4. Diaphragmatic breathing activity
To do diaphragmatic breathing activities:
Lie on your back and either twist your knees over a cushion or sit in a seat.
Place one hand level against your chest and the other on your stomach.
Take moderate, full breaths through your nose, keeping the hand on your chest still as the hand on your stomach rises and falls with your breaths.
Next, breath gradually through tightened lips.
In the long run, you need to have the capacity to breathe in and out without your chest moving.
This procedure moderates your breathing and diminishes your oxygen needs as it fortifies your stomach.
