If you prefer to read rather than watch, here are the instructions for using this technique:
1. Lie down and set an alarm for 10 minutes
2. Inhale deeply to the count of four, hold your breath to the count of four and exhale deeply to the count of eight.
3. While you are holding your breath, focus on how your body feels. Notice the sensations, such as the feeling of your heart beating.
4. Continue doing this until you alarm goes off.
It is a fantastic technique for reducing stress and anxiety – and it has a cumulative effect on your nervous system.
I hope it is helpful to someone.
