The night mode has been highly requested by Mac and iPhone users to Apple. The Cupertino firm ending up including this feature on both iPhone and Mac with the launch of iOS 13 and MacOS Mojave. But earlier from Apple also included a ‘Night Shift’ mode that adapts the color to the lighting conditions of the room to reduce the blue light from the screens of the equipment.
The blue light on the iPhone or Mac is not as bad as we thought
We should all be aware by now that using our smartphones before going to sleep or going to bed immediately after having spent several hours in front of the television or the computer was not the best way to sleep peacefully. That 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 deep-rooted.
According to the research they have done at the University of Manchester collected by The Guardian, the Night Shift of our mobiles could be causing an effect contrary to what we believe. It means that by applying this, we could be worsening our dreams. What we had all thought until now is that reducing exposure to blue light before going to bed prepared the body to fall asleep, but apparently, this would alter our biological clock.
Results of the study
The study was carried out on mice, although according to Dr. Tim Brown, these data can be extrapolated to the human because the similarities between a mouse and a human are many. The result showed that blue light relaxes much more than yellow light.
The study used lighting specifically designed to allow researchers to adjust color without altering the brightness. In the end, it was observed that the blue color altered the biological clock of the organism less. The study explains it in the following way:
It makes fundamental sense: daylight is yellow, twilight is blue, and sunrise and sunset are fairly reliable ways of telling your biological clock what time it is. It works on mice, and mice don’t have phones. But Dr. Brown comments, “We think there’s a good reason to believe it’s right in humans as well.
No doubt, this is a study that will be sharply criticized by both parties, but what it raises and the evidence attached in the study are quite impressive. No doubt, more studies will be needed to discern whether this hypothesis is confirmed in the end. It is clear that the light from mobiles, computers or televisions does not do us any good in our biological clock but now it is time to find out the effect on a larger sample and also on humans themselves.
