If you've ever lain awake at 3am, too hot, too uncomfortable or just too wired to drift off, you're far from alone. Women are around 40% more likely than men to experience insomnia. That isn't a willpower problem. It's biology.
From your monthly cycle to pregnancy, the newborn months and menopause, a woman's sleep changes with her body. Good sleep isn't a luxury. It's when your body repairs, your hormones rebalance and your mood resets. Here's what's really going on at each stage, and the small changes that help.
Why women sleep differently
Oestrogen and progesterone both affect how easily we fall asleep and how deeply we stay asleep. When those hormones rise and fall, so does sleep quality.
Around one in three women say cramps, headaches or bloating disturb their sleep during their period. Many notice their worst nights fall in the week before it starts. Add the mental load many women carry, the running to-do list that switches on the moment the lights go off, and it's no surprise sleep can feel fragile.
Pregnancy: when your body is working overtime
Pregnancy is one of the hardest times to sleep well, and the third trimester is often the toughest. Heartburn, leg cramps, a baby who's most active the moment you lie down, back and hip aches, and those 2am bathroom trips all add up.
Position matters too. From 28 weeks, UK guidance is to go to sleep on your side, for night-time sleep and daytime naps. Research found that going to sleep on your back in the third trimester was linked to around twice the risk of stillbirth compared with going to sleep on your side. Left or right side are both fine. If you wake up on your back, don't worry: just roll back onto your side. The charity Tommy's has more on this.
The catch is that side sleeping isn't always comfortable when you're not used to it. Support between your knees keeps your hips aligned. Support behind your back stops you rolling over. Support under your bump takes the pull off your lower back.
The fourth trimester: sleep in short bursts
After birth, hormone levels drop sharply and night feeds break sleep into short pieces. You can't fix newborn sleep, but you can make the sleep you do get count:
- Rest when the baby sleeps, even if you don't fall asleep
- Set up a comfortable, supported feeding position so night feeds don't strain your neck, shoulders and back
- Share night duties where you can, so one of you gets a longer stretch
- Keep night feeds dim and quiet, so you both settle again faster
Perimenopause and menopause: the hidden sleep thief
Hot flushes and night sweats affect 75 to 85% of women going through menopause, and they're a major cause of broken sleep. Falling progesterone, which has a calming effect, can make it harder to drift off too. Breathable cotton bedding, a cooler room and layers you can throw off all help. If sleep problems are affecting your daily life, talk to your GP, as there are treatments that can help.
Five habits that help at every stage
- Keep a steady rhythm. Go to bed and get up at similar times, even at weekends.
- Keep the room cool, dark and quiet. A cooler room helps your body temperature dip, which signals it's time to sleep.
- Wind down without screens. Give yourself 30 to 60 minutes without your phone before bed.
- Watch the late caffeine. Cut off tea, coffee and cola by early afternoon.
- Support your body. Pain and pressure are some of the biggest reasons women wake at night. The right pillow can take the strain off your back, hips and shoulders.
