The Insomniac's 3 A.M. Yoga Routine
Stiles says pointing your legs skyward improves circulation and lets the blood that's been pooling in your lower legs flow back into the rest of the body, including the brain. You'll feel the release in the backs of your legs.
How: Curl up on the floor in the fetal position with your legs tucked and your bottom close to the base of the wall. Roll onto your back and straighten your legs up toward the ceiling. Your torso should now be perpendicular to the wall, your legs resting comfortably against it. Stay here for five minutes.
