The Navy SEAL Sleep Method: How to Do It, Where It Came From and Whether It Really Works

Where the "Navy SEAL" sleep method comes from

No record shows Navy SEALs inventing this technique. It was written down by Lloyd "Bud" Winter, a San Jose State track coach whose sprinters set 37 world records. During World War II, Winter worked at the Navy's preflight school in Del Monte, California, where cadets were struggling to sleep between training and combat stress. With a psychology professor, he built a relaxation program for pilots.

Winter described that program in his 1981 book Relax and Win: Championship Performance, reissued in 2012. He wrote that after six weeks of practice, 96% of the pilots could fall asleep within two minutes, day or night, even with simulated gunfire playing. That number is repeated online as if it were a clinical result. It is a coach's account of an unpublished wartime program with no control group, no published data and no replication, so judge the technique on its components, not the statistic. The technique went viral on TikTok in 2022, which is when "military sleep method" and "Navy SEAL sleep method" became search terms.

The military sleep method, step by step

Lie on your back if you can (your side works too). Close your eyes. The sequence takes about two minutes once you know it.

1. Relax your face

Let your forehead go smooth. Unclench your jaw and let your mouth fall slightly open. Let your tongue rest heavy in the bottom of your mouth. Relax the muscles around your eyes and let them sink back into their sockets. Winter emphasized the face because a tense jaw and forehead signal alertness to the rest of the body.

2. Drop your shoulders and arms

Let your shoulders fall away from your ears. Release one arm at a time: upper arm, forearm, hand, fingers. Imagine each arm sinking into the mattress. If you cannot feel the difference, tense the muscle for five seconds first, then let go.

3. Breathe out and let your chest go

Take one slow breath in and a longer breath out, letting your chest soften on the exhale. Do not force deep breathing; just make the exhale slightly longer than the inhale and let your ribs settle.

4. Relax your legs

Work down from your hips: thighs, calves, ankles, feet. Let each part feel heavy and warm. Some people find it easier to imagine the mattress rising to hold each leg.

5. Clear your mind for ten seconds

This is the step most people skip and the one that matters most for a busy mind. Winter offered three options: picture yourself lying in a canoe on a calm lake with nothing above you but blue sky; picture yourself in a black velvet hammock in a pitch-black room; or, if images will not stay put, silently repeat "don't think, don't think" for ten seconds.

If you are still awake, do not restart from the top or check the clock. Stay with the image or return to the slow exhale.

Step, action and reason at a glance

Why it may work

Progressive muscle relaxation

Steps one through four are a compressed form of progressive muscle relaxation (PMR), developed by Edmund Jacobson in the 1920s and now a standard component of behavioral insomnia treatment. A 2026 meta-analysis of 14 randomized trials with 957 adults found PMR significantly improved sleep quality versus control, with a large pooled effect, though heterogeneity was high and the benefit was clearest in adults under 55. The American Academy of Sleep Medicine lists relaxation training within its recommended treatments for chronic insomnia.

A shift toward the parasympathetic system

You cannot fall asleep while the sympathetic "fight or flight" system is dominant. Slow breathing with a long exhale is one of the fastest ways to tip the balance. A 2026 systematic review in Sleep Medicine Reviews covering nine studies and 457 participants found slow breathing (ten breaths per minute or fewer) before bed improved self-reported sleep duration and quality, with heart-rate-variability data confirming an autonomic shift, though sleep-lab results were mixed. Step three is a small dose of this; the 4-7-8 variation below is a larger one.

Cognitive distraction

The ten seconds of imagery has the most direct evidence for a racing mind. In a controlled study at Oxford, Allison Harvey and Suzanna Payne gave 41 people with insomnia one of three instructions: distract with a specific pleasant image, distract in general, or nothing. The imagery group fell asleep faster and reported less distressing pre-sleep thinking. A vivid, specific image occupies enough "cognitive space" that worries cannot re-enter. Winter's canoe and hammock are exactly this kind of image.

Realistic expectations

The two-minute promise sells the method and is its least reliable part. Even Winter's pilots practiced for six weeks.

• Week one: you feel more relaxed but still take a normal 15 to 25 minutes to fall asleep, and holding the image for ten seconds is hard.
• Weeks two to four: the sequence becomes automatic and your body starts to associate it with sleep. This conditioning is where most of the benefit lives.
• After a month: regular practitioners often report falling asleep noticeably faster and using the method to get back to sleep after night waking.

It works best for sleep-onset trouble driven by tension or an overactive mind. It does poorly against caffeine, alcohol, a warm bedroom, screens in bed, an irregular schedule, pain or a medical sleep disorder. If you snore loudly, wake gasping, or struggle to sleep three or more nights a week for three months, see a doctor. Fix the basics in why can't you sleep first, keep a fixed wake time (the 3-2-1 sleep rule is a simple evening framework), and layer the military method on top.

Variations worth trying

4-7-8 breathing

Popularized by Andrew Weil: inhale through the nose for four counts, hold for seven, exhale through the mouth for eight, four times. It slots into step three. A 2022 study in Physiological Reports found a session of 4-7-8 breathing lowered heart rate and systolic blood pressure and raised the high-frequency component of heart-rate variability, a parasympathetic marker, in healthy young adults. Evidence that it shortens time to sleep specifically is thin, but the physiology is sound.

Body scan

Instead of actively relaxing each region, place attention on each body part in turn, toes to scalp, noticing sensation without trying to change it. This mindfulness version suits people who find "trying to relax" makes them tense. It takes five to ten minutes but is gentler.
