Eight ways to feel healthy and happy in March

Tired of tossing and turning when you go to bed? Then try the "tension tamer," a new relaxation technique from Walter Reed National Military Medical Centre in Bethesda, Maryland, that's proven to help people drift off more quickly. Here's how: Get cozy. Close your eyes and focus on slowly inhaling and exhaling. Then let your mind wander to the most restful place you've ever been. (Maybe it's that sandy beach you visited last summer, a cottage dock or a quiet park.) Picture it while breathing deeply for 10 minutes — if you can last that long before dozing off!

Proof it works: In the study, it took only four nights for people to fall asleep faster, sleep more soundly and even feel perkier in the morning. —Laura Fader
