4. Support the lymphatic system
The lymphatic system is a network of vessels that carry clear fluids called lymph. This system plays an important role in immune function and lymphatic movement throughout the body. Lymph helps to carry away toxins and other waste products. Therefore, when the lymphatic system is blocked, your health will be in trouble.
Lymph escapes to the left through the thoracic canal so a sleeping position on the left facilitates gravity to support the lymphatic system’s waste filtering function.
