How to sleep in 10 seconds?
The military method
Relax your entire face, including the muscles inside your mouth.
Drop your shoulders to release the tension and let your hands drop to the side of your body.
Exhale, relaxing your chest.
Relax your legs, thighs, and calves.
Clear your mind for 10 seconds by imagining a relaxing scene.
If this doesn’t work, try saying the words “don’t think” over and over for 10 seconds.
Within 10 seconds, you should fall asleep!
If this doesn’t work for you, you may need to work on the foundations of the military method: breathing and muscle relaxation.
