Excessive Night Sweats

Training
1

I wasn’t really sure where to post this, so here goes.

I’ve had a TempurPedic for about 6 years now, and have noticed a reoccurring issue. Whenever I train, whether it’s lifting or prowler pushes, regardless of the time of day I train, I wake up in the night in a puddle of sweat.

I first noticed it after purchasing the prowler, and doing sprints shortly before bedtime. I naturally assumed it was simply my metabolism being jacked for a while, EPOC. So I dealt with it, whatever, kind of nice to have that kind of proof that torture device does what it claims to.

Now, however, I’ve switched to training first thing in the morning, around 5 or 6 AM, without any late night sprints or anything at all. But it’s still happening. And I’m not sweating through the day. I cool down, feel fine, but go to bed and wake up drenched.

I turned the heat down in my house, to the point I’m cold under the covers. I switched my blanket to a lighter one. I’m sleeping alone so I can’t blame anyone else’s body heat.

And it’s not happening on days I don’t train. I’ve tried eliminating anything I could think of that might be responsible, aside from the bed. I love my bed. But it’s disrupting my sleep cycle and I don’t like it.

Next step, try another bed. But if it still happens, what next? I won’t stop training, but I prefer solid sleep, as well as the recovery it provides.

I’m at a loss, and just curious to see if anyone else has dealt with this. Thanks in advance for your time and consideration.

If it’s happening just when the days you train then it’s probably not the mattress although you could experiment by sleeping on a couch or going to a hotel for a night just to test. If that doesn’t change anything you should get to a Dr. A quick google search suggests it could be a hormonal issue or something like a thyroid problem. Maybe the training sets off the overactivity of the glands which then causes sweats. Nothing to be afraid about but definitely worth having a professional opinion.

Another quick search based on workout supplements that could cause night sweats suggested some pre workout supps cause them, or if you are taking anything with Niacin in it that could do it as well. I only saw one headline that suggested it, but even creatine was mentioned.

Claudan: good one, walked into that.

Pitbull: As a google fan, I cannot believe I didn’t try that first. I feel dumb for wasting your time. Thank you, both good points. I don’t take any pre-workout supps, and quit caffeine recently too. I do take creatine on lifting days, so that’s a variable I hadn’t thought to eliminate. If cutting that out doesn’t help, I’ll follow up with my doctor. Only other supps are fish oil, vit D, and ZMA, all of which I’ve taken for a while, with or without lifting and have no issues.

Dem creatinezz are dangerouzz…

Ha, I wouldn’t say it’s a waste of time to see if others have had similar experiences as someone may have an idea of something that worked for them. I have a hard time believing the Creatine would cause an issue like that as I’m not sure what that would have to do with any of the bodily systems that cause sweating, but I just happened to see it mentioned so I threw it out there. They didn’t teach this diagnostic stuff in my Bachelor’s degree level BroScience classes.

Foam, like the TempurPedic doesn’t breathe well. I’ve heard similar stories by people who just have higher body temperatures in general.

One thing you can do is put a mattress pad/topper over the top of it and under the sheets… doesn’t have to be down; something that uses a polyester filling would work well. That will help dissipate some of the heat, wick moisture away from your body, and cut down on waking up in a pool of sweat.

As far as WHY it happens… it’s because you’re training in the first place. While you’re recovering from the training, both sleeping and resting, there’s a bunch of processes at work that generate heat. That heat has to go somewhere, the body releases water to help cool it down. Most of the time this is just water vapor and not actually water/sweat, but depending on what you’re wearing or sleeping on, it can become wet as the vapor condenses.

I agree with this. Those TempurPedic mattresses trap a lot of heat. I sweat quite a bit from my memory foam mattress pad if my room is warm because it doesn’t breath well enough.

Yeah, the bed is hot, and I’m definitely a warm-blooded person by nature. The polyester top is a good idea. Thanks again, guys.

Agree with Pit on this. If you are training in the early AM and still happening on training days, not the bed. Its medical. Night sweats are usually an early indicator of something else…from personal exp. If its not happening on non-training days you need to get checked out.
