3. The Best Yoga Pose When You're Sad: Camel Why it works: "This yoga pose helps open up your lungs so you can breathe deeply, which increases oxygen levels in your blood. That elevates your mood and makes you feel better." How to do it: Kneel with legs shoulder-width apart, arch back, and reach hands behind you to grasp your heels. Push your hips forward so they're aligned with knees, and relax your head and neck [shown]. Hold 30 seconds, and remember to breathe deeply.
