The blue light does not always harm rest, activity on devices and personal habits influence more than what was thought.
For years it was believed that the blue light of cell phones, televisions and computers It was the main responsible for sleep problems, however, recent studies show that not all exhibitions affect the quality of rest significantly, but that it is something more complex.
Traditional explanation argues that blue light Reduces melatonin productionkey hormone to induce sleep, generating greater alert and making it difficult to reconcile it. This promoted the use of filters and recommendations to avoid devices before sleeping. However, the scientific evidence that supports a direct relationship It is weaker than it was assumed.

According to recent investigations, the Intensity of the brightness, the proximity of the device and the exposure to natural light During the day they can modify how screens affect sleep. For example, watching television three meters away did not alter hormonal levels in a study, while using an iPad at maximum brightness did slightly reduced melatonin.
According to a note from The New York TimesLauren E. Hartstein, an assistant professor of psychiatry at the University of Arizona, explained that many studies were conducted with small or laboratory samples, without reflecting everyday life. Mariana Figueiro, a researcher at the ICAHN School of Medicine at Mount Sinai, added that “Although exposure to blue light can reduce melatonin levels, the use of screens does not always produce this effect.”
Digital Activities: The determining factor
Beyond the blue light, the Type of activity on devices seems crucial. Interactive activities such as video games, social networks, online purchases or bets They activate the brain reward system and make it difficult to disconnect, according to Daniel Buysse, a psychiatrist and professor at the University of Pittsburgh. Hartstein also points out that both rewarding interactions, and communicate with friends, like those that generate discomfort, such as Read disturbing newsThey stimulate the brain and complicate the sleep.

On the other hand, the Liabilities of screenslike watching television or reading, it depends on the content. For those fighting negative thoughts, relaxing programs or readings favor rest, Aric Pather, a psychologist at the University of California, San Francisco, advised.
If a person manages to fall asleep easily, rest well and feel renewed, There is no reason to modify your habits regarding the use of screens before sleeping.
