How to Fall Asleep Fast: 10 Methods Ranked by the Evidence

Most advice on falling asleep fast is untested. We went through the published research and ranked what we found, strongest evidence first. None of these is instant, but several have measurable effects.

1. A warm shower or bath, one to two hours before bed

Evidence: good. A meta-analysis of 17 studies found that a warm shower or bath at 40 to 42.5 °C (104 to 108.5 °F) improved sleep quality, and when taken one to two hours before bed for as little as 10 minutes it shortened the time to fall asleep (Haghayegh et al., 2019). Timing is the point: the warmth draws blood to your skin, and your core temperature then drops faster, which is one of the body's own signals for sleep.

2. Use the bed only for sleep

Evidence: good. Go to bed only when you feel sleepy. If you are not asleep after what feels like a while, get up, do something calm in dim light, and come back when sleepy. Keep the same wake-up time every day. This "stimulus control" is rated at the highest level of evidence by the American Academy of Sleep Medicine (Morgenthaler et al., 2006). It is part of cognitive behavioral therapy for sleep, which in a meta-analysis of adults with long-term trouble sleeping cut the time to fall asleep by about 19 minutes compared with no treatment (Trauer et al., 2015).

3. A caffeine cut-off six hours before bed

Evidence: good. In a placebo-controlled trial, 400 mg of caffeine, roughly four cups of coffee, disrupted sleep whether it was taken at bedtime, three hours before or even six hours before (Drake et al., 2013). If you go to bed at 11 PM, that means no strong coffee after about 5 PM, and earlier is better.

4. Screens down an hour or two before bed

Evidence: good. Reading on a light-emitting e-reader instead of a printed book meant people took longer to fall asleep, felt less sleepy in the evening, made less melatonin and were less alert the next morning (Chang et al., 2015). In a newer sleep-laboratory study, stopping electronic devices two hours before bed shortened the time to fall asleep by about 6 minutes (Lu et al., 2026).

5. Write tomorrow's to-do list

Evidence: moderate. In a sleep-laboratory trial, young adults who spent five minutes writing a to-do list for the coming days fell asleep faster than those who wrote about tasks they had already finished, and the more specific the list, the faster they fell asleep (Scullin et al., 2018). It is one well-run study, not yet repeated, but it costs five minutes.

6. Mindfulness meditation

Evidence: good. In a randomized trial of older adults with disturbed sleep, a six-week mindfulness program improved sleep quality more than sleep-hygiene classes did (Black et al., 2015). A second trial found meditation programs reduced time awake at night and the racing, keyed-up feeling before sleep (Ong et al., 2014). This is a practice you build over weeks, not a one-night trick.

7. Progressive muscle relaxation

Evidence: moderate. Tense each muscle group for a few seconds, then release it, working from your feet to your face. A 2026 meta-analysis of 14 trials found it improved sleep quality overall, but the results varied a lot between trials and the benefit was clear only in adults under 55 (Li et al., 2026).

8. Regular exercise

Evidence: good. A meta-analysis of 66 studies found that both single sessions and regular exercise had small benefits for falling asleep and sleep quality (Kredlow et al., 2015). The effect is modest but it adds up with everything else.

9. A cool room and warm hands and feet

Evidence: moderate. Laboratory studies show that heat increases wakefulness and cuts deep and REM sleep more than moderate cool does (Okamoto-Mizuno et al., 2012). At the same time, warm hands and feet before lights-out go with falling asleep faster, because warm skin at the extremities is how the body sheds heat (Kräuchi, 2007). Cool room, warm socks.

10. Try to stay awake

Evidence: good, though it sounds odd. Lie in the dark with your eyes open and gently try to stay awake. This "paradoxical intention" takes away the pressure of trying to sleep, and a meta-analysis of 10 trials found it reduced sleep-related anxiety about performing and improved sleep (Jansson-Fröjmark et al., 2022).

Popular tricks with little or no evidence

• The "military method": widely shared online, but we found no published trial of it.
• The "cognitive shuffle" (picturing random unrelated objects): no published trial found.
• 4-7-8 breathing: only tested in small groups of people with specific health conditions, and mostly combined with other techniques, so its own effect is unknown.
• Slow breathing on its own: a randomized trial found it no better than a comparison routine for sleep (Savoie et al., 2020). It may still help you feel calmer.
