We all know that duration of sleep is critical for mental and physical wellbeing, but it turns out that sleep position may be another important factor in the quest for optimum health.

Specifically, a small body of research suggests that, for many people, sleeping on the left side may be the ticket to better health and better sleep. The theory stems from Ayurveda, a holistic approach to health and medicine that originated in India centuries ago.

So why all the fuss about sleeping on the left side? It turns out it may be good for our digestion, our backs, and even our hearts due to the positions of different organs. Here are six potential benefits that may be derived from catching some Zzzs while lying on your left side.

1. It bolsters the lymphatic system.

According to Ayurvedic medicine, sleeping on your left side allows your body to better filter lymph fluid and waste via the lymph nodes on the left side of our body is the dominant lymphatic side. Western research has also found that sleeping on the left side can help the body process waste materials from the brain. In contrast, sleeping on your right side can decrease the lymphatic system’s efficiency.

2. It may improve digestion.

When it comes to digestion, sleeping on the left side may be preferable to the right due to the simple matter of gravity. Specifically, lying on the left side allows food waste to easily move from the large intestine into the descending colon (meaning you’re more likely to have a bowel movement upon waking). Sleeping on the left side also allows the stomach and pancreas to hang naturally (our stomach lies on the left side of the body), which can keep the development of pancreatic enzymes and other digestive processes humming.
