Potential risks of insufficient physical activity include various health concerns. A sedentary lifestyle may lead to weight gain due to decreased calorie expenditure. Inactivity elevates the risk of chronic diseases such as diabetes, heart disease, and certain cancers. Additionally, muscle mass decreases, leading to weakness and lower metabolic rates. Mental health can also suffer, resulting in increased anxiety and depression. Engaging in regular physical activity is essential not only for maintaining physical fitness but also for promoting overall well-being.
