Digital aging: Too much blue light from screens makes you grow old faster

Too much blue light from gadgets like televisions, laptops, and smartphones can accelerate the aging process, a new study warns. Researchers found that the light could also lead to the onset of obesity and psychological problems.

“Excessive exposure to blue light from everyday devices, such as TVs, laptops, and phones, may have detrimental effects on a wide range of cells in our body, from skin and fat cells, to sensory neurons,” says Dr. Jadwiga Giebultowicz, a professor at the Department of Integrative Biology at Oregon State University, in a media release. “We are the first to show that the levels of specific metabolites – chemicals that are essential for cells to function correctly – are altered in fruit flies exposed to blue light.”

The research team experimented with fruit flies and discovered that the light from screens affected them as well. This is significant, since humans and flies have similarities on a cellular level.
