Does Phone Use Cause Premature Aging? New Research Reveals Risks

A modern study has linked prolonged exposure to light emitted from mobile phone screens to premature aging, including hair whitening, wrinkles and the development of under-eye bags. Researchers at Bahria University Medical & Dental College in Pakistan found individuals who spend six hours or more daily using their phones were seven times more likely to experience premature graying of their hair compared to those with less screen time.

The study, published in the Pakistan Medical Association Journal, also revealed that nearly three-quarters of heavy phone users exhibited under-eye bags and dark circles. Researchers attribute these effects to the blue light emitted by phone screens. “This highlights the importance of educating about the potential risks associated with excessive screen time,” the authors wrote.

The research involved 450 adults, with almost half admitting to using their devices for up to seven hours a day, and one in ten using them for even longer periods. Those with the highest usage rates were seven times more likely to have gray hair compared to those who used their phones for just two hours daily. Other signs of aging, such as dry skin, wrinkles, and hair loss, were also significantly more prevalent in the high-usage group.

Scientists suggest mitigating the risk by applying sunscreen before using a phone or adding an ultraviolet filter to the screen. The study did not specify the type of ultraviolet filter, or the SPF level of sunscreen recommended.

While the study establishes a correlation between screen time and visible signs of aging, it does not definitively prove causation. Further research is needed to fully understand the mechanisms by which blue light may contribute to these effects. However, the findings add to a growing body of evidence concerning the potential health impacts of prolonged digital device use.
