We can't say it's a bad idea to fall asleep with a screen in front of you. In fact, many people are helped to relax before bed, either by certain shows or by a background noise with which they have become accustomed to going to bed.
However, we cannot deny that a large part of the population has been complaining of sleep problems lately – and scientists have pointed out that looking at a screen is visibly correlated with insomnia and a decrease in the quality of overnight rest. .
We have compiled here five arguments that we hope will help you eliminate the TV, as a factor that interferes with a good night's sleep:
The influence of blue light
The human brain secretes melatonin to induce sleep. This hormone is emitted based on the influence of natural light on the body, and thus the human body also regulates its circadian rhythm, based on the alternation day / night. Thus, theoretically, we should fall asleep after sunset and wake up at dawn.
Based on experiments, it has been shown that artificial light can influence the secretion of melatonin, in fact rather, it can inhibit it, which drives away sleep. Okay, so far you realize that for a better sleep, the surrounding light level should be minimized.
Things get worse when we talk about blue light, specific to telephone, television and monitor screens: experts have found that it is twice as effective at inhibiting melatonin production in the human brain compared to green light.
What this means? It means that even a small screen might upset your sleep quality, compared to a filament bulb that emits yellow light, for example. Less melatonin means worse sleep, which comes harder, so for this reason experts advise people to refrain from looking at a screen about 2 hours before going to bed.
