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

Peri-menopausal night sweats.

This. 100%

When I went to the drs with a lump in my neck (it wasn't it was a muscle) the first thing the GP said was are you having night sweats.

drusilla49 · 05/03/2026 19:43

I too would be asking my GP to rule out more sinister things such as lymphoma. Night sweats are a huge red flag symptom. They should be looking at more than hormones.

I'd go back to GP as I'd be worried about the bleed between periods etc as could be ovarian cysts or similar or early perimenopausal symptoms.

My experience of night sweats is perimenopause related but that started at 40yrs old.

Could you be pregnant?

definitely not pregnant x

Allergy. I am allergic to sulphites in wine. If I have a glass of wine in the evening then I would have severe night sweats. Even half a glass would do it. Other foods trigger it to a certain extent but I haven’t pinned down which.
Instant coffee can trigger it. I rarely drink alcohol and stick to fresh ground coffee. I also try to eat as little ultra processed foods as possible that may contain preservatives.
Some foods are estrogen mimickers may be worth doing a bit of research. Some of us are estrogen sensitive.
Do you have a heart murmur? Endocarditis can present with night sweats.

Any weight changes? With a high white cell count I’d want further testing to rule out more serious conditions like lymphoma.

This worried me as exactly same symptoms as my mum when she had lymphoma

NinaNina83 · 05/03/2026 18:20

Anything caught early is more treatable than when it’s realised later on. The sooner you have more testing done the better.

One symptom of kidney cancer is night sweats. It’s a type of cancer often not easily spotted because there are so few symptoms. Night sweats can be a symptom though so I would want more tastings

Agree with this. I had lymphoma and would wake up absolutely drenched. I Would have to change not only my nightwear but the sheets too and eventually started lying on towels. It’s a very different experience to a hormonal sweat, this is like when you are ill with a horrible virus.

ThatPearlkitty · 05/03/2026 18:17

on occasion in the past yes

28 isn't too young. Plus so-called 'peri' can last for years with different symptoms coming and going. I had a few instances of night sweats at least 10 years ago and I'm still not in menopause.

How do you know it was perimenopause related then?

VictorianScreenTime · 05/03/2026 18:14

Sorry if I missed this but did you have a vitamin b12 level checked? It’s somewhat routine but not always done so just worth checking the list you had done. Low B12 can cause sweats.

No not every night but happening more regularly. I’d say it started a few months ago but was infrequent at the start and it’s happening a lot more often now. Probably most nights a week now

i initially thought it was hormone related because I had a different weird symptom (I had bleeding in between my period, not like slight spotting, like proper bleeding) but that was a few months ago. I’ve had slight spotting since and then today funnily enough had another period despite it finishing last week so definitely not due. That was new when it started a few months ago and not something I’d ever had bother with before and made me wonder about hormones but they checked me and I was fine. I don’t get any pain or cramps with it, it’s just extra bleeding, they said sometimes it just happens and they don’t always know why. They said it’s unrelated to the night sweats because my hormones etc are all fine but that’s what initially prompted me to request a hormone test

I don’t have any children, never had malaria, I’m healthy weight, no changes in lifestyle/diet/exercise regimes, I’m not on any medication either

it’s so bizarre but I wish I knew how to stop it. I don’t just mean I feel a little hot during the night, I’m talking full blown soaking wet with sweat. It’s awful and having an impact on my life now

I had exactly this at the same age. It passed after a few months, i never found a cause. I got married two years later and had two kids. I am now 40 and think peri menopause is starting now.

MrsBournville · 05/03/2026 18:10

As other posters have said. This can be a red warning flag for blood cancers, you should go back to the GP and request further testing.

Piglet89 · 05/03/2026 18:09

OP: this is not “one of those things”. There will be a medical reason - as PPs have said, push for a second opinion, esp in context of the high white cell count.

Yeah I remember at the time the first doctor (it was in hospital) was concerned about the high white blood cells and said it can show some more serious things, but then the 2nd doctor said it’s fine because that’s something I’ve had before in recent blood tests and she said if it was anything serious it would be much higher and it wasn’t that much higher than normal. I remember she said it was 15.5 and should be 12 I think?

I would be asking for a pelvic exam and swabs, ultrasound scan, repeat blood tests including blood borne virus screening and infection screening.

Worriedmrs · 05/03/2026 18:08

I had this when I had an ovarian cyst. I thought it was because I was in perimenopause but everything became okay after surgery.

My mum had night sweats when she had pneumonia. So it can be caused by infection with or without fever.

Raised white cell count and night sweets is a red flag for a number of things that need further investigation. Go back to a different GP.

Have you any children? How old are they of you do?

HootyMcB00b · 05/03/2026 18:02

Does it follow a pattern with your menstrual cycle or is it more frequent or random? The fact that it happens at night makes it sound hormonal, but I'm no expert.

Anti depressants?

I struggled really badly with a certain type of anti depressant:

how were your liver function results?
