Pilar Durán Hernández, head of the Faculty of Sciences (FC), of the National Autonomous University of Mexico (UNAM) announced that according to recent investigations it was found that the overexposure in the blue light of mobile devices produces waterfalls especially before sleeping.
In addition to that it also causes disturbances in sleep quality and circadian rhythms by photic or light stimulation. In the case of the eyes, the damage is found in the organ that modulates vision.
When participating in the International Brain Week 2023, he reiterated that all excess is bad, since the exaggerated use of cell phones and digital devices causes macular degeneration, changes in corneas and dry eye.
What does the UNAM say in relation to overexposure to mobile devices?
There are several consequences of prolonged use of mobile devices
The Neurobiology specialist explained that sleep is controlled by a homeostatic process (the ability of living beings to maintain internal stability in their bodies) and another circadian process, so it is necessary to sleep to have good health, and rest to recover what we lost during sleep; when we are faced with a photic stimulus this no longer occurs.
In the meeting organized by Universum, the UNAM Science Museum pointed out that the healthiest blue light that human beings can receive is the natural one, the one that comes from the Sun, and that allows us to have a good sleep-wake cycle, fix vitamin D and suppress melatonin upon awakening.
In adulthood, he continued, new neurons are generated, a process that could be reduced when faced with photic light stimuli at night, as well as a high stage of neuroinflammation; that is, a high degree of oxidative stress in our tissues, a decrease in learning-memory processes and alterations in our state of mind.

In the case of young people, avoiding sleep and not respecting their circadian rhythm could take its toll in the long term, since neurodegenerative diseases can be triggered or aggravated by alterations in the sleep-wake cycle.
As we have mentioned in other informative notes of The Truth Newsscientific studies have found that spending too much time in front of the cell phone is related to greater anxiety and greater isolation, especially in young people.
