Smartphones are becoming a part of our daily lives. Everyone carries a cell phone. Additionally, everyone is becoming conscious about their health, but they seem less concerned about the radio frequencies their phone emits. Their smartphone screens emit a large amount of radio waves that are believed to cause cancer, leukemia, and other disorders.
The bright light on a smartphone screen glows so brightly that we can see it during the daytime. But at night, it gets a little difficult to see it. Scientists also suggest that looking at laptop or smartphone screens may be a terrible idea.
During the night, the light in the screens is bright enough that it has been compared to a ‘little window’ that daylight can peer through. This light has a similar effect to the sight of the morning sun. This means it causes the brain to stop producing melatonin, the hormone that gives your body ‘time to sleep’ clues.
Our body generally follows a cycle that helps us stay awake and alert during the daytime and suggests essential rest during the night. But when we look at screens as we are getting ready for sleep, our brains get confused. Thus, it disturbs our melatonin. And finally, it disturbs your sleep cycle like an artificially induced sort of jet lag.
To overcome this problem, many app designers have created programs like f.lux and Apple’s Night Shift mode for iPhones. Both programs adjust the light tones emitted by screens to remove the bright blue light from the display at certain times of the day.
However, more study is still needed to determine whether the dimmer light may improve sleep. Furthermore, many of the things we do with our phones are also not conducive to sleep.
