"A decline in physical activity may come with age due to muscle loss, joint stiffness, fear of injury, worsening illness, or depression. Residents who spend too much time in bed or a chair may lose the ability to perform activities of daily living, like eating, dressing, or getting to the bathroom."
Why is this important?: "Staying in a bed or chair affects the resident in many ways. Unused muscles get weaker. It becomes difficult to participate in physical and social activities. Sleep quality can suffer. The risk of heart disease, stroke, diabetes, or blood clots can increase. Depression and anxiety can worsen. Staying in one position, and constant pressure on the skin can increase the chance of pressure sores. It is important for residents to be as active as possible."
