Sedentary behavior has several negative health impacts, including increased risks of obesity, diabetes, cardiovascular diseases, and even early death. Being inactive can lead to poor muscle strength, reduced bone density, and mental health issues like anxiety and depression. To mitigate these impacts, it's essential to incorporate regular physical activity into one's routine, aiming for about 150 minutes of moderate-intensity exercise per week. Breaks from prolonged sitting can also help improve overall health outcomes.
