Which Side Is Best to Sleep On Left or Right

It is no secret that the part of our day we spend sleeping is just as crucial for our health as the part when we are awake. Getting at least 7 hours of sleep each night is important for our overall well-being. That’s true, but there is not a lot of talk about the sleep position that we should follow. Grandmas say that you should sleep on your side, but which side is best to sleep on left or right? Let’s find out.

Which Side Is the Best and Why?

Do you want to improve your sleep quality and you are wondering which side is best to sleep on left or right? Years of research suggests that the best side to sleep on is your left one. The background science says that sleeping position directly affects the functioning of the brain’s waste clearing system aka the glymphatic system. The brain flushes toxins and other waste material through lymphatic vessels when you are asleep. And the left side of the body is the dominant lymphatic side.

Therefore, sleeping on the left side allows gravity to efficiently move waste through your glymphatic system and colon. Poor lymphatic circulation can lead to toxic build-up causing various health issues most common of which is heartburn. Other benefits include better brain function and reduced risk of neurological ailments like Alzheimer’s disease and Parkinson’s disease.

What about sleeping on the right side? Sleeping on the right can result in poor blood oxygen levels. This is because lying down on the right shifts the mediastinum towards the right lung. This reduces the lung volume and hence strains the cardiovascular system. Read more: Best Sleeping Positions for Digestion You Can Try This Night
