How phone notifications affect the brain and why it's dangerous

Constant smartphone notifications disrupt rest and concentration, making you check the device even for unimportant information. The unpredictability of signals forces attention switching, and unread message badges increase distraction. It is recommended to turn off alerts for secondary apps, remove badges, use focus modes, and keep the phone away from the bed. Reducing notifications restores control over your interaction with the device.

The article from 'Cursor' examines the impact of constant smartphone notifications on the brain and concentration. Author Tomer Adoni explains that sounds, vibrations, and on-screen badges regularly shift attention, prompting you to check the device even when the information is not important. The reason is the unpredictability of notifications: before checking, you don't know whether an important message, a work email, or an ad has arrived. Each signal requires a brief attention switch, and with dozens of repetitions a day, a person is constantly in a state of anticipation. Badges showing the number of unread messages also provoke opening apps. To reduce distractions, it is recommended to keep instant notifications only for important apps, turn off alerts from stores, games, and social networks, remove badges, use focus modes during work, meals, or rest, and set aside time to review accumulated notifications. Special attention is given to sleep: a phone by the bed can become a source of distraction, so alerts should be turned off or the device removed. Also, you don't have to respond to every message immediately. Reducing notifications restores control over your interaction with the smartphone.
