A sedentary lifestyle can have several detrimental effects on health, including increased risks of obesity, heart disease, and type 2 diabetes. Prolonged inactivity can weaken muscles, reduce flexibility, and contribute to joint issues. Additionally, it may lead to mental health challenges, such as depression and anxiety. Insufficient movement restricts blood flow and encourages metabolic slowdown, impacting energy and overall well-being. To combat these effects, regular physical activity is vital, promoting better health and enhancing both physical and mental fitness.
