Latest guides

  • Perimenopause insomnia: why it starts and what helps

    Perimenopause insomnia is trouble falling or staying asleep during the years before your final period. In the SWAN study, 31% to 42% of perimenopausal women reported insomnia symptoms in any given year (Obstetric and Neonatal Nursing, 2017). If hot flushes wake you, ask about treatment for them; if nights feel anxious, CBT-I has the strongest trial results.

    Updated

  • Why do I keep waking up at 3am after 40, and what helps?

    Waking at 3am is common after 40, and no single hormone explains it. Sleep gets lighter with age: each decade adds about 10 minutes awake after sleep onset (Boulos 2019, 169 studies). If you are still awake after 15 to 20 minutes, leave the bed and return when sleepy. If you snore or gasp, see a clinician.

Common questions

Why “after 40”?

Sleep changes with age. From midlife you get less deep sleep and wake more often, and perimenopause adds hot flushes and hormone shifts. Most sleep advice is written for 30-year-olds. Every guide here starts from the problems that show up in your 40s, 50s and 60s.

Is it only for women?

No. Menopause has its own section because it breaks so many people’s sleep. The guides on night waking, insomnia, snoring, sleep apnoea and sleep aids are written for everyone over 40.

Where should I start?

With the problem that wakes you. Waking at 3am? Start with night waking. Lying awake for weeks? Start with CBT-I, the treatment sleep guidelines put first. Each guide gives you the answer in its first two lines.
