The impact of digital technologies on the human hormonal system is due to constant interaction with the digital environment. The blue light of screens and even the psychological stress that comes with overuse of technology can affect the secretion of hormones such as cortisol (a stress hormone) or melatonin (a sleep hormone). From a psychological point of view, it can lead to sleep disorders, anxiety or difficulties in coping with daily stresses. To maintain physical and mental health, it is necessary to use technology with caution.
