As we age, our posture may change and sometimes result in a hunched back, known as kyphosis. Common causes include bone density loss due to osteoporosis, disk shrinkage, and muscle loss. To prevent a hunched back, it's crucial to keep your back, chest, and core muscles strong through exercises. Pay attention to your posture during daily activities, such as sitting up straight while watching TV, and take breaks from activities that promote poor posture. Physical therapy can also help by providing specific exercises and postural advice. Doctors may recommend medications to alleviate symptoms or improve bone health.
