Postpartum night sweats

Waking up drenched in the early weeks after birth, sheets damp, is surprisingly common — postpartum night sweats. They can be dramatic, but they’re a normal part of your body recalibrating after pregnancy, and they pass. Here’s what’s going on and how to stay comfortable.

Why they happen. During pregnancy your body held onto a lot of extra fluid and ran on high hormone levels. After birth, your body sheds that excess fluid (through sweat and lots of weeing) and your hormones drop rapidly, and both of these can leave you sweating buckets, especially at night. It’s your body returning to its pre-pregnancy state.

When they happen and how long they last. Night sweats are most common in the first days to weeks after birth and usually settle within a few weeks. If you’re breastfeeding, the hormonal side can keep them going a bit longer for some people. Either way, they’re temporary.

Staying comfortable. A few simple things help:

• Wear light, breathable cotton nightwear and use cotton sheets, and keep a spare set handy for a middle-of-the-night change.
• Keep your room cool — a fan, open window, or lighter bedding.
• Stay hydrated — you’re losing fluid, so drink plenty of water (also important if breastfeeding).
• Lay a towel over your sheet or pillow to save changing the whole bed.
• Have a quick shower or freshen up in the morning to feel human again.

It’s part of the bigger postpartum picture. Night sweats often come alongside the other early changes — bleeding, afterpains, mood swings and exhaustion — as your body and hormones reset. Being gentle with yourself, resting when you can, and knowing it’s all normal helps you ride it out.

When to see your doctor. Night sweats themselves are harmless, but contact your GP if they come with a fever, chills or feeling unwell (which could signal an infection needing treatment), if you have a rapid heartbeat, tremor or weight changes (occasionally a thyroid issue after birth), or if they’re severe, persistent (beyond several weeks), or drenching long-term. And as always, report signs of infection or feeling generally unwell after birth promptly.

Look after your mind too. Broken, sweaty nights on top of newborn sleep deprivation are draining. If you’re also feeling persistently low, anxious or overwhelmed, that’s worth mentioning to your GP or child health nurse — the physical and emotional recovery go hand in hand.

Postpartum night sweats are a normal, if clammy, part of your body offloading pregnancy’s extra fluid and hormones, and they usually settle within a few weeks. Keep cool, stay hydrated, protect your bedding, and check with your GP if you have a fever, other symptoms, or they drag on. It’s one more temporary quirk of the fourth trimester — this too passes.
