Sleep in the digital age/ The new challenge for the modern brain

2026-01-14 21:14:00, Kuriozitete CNA

In an increasingly technology-connected world, people's sleep is being severely impacted by digital devices. Notifications, blue-light screens, and social media checking have all caused nighttime rest to become shallower, more fragmented, and less restorative.

Experts warn that the brain remains in a state of alert even after the phone is turned off, making it difficult to calm down and focus the next day. The impact is strongest in younger generations, as anxiety and emotional sensitivity increase when sleep is insufficient.

Researchers highlight the importance of screen-free rest and true darkness for mental recovery. Digital sleep, more attuned to screens than to natural light rhythms, has made the bed more associated with information than relaxation.

At a time when the rhythms of life are changing, the challenge of maintaining quality sleep has become a global and modern problem, requiring awareness and concrete measures to protect mental health and daily decision-making.
