3/30 days challenge. How to quickly fall asleep? Sometimes, after going to bed, we stay many years or all the night without feeling asleep. I show one Technic that will help you to fall asleep during 30 secondes to 05 minutes. It's called the four seven height. It consists to breath seconds by your nose, cut your breath the seven next seconds and breath slowly by your mouth for eight seconds. Repeat doing this, until you fall asleep.
