Why Sleeping on Your Left Side Is Good for You
We here at Bright Side know first hand how important a good night's rest really is for our daily activities and energy. So we've decided to check this scientific theory, and we have compiled a list of six potential benefits that may be derived from taking a left-side sleeping position.
It improves the function of your lymphatic system
The lymphatic system plays a vital role in our body by removing waste and toxins from our systems. Experts say that the thoracic duct (which is the largest lymphatic vessel of the lymphatic system) is situated on our left side. That is why sleeping on your left side can help the body process waste materials more effectively. Since the lymphatic system also provides transportation of fats, proteins, and other important substances to your tissues, lying on your left side allows your cells to get these nutrients much faster.
It allows your spleen to do its job much better
The spleen is the largest organ in the lymphatic system and is also located on the left side of your body. When you sleep on your left side, your spleen works more efficiently. The main reason for this is gravity. It promotes the flow of blood to the spleen, allowing it to filter out impurities more quickly.
It promotes the proper elimination of waste products
The junction between the small intestine and the large intestine is situated in the left side of your body, in the area called the ileocecal valve. When you sleep on your left side, the gravitational forces make it easier for the waste products to move from the small intestine to the large intestine. This allows the colon to eliminate waste from your body more quickly.
It may reduce nighttime heartburn
If you suffer frequent heartburn, then it's a good idea to lie on your left side while catching some z's. In this position, your stomach will be situated below the cardiac sphincter that connects your esophagus to your stomach. The left-side sleeping position prevents stomach contents from coming back up into the esophagus.
It saves your liver from overloading
Since the liver is on the right side of the body, lying on your right side can put a strain on this organ. The left-side sleeping position, however, won't allow the toxins and other harmful substances to overload your liver.
It is good for your heart
The left side of the heart receives blood from the lungs and pumps it out to the body. Therefore, a left-sided sleeping position may help your heart to do its job more easily and efficiently. When you sleep on your left side, gravity facilitates the function of your circulatory system, especially your aorta and inferior vena cava, a large vein that carries de-oxygenated blood from the lower body to the heart and lies on the right side of your spine.
