A lack of physical activity contributes to various diseases, including obesity, type 2 diabetes, and cardiovascular conditions. Sedentary behavior decreases metabolic rates and can lead to weight gain and muscle weakness. It also negatively impacts mental health, increasing the risk of anxiety and depression. Insufficient exercise exacerbates these conditions by promoting inflammation and impairing insulin sensitivity. To mitigate these risks, it is essential to engage in regular physical activity, promoting cardiovascular health, maintaining a healthy weight, and enhancing overall well-being.
