This breathing technique will help you tap into the part of the brain called the insula, which is associated with cravings as well as moral intuition, creativity and empathy, says Tara Stiles, yoga instructor and author of the upcoming Yoga Cures. "I find that it really helps calm everything down, starting with the mind and continuing down through the rest of the body."
How: Sit cross-legged with your back supported either by the headboard or the back of the couch. Press your ring finger over your left nostril and inhale four counts through your right nostril. Then, close off your right nostril with your thumb so both sides of your nose are closed. Hold all the air for four counts. Release your ring finger and let all the air out of your left nostril for four counts. Reverse this pattern by inhaling through the left nostril, holding both closed and then exhaling out the right. Repeat this breathing pattern for three to five minutes—or until you're more interested in sweet dreams than sweet treats.
