It can be helpful to continually release built up tension in your body.
If you’re feeling overwhelmed go into your bathroom, close the door, and shake! Really shake, loose wrists and fingers, bounce up and down on your heels. Let out some good audible sighs and imagine shaking off all your fears etc. letting them go. Make some crazy faces in the mirror. Dance around. Really get into the feeling of “letting go” of pent up stress.
You could have some upbeat music playing. Do this for a couple of minutes, pause and just feel how good it feels! Excellent to teach to kids.
