Sleep position refers to the way a person lies down while sleeping. Common positions include back sleeping, side sleeping, and stomach sleeping. Each position can affect comfort, sleep quality, and even health. For example, side sleeping is often recommended for pregnant individuals, while back sleeping may help reduce acid reflux. The choice of sleep position can influence factors like spinal alignment and snoring. Stomach sleeping may lead to neck and back pain due to the strain it places on the spine. Understanding the impact of different sleep positions can help individuals make informed choices for better rest.
