Excellent advice, but still, the quality of sleep that is achieved today is 20%, because there are distracting elements for the brain in their work at night:
1.- Crushing the ear.
2.- Obstruction of the superficial temporal artery (causes migraines)
3 - Irregular intensity of pressure
4 - The legs acquire uncomfortable postures.
5 - Shoulder crushed or twisted
6 - Internal tissue alteration
But do not worry, I have the solution, a bionic rest system, inspired by the Koala, see my post, in a few days.
Good post.
