The implications of poor posture on long-term health can be quite significant. Chronic poor posture can lead to musculoskeletal issues such as back, neck, and shoulder pain. Over time, it can contribute to conditions like arthritis and herniated discs due to the strain placed on the spine and joints. Poor posture can also affect respiratory function, reducing lung capacity. Furthermore, it can lead to decreased energy levels and negatively impact mood and confidence. Addressing posture through proper ergonomics, exercises, and awareness is essential for maintaining long-term spinal and overall health.
