Combat insomnia
Easy-to-hold Iyengar yoga inversions, which send blood to the head, can help send you off to dreamland. The gentle Supported Standing Wide Leg Forward Bend is easy to relax into and will help still your thoughts.
How-to: Stand with hands on hips and feet approximately four feet apart, toes slightly turned in. Place a block or short stack of books on the floor in front of you. Breathe deeply; exhale, fold forward, and place hands on floor shoulder-distance apart with fingers spread. Lengthen spine forward and place crown of head on block so both head and neck are fully supported. Draw shoulders away from ears and hug elbows in. (If you feel a hamstring stretch, widen legs and raise block.) Close eyes; breathe slowly in and out through nose. Hold up to five minutes, then come out of pose slowly.
Note: If you have glaucoma or high blood pressure, stick to upright poses.

Cure a headache
A pounding head can keep you from falling asleep at night, but you don’t always have to pop a pill. This move, called Legs up the Wall, gently stretches the muscles in your neck (often the culprit of tension headaches) and relaxes you at the same time—a combo that can ease your ache in just a few minutes.
How-to: Sit on one end of a mat with your right hip touching a wall. Lean back, turn to lie flat on the mat, and extend your legs up the wall; your butt should be nearly touching the wall and your legs should be together. Put your hands on your belly or rest them on the mat above your head. Close your eyes, relax your jaw, and drop your chin slightly. Breathe deeply and slowly in this position for 3 to 10 minutes.

Soothe stress
Relaxing for one minute in Child’s Pose gives your mind and muscles a chance to escape everyday madness.
How-to: Sit back on heels with the insides of legs and feet touching. Lean forward, bowing torso over thighs and lowering forehead to mat. Extend arms forward, palms down. Relax into pose, widening knees or bending elbows a bit, as desired. Focus on breathing, taking four to eight counts for each inhale and exhale and relaxing deeper into pose with each exhale.
