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

Apart from the menopause, when I often had to get a towel to lie on at 2 am, I’ve only experienced that with some wretched infection - nasty-cold or fluey bug. Most notably, post-menopause, when I was in hospital with pneumonia- I was having to ask someone to change the bottom sheet just about every night, and good old dh was bringing me 2 changes of PJ tops and bottoms every day, and taking the sodden ones away to wash.

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

Do you have other symptoms with the bleeds? I'm asking this because you may want to get checked for Adenomyosis or Endometriosis both of which can have a symptom of night sweats. In the first instance you would need an internal ultrasound to check and possibly a referral to Gynecology.

Womanofcustard · 06/03/2026 17:51

I get occasional night sweats, I have had a raised white blood cell count since at least age 32. I’m 73 now, fairly healthy. GP said some people naturally have this.
OP you should get it all checked, as others have said, but please don’t worry - you may just be, like me, a freak of nature!

SnoopyPajamas · 06/03/2026 17:28

rubytubeytubes · 05/03/2026 18:06

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.

This. Not to alarm you, OP, but some blood cancers can begin in the bone marrow and not elevate white blood cell counts for a while. You need to go to a different doctor and be very clear with them about the extent of these drenching night sweats, and how abnormal they are for you. In addition to the fact that your hormone levels have come back normal. Be calm but clear about the source of your concern.

It's also worth keeping in mind that your white blood cell count could shoot up very fast, if it was leukemia. The picture could look totally different within a matter of weeks. I'd test again in the near future if I was you, just to be safe.

I'm not trying to scare you, but if there's any possibility at all, it needs looking into. Don't let the GP fob you off. Record your appointments and take notes if you don't feel listened to, and don't be afraid to seek out a second opinion. There is no harm in looking into it. Even if it turns out you're fine, you'll have given yourself peace of mind.

toomanydicksonthedancefloor1 · 06/03/2026 17:11

If you have raised white blood cells please don't let this drop. I don't want to be alarmist and I am sure it's a sign of lots of different things, but it does mean something isn't right. For my father in law this was the first early medical sign (which he then ignored for 3 years) of cancer which may have been very treatable at that stage but was terminal by the time other symptoms showed up. Again, I apologise as I realise it probably isn't anything anywhere near as sinister but I had to say it.

bloodcancer.org.uk/understanding-blood-cancer/lymphoma/hodgkin-lymphoma/symptoms/

The most common symptom of Hodgkin lymphoma is one or more swellings or lumps in the neck or above the collarbone. These are swollen lymph nodes (also called lymph glands).

Some people with Hodgkin lymphoma get these symptoms:

  • drenching night sweats (that soak through your clothes or bedding)
  • a high temperature (fever)
  • unexplained weight loss.

Other symptoms that can sometimes happen to people with Hodgkin lymphoma include:

  • tiredness (fatigue)
  • itching
  • increased risk of infections
  • excessive bleeding – such as nosebleeds, heavier periods than usual and spots of blood under the skin.

Do you have a synthetic mattress topper? I had to take mine off the bed as it was making sweat buckets in the night.

Mayflower282 · 06/03/2026 16:58

Meds? Anti-depressants can cause night sweats.

Munchyseeds2 · 06/03/2026 16:50

Night sweets are not normal at your age.

Please go back to the GP ASAP and tell them very clearly, what you are worried about

DisappearingGirl · 06/03/2026 16:46

OP, a boney-feeling lump on the sternum/clavicle can definitely be lymphoma, even in the absence of any other symptoms. Hodgkin's lymphoma often occurs in the mediastinum (inside middle of chest).

Night sweats and high WBC are also risk factors for lymphoma.

Lymphoma, although a cancer, is usually very treatable, but of course better to catch it early.

Please go and get checked again for this and don't be fobbed off. I wish you the best of luck.

Cheeseandmorecheese · 06/03/2026 16:35

You would need to ask for a full blood count including lymphocytes, and examination of your lymph nodes.

Cheeseandmorecheese · 06/03/2026 16:34

cinnamonrolls3 · 06/03/2026 00:11

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

I would strongly recommend going back to the GP as soon as you can and saying you are extremely concerned about possible lymphoma and want to be referred for proper testing. At 28 this is highly unlikely to be your hormones, and it could be extremely serious. You seem to be listing lots of symptoms of potential lymphoma here.

