Posture correction involves adjusting the position of the body to improve alignment and reduce strain. Good posture helps maintain the natural curves of the spine, which can prevent discomfort and injuries. Techniques for posture correction may include exercises, ergonomic adjustments, and awareness of body mechanics during daily activities. Common causes of poor posture include prolonged sitting, improper workstation setup, and lack of physical activity. Tools like ergonomic chairs, standing desks, and posture braces can assist in promoting better alignment. Regular practice of posture correction can lead to improved overall health and well-being.
