Insomnia: what helps, and what doesn't?

A bad night or a persistent sleep problem?

Insomnia can involve difficulty falling asleep, repeated waking or waking too early and struggling to return to sleep. What happens during the day matters too: tiredness, poor concentration and difficulty coping deserve attention.

Clinicians consider the frequency, duration, daytime effects and opportunity to sleep. A commonly used threshold for chronic insomnia is trouble at least three nights a week for at least three months. This is a classification, not a reason to wait three months before asking for help. NHLBI diagnosis guidance ^[1].

If you searched “why can't I sleep tonight?”, begin with the circumstances of the night. A late shift, an uncomfortable room or worry about tomorrow provides more actionable context than a single number on a space-weather graph.

What can I try tonight?

Make the bedroom dark, quiet and comfortable. Choose a gentle wind-down activity, such as reading, and go to bed when sleepy. Keep a consistent morning rising time instead of repeatedly moving your schedule after a poor night. Avoid late caffeine and using alcohol as a sleep aid. These are starting points from NHS insomnia guidance ^[2], not a guaranteed overnight cure.

Pick a change you can actually describe. “I closed the curtains and stopped working in bed” is more useful in a diary than “I did everything wrong.” A difficult night is not a personal failure or proof that a routine has failed permanently.

Do not drive while sleepy. If tiredness makes a task unsafe, address that immediate problem rather than trying to push through it.

What helps when insomnia keeps returning?

Ask about CBT-I: cognitive behavioral therapy for insomnia. CBT-ICBT-I combines practical work on sleep habits with ways to address the worry and behavior that can keep insomnia going. The American College of Physicians guideline ^[3] recommends it as initial treatment for adults with chronic insomnia.

Sleep hygiene means general habits and bedroom conditions. These can support care, but the AASM behavioral guideline ^[4] advises against using sleep hygiene alone as the treatment for chronic insomnia. If you have already tried a darker room and less coffee, the next step need not be another longer list of bedroom rules.

The sleep-aid distinctions above follow NHLBI treatment guidance ^[5] and NCCIH's melatonin evidence summary ^[6]. “Not established as a general treatment” does not mean a product can never have a specific clinical use.

Prescription medication may be part of an individual plan. Do not start, stop or change prescribed treatment based on this article. Our CBT-I guide explains the newer evidence about combined treatment.

Could the Moon or a magnetic storm be involved?

Lunar sleep studies have mixed results. Space-weather and Schumann measurements are not personal sleep tests. Read full Moon and sleep, space weather and health or Schumann resonance and health for the separate research questions.

If you want to investigate your own pattern, record sleep first and environmental context later. Include uneventful nights. Our sleep diary guide and blank template explain how, without assigning a storm as the cause.

When should I ask for help?

Arrange a clinical assessment if sleep trouble persists, changes in habits have not helped, or daily life is becoming difficult. Mention loud snoring, gasping during sleep, medicines, pain and schedule changes; another sleep or health problem may need attention. These points follow the NHS and NHLBI guidance listed below.

Bring a short sleep record and explain what bothers you most: taking a long time to fall asleep, waking repeatedly, or struggling through the next day. You do not need a wearable, a perfect diary or evidence of a lunar pattern to ask for care.
