In care homes, older adults who are frail and sedentary are at increased risk of negative health effects due to their lack of physical activity. Here are some of the ways it can affect them:

1. Increased risk of chronic diseases: Physical inactivity is a well-established risk factor for chronic diseases such as heart disease, stroke, type 2 diabetes, and some types of cancer. In care homes, older adults who are frail and sedentary are at increased risk of developing these conditions, which can have a significant impact on their quality of life and ability to function independently.
2. Weakened muscles and bones: Regular physical activity is important for maintaining muscle mass and bone density, and a lack of physical activity can lead to muscle weakness and a loss of bone density. This can be especially problematic for frail older adults who are at higher risk of falls and fractures, as it can reduce their ability to perform everyday activities and increase their dependence on others.
3. Decreased mobility and independence: Inactivity can lead to decreased mobility and flexibility, making it harder for frail older adults to perform everyday tasks and increasing their dependence on others. This can have a significant impact on their quality of life and sense of independence.
4. Cognitive decline: Studies have found that sedentary behaviour is associated with cognitive decline in older adults, and that regular physical activity can have a positive impact on cognitive function. Frail older adults who live sedentary lives in care homes may be at increased risk of cognitive decline, which can have a significant impact on their quality of life and ability to function independently.
5. Mental health problems: Physical inactivity can also have a negative impact on mental health, leading to feelings of depression and anxiety. This can be especially problematic for frail older adults who may already be struggling with cognitive or emotional issues, as it can further reduce their quality of life and increase their dependence on others.

To address these negative health impacts, care homes should encourage and support physical activity among their residents. This may involve providing structured exercise programmes, creating safe and accessible spaces for physical activity, and encouraging residents to be more active throughout the day.
