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

This isn't normal, it's not 'one of those things' and it needs to be looked at. Peri can happen early. Have you had a full blood count esp b lymphocytes, my Dad has blood cancer (CLL) and sweats was one of his symptoms. I'm not saying it's that at all but there are conditions that cause this, some relatively benign other not so much, so being fobbed off isn't acceptable.

Jasper90 · 05/03/2026 23:00

I had this when I had a chest infection. It was sorted with antibiotics. My C reactive protein result was high

DelilahBucket · 05/03/2026 22:56

I went through this a few years ago. I was mid 30's. I thought it was to do with peri as I had previously been told I would have menopause early. I changed all of the bedding to high quality cotton and a down duvet and pillow and that did make a huge difference.

Brantastic · 05/03/2026 22:50

Just echoing pp's comments re lymphoma- night sweats was one of my mum's first symptoms and by the time it was picked up it was too late. Not trying to scare you and you've very much got age and health on your side but please do get checked out again

whatisheupto · 05/03/2026 22:39

Don't even give a thought to 'what the doctors might think of you'. Just go, and make sure you request to see a different doctor. And when you see them, don't minimise your symptoms or apologise. On the contrary. You need to be insistent to make sure you get seen to properly.

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.

It is insanely unlikely that the OP is in perimenopause at 28.

MushMonster · 05/03/2026 21:08

Reading other comments, they mention lymphoma a lot. I did not know that.
Go back to the doctor and have it checked.

MushMonster · 05/03/2026 21:04

cinnamonrolls3 · 05/03/2026 19:52

But wouldn’t the hormone blood test have picked up some hormone changes if it were that? I really hope it’s not menopause, I’ve always wanted to have kids some day and thought I had ages ☹️ I don’t want to be menopausal at 28

Peri- menopausal.
It can take years and years.
Nights sweats was my first weird symptom. It was 10 years ago. I still have regular periods LOL

TowerRavenSeven · 05/03/2026 20:49

I don’t want to scare you but look into this further. I was 24-25 when I had drenching night sweats and a few years later I was diagnosed with Hodgekin’s Lymphoma, so the white blood cell count would concern me. The average age for this is 27 and later around early 60’s. The other symptoms I had early were teeth breaking off, very itchy skin, then later (two years) enlarged lymph nodes and spleen pain (pain in my side). I was diagnosed stage 3B with 4B being worst so I guess I’m telling you now that to not ignore this because if by some chance it is this you will have caught it early. Don’t wait like I did!

I made a full recovery, got married at 36, had ds at 38, and am now 62 and have been married almost 26 years. Get it checked!! All the best to you.

namechange0998776554799000 · 05/03/2026 20:15

The sweats you've described are classic lymphoma, and you're a very typical age to get it.

My lymphoma was stage 4 before it was diagnosed, by that point my tumour had been growing for two years and was 10x10cm. I was only diagnosed because it broke through my sternum causing a small lump.

I always make a point of mentioning this on here when people mention lymphoma symptoms, because it so often goes undiagnosed. I didn't actually have any symptoms, some people don't, but they include:
Drenching night sweats
Itching all over
Loss of appetite and/or weight loss
Slightly raised temperature
Enlarged lymph nodes

Like I said though, often people have just one or even none of these symptoms.

If you have any others on the list, please do go back to the GP. Diagnosis would come through a full blood count, examination of lymph nodes, and maybe scans if they find anything. It's worth noting that blood tests can sometimes be normal even if you do have lymphoma.

Of course it's very possible it isn't lymphoma and I'm not trying to scare you, but it's better to be safe than sorry! I wish mine had been diagnosed earlier.

damelza · 05/03/2026 20:15

@cinnamonrolls3 It's the cumulative appearance of symptoms that I would want checked, and pronto. Others have pointed out the possibility of Hodgkins etc. I'm not saying that's what you might have, but please, demand that you get thoroughly checked for that before messing around with any other theories. The other possibilities are not seriously life threatening, but lymphoma can be if not caught on time and treated.

I can understand that (like most people) you may want to convince yourself that it is something more benign and attribute it to this or that. Understandable, but I wouldn't waste any more time speculating TBH.

If it turns out NOT to be Lymphoma, then you can get every other test under the sun to try and identify the cause. Please don't delay and self diagnose. I hope it is something simple enough to solve, but you have to rule out other causes before that.

Bless you. I was in denial myself about an illness, until someone kicked me up the backside and I am so glad they did now, but it took me a while to stop thinking it was something else entirely!

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.

