Can Too Much Screen Time Ruin My Child's Posture?

The term "text neck" (also called "smartphone neck") is becoming widely recognized. When you tilt your head forward to look at a screen, the cervical spine bears enormous strain. According to the Japan Orthopaedic Association, tilting the head just 15 degrees more than doubles the load on the neck compared to a neutral position.

Effects on children: Children's skeletal systems are still developing, making them more vulnerable than adults. If a forward-bent posture becomes habitual over long periods, it can contribute to rounded back, rolled shoulders, and headaches.

Good posture tips: ① Hold your phone at eye level or slightly below — don't crane your neck down. ② Position the computer screen at eye level or slightly below. ③ Sit deep in the chair and use the backrest. ④ Avoid lying on the floor while using devices. ⑤ Stand up and stretch at least once per hour.

If you notice poor posture, the first step isn't to ban device use — it's to set up the right environment. Use a stand to raise the phone to eye level, match the chair and desk heights, and add a lumbar cushion. Making it easier to maintain good posture is what matters most.
