A sedentary lifestyle can drastically affect bone density negatively. Physical inactivity leads to a decrease in mechanical stress on bones, which is essential for maintaining bone strength and density. Weight-bearing exercises stimulate bone formation and help prevent conditions like osteoporosis. Research demonstrates that individuals who engage in regular physical activity retain higher bone density than those who lead sedentary lifestyles. Additionally, inactivity can contribute to hormonal imbalances that affect bone remodeling. Consequently, incorporating regular activity into one's routine is vital for preserving and enhancing bone health, especially as one ages.
