About the Night Sleep

    I have had some trouble about sleeping at night recently and read the news, "Phones need 'bed mode' to protect sleep" by James Gallagher on BBC news, saying that smartphones, tablets and e-readers can distrupt our sleep. I found the article really useful because of two main reasons. First, the claims rely on the ideas of an expert called Prof Paul Gringras who is from Evelina Children's Hospital in London. Second, explaining the bad news, he also have a solution for it. The professor says that these devices has a blue light which delays the body clock and keeps poeple awake later into the evening and as the new model getting developed, devices started to be more "bluer and brighter" . If the manufacturers show more responsibility and add a sleep aware software that "could automatically filter out the blue light" as it gets darker in the evening,  we can protect ourselves and our sleep from the affects of these smart devices. In conclusion, Prof Gringras shows people how to solve their sleep problems but until the producers make an effort for this, we should turn them off to have a better sleep at night.
