If you fall asleep fine but wake at 3 a.m., you are far from alone. Here is what changes in midlife and the habits that make the biggest difference.

Key takeaways
  • Adults need at least seven hours of sleep a night.
  • Hormonal shifts, night sweats, stress and a higher risk of sleep apnea all play a part in midlife.
  • A consistent wake time is one of the most effective single changes you can make.

Sleep problems are one of the most common complaints women bring to their doctors in their 40s and 50s. Some of the reasons are hormonal, some are about the stage of life, and several are fixable.

What is going on

Habits that make the biggest difference

Anchor your wake time

Getting up at the same time every day, weekends included, steadies your body clock more reliably than trying to force an earlier bedtime.

Keep the bedroom cool

A cooler room, breathable bedding and layers you can remove help with night sweats. Many people sleep best somewhere around the mid-60s Fahrenheit.

Watch the afternoon caffeine and evening alcohol

Caffeine can stay in your system for many hours. Alcohol may help you drift off, but it fragments sleep in the second half of the night, which is exactly when midlife sleepers tend to wake.

Get daylight early

Morning light, even on a cloudy day, helps set your internal clock and can make it easier to feel sleepy at night.

If you wake, do not fight it

If you have been lying awake for what feels like 20 minutes, get up and do something quiet in dim light until you feel sleepy again. This keeps your bed linked with sleep, not frustration.

When to get help

If poor sleep lasts more than a few weeks, affects your days, or comes with loud snoring or pauses in breathing, talk to a clinician. Cognitive behavioral therapy for insomnia (CBT-I) is a well-studied first-line treatment, and menopause symptoms that disturb sleep can be treated too.
