Blue Light From Smartphones, Computers, TVs Harmful For Brain; Speed Up Aging

These blue light flies had damage to their retinal cells and their brain neurons, and they even experienced impaired locomotion, as they had difficulties climbing the walls of their enclosure.

The study revealed that the blue light that emanates from almost every electronic device can actually speed up the aging process for consumers, regardless of whether or not the light shines directly into their eyes.

Giebultowicz said: "It was very clear cut that although light without blue slightly shortened their lifespan, just blue light alone shortened their lifespan very dramatically".

During the study, researchers analyzed how a group of fruit flies responded to daily 12-hour exposure to blue LED light. Even relatively mild light was seen to shorten their lifespan by 5-15%, the researchers added.

However, Giebultowicz points out that this result can not be applied to humans as the human brain "would receive much less light than fly brains".

But these mutant flies which were exposed to the blue light also suffered brain damage, suggesting that the harmful effects of the waves are not exclusively the result of them beaming into your eyes.

If you don't feel like you have much in common with a fly, previous studies in humans have looked at short-term effects of blue light exposure.

And industry experts predict its share will continue to rise, topping 60 per cent by the end of next year.

It has always been suspected to be the reason that night shift workers, exposed to artificial light for longer, have a greater risk of cancer. "That means after 12 hours of blue light, they have high activity, which is telling us that the cells are under stress".

Blue light can penetrate the deeper layer of skin, making skin thinner and more fragile, dermatologists also claim.

She said: "We can only say that long-term exposure to blue light has damaging effects on cells - and cells in flies and humans function in a similar way".

However research assistant Eileen Chow, co-first author, points out that shunning artificial light would benefit human health.

The scientists say their findings raise questions as to whether spending too much time in artificial light can impact overall health. Then we started asking, what is it in the light that is harmful to them, and we looked at the spectrum of light.

For those desirous to guard their eyes from blue gentle, the researchers voice carrying glasses with amber lenses that might perchance filter blue gentle and changing cellular phone and other machine settings to dam blue emissions. The blue light used in the lab is similar to the blue light that emanates from phones, computers, and other electronics.

Blue light, which has one of the shortest wavelengths, is also emitted by flat screens, smartphones, tablets and street lights with LED bulbs, which are on the rise in Britain. A Harvard study, for example, found that when people were exposed to several hours of blue light, it suppressed the production of melatonin, a hormone that regulates sleep, and shifted their circadian rhythms.
