TVs and Smartphones Are Emitting Blue Radiation Which Is Speeding Up Ageing in Humans, Study Finds

Health

Smart TVs and Smartphones are trending these days. People keep looking at the screens even when they are in bed. Many times they sleep keeping the devices on. But watching these screens may be harmful. It is because, radiations from a computer, phone, and other household appliances may lead to prolonged exposure to blue light. Researchers from Oregon State University have conducted research which reveals surprising outcomes of exposure to blue light. According to the latest research, the blue radiations produced by the light-emitting diodes damages living cells in the retina as well as the brain. The research, published in Aging and Mechanisms of Disease, relies on the trial over a household fruit fly. The team has selected the creature because it has cellular and developmental mechanisms the same as animals and humans.

Jaga Giebultowicz, a researcher in the OSU College of Science who studies biological clocks, led the clinical trial. The study reveals the impact of 12-hour blue light exposures on flies. Scientists have used a blue LED light that simulates blue radiation in devices like smartphones and tablets. First of all, they have started with exposing flies to a 12-hour cycle of blue radiation from LEDs. After that, the team has compared those flies with the flies kept in light without blue wavelengths and flies kept in total darkness. As a result of the experiment, they have found that exposure of fruit flies to blue light for 12 hours has shortened their lives. The same flies had damage in the cells of retina and brain cells, i.e., neurons. Even more, the flies had lost their ability to move upward and climb the walls of the cage.

Apart from this, researchers have included a group of fruit flies without eyes aiming to know whether it helps. But the results remained the same. Notably, the team of scientists has discovered the presence of brain and locomotion problems in flies that didn’t had developed eyes. It pinpoints that the light could raise health issues even if it is not visibly seen by eyes. In the end, the researchers suggest to stay away from blue radiations and avoid exposure as much as possible.