Same here ovarian cyst and I was only 26 , one of my friends had one too same symptoms she was 27. I ignored it to start with, because I could manage it & I put it down to stress and life changes ( divorce, house move, new job etc) but after about 6 months my stomach suddenly ballooned and I was beginning to struggle with pain & obviously my clothes weren't fitting me because I looked about 6 months pregnant and then I started passing out as well. One day the pain was so bad it took me all day to get out of bed and walk round the corner to the pay phone so I could ring in sick as I was on night shift. Don't let it get that far OP, go back to Dr & get a second opinion , ask for tests it might be nothing but at least you'll be sure.

Sorry not to drip feed (just didn’t think it was relevant) I’m just a bit worried about going back constantly to the doctor because i think they already have me down as being a bit anxious anyway. I found a new hard lump last year on the end of my collarbone in the middle of my chest on the left side, on the end of the bone itself not a lymph node). The gp wasnt sure what it was, referred me to hospital, they said the x ray was clear and it doesn’t need any treatment, but also don’t know what it is other than some people just have asymmetrical collar bones but Ive never had it before🤷🏼‍♀️it’s not painful so not causing a problem. They’re just not sure what it is or why it suddenly started and grew within a 4 week timeframe last year. It hasn’t gotten any bigger since I had it Xrayed and it’s just the same and it’s not sore at all. But because I was at the doctor with that, and then these symptoms, and also a few other unrelated things from a different condition altogether, I think they definitely have me down as anxious and I’m just worried about adding to that.

It’s so frustrating not knowing but I was sure it would be my hormones but they were all totally fine (which is good obviously, but it means I’m no further forward to fixing the problem)

yeah my b12 was checked and it was totally fine too x

Please put this anxiety aside, you are feeling poorly and have legitimate concerns and reasons to consult a doctor. You really aren’t the type of patient they would be concerned is time-wasting. Please see a doctor who can help, you deserve it.

myheadsjustmush · 05/03/2026 20:08

A few posters have mentioned Lymphoma.

My DH, who is much older than you, had drenching night sweats - so bad the sheets and pillows were soaking wet through.

To cut a very long story short, he was subsequently diagnosed with an aggressive type of Non Hodgkin Lymphoma. His white blood count was also high.

Please go back to your GP @cinnamonrolls3 and push for further tests - if only to rule out Lymphoma once and for all.

I hope you get this sorted OP. X

MrsLizzieDarcy · 05/03/2026 20:07

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?

mindutopia · 05/03/2026 17:59

I would want to be tested for blood cancers (lymphoma, leukaemia, those sorts), especially with the high wbc. Those are the classic two markers of blood cancers. Don’t be fobbed off with its ‘just perimenopause.’ 🙄

This! My MIL had terrible night sweats for more than 2 years. GP diagnosed depression, anxiety, later-menopause. She had a brain tumour.

I am shocked that the doc didn't immediately suspect something with a lump on the collar bone, drenching night sweats and a high WBC. Come on.....

Forget about hormones for a bit and go back and TELL them you are concerned that it could be lymphoma or similar. Demand tests to either rule it in or out. If ruled out then explore other possibilities. I am sorry if I have scared you by saying the above, but it's better to know and get treatment started asap if it proves to be anything other than hormonal.

Go tomorrow if you can and stamp your foot. This is too serious to be fobbed off.

Ah sorry I haven’t explained it well. The lump was last year and at the time I didn’t have any of the night sweats or any symptoms at all, that only started a few months ago. I just went to the doctors because I had found the lump. I only found out about the white blood cells last month although according to what they said it’s been high before? No idea how long for though or how high before. I remember when I was referred for the lump they did bloods at the time and said it was fine and all normal x

Test your estrogen levels, that result will tell you if you’re perimenopausal.

Also are you on any medication? I had night sweats 10 years ago, also no obvious reasons, my doctor increased my antidepressant dose which put a stop to them, until perimenopause started and now HRT patches has stopped them.

Feel for you. Night sweats are horrific.

Thanks, no not on any medication and not on any birth control at all, yeah the blood test included oestrogen (I’m 99% sure but I’ll go and double check) and everything was well within normal range x

tillstwo · 05/03/2026 19:58

I’m not sure this really helps but I had the same thing, it started out of nowhere age 34. I had the hormone tests and all came back normal but when I got pregnant both times it stopped so I can only think it’s hormonal

cinnamonrolls3 · 05/03/2026 17:59

Nah no foreign travel recently. I’m not stressed or undergoing any life changes right now, I’m so happy apart from this😅 I don’t think I’m perimenopausal plus my hormones were all normal which I’m asssuming wouldn’t be the case if I were perimenopausal? Might be wrong though

I get bad night sweats with infections and also if I eat cheese.

months is too long for infections.