Additup · 06/03/2026 09:03

A friend of mine had this and it turned out to be caused by high blood pressure. She was slim, fit and healthy but unfortunately for her high blood pressure at a relatively young age ran in her family. I think she was late 30s/early 40s at the time.
Once her BP was under control the night sweats stopped.

She had no other symptoms of high BP so it came as surprise to her.

OP I use Isabel symptom checker often, it's very good. I put in your age group, raised white cell count, drenching night sweats, breakthrough bleeding and lump on chest (there was no dropdown for collarbone). Try it, it suggests all the illnesses it potentially could be. Leukemia is the first one listed but there are others, like endometriosis and so on. But be your own best advocate and don't be fobbed off, please. Wishing you all the best with this.

Do you usually have a large or late meal before going to bed? When the digestive system is still working at full speed overnight, it can raise your body temperature and lead to night sweats.

Mysteise · 06/03/2026 00:28

This is a classic symptom of low oestrogen. That’s why you sweat and run hot when postpartum or during peri menopause, because your oestrogen tanks to the floor! I know you said your hormone panel is normal, but unless you know a rough base level from before this started happening, you won’t know if your current oestrogen is lower than your personal ‘normal’ or not. Does it tend to happen more at the very start of your menstrual cycle when every woman’s oestrogen is naturally at its lowest? If so there’s your answer.

For what it’s worth, I’m typically a very cold, oestrogen-dominant person but overheat chronically for months post partum and also when I had a large ovarian cyst. Doesn’t have to automatically mean peri meno.

ImthatBoleyngirl · 06/03/2026 00:27

I'm 46 and have been having terrible night sweats for the past 8 or so years. I wake up completely drenched, I actually have trickles of sweating running off me. It always seems to coincide with when I have a particularly vivid dream, but after reading this thread I'm a little worried......
No other signs of perimenopause yet either.

Rayqueen2026 · 06/03/2026 00:26

Blood tests of any kind can not definitely prove start of pre menopause, yes they can check hormone count etc but they can not say for definite it hasn't started. Doctors go by the signs and based on what your saying it certainly sounds like the start but could go on for years

Have you had your thyroid tested? Excessive sweating can be a sign of overactive thyroid.

OP, on the NHS app you can see all your historic blood test results going back years and years.

It’s worth looking and checking your results and normal ranges.

In Scotland we can’t unfortunately 😢 no nhs app up here

but I’ll absolutely request the numbers and have a look at them. I’m not a doctor so it doesn’t mean much to me but it would be good to see how long the white blood cell thing has been high for

the only other thing that springs to mind is I’ve been told before I have higher than normal blood sugars sometimes but it’s not diabetes or anything to worry about. It’s only sometimes. I remember they did a blood test in a&e (for a totally separate thing) and it checked electrolytes and stuff and the glucose came back at 8. But I hadn’t eaten in around 10 hours by that point and had been vomitting all day, and they said the stress of being sick can cause it to spike. I’ve had it happen a few times in similar scenarios. It went back to normal and it doesn’t sit high all the time so they said it’s not an issue. I don’t think it’s at all related but that’s the only other thing I’ve ever had come back abnormal in the last few months apart from the white blood cells. The highest it went to was 11.5 I’m sure.

dont think its related but its the only other abnormal result in the blood tests, everything else was completely normal x

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

Ionlymakejokestodistractmyself · 05/03/2026 23:30

I changed to all cotton bedding and a thin wool duvet (from IKEA) and my night sweats are now more manageable, but yours sounds extreme and like it could be medical. Hope you get an answer soon.

MariaDingbat · 05/03/2026 23:27

I get bad night sweats sometimes, it was worst post partum with the hormone drop but still happens occasionally. Does it get worse at any particular time in your cycle? Have you started taking any new vitamins or supplements lately?

Can you get the actual numbers of your blood test results? What can be 'in range' can still cause symptoms if it isn't optimum for you. Especially thyroid, vitamin d, vitamin b and Ferritin levels. I was told my iron levels were fine as they were in range, but I was close to needing a transfusion and barely functioning. It's your body and your know yourself so please push for more tests to rule out something sinister.

BauhausOfEliott · 05/03/2026 22:13

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

The awareness of peri-menopause has gone OTT if people blithely put night sweats at age 28 down to that.
And if it was peri then it needs to be established and then looked into and it's not normal to have it so early.
