Yoga Nidra or Yogic Sleep is another amazing type of meditation. Similar to the body scan we did a few weeks ago, this type of meditation allows you to focus your attention inwardly as you fall into the "in-between" state between awake and asleep. Studies have shown that a short Yoga Nidra practice is as restful on the body as an extra couple hours of sleep, making it a wonderful practice those days when you are feeling groggy but don't have time for a long nap or rest.
