A sedentary lifestyle contributes to chronic diseases such as obesity, type 2 diabetes, and cardiovascular diseases. Lack of physical activity leads to weight gain and a decreased rate of metabolism, increasing the risk of insulin resistance and metabolic syndrome. Additionally, prolonged sitting can contribute to muscle atrophy and decreased cardiovascular health. Engaging in regular physical activity can help mitigate these risks by improving blood circulation, strengthening muscles, and enhancing overall mental and physical well-being.
