What's a Good Breathing Exercise to Help Me Sleep?

So, when we get in bed at the end of the day often times our mind is racing, racing, racing. Number 1 thing I hear is I can't turn off my brain. So, what I have people do now, is a breathing exercise, it's called diaphragmatic breathing. And all it is, is breathing in very very deeply, in through your stomach, up through your chest, holding it for six seconds, and then slowly releasing it.

Doing this about six to eight times in a row can have a dramatic effect, not only in calming you down but helping you sleep.
