This strategy works in just a week



The study, conducted in collaboration between the Netherlands Institute of Neuroscience, the Amsterdam UMC and the Netherlands National Institute of Public Health and the Environment, investigated the use of screen times in Dutch adolescents aged 12 to 17 years divided the group of teens into two groups: frequent screen users (those who saw screens on average for four hours a day) and infrequent screen users (those who saw screens for about an hour a day). Then they looked at how these teenagers slept by talking on the phone normally at bedtime, wearing goggles at bedtime, and no longer using screens before bedtime.

After Five Weeks, the researchers found that the biggest sleep breaker is blue light, which is emitted by screens of all kinds. Blue light can affect our brain clock by turning off the production of melatonin, which makes us feel that we are not even tired. The researchers found that the use of sunscreens or the use of curbs led to participants falling asleep 20 minutes earlier. Also, the change went quickly: the young people said that after a week with glasses or screen bed before going to sleep better!

"Adolescents are spending more and more time on screen-based devices, and sleep disorders are common in this age group." Dirk Jan Stenvers, a researcher from the Department of Endocrinology and Metabolism at the UMC in Amsterdam, said in a press release. "Here we show very simply that these sleep disorders can easily be reversed by minimizing the use of the evening screen or exposure to blue light." Based on our data, sleep disorders in adolescents and delayed onset of sleep are likely to be at least partially caused by blue light . " Screens.

The researchers plan to repeat this study on adults next.
