The grip for the smartphone before going to bed has become a habit for many people. But how does that affect our sleep? New studies show amazing things.
Night mode function on the smartphone
The blue light of screens is discredited to keep awake and the
To make sleep uncomfortable. It could be so easy to avoid it: the harmful shades of blue disappear at the push of a button and the cell phone display is dipped in warmer colors.
But according to a study by Brigham Youth University (BYU), it is unfortunately not that simple. A total of three different types were tested to fall asleep at 168 people between the ages of 18 and 24. While a group should fall asleep on subjects with activated night-shift mode, another group used cell phones with deactivated night mode.
Another third group, on the other hand, should do without the cell phone entirely an hour before going to bed. The division of the participants into the corresponding groups took place according to the random principle. It was tested with iPhone screens in a total of seven nights in a row.
No differences in improving sleep
The result was sobering. There were no significant differences between the three groups. “In our entire study sample, there were no differences in the sleeping results that were due to Night Shift.
“Although there is a lot of indications that the blue light of mobile phones increases vigilance and makes it difficult to fall asleep, it is important to think about the proportion of this stimulation in light emission and which is due to other cognitive and psychological stimulations,” said Chad D. Jensen, co -author and professor at the ByU, in a subsequent press release.
