If you want to Protect your Sleep, Your Phones Require ‘bed mode’

A researcher in London made a very sound suggestion for the phone makers to introduce the "bedtime mode" in their phones. As it is time for the user to sleep, the phone should automatically reduce the intensity of the light so that it is easier for them to sleep. This suggestion was put forth by Professor Paul Gringras of Evelina Children Hospital in London who said that the smart phones should act more responsibly when it comes to making the future models, reports BBC News. He also argues that the phone's settings should automatically filter the blue light which adjusts the body clock and robs people of their sleep, keeping them awake for long. The doctor said that every new model being introduced in the market has a brighter and bluer light.

According to Dr. Gringras, as the evening approaches and it gets darker, the body automatically begins producing the sleep hormone called melatonin. However, certain light wavelengths, especially that fall on the blue-green end of the spectrum can affect that sleep system. The study that was published in Frontiers in Public Health analyzed the effects of light emitted by the devices and professor Gringras was a part of that study, as reported by Fortune. The study concluded that the new devices these days have even brighter, bluer lights that emit more light and can interrupt with the sleep patterns. The professor said, "That is great for use in the day, but awful for use at night." He also added, "There is converging data to say if you are in front of one of these devices at night-time it could prevent you falling asleep by an extra hour."

According to Phone Arena, there are already apps out there that have been designed to reduce the impact of blue-green lights on the user's sleep, says professor Gringras.
