The supine position is a body posture where an individual lies flat on their back, facing upward. This position is commonly used in various medical examinations, treatments, and during sleep. It allows for easy access to the front of the body, making it ideal for procedures like surgery or physical examinations. In addition to medical uses, the supine position is also beneficial for relaxation and certain exercises, such as yoga and stretching. It helps to align the spine and can reduce pressure on the back, promoting comfort and stability during rest or physical activity.
