Night Sweating?

Question: I have never really done cardio in the past but about two weeks ago I started. I had finished the V Diet and lost around 16 pounds. A few weeks later I started running. Well, I was 239 before diet, lost 16 pounds to 223. Since starting running 2 weeks ago I havve list another 10 pounds and am down to 213 now. I am also sweating like a 2 dollar whore on welfare check day when I am asleep. I wake up to a soaking wet bed and pillow and it is disrupting my sleep. This is happening every night. Have any of you experienced this? The weight loss and sweating are both things I am not thrilled at all about. I am comfortable at the 225 + weight.

I also experience this, but I live in Texas so I never saw sweating as a big deal. Where do you sweat the most? I usually sweat around the neck and shoulders area. I have found that other areas of life tend to play a bigger role in this, namely stress. I am intrigued what other t-members have to say about this.

Odd, my girlfriend just pointed this out to me about two nights ago. We’ve been sharing a bed for over a year now and it’s only recently that I’ve begun sweating so much. I haven’t been doing cardio at all though. I think it’s because I’ve finally started eating enough. Have you been upping the food intake to match your cardio?

Molon Labe!


Yes, my head and shoulder area are the areas that are wet when I wake. I have the AC on 70 and I wake up dripping. I have had it happen in the past but this was normally when I was fighting off the flu or somethng, not a nightly thing.

Just speculating, but it may have to do with the fact that your body temperature is elevated by cardio or a fever. I noticed this to really affect me after intense cardio. Maybe the fact that our bodies have adapted to intense work may come into play. If you notice that after you swim laps (if you do) the surface of your skin will tend to feel warmer to the touch for a short while after this. I use swimming as an example because the surface of your skin is cool when you exit the water. This concept may have some carryover into your sleep. Your body might maintain that elevated temperature for a long time. Why it concentrates on my neck and shoulders baffles me. I am neither in the medical field nor a swimmer. This is just what I have noticed. Like I say, I am just speculating. Nice analogy BTW. :slight_smile:

No, to be honest my food intake has sucked since I got off the V Diet. I just cant seem to get back in the swing of things. The V Diet really screwed me up. I wanted to lose a little fat and ended up losing 25 pounds. I am working at getting my diet back in check so I can blow up again but continue cardio so I dont put so much fat on. I was at about 24% BF and am now down to 13%. If I can stay at 13% and get back up to around 225 I will be happy. My strength had drastically gone down as well which is expected with a 25 pound weight loss.

night sweats…I get them on and off. Sometimes it’s so bad I need to throw a towel on my bed and another on a new pillow. I have no idea why.

I only seem to get them when I drink a few glasses of wine. Never had them with beer or anything else for that matter.

Add me to the night sweat camp. Relatively new thing, last 2 years or so. Am 31 now so maybe age plays a part, I don’t know. But it is not constant, comes and goes, but can last for several days / weeks at a time. I just plain soak my bed / pillow etc. I live in Seattle WA and will sleep with my window open, so it isn’t that my apartment is too hot, or too cold. Nor do the sweats really feel like they are associated with an outside temp, if that makes any sense. Definitely leaves me with a restless, poor night sleep.

I do hate it though, just kind of gross and a pain in the butt. Especially when you have a new girl sleeping next to ya.

Would love it if we could figure this out. Anyone else with a similar story?

I am allergic to almost everything,and have had cancer ,before my cancer surgery i used to get the night sweats a lot,after my surgery it has almost stopped ,just once in a great while nowadays.

Sounds like an epidemic has started. I am going to have to quaratine all you fuckers or maybe you should turn the water beds down.

8 Causes of Night Sweats

Medical Author: Melissa Conrad St?ppler, MD

Doctors in primary care fields often hear their patients complain of night sweats. Night sweats refer to any excess sweating occurring during the night. However, if your bedroom is unusually hot or you are using too many bedclothes, you may begin to sweat during sleep–and this is normal. In order to distinguish night sweats that arise from medical causes from those that occur because one?s surroundings are too warm, doctors generally refer to true night sweats as severe hot flashes occurring at night that can drench sleepwear and sheets, which are not related to an overheated environment.

In one study of 2267 patients visiting a primary care physician, 41% reported experiencing night sweats during the previous month, so the perception of excessive sweating at night is fairly common. It is important to note that flushing (a warmth and redness of the face or trunk) may also be hard to distinguish from true night sweats.

