Recently a Harvard graduate doctor Andrew (Andrew Weil) shared a method called “4-7-8 breathing method” to help sleep, without drugs or equipment, as long as you follow this method, you will be able to fall asleep in 60 seconds! Method: Just use your nose to inhale for 4 seconds, hold your breath for 7 seconds, and then finally exhale for 8 seconds, do 3 cycles after you can feel sleepy, at first do not be familiar with no sleepiness, but as long as you insist on doing it 2 times a day, continue for 6-8 weeks after the habit, then you can quickly fall asleep peacefully within 60 seconds! This trick is mainly from the ancient Indian breathing regulation method, through deep inhalation and exhalation to let more oxygen into the lungs and flow in it, so that the sympathetic nerve relaxation, help reduce stress, so that people really calm down and relax the body to sleep.
