Chronic illness can severely impact physical activity levels, often leading to reduced mobility, fatigue, and diminished motivation. Individuals managing chronic conditions like arthritis or heart disease may find it challenging to maintain regular exercise routines due to pain or physical limitations. These barriers can contribute to a sedentary lifestyle, exacerbating health challenges and increasing the risk of further complications. Thus, tailored exercise programs and support systems are essential in helping individuals with chronic illnesses engage in physical activity and improve their overall quality of life.
