Back sleeping, also known as supine sleeping, is a position where a person lies flat on their back with their arms at their sides or resting on their chest. This position is often recommended by healthcare professionals because it helps maintain the natural alignment of the spine, reducing the risk of back and neck pain. However, back sleeping may not be suitable for everyone. For instance, individuals with sleep apnea or snoring issues might find this position exacerbates their symptoms. Additionally, pregnant individuals are often advised to avoid back sleeping in later stages of pregnancy to prevent pressure on the vena cava and ensure proper blood flow.
