After a long day of work, nothing's better than crawling into bed and having a peaceful snooze.
But, drifting off to sleep isn't always easy, and while you may be craving a good night's rest, you end up tossing and turning instead.
Nobody knows this to be more true than the brave members of the military, who are lucky to get a few hours of shut eye at a time.
During the Second World War, some soldiers had been making critical mistakes due to their lack of sleep, but since then, they have created just the trick that ensures you go out like a light in only two minutes.
According to Medium, The U.S. Navy Pre-Flight School came up with a scientific method that allows anyone to fall asleep in any conditions, day or night.
And lucky for us, the book Relax and Win: Championship Performance tells us how to do just that.
After six weeks of training, the school found a 96% rate among the experiment's participants, and there is only six easy steps.
While it's the optimal choice of falling asleep entirely stretched out, these pilots were trained to fall asleep while sitting in a chair.
But, as long as their feet were flat on the floor and had their hands go limp on their lap.
The first thing an individual needs to do is relax all 43 muscles in your face.
This includes your tongue, jaw, and the muscles around your sockets. Don't forget to close your eyes.
Once the muscles in your face have been relaxed, let your shoulders drop down as low as they can.
Once you take a few deep breaths to lessen any tension you may have, send your arms limp, making your dominant side go first.
Start with your bicep before moving on to your forearms, hands and fingers. If it doesn't feel like you're sinking into yourself, tense your arms and try it again.
Once you're satisfied, repeat the technique on your other arm.
After you've relaxed your upper body, it's time to focus on your legs.
Like your arms, start one at a time, beginning with your thighs, calf muscles and then all the way down to your ankle and foot.
By now, every muscle in your body should be entirely relaxed.
For a good night's rest, the final step can be argued as the most difficult of all - clearing your mind.
Take 10 seconds to just clear your mind and forget about the trials and tribulations of the day.
If you don't, you risk your muscles involuntary contracting, which will cause unwanted movement.
If you find yourself unable to clear your mind for 10 seconds, the book's author Lloyd Bud Winter recommends you imagine a canoe in a lake, being snuggled in a black velvet hammock in a pitch-black room, or repeat in your mind "don't think, don't think, don't think, etc."
Once your mind is completely still, you'll quickly drift off to sleep.
