Waking Up At 3am And Can’t Get Back To Sleep? Why It Happens, And What Helps
Waking up at 3am: the short answer
Waking up at 3am and lying there with a racing mind is one of the most common sleep complaints there is. It is usually a body that is tired with a brain that is still running: long stress keeps the nervous system’s accelerator pressed down, and in perimenopause and menopause, night sweats and hormone swings add to it.
The fix is not more effort at bedtime. It is teaching the body to find its brake, by day and by night. Here is the article in short form:
- Sleep needs the brake; long stress keeps the accelerator down.
- Stress and poor sleep feed each other in a loop.
- 22 insomnia trials: about 111 more minutes of sleep a night.
- Time awake in the night fell by about 56 minutes.
- Menopause sleep improves with yoga, several reviews say.
- In the night: a slow out-breath, not a phone.
A quick word on Iyengar yoga. Iyengar yoga is the style developed by Mr BKS Iyengar. In the 20th century he did more than anyone to set down traditional Indian yoga, through his books and his teaching, and he pioneered the use of props. It is the style we teach at Flametree, in Darwin and live online.
Supported poses in the evening press the body’s brake. The lively work belongs earlier in the day.
Why do I wake up at 3am?
Because sleep needs the brake, and long stress keeps the accelerator down. To fall asleep and stay asleep, the body has to shift into “rest and digest”. Under long stress the heart stays a little faster, the muscles a little tighter and the mind a little busier. So sleep is lighter and more broken, and the early hours, when sleep is lightest, are when you surface.
Then the loop closes. Dr Peter Attia explains it in his book Outlive: stress and a poor night both press the accelerator, and both push up cortisol, blood pressure, heart rate and blood sugar. A bad night makes the next day’s stress harder to carry, which makes the next night worse.
Stress keeps the brain running at night, and poor sleep makes the next day harder to carry. Yoga breaks the loop in two places.
Why does menopause make me wake at 3am?
Falling oestrogen hits sleep from several sides. The brain’s thermostat misfires, so night sweats and hot flushes wake you. Mood and anxiety swing. Women in perimenopause often describe exactly this pattern: asleep fine, awake at three.
Lisa Knopp, an American writer and teacher, began yoga in 1982 in a small class taught in the tradition of Mr Iyengar. In her forties the hard part was the night: night sweats, insomnia and “the heavy moods of perimenopause”. When she woke at three in the morning with her mind racing, she would get up, do a slow series of Sun Salutations, and go back to bed calm.
Several reviews now rank yoga and other non-drug approaches among the best first steps for poor sleep around and after menopause.
Does yoga really help you sleep through the night?
The biggest review yet says yes. A 2026 review in BMJ Evidence-Based Medicine pooled 22 trials with 1,348 people with insomnia, testing seven kinds of exercise. Compared with usual care or lifestyle advice, in people’s own sleep diaries:
- Total sleep went up by about 111 minutes a night.
- Falling asleep took about 29 minutes less.
- Time awake in the night fell by about 56 minutes.
Yoga came out among the most effective exercises for insomnia. Give it up to 12 weeks.
Different people, different trials, the same direction: people with poor sleep slept longer and better with yoga.

What should I do when I wake at 3am?
Press the brake, quietly. Each breath in speeds the heart a little; each breath out slows it. So lie still and let the out-breath grow longer than the in-breath, without forcing. Counting breaths helps many people.
Dr Timothy McCall tells, in Yoga as Medicine, of Chris Martin, a doctor caring for newborn babies, who was woken in the night for days at a time and often lay awake for hours at home. The Iyengar teacher and sleep researcher Roger Cole gave him a firm sleep routine, and his sleep improved. He found Legs Up The Wall, propped on hospital pillows in the on-call room, a good way to wind down. Now, if he wakes in the night, counting his breaths usually gets him back to sleep.
Leave the phone where it is. Light and news press the accelerator again.
Forward bends with the head resting quieten a busy head, in the Iyengar tradition. Ideal for the evening.
What helps stop 3am waking for good?
Change the day as well as the night.
- Lively by day, quiet at night. Strong poses belong earlier in the day. The evening is for supported poses and slow breathing.
- Rest the head. Forward bends with the forehead supported quieten a busy head, in the Iyengar tradition and in our experience.
- Turn upside down, with support. Geeta Iyengar called Legs Up The Wall “nectar for those who do it”. Students commonly tell us they sleep especially well after a restorative class.
- Keep the clock steady. Professor Matthew Walker, a sleep researcher, stresses the same bedtime and waking time every day, weekends included, and morning daylight helps set the body clock.
Insomnia is what first brought me to yoga. It came soon after my mother died, when I was in my late thirties. I no longer suffer from it. I put that down to my practice of the poses and pranayama (breathing practice), and later to some simple sleep habits. It is why I kept going.

Frequently asked questions
Is waking up at 3am a sign of stress?
Often. Long stress keeps the nervous system’s accelerator down, so sleep is lighter and you surface in the early hours when sleep is lightest. Hormone changes, heat and a full bladder can also wake you.
Why can’t I get back to sleep after waking up?
Because the brain switches on before the body has settled. Once the mind starts racing, the heart speeds a little and the alarm feeds itself. A slow, long out-breath presses the body’s brake and gives the mind something quiet to do.
Should I get out of bed if I wake at 3am?
If you have been awake a long time and are getting wound up, getting up for something quiet can help. Lisa Knopp, a long-time Iyengar student, would do a few slow Sun Salutations and go back to bed calm. Keep the lights low and leave the phone alone.
Does menopause cause early morning waking?
It often contributes. Falling oestrogen brings night sweats, hot flushes and mood swings, which break sleep. Several reviews rank yoga and other non-drug approaches among the best first steps for poor sleep around and after menopause.
How much can yoga improve insomnia?
In a 2026 review of 22 insomnia trials, exercise including yoga added about 111 minutes of sleep a night, cut time awake in the night by about 56 minutes, and helped people fall asleep about 29 minutes faster, in their own sleep diaries.
What yoga should I do in the evening for better sleep?
Quiet, supported poses and slow breathing: forward bends with the head resting, supported Legs Up The Wall and lying back over a bolster. Strong poses belong earlier in the day, because they wake the body up.
How long does it take yoga to fix 3am waking?
Give it up to 12 weeks of regular practice, which is how long many sleep trials ran. Some people sleep better after their first restorative class. Steady bedtimes and morning daylight help the practice work.
