To de-stress every night after work I do the following:
1) Chest openers--it is a yoga position whereby you place blocks or a bunch of pillows under your chest (about where the bra strap is for a woman) and let the head fall back as you lay on your back. Breathe deeply for 5 minutes.
2) Legs up the wall--this is a super healthy and easy yoga position! Lay on the floor and with your legs up the wall and back on the floor (body is in the shape of an L) breath deeply for 5 minutes.
3) I also meditate for anywhere for 10-20 minutes.
Then I have the energy and the focus to do anything! Without this reset button I am tired and sometimes cranky.
