Here comes another warning for those who love to spend hours on digital screens. According to a new study, spending as little as one hour per day on tablets or smartphones could significantly increase the risk of myopia or nearsightedness.<\/p>\n
In the systematic review and dose-response meta-analysis, a daily 1-hour increment in digital screen time was associated with 21 per cent higher odds of myopia (nearsightedness), according to the study published in JAMA Network Open.<\/p>\n
The dose-response pattern exhibited a sigmoidal shape, indicating a potential safety threshold of less than 1 hour per day of exposure, with an increase in odds up to 4 hours.<\/p>\n
“These findings can offer guidance to clinicians and researchers regarding myopia risk,” said researchers.<\/p>\n
There has been a surge in nearsightedness cases largely driven by an increased use of digital screens.<\/p>\n
The team reviewed data from 45 investigations that looked at the association between screen time and nearsightedness in more than 335,000 participants from toddlers to young adults.<\/p>\n
The researchers said the risk increased significantly from 1-4 hours of screen time and then went up more gradually.<\/p>\n
However, no association was found with exposure under 1 hour, suggesting a potential safety threshold. The authors say these findings can offer guidance to clinicians addressing the “myopia pandemic.”<\/p>\n
Recently, industry experts in India discussed the role of technology and gadgets, which are some of the biggest dilemmas faced by students, parents and teachers alike, especially during exams.<\/p>\n
Long periods of screen time can affect the brain’s cognitive functions. This is basically because of the decreased attention span and prolonged screen time, which often involves sitting in a difficult posture on the bed or couch.<\/p>\n
This can cause various health-related problems, such as obesity, body aches, spine problems, and backaches too.<\/p>\n
