Okay, here is something that has helped me a great deal. It’s just a simple relaxation technique/ mindfulness practice.
Get comfortable lying down, I find that is the best. But you can do it seated or standing any way you wish.
Start by tightening every muscle in your body. Clench your jaw, squint your eyes, flex your shoulders and your back, your buttocks, stomach, thighs, calves feet. Tense every muscle in your body. Hold it for 10 seconds or whatever feels comfortable, and release it. Shake out your arms and legs and let the stress go. Take several deep, deep breaths and let the energy flow.
Repeat this as many times as it takes to cause a shift from beta to alpha waves in your brain. You’ll feel the shift
Cheers
