Are you getting little sleep? Blue light (from smartphones and PCs) makes you sleep badly


There are currently many studies investigating the use of smartphones by users. These studies look at how these devices affect users, who sleep less due to the blue light emitted from the smartphone screen.

How to protect yourself from the blue light emitted by cell phones?

New technologies, in addition to improving communications, can also have negative 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 from the smartphone screen.

Is it dangerous to sleep with the phone?

Each natural light radiation corresponds to a wavelength that determines its color. Blue light is between 478 and 483 nm. Although this is still weak, it disturbs the biological clock of man. It can also destroy the retina and cause cataracts.

It causes progressive degeneration of the macula, which allows you to see the details. In severe cases, exposure to blue light can cause vision loss.

The brain understands that it is still daytime when the mobile is used at night

due to the light emitted by the devices.

From the same company, they claim that this slows down the secretion of melatonin, the sleep hormone, and creates difficulties when it comes to bedtime. But that’s not the only negative effect, since you can also suffer from nocturnal awakenings, poor quality rest, insomnia episodes, and other effects such as visual stress, headaches, irritation, and eyestrain.

So you can avoid technological insomnia

When a user uses a mobile phone before going to sleep, it activates his brain, as it forces him to pay attention, thus not allowing 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, as their light is detrimental to rest, including the LED lights they emit. 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, activating the night mode on smartphones is also 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.
