1. Yogic breathing.
This type of breathing maximizes your oxygen intake. Everyday Roots claims this type of breathing is used to treat sleep disorders and is wonderfully relaxing. To do it, breath in slowly and deeply through your nose. Pause for a moment when your lungs are full and you can’t bring in anymore air. Then slowly, with your tongue pressing on the roof of your closed mouth, push the air out from the back of your throat. It should have the soothing sound of crashing waves.
