In the past, people have been very deceitful, and it was enough for your father-in-law to tell you that there was something to believe. Today things are different, many people are skeptical and need verified and factual information to believe things. With everything and everything, fairy tales, rumors and urban legends almost everything continues to overflow, now today we'll see others "Facts" and other "myths" about PC monitors: Which of them is real?
Screen brightness reduces sleep quality
In general, light input affects the quality and duration of sleep, and since digital screens emit artificial light, we can say that they have an effect on sleep quality. But many other things also produce that same input light, such as light bulbs, headlights, television, etc. So what is the difference?
The natural sleep / wake cycle of the human body is known as circadian rhythm, and a touch of bright green light, especially found on the blue and white visible. Warm light tones, such as yellow and orange, also have an effect on sleep quality but are certainly less blues and whites. For this reason, warm home lights are recommended, and cold lights at work – to keep us awake.
The use of light screens, especially in low-lying areas, disrupts circadian rhythm, causing the brain to believe that it is daytime, stopping the release of melatonin (a hormone that suppresses and prepares it for the night). For this reason, most screens have filters such as Low Blue Light, or apps have "Night mode" or Apple's Night Shift which is well known, to reduce this effect.
The verdict: That's true.
Monitors can cause cancer
This is a perfect example where a hold is not equal to an encounter. Several years ago enthusiastic studies have used error-prone methods and the bad science of trying to prove the connection between the use of screens and life-threatening illnesses like cancer.
To be clear, these studies have found suspicious association between people who spend too much time in front of screen and cancer cases, but these studies also ignore other factors such as that today there are more people with cancer than ever before with the simple fact that we have better ways to find it.
At the same time, people are increasingly spending more time in front of screens, but life expectancy is increasing. Simple statistics, the longer you live, the greater the chance of getting cancer, among other things. On the other hand, man is now more sedentary than we were before, eating edible food and long etcetera for example other possible causes that can also promote cancer.
The fact is, there is hardly any strong research to show that being in the presence of PC screens or prolonged monitoring causes the cause of cancer. Not one.
The verdict: false
Screens cause diabetes and depression
As in the previous example, this is just another attempt to try to find one cause of the problems caused by the change in people's lifestyle that has been passing for years, and there is no critical scientific study that links one thing to another.
People who spend a lot of time in front of PC monitors have higher incidence of illnesses such as diabetes, obesity and stress, and also screens are not the cause, but a combination of their sedentary lifestyle. The more time you spend sitting and exercising, the more likely you are to gain weight and have health problems, and people with health problems are more likely to have depression or diabetes. This is true.
The verdict: false
PC monitors hurt the eye
Most eye surgeons agree that spending too much time looking at the screen is "not good" to the eyes, but depending on who asks you it will get different answers as to how much damage it causes, or how much damage it causes.
The biggest fear they have is that screens cause macular degeneration, which is one of the main causes of blindness. However, there is no convincing evidence that this long-term damage is real and, nevertheless, many PC monitors have technology that does not harm individual viewing life.
The verdict: true….
Sitting too close to the screen damages your sight
Many think that this is a myth simply because of the increasing evidence of the undeniable evidence, bad science and myths of older women, but it turns out that in this case there are references: in 1967 it was found that colored televisions emitted between 10 and 100,0900 times the amount of radiation
But this problem is no longer available, since the television, screens and reality PCs are no longer emitting radiation, which was in CRT monitoring, so that is not a problem now. Of course, if you look closely at the screen you will have to force your eyes and that, in the end, it will eventually cause less head, shoulders and neck.
In other words, it doesn't matter if you live far from or near the monitor as long as the distance is right so you can see clearly and without stressing your eye or neck, whether it is lower or lower.
The verdict: false
Darkness causes vision problems
We have all been given "advice" that using a PC in a bright room is not good for the eyes, but this has no scientific basis to prove that. It started as always, with the myth of the old women, and this is where it should last, but unfortunately this baseless myth continues to circulate on the Internet.
However, in fairness, if you look at a bright screen in a dark room it will affect the eyestrain of your eyes, but it has no effect on the vision. In fact, doing this makes us less involved, then drying our eyes, and thirst causes irritation and pain. But what is the opinion, there is no indication that it is totally corrupt.
The verdict: false
