4-7-8 Sleep Method
This is shockingly simple, takes hardly any time, and can be done anywhere in five steps. Place the tip of your tongue against the ridge of tissue just behind your upper front teeth and keep it there through the entire exercise. This is followed by the five-step procedure listed below:
Exhale completely through your mouth, making a whoosh sound.
Close your mouth and inhale quietly through your nose to a mental count of four.
Hold your breath for a count of seven.
Exhale completely through your mouth, making a whoosh sound to a count of eight.
This is one breath. Now inhale again and repeat the cycle three more times for a total of four breaths.
The most important part of this process is holding your breath for eight seconds. This is because keeping the breath in will allow oxygen to fill your lungs and then circulate throughout the body. It is this that produces a relaxing effect in the body.
