. Each can be approached and dealt with in different ways, so there is hope for everyone.



  1. Years of fatigue, excessive hunger, and anxiety anyone else with this problem?
    These symptoms have been ruining my life and preventing me from living normally so please real answers only.

    Years of fatigue, excessive hunger, and anxiety
    These symptoms have been ruining my life and preventing me from living normally so please real answers only.

    For two years now I have been suffering from the following symptoms. Extreme fatigue, anxiety, excessive hunger this all began when I was about 4 months pregnant with my second child. Before that I was not tired during the day or needed a nap. I was able to control my appetite and my weight.
    And I was not anxious all the time and did not have a problem with anger and irritability or depression. But ever since after I gave birth and seen a doctor for the symptoms that seemed quite normal during pregnancy turned into something that looked like depression and I was diagnosed with clinical depression.

    The following is the medication that I have been given and used to help me with the symptoms of that time maybe some depression feelings where there: Zoloft, lexapro and wellbutrin XL

    I was also told I have underactive thyroid and an inflamed thyroid and took Synthyroid for 4 months (side effects from Synthyroid excessive sweating, a bit less hungry) other symptoms where still there so then I saw an endocrinologist who tested for insulin, testosterone levels and THS and said everything looks good its not a thyroid problem or insulin but the testosterone was borderline / high which he said for women my age 26 would be at around 25-50 I was at 76.

    So then put me the birth control yasmin to help bring it down. It has not helped with any of my symptoms. I am still very tired all the time and need to take naps during the day I am always hungry and still really irritable and moody.

    I am a stay at home mom so I do not have the lack of sleep from over working and I do not eat because I am bored I actually feel hungry most of the time. All these symptoms have not been a problem anytime in my teenage years and young adult life until the point of my second pregnancy.

    I am thinking but I am not sure I am not a doctor. that a big possibility for all the other symptoms is the cause from the fatigue and then I eat to trying to give my body sugar to keep going. Which causes me to get moody irritable then anxious and maybe even a bit of depression because of the weight gain and crash dieting.

    Is there anybody who has had these problems and figured out the cause of the problem and been treaded correctly? I just want to get well, be normal, strong and not tired I do not want to feel so helpless and have this uncontrolled hunger anymore. Please anyone with any suggestions or maybe has seen somebody with these problems what did they do to get better?

    Thank you very much for all your help.

    Sorry for the long writing i just did not want to miss anything that could be the difference between the solution and the underling problem.


    • The symptoms you are mentioning would be typical for someone suffering from depression.
      As you told here, all of it started when being pregnant, so the triggering reason for your condition was hormones.

      As you may know (or have realised):
      The symptoms need to be taken care of, what you are experiencing is torture. Common techniques for torturing people use withdrawl of sleep, hunger, pain and anxiety..
      So its only a question of time before you might break and fighting your condition is imperative.

      I would suggest to eliminate any chances for hormone imbalance first.
      Without balanced hormones anything else will fail.
      You might try another pill, or getting off the pill for AT LEAST half a year.

      In addition to that physical exercise (at least 4 times a week for half an hour) and a healthy diet (vegetables and vitamins) will complete the treatment.
      Just dont expect an instant miracle. The condition took some time developing and needs time to “heal” like a physical wound.

      Your best weapon in your fight to get back in control again is perseverance. Pick a date nine months from now and keep up your workout schedule and diet until that day.


  2. Excessive sweating at night due to too much caffeine?
    Hi there. Sorry I just asked this question, but my friend brought up a good point to me. So I find myself waking up in the middle of the night a few times a week due to excessive sweating. I’m 22years old and don’t take meds and I’m healthy as far as I know. But my week consists of 15 hour days. Mon-Fri I work 8AM-5PM, than go to school from 5:30PM until 10:00PM, than I go home and do homework and usually go to sleep at around 12PM-1PM. So because of my hectic weekly schedule I do consume alot of caffeine. Every morning I have a Monster energy drink, and I drink black tea throughout the day while at work. When I get off work, I have another Monster energy drink before I go to school. However there is about a 5-6hour window from my last Monster energy drink until I go to sleep. Yes, I do have a bit of trouble sleeping, but that is usually normal for me. But is it possible that the caffeing causes the night sweats, even though my last dose of caffeine was 5-6hours before sleep time? My friend suggested that it may cause increased heart rate during sleep. Thank you all!


    • That is a lot of caffeine, iDizzle. Try forgetting the energy drink in the morning; take a cool shower. Try backing off the caffeine a bit during the day and see where the tipping point is – how little caffeine can you get by with and still function and be alert. Will your body stay alert on a placebo (decaf or green tea or even just hot water)?
      Once you’ve found the tipping point, back off a little more; if you feel you’re losing concentration while studying, take a 5 minute break to stretch and do some pushups or situps at home, or take a quick walk if you’re elsewhere. Any quick and easy exercise will give you a shot of endorphins to give you the kick you need, and your overall stamina level will improve as you exercise more and ramp your metabolism up.
      Otherwise, check out the link below to see some of the solutions I’ve played with to get rid of night sweats. Hope this helps.
