Currently, there are many studies that investigate the use of smartphones by users. These studies analyze how these devices affect users, who sleep less because of the blue light emitted by the smartphone screen.
New technologies, in addition to improving communications, can also have adverse health effects if people overuse these devices. This is what Bruno Madeira, co-founder of Koala Rest, says in the statements made by the Europa Press agency.
People who use mobile phones sleepless and the reason lies in the light emitted by the smartphone screen.
Each natural light radiation corresponds to a wavelength that determines its color. The blue light is between 478 and 483 nm. Although this is still weak, it disturbs man’s biological clock. It can also destroy the retina and cause cataracts.
Causes progressive degeneration of the macula, which allows you to see the details. In severe cases, exposure to blue light can cause vision loss.
Are you sleeping little? Blue light (that of smartphones and PCs) makes you sleep badly.
The brain understands that it is still daylight when the cell phone is used at night due to the light emitted by the devices.
From the same company, they say that this slows down the secretion of melatonin, the sleep hormone, and creates difficulties when it is time to go to sleep. But it is not the only negative effect since you can also suffer from nocturnal awakenings, a rest of poor quality, episodes of insomnia and other effects like visual stress, headache, irritation, and eyestrain.
So you can avoid technological insomnia
When a user uses a cell phone before going to sleep, he activates his brain, as it forces him to pay attention, so doing not allow the person to relax and rest. This “technological insomnia” can be avoided by following a series of guidelines, as reported by Koala Rest.
First, avoid having electronic devices in the room, such as smartphones or televisions, since their light is harmful to rest, including emitting LED lights. Another action to take would be to stop using smartphones and electronic devices two hours before going to bed, so the brain can produce the hormone responsible for regulating sleep.
Finally, even the activation of night mode on smartphones is of great help, since the light sent by smartphones is limited in this mode and its emissions are reduced. Some tips that will allow you to sleep more and rest better at night.
