The Military Sleep Method: Does It Actually Work?

If you've spent any time on sleep-related corners of the internet, you've probably encountered the "military sleep method" — a technique allegedly used by the U.S. military to train soldiers to fall asleep in two minutes, anywhere, under any conditions. Videos about it rack up tens of millions of views. But does the science back it up, or is it another wellness trend that sounds more impressive than it is?

The answer, like most things in sleep science, is nuanced. The technique is real and has genuine merit — just not in the form that viral posts tend to describe it.

Where Did the Military Sleep Method Come From?

Despite its name, the method does not trace back to official U.S. military training manuals or documented field protocols. Its popularized form comes from a 1981 book by Lloyd Bud Winter titled Relax and Win: Championship Performance. Winter was a track and field coach who worked with Olympic athletes, and his book focused on using relaxation techniques to improve athletic performance and reduce pre-competition anxiety.

In the book, Winter described a relaxation routine he developed to help athletes — and, he claimed, military aviators — fall asleep under pressure. The military connection may have some basis (Winter reportedly worked with Navy pilots during World War II), but the specific claim that soldiers can fall asleep in exactly two minutes after six weeks of practice is Winter's assertion, not a finding from controlled sleep research.

The technique gained its viral popularity largely through a 2018 article by Business Insider, which was then picked up and amplified across social media. By the time it became a trend, the nuance of Winter's original work had mostly disappeared.

The Technique, Step by Step

Here is the method as commonly described, derived from Winter's book:

Step 1: Relax Your Face

Close your eyes and consciously release all tension in your face. Let your jaw drop slightly so your teeth are not touching. Relax the muscles around your eyes, forehead, and scalp. Let your tongue rest loosely in your mouth. This step is more important than it sounds — the face holds a significant amount of unconscious tension, and releasing it sends a signal to the nervous system to downshift.

Step 2: Drop Your Shoulders and Hands

Let your shoulders fall as far down as they will go. Imagine the tension draining out through your arms, past your elbows, down to your wrists, and out through your fingertips. Allow your dominant hand to go limp, then your non-dominant hand. If you notice you're still gripping, consciously release.

Step 3: Exhale and Relax Your Chest

Take a slow, deep breath, then exhale fully. As you breathe out, let your chest go heavy and sink into whatever surface you're lying on. Don't force breathing — just let it become slow and natural.

Step 4: Relax Your Legs

Move your attention down to your thighs. Consciously release the large muscle groups there. Then move to your calves, ankles, and feet. The goal is to feel like your legs are too heavy to lift.

Step 5: Clear Your Mind for 10 Seconds

With your body fully relaxed, spend 10 seconds holding one of three mental images: lying in a canoe on a calm lake with nothing but blue sky above you; lying in a black velvet hammock in a dark room; or simply repeating the phrase "don't think" slowly, over and over, whenever thoughts try to intrude.

That's the full sequence. In Winter's telling, with practice, you should be able to complete it and reach sleep onset within roughly two minutes.

What the Science Actually Says

The individual components of this method map closely onto techniques that are genuinely well-supported by sleep research — even if the specific 2-minute framing is not.

Progressive Muscle Relaxation (PMR)

PMR involves systematically tensing and releasing muscle groups throughout the body, and it has been studied extensively as a sleep intervention. A 2015 meta-analysis published in Sleep Medicine Reviews found that PMR significantly reduces sleep onset latency (the time it takes to fall asleep) and improves subjective sleep quality in people with insomnia. The military method skips the tensing phase and goes straight to release, which is a simplified version of the same concept.

Body Scanning

Bringing deliberate attention to each body region — as Steps 1 through 4 require — is a core component of mindfulness-based stress reduction (MBSR) and is associated with reduced cortisol levels and lower physiological arousal. When cortisol drops, your body becomes better able to transition into sleep. Research from Harvard Medical School has shown that body scan meditations activate the parasympathetic nervous system, which is the physiological opposite of the fight-or-flight state that keeps many insomniacs awake.

Mental Imagery

Step 5 — visualizing a calm scene — is essentially a lite version of cognitive imagery techniques used in therapy. Mental imagery occupies the same cognitive "channels" that anxious rumination uses, meaning that deliberately filling your mind with a peaceful image can crowd out intrusive thoughts. This is the same mechanism behind a technique called the cognitive shuffle (more on that below).

