Breathe away stress in 90 seconds or less. Lie down on your back with your arms by your side. And now start breathing with an Ujjayi breath where you slightly constrict your throat and make an ocean wave like sound on every inhale and every exhale. Breathing in through your nose for eight seconds, out through your nose for eight seconds, slowly keeping that steady, smooth rhythm. It reduces stress, improves whole body oxygenation, it can even reduce your blood pressure. Now you may see those books on my belly. This is going to train your diaphragmatic muscles to get strong. It also naturally slows your breathing down and it helps you know that you're breathing diaphragmatically.
