Moreover, the most ancient tradition of ayurvedic as well as the Indian alternative medicine suggest sleeping on the left side.
The reason is very simple. The left side of the body is the dominant lymphatic side. The majority of the body’s lymph fluid drains into the thoracic duct, located on the left side. Along the way, lymph fluid carrying proteins, glucose and other metabolites and waste products is purified by lymph nodes and is then drained into the left side of the heart.
