What is the danger of blue light from smartphones and computers? Source:

Scientists suggest to reconsider your daily habits and not to use smartphones before bed

While the world becomes more digital, we don't always notice how different our daily lives. Meanwhile, more and more people report difficulty falling asleep, not always realizing that the reason lies right on their bedside table. so firmly established in our lives that they become harder to separate. However, in addition to the influence of blue light on biological rhythms, it negatively affects other aspects of your health. So, the new dedicated blue light emitted by phone screens and laptops, means that the light can damage brain cells and affect life expectancy. Blue light — is the wavelength in the spectrum of light visible to the human eye and often used in artificial light. Previous have shown that prolonged exposure to blue light can cause sleep disturbances and eye damage.

Blue light promotes the aging of organisms

Recently we told you about the dangers of the day, and about the importance and necessity of healthy sleep write . However, one of the main problems, which affects circadian rhythms — circadian rhythms with a period of about 24 hours, followed by all living beings on the planet — this is a blue light that shines from the screens of smartphones, tablets and computers. Thus, the results of a study recently published in the journal indicate that blue light reduces the lifespan of fruit flies Drosophila melanogaster.

Wave blue light affect circadian rhythms

The Study included a test of how flies responded to a daily 12-hour exposure to blue light, the same wavelength emitted by phones and tablets. Flies exposed for 12 hours and 12 hours of darkness, had shorter life span compared to flies that were 12 hours at 12 and 12 hours in normal light. In addition, flies were observed not only damage to the retinal cells and neurons in the brain, but present movement disorders — they could not rise and fall on the walls of their containers. The results also showed that blue light can cause damage even if the flies don't see it. Thus, scientists have found another proof of the negative impact of blue light on living organisms.

What else you need to know about blue light

The Researchers note that today it became known that the blue light emitted from digital screens can mimic daylight and to prevent the production of the body — a hormone that AIDS in sleep. Thus blue light is useful in the daytime, as it improves mood, reaction time and concentration, however, melatonin has not been violated, the researchers recommend not to use the devices for hours before bedtime. Technology companies have recognized the problem — and Apple and Google have provided the settings for their operating systems, which reduce the blue light and dark settings modes that dim the screen and designed to be less jarring for the user's eyes in low-light conditions.

Experts advise to use computers and smartphones in the afternoon

Scientists are advised not to neglect sleep hygiene and to reduce the use of devices at night. Blue light emitted by gadgets in the dark in addition to problems with impaired vision and the risk of premature aging, a risk that many have resorted to sleeping pills. However, many drugs only mask core and are accompanied by many unpleasant side effects.
