Breathe With Me #3: Box Breathing

Part 3 of the Breathe with Me series

12 rounds of box breathing (sama vritti), with a ratio of inhale:retention:exhale: retention as 4:4:4:4.
This is for reducing stress and anxiety, improving sleep, and improving oxygen levels in the body.
If at any point you feel pressure in the lungs during the retention release from the exercise, breathe normally and join back in when you are ready. Hands can be held in chin mudra (thumb and index finger touching).
