Prolonged bed rest refers to an extended period of time spent lying in bed, often due to medical conditions, recovery from surgery, or severe illness. While it may be necessary for healing, it can lead to various complications, such as muscle weakness, joint stiffness, and decreased cardiovascular fitness. Additionally, prolonged bed rest can increase the risk of developing pressure ulcers, blood clots, and respiratory issues. Healthcare providers often recommend gradual movement and physical therapy to mitigate these risks and promote recovery, ensuring that patients regain strength and mobility as soon as possible.
