Waking up overnight DRENCHED in sweat

Posting here in case anyone else has had this and knows what it is!

ive been struggling with really bad night sweats recently. All my life I’ve naturally been a cold person but for a few months now I’ve been feeling absolutely boiling hot at night. It usually starts about midnight or so, feels like I’m unbelievably hot and the sweat literally soaks my pjs and bedsheets and I’m dripping wet with it. If I’m up late then I’ll feel it start but if I’m in bed early then it’ll wake me up during the night when it starts . I’ve tried light bedding, no bedding, light pjs, no pjs, windows open (my bed is literally right beside it). I live in northern Scotland where it’s been baltic recently and my car is iced up every morning but I’m still waking up roasting. Heating thermostat is set to 15 overnight but I’ve tried even lower and it makes no difference. My room isn’t particularly warm or a heat trap, I’ve never had this issue before and I’m completely fine during the day. Does anyone know wtf this is and what I can do to stop it? Frankly I’m fed up having to wash my hair in the morning because it’s wet with sweat from during the night

i went to the gp who checked my thyroid and hormones and it was all normal. I even went privately for amother full hormone check so I could make sure the levels were normal and they were all completely fine. I’ve had a few full blood tests recently (for a completely separate thing) and I remember on once instance the doctor said my white blood cells were high, I think it was 15.5? Then another doctor said whilst it’s high it doesn’t matter because they’ve seen that for me in my other recent blood tests so that’s normal for me. Otherwise it was all fine

I’m just at a loss for what it is! I’m not menopausal, I’m 28, female, I’m not stressed, I exercise regularly and don’t drink or take drugs. Just at a bit of a loss! The doctor said not to worry about it and it’s just one of those things but it’s having a big impact on me

Drenching night sweats were the main symptom of my Dad’s leukaemia. I have night sweats but I’m peri menopausal. None of us want to scare the OP but we are sharing our personal experiences of night sweats as requested.

OP, you have symptoms for which your doctor hasn’t yet given a diagnosis. I sincerely hope that it’s not anything serious but you need to advocate for yourself and request further investigation. If he/she won’t, request to be seen by a different doctor. x

Well the things that people are suggesting are scary, there's no way around that. OP is asking so it's OK to raise them, I'm just not sure that prefacing with not wishing to alarm or scare makes it easier to read.

How can your post NOT cause alarm?

Covid jabs….when I had the second one I sweat profusely.

Edited

Sorry I hope I don’t come across dismissive but I don’t believe for me it’s the Covid jag which caused this x

Not to alarm you but as someone else mentioned it could be a sign of leukaemia. This was one of the symptoms of my partner and we had no idea what was causing it till he went to the GP…

thanks everyone for the advice!

in all honesty, I don’t think it’s early menopause. I guess it could be but it just seems really unlikely with my age and the fact my hormone tests were fine

the lump is a really weird one and I never really got any clarity of what it is. They just said it’s normal for there to be asymmetry, but didn’t say why it would have suddenly started. I definitely didn’t have it before. But the x ray was fine and didn’t pick up any abnormalities. It hasn’t grown over the last year and if it were anything bad, would it likely have grown much bigger? I’ll attach a picture of it below

im going to go back and request another blood test or even go privately. I know serious things are rare but id like to get it double checked because I don’t know why these symptoms are happening

thats really interesting about cheese causing it for some people! I actually don’t eat cheese but that’s a funny one! I’m not sure its diet related either- I haven’t changed anything, eat healthily and have no allergies

it’s such a strange one but hopefully I’ll find it what’s causing it soon because it’s driving me mad x

15.5 is high, mine was 16 when I had lymphoma. I'd ask for another blood test and if it's still high get referred to a haematologist for further investigation. Sending hugs either way!

EmeraldShamrock000 · 09/03/2026 18:57

It happens me randomly every 5 years or so, no
meno yet. I personally love it as I’m always freezing. It’s a thrill to feel so hot. I doubt I’ll feel the same about full on menopause.

WateringCans · 07/03/2026 09:51

I had similar and it was because I had a cheeseboard left over from a party, so was eating a lot of cheese. I had been going to bed wrapped in a sheet with no pyjamas, so that when I woke up freezing cold and soaking wet, I could take off the sheet and put on dry pyjamas. Even my shins were sweaty 🤮

it didn’t start immediately - as in, I had had a couple of cheese evenings with no trouble, but as soon as I stopped the cheese the sweats stopped. And it’s never happened since.

How strange! I'm the same, soaking wet and freezing cold.. I am a very cheesy person but always have been 🤣

Op same thing happend to me at age 30. Went from being a person who wore thick heavy pjs and an extra blanket to a night sweater almost over night. At the time I was worried about early menopause and got tested. Negative. Went on to have 3 children , last one when I was 45! I never discovered the reason for this but since then I have had to sleep naked and have night sweats. I am perfectly healthy.

whn I have researched it some people just have different hormonal changes at night.

