Yoga is intended to help with both physical and mental health so I don't think too many people are surprised to hear that yoga can help improve your mood. Whether you're feeling a little depressed, bored, stressed out, or even insecure before a big date or important event there are poses that will help you combat those emotions and help you get into a more positive frame of mind. And there's real physical evidence to back up the effects -- by holding your body in certain positions you can stimulate glands that release mood altering chemicals. Move #3 here I come!
