Before the inversions – actually before all kinds of Asanas – we should not eat. Not even a little bit. Why? Because our body starts to digest. Vata, the air element, is responsible for all kind of movement in the body. And when we start to practice while the air is working, we bring it out of balance. It cannot work properly anymore. So we have to wait to practice until the digestion has finished.
Sleeping also disturbs the digestion. It is recommended to have some movement after food for minimum half an hour. If we do a siesta after lunch or we go to bed soon after dinner, we should lay down on the left side so that the right nostril stays open and the HA energy continuous to work. When we sleep on the other side, the digestion will not work properly, the food stays in the body too long and cannot really be absorbed. By sleeping on the left side we digest and sleep good.
