The night mode was highly demanded by users to Apple to end including on the iPhone and Mac and eventually ended up arriving with iOS 13 and macOS Mojave. But before from Apple they also included a ‘Night Shift’ mode that adapts the color to the light conditions of the room to reduce the blue light that comes from the screens of the equipment.
The blue light of the iPhone or Mac would not be as bad as we think
We all have very internalized that consulting the phone before sleeping or going to bed immediately after having been several hours in front of the television or the computer was not the most suitable to sleep peacefully. This is why the Night Shift mode or the night mode could help us sleep better, but a recent study has denied these ideas that we had ingrained.
According to the research they have done at the University of Manchester collected by The Guardian , the Night Shift of our phones could be causing an opposite effect to what we believe. This means that by applying this we could be making our dreams worse. What we had so far thought was that reducing blue light exposure before sleep prepared the body to fall asleep, but apparently this would alter our biological clock.
The study was conducted in mice although according to Dr. Tim Brown these data can be extrapolated to the human since the similarities between a mouse and a human are many. The result showed that the blue light relaxes much more than the yellow light.
Going into details, the study used lighting specifically designed to allow researchers to adjust the color without altering the brightness. In the end it was observed that the blue color less altered the organism’s biological clock. The study explains it as follows:
This makes basic sense: daylight is yellow, twilight is blue, and sunrise and sunset are quite reliable ways to tell your biological clock what time it is. Of course, at this point, we only know that it works in mice, and mice don’t have phones. But Dr. Brown comments, “We believe there are good reasons to believe that it is also true in humans.”
No doubt this is a study that will be strongly criticized by both parties but what it raises and the evidence attached in the study are quite interesting . Undoubtedly, further studies will be necessary to be able to discern whether this hypothesis is finally confirmed. It is clear that the light of mobiles, computers, or televisions does not do us any good in our biological clock but now it is time to find out the effect in a larger sample and also in humans themselves. We recommend you read the full study to see all the tests performed.
