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 what your body feels like.
Whether you should sleep on your right or left side depends on the health problems you're facing. The left side may provide more benefits, especially for women who are pregnant or suffering from 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 the right side.
That said, sleeping on your back seems to be ideal for most people, followed by the left and then the right side. Just try to avoid sleeping on your stomach if you can, as this can put unnecessary pressure on your limbs, joints and spine. Christopher Winter, MD, medical director of the Sleep Medicine Center at Martha Jefferson Hospital in Charlottesville, Virginia, who spoke to CNN about the pros and cons of sleeping on your side. Sleeping on your back during this time can put additional pressure on the blood vessels supplying the uterus, reducing the supply of oxygen to the fetus.
Pregnant women and people with certain medical conditions may benefit from adopting certain sleeping positions. This sleeping position may be good for you if you snore, but if you have arthritis, you may wake up with pain. Sleeping on the left side may allow gravity to help with the process of moving waste through the ileocecal valve. You can try changing sleeping positions each week and recording how it feels each morning to stick to the sleeping position that makes you feel better mentally and physically.
A more recent attempt to associate personality traits with body positions during sleep emerged empty-handed. Loud or loud snoring can be a sign of sleep apnea, a condition that causes you to stop breathing and start breathing while you sleep due to airway obstructions. This position is also not a good option if you are prone to sleep apnea: shallow breathing or pauses in breathing that prevent a restful sleep. When people with GERD sleep on the left side, they experience fewer cases of heartburn than when they sleep on the right side or on their backs.
For healthy people who are not pregnant, there is no indication that sleeping on one side is more beneficial than on the other. People with heart failure should also avoid sleeping on their backs, as this puts pressure on the lungs and may contribute to symptoms of sleep apnea. A person has found the right position when he sleeps more deeply, wakes up more easily in the morning and feels more relaxed and alert throughout the day.
