If you're waking at 3am, kicking off the covers or lying awake with a busy mind, you're far from alone. Sleep often changes in perimenopause and menopause. What many women don't realise is how much those rough nights affect their weight.
How poor sleep affects your weight
After a bad night, a few things happen:
- Hunger hormones shift. Ghrelin, which makes you hungry, tends to rise. Leptin, which helps you feel full, tends to fall.
- Cravings get louder. Tired brains look for quick energy, usually sugar and refined carbs.
- Willpower drops. Decisions feel harder when you're exhausted, including food decisions.
- Movement falls. You're less likely to exercise and more likely to sit.
Over weeks and months, these small effects add up.
Why sleep changes after 40
Falling oestrogen and progesterone can affect body temperature, mood and sleep quality. Hot flushes and night sweats wake many women. Stress, a busy household and caring responsibilities often add to it. Alcohol, which many women use to wind down, also disrupts deep sleep later in the night.
Simple steps that help
- Keep a regular schedule. Go to bed and get up at similar times, even on weekends.
- Cool your bedroom. Lighter bedding, a fan and breathable pyjamas help with night sweats.
- Cut caffeine after midday. Some people process caffeine slowly, and it can linger for hours. I explain why in my post on DNA testing for weight loss.
- Go easy on evening alcohol. Even one or two drinks can affect sleep quality.
- Get morning light. Ten minutes outside early in the day helps set your body clock.
- Build a wind-down routine. Screens off, lights low, and something calming like reading or stretching.
If sleep problems are severe or ongoing, speak with your GP. There may be options worth discussing, and sleep apnoea becomes more common after menopause too.
Sleep is part of the plan
When I work with women over 40, sleep is always part of the conversation. It's hard to stick with any eating plan when you're running on empty. Often, small improvements to sleep make the food changes feel much easier.
If you're also noticing changes around your middle, my post on menopause belly fat explains how sleep, hormones and muscle all connect.
