Question
What is "Tech Neck", and how does it affect postural health?
Answer
Tech Neck, also known as Text Neck Syndrome (TNS), is a postural dysfunction caused by prolonged use of electronic devices such as smartphones, tablets, and computers. It is characterized by forward head posture, rounded shoulders, and excessive thoracic kyphosis. These postural deviations lead to muscle imbalances, increased stress on the cervical spine, and a higher risk of developing musculoskeletal pain and dysfunction. Research shows that excessive screen time—averaging nearly five hours per day for Americans—has significantly contributed to this condition.
Over time, the sustained forward head position places additional strain on the cervical spine, increasing the load from approximately 12 pounds in a neutral position to up to 60 pounds when the head is fully flexed. This excessive load can cause ligament stress, muscle tightness, and joint dysfunction, leading to symptoms such as neck pain, headaches, and even respiratory dysfunction due to altered diaphragm mechanics. Addressing Tech Neck requires a multifaceted approach, including ergonomic adjustments, posture correction exercises, and patient education to promote better habits and reduce strain on the cervical spine.
