According to Sheila Moore, a certified yoga teacher at Davidson College in Davidson, NC, you're probably not breathing correctly. Learning deep breathing techniques can help ensure your body gets all the oxygen it needs and doubles as a calming technique.
"Close your eyes and notice your breath from the moment you begin to inhale to the moment you complete the exhale. Begin to lengthen the inhale and the exhale. Follow your breath, become present, and start noticing how outside distractions and stressors begin to fade away," Moore says.
