Latest guides
- Magnesium for sleep: what the 2026 review of 12 trials found
Magnesium may help some adults sleep a little better, but the evidence is weak. A 2026 review of 12 randomized trials found inconsistent results, low to very-low certainty, and no support for routine insomnia use (Journal of Dietary Supplements, 2026). The NHS says 400 mg a day or less from supplements is unlikely to cause harm.
- Why does my anxiety get worse at night in midlife, and what helps
Anxiety feels worse at night because the day's distractions are gone, poor sleep raises next-day anxiety, and midlife adds hormones, alcohol, caffeine and reflux. Among 2,956 US women, odds of high anxiety were 56-61% higher after the menopausal transition began (SWAN, 2013). Write worries down earlier in the evening; if worry is daily, see a clinician.
- Remedies for menopause night sweats, ranked by evidence
The best-supported remedies for menopause night sweats are hormone therapy, cognitive behavioral therapy, clinical hypnosis, and some non-hormone drugs. Hormone therapy cut hot flush frequency by about 75% in a Cochrane review of 24 trials (2004). Black cohosh and other herbal supplements are not recommended. Take this ranking to your clinician and start at the top.
- Sleep aids for menopause compared: what the evidence says
The best-supported sleep aid for menopause is CBT-I, a talking therapy, which cut insomnia scores 5.2 points more than control in a pooled analysis of 546 women (Sleep, 2018). Over-the-counter antihistamines are advised against for older adults (AGS Beers 2023).
- Progesterone for sleep in perimenopause: what the trials show
Oral micronized progesterone is a bedtime hormone capsule, and the sleep evidence is small. A 2021 meta-analysis of 9 trials (388 participants) found it shortened time to fall asleep by about 7 minutes (J Clin Endocrinol Metab, 2021). If flushes wake you, ask a clinician about treatment. NICE recommends menopause-specific CBT for flush-related sleep problems.
- Sleep restriction therapy at home: a two-week worked example
Sleep restriction therapy limits your time in bed to roughly the time you actually sleep, then lengthens it as sleep efficiency improves. The AASM suggests it for chronic insomnia (conditional, 2021). If you have bipolar disorder, a seizure disorder or drowsy-driving risk, do it only with a clinician; otherwise read the worked example below.

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.
