I find this routine to be effective at times (I asked ChatGPT to spell out the details and it supplied this):
The technique involves inhaling through your nose for a count of 4, holding your breath for a count of 7, and then exhaling through your mouth for a count of 8. This is repeated for several rounds, usually four to eight times, depending on your comfort level.
The idea behind this technique is that by slowing down your breathing and focusing on your breath, you can reduce anxiety and promote relaxation. It has been popularized by Dr. Andrew Weil, a well-known integrative medicine physician.
It's worth noting that while many people find this technique helpful, it may not work for everyone. If you have any medical conditions or concerns about your breathing, it's always a good idea to consult with your healthcare provider before trying any new relaxation techniques.
