Lie down or sit upright. If seated, relax your arms and rest your hands in your lap or on your thighs. Take a deep breath and let it out with a sigh, relaxing your face and jaw. Now breathe in and fill your lungs as much as possible to the count of 4, hold the breath to the count of 7, and exhale to the count of 8. It can be helpful to use the ocean breathing style during this exercise. Repeat this cycle at least 4 times if possible, or longer. Finish with a deeper in-breath and let it out again with a sigh. Please note: If you are pregnant, don't hold your breath for longer than 2 counts.
