Sleeping on your left side is thought to have the greatest benefits for your overall health. Even so, either side can offer benefits in terms of sleep apnea and relief from chronic low back pain. You don't have to stay with one side all night. Feel free to start on the left side and see how your body feels.
Whether you should sleep on your right or left side depends on the health problems you face. The left side may provide more benefits, especially for women who are pregnant or experiencing gastroesophageal reflux disease (GERD). People with these conditions may want to take special care to sleep on their left side. However, people with heart failure may experience discomfort on the left side and instead prefer to sleep on their right side.
Sleeping on your side helps prevent the airways from collapsing and can reduce snoring. When you rest on your back, your nostrils tend to close, which can cause you to snore. Sleeping on your left side can help open your airways naturally and make breathing easier. You can also find relief if you rest on your right side, but doctors think sleeping on your left side is more effective.
It is also the recommended sleeping position for people with sleep apnea.
