## Quick answer

- Sleep often dips before and during periods for some people, especially with PMS or painful cramps.
- Overnight products, tampon timing, warmth for cramps and a cool room help.
- Severe premenstrual symptoms are worth discussing with a GP.

Some people notice their [sleep](https://splash.care/learn/movement-sleep/sleep-cycle) is worse in the days before and during their period. [Cramps](https://splash.care/learn/period-care/cramp-relief), needing the loo, worry about leaks, and [hormone](https://splash.care/learn/cycle-basics/hormones-explained) shifts can all play a part. It does not happen to everyone though.

## What the research says

A 2023 review found that in people with regular, symptom-free cycles, how long and how well you sleep generally stays the same across the cycle, although brain-wave patterns shift a little after [ovulation](https://splash.care/learn/glossary/ovulation) when [progesterone](https://splash.care/learn/glossary/progesterone) is high. Poorer sleep is more common in people with premenstrual symptoms or painful cramps. The NHS lists tiredness and trouble sleeping as common [PMS](https://splash.care/learn/glossary/pms) symptoms.

## Sleep-saving ideas

- **Leak-proofing:** overnight [pads](https://splash.care/learn/period-care/products-compared), period pants, or a cup, plus a dark towel underneath.
- **Tampon timing:** if you sleep for more than 8 hours, a tampon is not ideal (the FDA says never more than 8 hours). Put a fresh one in just before bed and take it out as soon as you wake, or choose a different product.
- **Cramps:** a warm (not hot) hot water bottle wrapped in a cover, or a painkiller before bed if suitable for you.
- **Keep cool:** a cooler room and breathable bedding. Body temperature rises slightly after [ovulation](https://splash.care/learn/phases/ovulation).
- **Wind down:** a regular bedtime, less screen time and less caffeine later in the day, as the NHS sleep advice suggests.
- **Position:** curling up on your side takes pressure off your tummy for some people.

> **Splash says:** log your sleep for a couple of cycles. If you do spot a pattern, you can plan around it, like an early night the day before your period.

> Never fall asleep with a hot water bottle directly against your skin, and do not use boiling water. It can cause burns.

### When to see a doctor

If poor sleep, low mood or anxiety before your period is severe and affects daily life, talk to a GP. The NHS says some people have a more severe form of PMS called PMDD, which is treatable. If you ever feel suicidal, call 999 or go to A&E, or call Samaritans free on 116 123, any time.
