Looking at a screen in the evening disturbs the night's rest, causing sleep deprivation.

A display disrupt the night’s rest, causing a lack of sleep. Often we watch a long time on LCD and LED screen, which can be a TV, laptop, ipad or a telephone. To see what is on the screen, light has to come out, for this a backlight LED lamp is used. The problem is that too much blue light comes out. That is very different from the natural light. So if you look at that screen for hours, the body, but especially the hormones, gets out of balance.


It is about the hormone melatonin! Melatonin is made in the evening when the sun goes down. There is naturally more red light in the natural color spectrum and that is good, but from a screen comes a lot of blue light and that stops the production of melatonin. This gives you no sleep signal and when you go to sleep, it will be more difficult to fall asleep, so your sleep is shorter and less deep. The result is that you do not wake-up rested and you are less concentrated and vital during the day. If this goes on, you will have chronic sleep shortage.

Press release from the Health Council: LED light is being used more and more: in lighting and in displays of, among other things, smartphones and tablets. In addition to the many advantages, the bluish light may also have health risks, such as disruption of the biological clock and eye damage. Advising consumers of options to limit these risks is important according to the Health Council. The Council also advocates the development of products that emit LED light with less blue and more research into the health effects of LED light. Exposure to LED light is increasing More and more LED lamps and screens are being sold, and with each generation they become luminous. Moreover, people spend more and more time in front of a screen: at home, on the road, at work. Thanks in part to flexible working hours and more screen use when spending their free time, they also do this more often in the dark evening hours than before. Led light contains a relatively large amount of blue. Blue light makes people more alert, which can be favorable or unfavorable depending on the time of day. Disruption of the biological clock Light in the dark hours can disrupt the biological clock of people and thus have adverse effects on their health and well-being. There are scientific indications that led light does this stronger than other light. The biological clock provides a cyclical course of heart rate, hormone secretion, body temperature and cycle of sleep and waking. Disruption of the biological clock can lead to shorter sleep, reduced attention and a higher risk of accidents. More.....
