If you are feeling more anxious as a result of the pandemic why not try this excellent book. It is very readable – interspersed with exercises to help reduce stress, live in the moment and relax. As you go further into the book there are sections on finding harmony in the relationships in your life, finding time for meditation and letting go of the past. I thoroughly recommend it to everyone as it has something to offer on those days when you may not feel like physical exercise – perhaps you may be a bit down in the dumps, and it brings some perspective to your circumstances. Sadness, fear and anxiety all lead to stress and a physical tightness in the body. In turn this can lead to reduced breathing capacity denying your body and brain the vital life source (prana) which comes from oxygen. The result is illness and disease and we want to avoid that as much as possible.
If your breathing is in any way restricted, to that degree, so is your life.