There are many different causes of night sweats. To determine what is causing night sweats in a particular individual, a doctor must obtain a detailed medical history and order tests to decide if an underlying medical condition is responsible for the night sweats. Some of the known conditions that can cause night sweats are:

Menopause ? The hot flashes that accompany the menopausal transition can occur at night and cause sweating. This is a very common cause of night sweats in perimenopausal women.

Idiopathic hyperhidrosis ? Idiopathic hyperhidrosis is a condition in which the body chronically produces too much sweat without any identifiable medical cause.

Infections ? Classically, tuberculosis is the infection most commonly associated with night sweats. However, bacterial infections, such as endocarditis (inflammation of the heart valves), osteomyelitis (inflammation within the bones), and abscesses all may result in night sweats. Night sweats are also a symptom of AIDS virus (HIV) infection.

Cancers ? Night sweats are an early symptom of some cancers. The most common type of cancer associated with night sweats is lymphoma. However, people who have an undiagnosed cancer frequently have other symptoms as well, such as unexplained weight loss and fevers.

Medications ? Taking certain medications can lead to night sweats. In cases without other physical symptoms or signs of tumor or infection, medications are often determined to be the cause of night sweats. Antidepressant medications are a common type of medication that can lead to night sweats. All types of antidepressants can cause night sweats as a side effect, with a range in incidence from 8 to 22% of persons taking antidepressant drugs. Other psychiatric drugs have also been associated with night sweats. Medicines taken to lower fever such as aspirin and acetaminophen can sometimes lead to sweating. Other types of drugs can cause flushing, which, as mentioned above, may be confused with night sweats. Some of the many drugs that can cause flushing include:
niacin (taken in the higher doses used for lipid disorders),
nitroglycerine, and
sildenafil (Viagra).

Many other drugs not mentioned above, including cortisone medications such as prednisone and prednisolone, may also be associated with flushing or night sweats.

Hypoglycemia ? Sometimes low blood glucose can cause sweating. People who are taking insulin or oral anti-diabetic medications may experience hypoglycemia at night that is accompanied by sweating.

Hormone disorders - Sweating or flushing can be seen with several hormone disorders, including pheochromocytoma, carcinoid syndrome, and hyperthyroidism.

Neurologic conditions ? Uncommonly, neurologic conditions including autonomic dysreflexia, post-traumatic syringomyelia, stroke, and autonomic neuropathy may cause increased sweating and possibly lead to night sweats.

That’s weird. I only sweat when I don’t wear my pj’s. It’s crazy. If I go to bed naked or without a t-shirt I immediately start sweating like a pig but as soon as I put on my pj’s it all goes away.

And this has only started about two years ago when I started using anything to sleep in. Had always slept in boxers before that.

I’m 27 and 6 foot 218 lbs. But I think mine is from BJJ and the fact that I’m doing an insane amount of work when training with a full heavy GI on. I tell my girlfriend and myself that my body has probably gotten so good at regulating my temperature with the GI on that wihout it, it overheats.

I used to have night sweat, and after some experiencing, I found out it came to be when I was on a low-carb diet. I tried uping the carbs on my last meal and the NS diminished…

And it works everytime, at least for me. Since you’re dieting yourself, I thought it might be the same phenomenon. Anybody else can relate night sweating with diet?

if i lift after work i will definitely be hot that night. especially w/ squats and deads, so i do my best to get those workouts done in the morning. incidentally, i feel i recover faster from really heavy workouts if i do them in the morning.i’ll bet it’s cause i get alot more food in all day whereas at night i only get dinner and pf bedtime meal before the 9 hr fast.

anyway back to bed …down definitely doesn’t breath enough for me and makes me sweat. same with high thread count sheets - like 450 and higher. 100% cotton is a given. i have some 700 count sheets that i can’t even use in the winter, and i like my bedroom @ 55 degrees(warning:girls do not like this).

anyway i stuck the down in the closet and went to wool with 250-300 sheets and it’s all good.

I think what we can take away from RockScar’s post is that you guys are having hot flashes.

Ha, I had one so bad last week when I had the flu I had to do the same thing.

This would be me. I’m going on about 15 years of it. There is nothing wrong with me medically. I tend to think its somehow hereditary too (my mom, sister, brother, cousin all experience it).

At this point the curiosity is killing me - WTF would cause this? I’m not talking a little hot around the collar either. Getting out of bed & seeing a definate wet imprint of my body on the bed, beads of sweat sitting on top of my feet, changing bed clothes 3 times before midnight. Surprisingly alcohol consumption can actually stop it for me.

During this 15 years of it, it has actually disappeared for periods of time for no reason & return for no reason. A true Scooby Doo mystery.
