Amazing Benefits of Sleeping on Your Left Side
Here are some reasons for Sleeping on your left side:
- Facilitates lymphatic drainage from your brain
- Makes it easier for the heart to pump downhill
- Better elimination
- Supports healthy spleen function
- Encourages proper digestion
- Helps circulation back to the heart
- Helps bile flow more freely
The Lymph Drains toward the Left
The left side of the body is the dominant lymphatic side. Seventy-five percent of the body’s lymph fluid drains into the thoracic duct, which drains into the left side of the heart, left internal jugular vein, and left subclavian vein. Lymph fluid carrying proteins, glucose, other metabolites, and waste products is cleansed and then drained into the left side of the heart.
The small intestine dumps waste through the ileocecal valve (ICV) on the right side of the body into the beginning of the large intestine. The large intestine travels up the right side of the belly across the tummy, where it dumps waste into the descending colon on the left side.
Sleeping on the left side allows gravity to encourage the food waste to move more easily from the small intestine into the large intestine through the ICV.
During sleep on your left side, the waste moves more easily into the descending colon. With the help of gravity and a good night’s sleep on the left side, the descending colon is full of waste and ready to easily and completely eliminate in the morning.
One of the biggest players on the left side is the heart. If you sleep on your left side, the lymph drainage toward the heart will, again, be helped by gravity, taking some of the workload off of the heart as you sleep.
The aorta, the biggest artery in the body, leaves the top of the heart and arches to the left before it heads down into the abdomen. By sleeping on the left side, the heart is pumping its biggest payload downhill into the descending aorta.
Sleeping on the left also allows much of the intestines to hang away from the very thin-walled inferior vena cava (IVC), which brings venous blood back toward the heart. Interestingly, the IVC lies against the right side of the spine, so when you lie on the left, much of the viscera falls away from the IVC. Here again, gravity is just making the heart’s job a little easier.
The spleen, which is part of the lymphatic system, is also on the left. The spleen is much like a gigantic lymph node, except that in addition to filtering lymph, it also filters blood. When you lay on the left side, drainage back to the spleen is once again helped and made easier by gravity.
FACT; the lymph system drains all the cells in the body via movement and muscular contractions, rather than being pumped by the heart. Helping the lymph to drain to the spleen and heart with gravity is a good thing!
