Having a bad day? Feel like your head is where your feet should be? When your head feels like it's about to explode, it's a good idea to change your perspective - literally.
Stand up and push your chair out of the way. With your knees bent, fold yourself in two at your waist. Relax your arms and let them dangle by your head. Feel the stress drain out of your head. Gently shake your head (as if saying no), then nod it (as if saying yes) - it's always good to end on a positive note.
Keeping your knees bent, return to standing. Move slowly so you don't get light headed and put your hand on your desk if you do.
If you don't feel like sticking your booty up in the air, just bend in half sitting down, putting your chest on your thighs and relax your head down.
