All of our smartphones have a bright blue light with which we can see what’s on our phone’s screen even on a bright, sunny day. This light is continually emitted, even by the television, laptops, and other devices. So, where is the problem? It starts when our body and brain confuse that light for a daytime.
When we look at the phone during the night, our brain confuses it for a day and it stops releasing melatonin. Melatonin is very important because it induces sleep, and lack of it leads to insomnia. One of the best things you can do is to turn off all the devices at least two hours before you go to bed.
The pineal gland is in charge of melatonin release and it is sensitive to the blue light. Some of the experimental researchers have found that smartphones are bad for people who use them before they go to sleep. This impact is much bigger when it comes to a teenager because they are more sensitive to the effects of light than adults. So, video game or television show before bedtime is a thing that can delay sleepiness for an hour or two.
Blue Light is Just One of the Concerns
Dr. Martin Blank from the Department of Physiology and Cellular Biophysics at Colombia University and a group of scientist are making an international appeal to the United Nation where they are showing danger linked to the electromagnetic emitting devices, such as Wi-Fi and smartphones.
There are some concerns regarding cancer and its connection with those devices. The fact that a child’s brain intakes four times as much radiation than an adult brain shows us how our kids live in a modern time with a bunch of smartphones and other devices around them.
The Possible Solution
You need to turn off all the lights before bed time. This means no TV, no laptops and most certainly no smartphones. You can read a book instead.
If you just cannot live without your smartphone, you can download an app that can adjust a color of your computer’s display according to the time of day. It will be warm at night and bright during the day. Improve the quality of your sleep and avoid bringing phones and computers to your bedroom.
