Why Am I So Exhausted? Perimenopause Fatigue Explained
The short answer
"I used to think I was just lazy"
You wake up tired. By 3pm you could lie down on the office floor. You used to get through the day without thinking about it, and now even small things feel like effort. And because nothing looks wrong from the outside, you wonder if it’s just you.
It isn’t. Fatigue is one of the most common things women notice in perimenopause, and it’s real.
How it's different from ordinary tiredness
Ordinary tiredness usually lifts after a good night’s sleep or a quiet weekend. Perimenopause fatigue often doesn’t. It can feel heavy and constant, show up as a crash in the afternoon, or come with feeling flat, foggy or short-tempered. Some women describe it as being wired and tired at the same time.
Why it happens
Your hormones are changing. In perimenopause, oestrogen and progesterone rise and fall unevenly. That can affect your sleep, your mood and how energetic you feel.
Your sleep gets broken. Night sweats, waking at 3am, or lying awake with a busy mind all add up, even if you’re in bed for eight hours.
You’re carrying a lot. This stage of life often comes with teenagers, ageing parents, work and a household to run. Thinking for everyone is tiring in its own way, and it never switches off. I call this the invisible load.
Your energy dips when meals are uneven. Skipping breakfast, grabbing something quick at lunch and running on sugar and caffeine can set up the afternoon crash.
Five daily habits that help
- Protect your sleep. Keep a regular bedtime and give yourself a 15 minute wind down: screens off, lights low, something calm. A cooler bedroom helps if night sweats wake you.
- Steady your blood sugar. Start the day with protein, and build meals around protein and vegetables so your energy doesn’t spike and crash.
- Move, even when you’re tired. A 10 minute walk or a short strength session often gives you more energy than it uses. Daylight in the morning helps your body clock too.
- Give your nervous system a break. Three minutes of slow breathing (in for four, out for six) can calm a body that’s been on alert all day.
- Put one thing down. Look at what you’re carrying and hand one small thing back this week. My free Invisible Load workbook helps you see where your energy is really going.
If you’d like a gentle, week by week way to build these habits, the 5R Blueprint is made for exactly this kind of tired.
When to see your GP
- Your tiredness is severe, or hasn’t improved after a few weeks of looking after your sleep and routine
- You also notice weight changes, breathlessness, heavy periods or feeling low
- You’re snoring loudly or stop breathing during sleep (someone else may notice this)
- You’re struggling to cope day to day
