Lifestyle choices, such as diet, exercise, and smoking habits, significantly impact bone density. A diet rich in essential nutrients like calcium and vitamin D helps build and maintain strong bones. Regular weight-bearing and strength-training exercises stimulate bone formation, while a sedentary lifestyle can lead to bone loss. Additionally, habits such as excessive alcohol consumption and smoking can lead to osteoporosis and other conditions affecting bone health. Therefore, making conscious lifestyle choices that support bone density is crucial for long-term skeletal health.
