How we rate the evidence
High means the method is backed by clinical guidelines and a substantial body of controlled research. Moderate means guidelines support it with fewer or lower-certainty studies. Limited means results are mixed, indirect, or too dependent on the person and setting.
CBT-I
Cognitive behavioral therapy for insomnia combines several techniques, usually including stimulus control, sleep restriction, cognitive work and relaxation. The American Academy of Sleep Medicine gives CBT-I a strong recommendation based on 49 studies. For chronic insomnia, this is the first option to look for rather than collecting more bedtime hacks.
Stimulus control
Go to bed when sleepy, use the bed for sleep, and leave it when you are awake long enough to become frustrated. Return only when sleepy again. The aim is to reconnect bed with sleep instead of worry, scrolling or clock-watching. AASM suggests it as a single-component treatment.
Relaxation training
Progressive muscle relaxation, slow breathing and guided imagery can reduce physical and cognitive arousal. AASM suggests relaxation therapy as a single-component option. It works better as regular practice than as a desperate test performed once at 2 a.m.
Regular exercise
Aerobic and resistance exercise can improve sleep quality, particularly when practiced consistently. Exact timing and the best exercise type remain uncertain. Choose something sustainable; there is no need to exhaust yourself right before bed.
Calming music
Some reviews find small improvements in sleep onset or self-rated sleep, while others find no clear benefit in people without a sleep disorder. Music is low risk if it helps you wind down, but it should not replace treatment for ongoing insomnia.
Putting the phone outside reach
Late-night phone use can delay bedtime and keep the bed associated with wakefulness. Moving the phone away supports stimulus control and removes an easy escape route. GoalLock can add a sleep goal before social apps open, but it is a support tool, not insomnia treatment.
Sleep restriction therapy — Moderate evidence, professional guidance preferred
This method temporarily narrows time in bed to consolidate sleep, then expands it as sleep becomes more efficient. It can increase daytime sleepiness at first and is not suitable for everyone. People with bipolar disorder, seizure risk, safety-sensitive work or other health concerns should discuss it with a clinician.
A fixed wake time — Moderate evidence as part of CBT-I
A consistent wake time strengthens the sleep-wake rhythm and helps build sleep pressure for the next night. The evidence is strongest when it is part of a broader behavioral plan. Sleeping late after a bad night may feel helpful but can keep the cycle unstable.
Sleep hygiene alone — Limited evidence for chronic insomnia
A cool, dark room, less caffeine and a predictable wind-down routine are sensible foundations. They are not a complete treatment. AASM specifically advises against using sleep hygiene by itself for chronic insomnia because stronger treatments are available.
When to get help
Talk with a qualified clinician if sleep difficulty happens at least several nights a week, lasts for months, affects daytime functioning, or comes with loud snoring, breathing pauses, severe mood changes or unsafe sleepiness. Those signs need assessment, not another relaxation video.