YoureOnTheRightTrack · 07/03/2026 08:52

Please go to another Dr and ask for further testing, a CT ideally to rule out Lymphoma. It can be slow growing and asymptomatic for years and doesn't show up on blood tests in most cases. But elevated white cells and drenching night sweats are classic signs. The others to look out for are fatigue that sleep doesn’t eleviate, unexplained weight loss (or gain in my case), itching skin without an obvious reason, bruising more easily than usual, and several others.

In my case they suspect I had it for years before presenting with more serious symptoms that meant it got picked up.
It very probably isn’t this, but its not unheard of at your age and is something much more easily treated if you catch it earlier, and I know several fellow Lymphoma or Leukaemia sufferers who were fobbed off for years before being taken seriously. Often the only way to diagnose is through CT scans or biopsy.

PieLoe · 07/03/2026 07:36

I’ve had them since age 21. But not as bad as you OP. Autoimmune or arthritis? Never got to the bottom of it!
I hope you get some answers.

Yeah had my thyroid checked and it was fine. I was sure it would be something like that, or something hormonal, but it all came back well within normal.

I know a few folk have mentioned getting something serious like lymphoma ruled out- does anyone know how I would request that or do that? I was told that the white blood cell thing is only a little raised at 15.5 and if it were anything serious it would be much higher, and they told me the lump is fine on the x ray and with where it is it’s not a lymph node anyway (it’s literally right on my sternum/clavicle and it’s more boney) so they said that’s unrelated, and they said the extra periods are unrelated and just one of those things that sometimes happens and the fact my hormones are fine means there’s nothing wrong. Just not sure what I should be requesting or pushing for or the best way to get lymphoma specifically checked for? I don’t think it’s anything serious like that but I want to follow everyone’s advice and get it ruled out x

If your lymphocytes are higher than normal range then you need a flow cytometry to check for leukaemia/lymphoma.
The blood will be sent to a specialist laboratory.

mjf981 · 07/03/2026 06:44

Can you feel any enlarged lymph nodes?
I know it's been said a few times, but my friend had this and was diagnosed with lymphoma. The first symptoms was night sweats, then she noticed some enlarged lymph nodes in a her groin a few months later.
Hopefully not, but I'd want it ruled out.

Mmmm19 · 07/03/2026 01:03

Agree it should be investigated
im medical and didn’t fully understand what ‘drenching’ night sweats from the red flag text books were until I had them myself. Mine turned out to be a weird post covid thing but my gp did bloods and a chest xray as first step of investigations

I'm diabetic and get horrendous night sweats if my blood sugar drops during the night. Have you asked your GP to check your HbA1C?

Came on to say the same, I have terrible night sweats when my sugars go below 3 in the night, wake up feeling very jittery too. You used to be able to get a blood sugar reading at the chemist, I'd fast for 12hrs then get one done

Arregaithel · 07/03/2026 00:31

@cinnamonrolls3 do not be fobbed off, what you're experiencing necessitates further investigation

Agree with @DisappearingGirl, hodgkin lymphoma can present with the symptoms you describe

springawakeningss · 07/03/2026 00:10

I'm the same except my night sweats in not hot, I wake up drenched and freezing cold! Anyone have any ideas??

Moveyourbleedingarse · 06/03/2026 23:57

OP, you are young so I assume you have the NHS app.

Have you looked at the actual blood markers and The ranges and checked them yourself? You shouldn't have to but often on here people find our that they are actually out of range when a GP has said they are in range.

Anotherdayanotherscan · 06/03/2026 23:50

The raised WBC suggests some sort of inflammatory process. Do you have hx of Ibd or bowel issues? Have you checked your boobs for lumps, just in case, this is one sign in breast cancer although very unlikely.

Would chase GP about the hormonal period stuff, do you have a GUM clinic that you can self refer to? Might be quicker depending on how useful your gp is.

Any other medications?

Op is 28...hardly likely to be this Hmm

I knew someone who went through the menopause at 29. It happens.

womblemum · 06/03/2026 23:29

I had a couple of bouts of night sweats in my late 30s / early 40s and I think it was a combination of cyclical hormone fluctuations and stress (wasn’t peri-menopause). However, night sweats were the first and only real symptom of my Dad’s non Hodgkins Lymphoma so should you should get checked - not least because the stress of wondering what the cause is could be prolonging them. There was a blood marker that prompted my Dad’s speedy referral. I can’t remember what it was, but it wasn’t white blood count.

Diabetes can give you night sweats.
