Well to babies it is, but to many of us it is not.
Many of us rely on breathing from our chest and as a consequence don’t get enough air into our lungs and oxygen into our bodies and suffer with pain caused by overusing certain muscles of the neck such as your scalenes.
Practice diaghragmatic breathing: lay on your back with a small pillow or block under your head. Place one hand on your chest and one on your belly. On an in breath allow the abdominals to relax and let your belly fill with air. As you breath out, fully expel all the air. Breathe in through the nose and out through the mouth. If you are doing it right the hand on your chest shouldn’t be moving much at all but your other hand will be moving as you expand your belly.
The benefits! More efficient oxygen and carbon dioxide exchange, more oxygen means more energy. It also reduces your blood pressure, helps you relax, increases your endorphins (helping with pain relief), increases circulation, improves digestion, improves performance in sports and gives the muscles in your neck some time off.
