The main health risk associated with a sedentary lifestyle is an increased likelihood of developing chronic diseases, such as obesity, heart disease, and type 2 diabetes. Sedentary behavior, characterized by prolonged periods of sitting or inactivity, can negatively impact physical and mental health. It leads to decreased metabolic rate and muscle atrophy, contributing to weight gain and poor cardiovascular health. Encouraging regular physical activity and incorporating movement throughout the day are essential strategies to mitigate these risks and promote overall health and well-being.
