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 issues like snoring and sleep apnea. Stomach sleeping may lead to neck and back pain due to spinal misalignment. Understanding the impact of sleep position can help individuals make informed choices for better rest and overall well-being.
