Those who sleep on their backs
Sleeping on your back is the best position. This position is good for the spine. The only drawback is that you (or your partner) are more likely to snore.
Those who sleep on the side
The most common position is on the side. Unfortunately, constantly sleeping on one side increases the risk of pain in the arms and legs. In addition, sleeping on the right side can cause gastric reflux and impede digestion.
Those who sleep on their stomachs
This is the worst position. If you tend to sleep on your back, you probably experience neck and back pain.
