How to Stop Sweating at Night During Pregnancy

If you’re waking up at 2 a.m. sweaty and uncomfortable, you’re not alone. Night sweats during pregnancy are often tied to shifting hormones, including estrogen and progesterone. The good news is that you can try several simple, at-home changes tonight, mostly focused on cooling your body, reducing overheating, and keeping your routine consistent.

Start with the basics: cool down your sleep setup

Before you change anything else, fix your sleep environment. Night sweats often get worse when your room runs warm or your bedding holds onto heat.

Tonight, try this:

• Turn on a fan and aim it so air can move around you (not just blow straight at your face).
• If you can, use an air conditioner or another way to keep the room cool.
• Keep air circulating. Still, warm air can make sweating feel more intense.
• Pay attention to your bedding. If you’ve been using heavy comforters, switch to something lighter for the next few nights.

If you do one thing after reading this, make it: cool the room and improve airflow.

Hydration and temperature control: what to do before bed

Sweating is easier to manage when your body isn’t already running hot and off-balance. Hydration won’t eliminate night sweats overnight, but it can help you feel steadier.

Here’s a simple bedtime plan:

• Drink water earlier in the evening, not only right before you fall asleep.
• Keep a glass of cool water at your bedside. If you wake up sweaty, take a few sips right away.
• If you’re waking up thirsty, it can be a sign you’re too warm or too dry overnight. Adjust how you hydrate earlier in the evening.

A small habit that helps: when you wake up, cool down first (cool water, then airflow). Then decide what to change next, instead of jumping straight into “I guess I’ll just deal with it.”

Clothing and bedding choices to reduce overheating

Even with a cooler room, thick layers can trap heat and keep you from feeling relief. The goal is simple: breathable, not bulky.

Try these changes:

• Wear breathable sleepwear, ideally soft, lightweight fabrics that don’t feel hot against your skin.
• Choose bedding that doesn’t feel heavy or heat-trapping.
• If your pajamas or underwear feel warm by bedtime, switch to something lighter tonight.
• If you wake up sweaty, keep a spare layer nearby. You may need to change things, but you don’t want to stay fully awake just because you’re uncomfortable.

Small changes really can add up here. If you’re sweating every night, you usually don’t need a dramatic overhaul. You need fewer heat-traps.

Use antiperspirant and daily hygiene steps

This part is straightforward, and it can make a real difference—especially if your sweating is heavy at night.

Do this:

• Wear an antiperspirant. Antiperspirant helps reduce sweat more than regular deodorant.
• Stick to daily hygiene, and wash or shower regularly each day.
• If you feel like you’re sweating more than usual, wash more frequently if you need to.

If using antiperspirant during pregnancy is new for you, it’s still a simple comfort step. Use it the way you normally would and follow any routine instructions your clinician has given you.

Bedside routine: fan/air circulation and cool water

When you wake up sweaty, repeat this routine. The goal is to cool you down quickly, then help you get back to sleep.

When you wake up:

1. Grab the cool water from your bedside and take a few sips.
2. Use the fan to keep air moving over your body.
3. If you can, remove or loosen one layer (like a heavier top or extra blanket) for a few minutes.
4. Let the cool air work before you try to adjust everything else.

This is also why it helps to keep your bedside setup simple. You don’t want to hunt for water or fumble with a bunch of items while you’re half-asleep and uncomfortable.

Trimester-by-trimester: first trimester changes and what to try

Night sweats in early pregnancy can be especially frustrating because your body is adjusting fast. If you’re dealing with night sweats in early pregnancy, focus on gentle, easy comfort fixes you can start right away.

For the first trimester, try this:

• Keep the bedroom cool with a fan and air conditioning if you have it.
• Use breathable layers that won’t trap heat.
• Start your day-to-night routine with hydration earlier in the evening, plus a glass of cool water at your bedside.
• Use antiperspirant and stay on top of regular washing or showering.

If nausea or fatigue is also part of your nights, keep the routine simple and automatic: fan on, cool water ready, and lighter bedding.

And don’t ignore how intense your symptoms feel. If your night sweats come with other warning signs, don’t just assume it’s normal pregnancy stuff.

Trimester-by-trimester: second trimester adjustments

Second trimester can feel more stable, but night sweats don’t always go away. If you’re looking for how to stop sweating at night during pregnancy in the second trimester, the main strategies stay the same—you just may need to fine-tune what “comfortable” means as your body changes.

Try adjusting:

• Bedding weight and layers, since you may warm up faster now.
• Fan direction, so you feel cool where it counts instead of just having air around you.
• Hydration timing, so you’re not constantly waking for bathroom trips, but still keep cool water by your bed for quick relief.
• Antiperspirant and hygiene, so you don’t skip steps if sweat starts creeping up.

Second trimester is also a good time to watch for patterns. For example: do you sweat more after spicy food, after a warm shower close to bedtime, or with heavier blankets? A few small tweaks can help.

Trimester-by-trimester: third trimester night sweats and sleep

By the third trimester, sleep can already be hard. Night sweats can make it feel like you’re stuck fighting your own body. If you’re asking how to stop sweating at night during pregnancy in the third trimester, aim for maximum comfort with minimal effort.

Focus on:

• Strong temperature control, including a fan for airflow and air conditioning if it’s available.
• Breathable sleepwear and lighter bedding, since your body may heat up sooner than before.
• Cool water at your bedside, so you can act quickly without fully waking up.
• Antiperspirant and regular washing, so you feel fresher when you wake.

Also, keep your bedside routine “grab and go.” In late pregnancy, you don’t want one sweaty wake-up to turn into a 20-minute production.

If you use multiple pillows or change positions often, set things up so you don’t have to reach far when you wake. Accessibility matters when you’re tired.

When to worry: is sweating a symptom of preeclampsia?

This is the safety question you should not ignore.

Is sweating a symptom of preeclampsia? Night sweats alone aren’t the clearest sign, but if you’re pregnant and your symptoms feel off, it’s worth checking in—especially if you have other warning signs.

Because preeclampsia can be serious, contact your healthcare provider promptly if you have night sweats along with symptoms like:

• High blood pressure (if you’ve been told you have it)
• Severe or persistent headaches
• Vision changes
• Right upper belly pain (under the ribs on the right side)
• Swelling that feels sudden or severe, especially in the face or hands
• Shortness of breath or feeling suddenly very unwell

If you’re unsure whether your symptoms match, don’t try to reason it out on your own. Tell your clinician what’s happening, how long it’s been going on, and whether you have any other symptoms.

FAQ: is it normal to have night sweats every night while pregnant?

It can be normal to have night sweats during pregnancy, and they’re often tied to hormone shifts. That said, having night sweats every single night can still be miserable. It may mean you need to adjust your routine, or it may be a good idea to check in if anything else feels wrong.

For many people, night sweats improve when you:

• Keep the room cool (fan/airflow, and air conditioning if you need it)
• Use breathable clothing and lighter bedding
• Stay hydrated and keep cool water by your bed
• Wear an antiperspirant
• Wash or shower regularly, and more often if you need to

If you’ve tried the cooling + hydration + breathable bedding steps for a few nights and you still feel very uncomfortable, or if you notice concerning symptoms along with sweating, it’s smart to contact your healthcare provider for personalized guidance.
