Want to Fall Asleep Faster? Military Pilots Use This Hack to Sleep Anywhere in 2 Minutes or Less

Obviously, if you're in your bed, this is a non-issue. But if you're out and about, get into the most comfortable position that's feasible (i.e., lean your seat back if you're in your car; find the most comfortable chair in the conference room if you're napping at work).

2. Relax your face.

This is key to the whole thing. You have 43 muscles in your face, and they're a big part of how your body knows whether you're stressed. When you fully relax your face, you send a physiological signal to your body that all is well. It's safe to sleep.

So close your eyes and relax your whole face: forehead, cheeks, tongue, and jaw. Let it all go slack. You'll notice as you do this that your breathing naturally starts to deepen and slow.

Now make sure your eyes are fully relaxed. You have six muscles in your eye sockets; feel them all go limp.

3. Drop your shoulders.

Let them get heavy, and then let them go completely, as if they were falling down toward your feet. Let the back of your neck relax and go limp. Take a deep breath and let it out slowly, releasing any remaining tension there (most people store most tension in their shoulders, necks, and jaws).

Now your arms: Feel them get heavy and relax, starting with your dominant side. If you're right-handed, start with your right bicep and feel it relax. If it's not, tense it fully and then let it go slack. Repeat the process with your hands.

4. Let your legs go limp.

Feel your right quad sinking down, getting heavier and heavier. Next your right calf, ankle, and foot. Repeat on the other side.

5. Clear your mind for 10 seconds.

Winter has some tips for what to "think" of instead--and remember, you're holding this for 10 seconds straight:

First, we want you to fantasize that it is a warm spring day and you are lying in the bottom of a canoe on a very serene lake. You are looking up at a blue sky with lazy, floating clouds. Do not allow any other thought to creep in. Just concentrate on this picture and keep foreign thoughts out, particularly thoughts with any movement or motion involved. Hold this picture and enjoy it for 10 seconds.

And that's it. When you have a fully relaxed body and a mind that's still for 10-plus seconds, you will fall asleep, period.

Remember that the pilots practiced the method over and over, and 96 percent of them achieved success after six weeks of practice. These weeks of practice are a worthwhile investment, because once you have it down, you can nap and sleep anywhere, which will dramatically improve your quality of life.
