In addition to digestion, sleeping posture may also affect breathing and circulation. Some people who sleep on their backs experience snoring or interrupted breathing during sleep. Side sleeping is often recommended because it may help keep airways more open.
However, sleeping on only one side every night for long periods may sometimes contribute to shoulder discomfort, arm numbness, or hip stiffness. Doctors recommend using supportive pillows and changing positions naturally during sleep whenever possible.
Pregnant women are also commonly encouraged to sleep on the left side, especially during later stages of pregnancy. This position may help improve blood flow and reduce pressure on important blood vessels. Many maternity specialists consider left-side sleeping one of the most comfortable and supportive positions during pregnancy.
Still, experts emphasize that there is no single “perfect” sleeping position for everyone. Each person has unique health conditions, body structure, and comfort preferences. For some individuals, sleeping on the right side may not cause any noticeable issues at all.
