This method was used by the US Military to train soldiers
to sleep in war zones. It was copied verbatim from https://bigthink.com/neuropsych/military-method-sleep.
Many people find success with this method. If it doesn't help, make
an appointment to discuss other options.
When your sleeping quarters are located in the middle of loud, stressful, and dangerous conditions, you might find it hard to nod off. Given that “loud, stressful, and dangerous” is kind of the U.S. Army’s thing, they needed a method to help their soldiers sleep. This technique — the “military method” — was first recorded in the 1981 book Relax and Win: Championship Performance by Olympic coach Lloyd Bud Winter.
Winter spent the years after World War II talking to members of the U.S. Army Air Corps and he learned about a little-known technique they used to relax their pilots. It was said that pilots in the Pre-Flight School who used the military method were able to fall asleep within 10 minutes. Within only six weeks, 96% of pilots using the method were reportedly able to fall asleep within this timeframe — even with gunfire in the background.
So, what is this magic technique? Below we lay out the military method’s steps to a good night’s sleep. It’s deliberately designed to be easy and efficient, so anyone can start tonight.
Relax your face. Focus on your forehead, your eyes, your cheeks, your jaw, and so on. Feel the tension held in them and consciously push it away.
Drop your shoulders. Let your arms flop down and your shoulders relax. Imagine there is a soft, warm wind gently pushing your arms down.
Take a deep breath. Slowly inhale and let it out. As you do so, focus on how it relaxes your stomach. Don’t try to hold your stomach in; let it all out.
Relax your legs. The warm wind is back, and this time it’s gently easing your legs down. Let your legs sink into the bed or the floor. They are leaden, and the bed is soft.
Clear your mind. There are a few ways to do this. For instance, try to visualize some calming images, like lying by a flowing river or staring at the clouds. If that doesn’t work, try saying the words “don’t think” over and over for about 10 seconds. If you get distracted, don’t get angry; just pull your mind back to one of those two techniques.
