Stress can disrupt sleep. Belly breathing, a technique that uses the diaphragm instead of shallow chest breathing, is recommended to relax and fall asleep. Lie down, place one hand on your belly and breathe in through your nose so your belly rises. Hold for a few seconds, exhale slowly through your mouth as your belly falls. Repeat for a few minutes. Belly breathing activates the relaxation response, slows heart rate and blood pressure, and reduces stress hormones. It should be incorporated into a bedtime routine for better sleep.
