Low breathing
Try the following: Stand quietly upright with feet shoulder-width apart. Hands in front of your navel, with fingers interlocked, as in prayer. Keep those fingers that way with the exception of your pinky and ring fingers. You stretch these so that fingertips on inside of fingers are against each other. Middle finger is still in prayer position. Now gently breathe in to your pelvic floor. Do that several times for as long as it feels comfortable.
In one day, repeat this as often as you want/can.
Deep breathing is very healing. Gives a clear message to your cells: there is enough oxygen so don’t worry 😀 this can shut down your stress impulse
