Orthopaedic Surgeon Explains How Constant Phone Use Strains Hands And Wrists

Prolonged smartphone use can strain the muscles, joints, tendons, and nerves of the hands and wrists, according to orthopaedic surgeon Dr Barun Datta. While the effects of screen time on sleep and eyesight are well known, the impact on hand structure often goes unnoticed until pain becomes prominent.

The Causes Of Strain

Using a smartphone in the same position for a long time creates problems. Using one thumb for scrolling or typing and keeping the wrist bent while texting also contribute to the issue. Constant smooth and monotonous thumb movements for app navigation, typing, and scrolling can irritate the tendons responsible for moving the thumb. Furthermore, holding phones with just two fingers without changing the hold for a long time causes pain, numbness, or weakness in the fingers and hands.

Long-Term Effects

Dr Datta warns that this repetitive strain does not develop in a day or two. Minor strain over time can harm joints and muscles in the long run. The risk of injury increases if phone use goes along with other repetitive tasks like extensive computer work, gaming, and writing. People often ignore early stiffness and keep using their devices, which can turn occasional discomfort into chronic pain.

When To See A Doctor

Occasional tiredness after long phone use is usually not a cause for concern. However, persistent pain, swelling, numbness, tingling, weakness, difficulty gripping objects, or symptoms that disturb sleep or everyday activities need medical evaluation. Dr Datta also notes that not every hand or wrist problem comes from smartphone use, as conditions affecting tendons, joints, or nerves can have several causes.

Context

Repetitive strain injuries in modern life often stem from the steady growth of digital device usage in daily routines. Medical experts frequently advise modifying device habits and taking regular breaks to prevent long-term joint and muscle damage.
