Side sleeping is a popular sleep position where a person lies on their side, often with their legs slightly bent. This position can help reduce snoring and may alleviate some types of back pain. Many people find it comfortable and conducive to a good night's rest. Using a supportive pillow can enhance the benefits of side sleeping by keeping the head and neck aligned with the spine. Additionally, placing a pillow between the knees can help maintain proper hip alignment, making this position even more comfortable for those who prefer it.
