How to Sleep Better: Science-Based Strategies to Overcome Insomnia

Insomnia — trouble falling asleep, staying asleep, or waking too early — is one of the most common health complaints, and millions of people search for relief every year. The medical consensus, based on clinical guidelines and sleep-medicine research, points to a structured behavioral program rather than medication as the most durable fix.

The first-line treatment: CBT-I

In a 2016 clinical practice guideline, the American College of Physicians (ACP) recommended cognitive behavioral therapy for insomnia (CBT-I) as the first-line treatment for adults with chronic insomnia, ahead of drug therapy. The guideline states that CBT-I combines cognitive therapy about sleep with behavioral interventions — chiefly sleep restriction and stimulus control — plus sleep-hygiene education, and can be delivered through individual or group therapy, telephone or web-based programs, or self-help materials.

According to the Sleep Foundation, a typical course of CBT-I runs six to eight sessions, and 70% to 80% of people with primary insomnia see measurable improvement, including falling asleep faster and fewer awakenings during the night.

The five techniques inside CBT-I

A step-by-step starting point

1. Keep a sleep diary for one to two weeks, noting bedtime, wake time, and roughly how long it takes to fall asleep — the basis for sleep restriction, per the Sleep Foundation.
2. Set one fixed wake-up time every day, including weekends, as the CDC recommends.
3. Only go to bed when sleepy, not simply because it is a set hour.
4. If you are not asleep within about 10 minutes, get up and return to bed only when drowsy again — the stimulus-control rule described by the Sleep Foundation.
5. Use the bed only for sleep (and sex); do work, scrolling or television elsewhere.
6. Limit total time in bed to match your diary's average sleep time, then extend it gradually as sleep improves, following the sleep-restriction approach.
7. Add a nightly relaxation practice — slow breathing or progressive muscle relaxation — to wind down before lights-out.
8. During the day, get natural light exposure and regular physical activity, but avoid exercising within a few hours of bedtime, per CDC guidance.
9. Avoid caffeine in the afternoon and evening, skip heavy meals and alcohol close to bedtime, and dim screens at least 30 minutes before bed, per the CDC.
10. If symptoms persist after several weeks of self-directed steps, ask a clinician about a structured CBT-I program (in person, by phone, online, or through a workbook) before starting sleep medication.

How much sleep is enough, and where medication fits

The CDC advises that adults aged 18 to 60 get 7 or more hours of sleep per night; those 61 to 64 should aim for 7 to 9 hours, and adults 65 and older for 7 to 8 hours. Using 2014 data, the American Academy of Sleep Medicine reported that only 65% of U.S. adults met the 7-hour threshold, meaning an estimated 83.6 million U.S. adults were sleeping less than recommended.

On medication, the ACP guideline says sleep drugs are FDA-approved only for short-term use — about four to five weeks — and that patients who see no improvement within 7 to 10 days of starting a drug should be re-evaluated. The guideline recommends shared decision-making between doctor and patient before adding medication, and only after CBT-I has been tried or discussed, weighing benefits, harms and costs.
