The most important trick to getting a good night's sleep

What if there were a simple, all-natural, non-pharmaceutical way to help you fall asleep — or fall back asleep? Unlike the New Math that none of us are smart enough to do, this sleep technique named with a sequence of numbers – 4-7-8 Breath — is simple: breathe in for 4 seconds; hold that breath for 7 seconds; then exhale that breath for 8 seconds. Taking in that extra oxygen and getting rid of the carbon dioxide slows your heart down and quickly calms your body. It’s just a fancy way of saying mindful breathing, but if you’re already confused, let Dr. Andrew Weil demonstrate how to do it.
