Health experts in the UK are examining a potential link between heavy smartphone and tablet use and a rise in carpal tunnel syndrome (CTS), a painful condition affecting an estimated 340,000 people nationwide.

CTS occurs when tissue inside the wrist swells and compresses a major nerve, leading to symptoms such as pain, numbness, tingling, weakness, and difficulty gripping objects.Reports suggest cases may have increased by around 25 per cent over recent decades, prompting concern among medical specialists.

According to Professor Adam Taylor, an anatomy expert, the way people hold mobile phones may place unnatural strain on wrist tendons, potentially increasing risk, particularly when usage exceeds four hours a day.

Some studies have indicated that frequent texting may quadruple the likelihood of developing CTS, while using a phone with both hands may increase risk even further.However, experts stress that mobile devices are not the only contributing factor.Obesity, diabetes, previous wrist injuries, and occupational strain are also significant risk factors.

CTS is most commonly diagnosed in adults aged 40 to 65, with women reportedly three times more likely to be affected due to anatomical and hormonal factors.

Treatment options vary depending on severity and include lifestyle adjustments, wrist splints—particularly at night—physiotherapy exercises, steroid injections, and, in more advanced cases, surgery.Specialists also advise simple changes in phone-handling posture to reduce strain.If symptoms persist, worsen, or interfere with daily life, medical assessment is recommended to prevent potential long-term nerve damage.
