The position that we take while
sleeping has a significant influence on our digestion. In ancient times, the
monks used to lie down after each meal just for ten minutes to improve the
digestive process.
Moreover, the most ancient tradition
of oriental medicine (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.
