Today Health published a series of yoga poses that a yoga instructor says may help improve sleep.

You might think that a vigorous physical practice would be the best approach — beating your body into submission until you rest out of sheer exhaustion. But that would be incorrect. A vigorous yoga practice is a wonderful way to get you going in the morning, or even to give yourself a boost in the afternoon. However, intense activity less than 4 hours before bedtime can actually hinder your ability to wind down. In fact, it may leave you feeling wired, which is a sign that you’re overtired.