Why It Works for Some People

The military sleep method, when it works, is effective for a specific and identifiable reason: it addresses hyperarousal, which is one of the most common drivers of difficulty falling asleep.

Hyperarousal refers to a state of elevated physiological and cognitive activation — racing thoughts, muscle tension, a mind that won't stop reviewing the day's events or planning tomorrow. For people in this category, the body is essentially failing to downshift from its daytime alert state. A structured relaxation technique like Winter's method directly counters this by signaling to the nervous system that it is safe to reduce activation.

There is also a meaningful placebo component. Feeling like you have a plan — a specific set of steps to follow — reduces the performance anxiety that often surrounds sleep. Many insomniacs develop a secondary anxiety about sleep itself: the worry that they won't be able to fall asleep, which then becomes self-fulfilling. Having a ritual to execute gives the mind something to do other than monitor whether sleep is happening.

Why It Doesn't Work as Claimed

The 2-minute figure is the main problem. Sleep onset latency — how long it takes to fall asleep — is influenced by your homeostatic sleep drive (how long you've been awake), your circadian phase (whether your body clock thinks it's bedtime), your core body temperature, and your level of arousal. A relaxation technique can address the arousal piece, but it cannot override the others.

If you're trying to sleep at the wrong point in your circadian rhythm, or if you haven't built up enough sleep pressure because you napped, no amount of progressive muscle relaxation will put you under in two minutes. Similarly, if your insomnia has physiological causes — sleep apnea, restless leg syndrome, chronic pain — the method will have limited utility.

There are also no published, peer-reviewed studies specifically testing the military sleep method as described by Winter. The evidence supporting its components comes from research on PMR, mindfulness, and imagery techniques more broadly — not from controlled trials of Winter's exact protocol.

Who Benefits Most

The technique is most likely to help people whose sleep difficulties are driven by:

• Anxiety and overthinking at bedtime — the mental imagery component directly interrupts rumination.
• Physical tension — people who carry stress in their muscles (jaw clenching, shoulder tension) often find body-scan relaxation genuinely sleep-inducing.
• Conditioned arousal — people who have developed a habit of lying awake in bed, who associate the bed with wakefulness rather than sleep.

It is less likely to help people with circadian rhythm disorders, sleep apnea, or insomnia driven primarily by poor sleep hygiene (e.g., erratic schedules, excessive light exposure, alcohol use before bed).

Other Evidence-Based Alternatives

4-7-8 Breathing

Developed by Dr. Andrew Weil, this technique involves inhaling for 4 counts, holding for 7, and exhaling slowly for 8. The extended exhale activates the vagus nerve and promotes parasympathetic activation. It's particularly useful as a quick intervention for acute stress or anxiety at bedtime. Note that the ratios matter less than the extended exhale — any breathing pattern that makes your exhale longer than your inhale will have a calming effect.

Cognitive Shuffle

Developed by Dr. Luc Beaulieu-Prévost and popularized by researcher Luc Beaulieu and writer Michel Abou-Zeid, the cognitive shuffle asks you to imagine a random, unrelated sequence of objects or scenes — a banana, a lighthouse, a bicycle, a cloud. The randomness is the point: by presenting the brain with non-sequential, emotionally neutral images, you short-circuit the narrative processing that underlies anxious rumination. Some sleep researchers believe this mimics the hypnagogic imagery that naturally precedes sleep.

Paradoxical Intention

This technique, used in cognitive behavioral therapy for insomnia (CBT-I), involves deliberately trying to stay awake rather than trying to fall asleep. It sounds counterintuitive, but it works by removing the performance pressure around sleep. When you stop trying to force sleep, the anxiety that was preventing it often dissolves, and sleep follows naturally. It is one of the most effective single-session interventions in CBT-I for sleep onset insomnia.

The Bottom Line

The military sleep method is not a two-minute magic trick, and it doesn't have direct scientific validation as a protocol. But it is a useful, well-designed relaxation technique that borrows from legitimate sleep science — specifically progressive muscle relaxation and mental imagery. If you struggle with tension and overthinking at bedtime, practicing it consistently (the key word is consistently — Winter himself said six weeks) is likely to help.

Set realistic expectations. You are not training yourself to fall asleep in two minutes; you are training your nervous system to shift from alertness to calm more efficiently. That's a real and valuable skill, even if it takes longer than advertised.
