American content creator Andrew Feinstein conducted an unusual experiment: he placed his smartphone in a safe for 30 days. The results of brain scans after a month of digital detox were stunning.
Before the experiment, Feinstein had poor concentration, and scans showed an imbalance of neural activity in areas of the brain responsible for social anxiety, sleep, and depressive states. Areas with excessively high or low activity indicated that excessive smartphone use could be worsening mental health.
Although not having a phone created some difficulties—for example, during illness or travel—the blogger’s condition improved significantly. The doctor described the progress as “the best he had ever seen.” Particularly noticeable changes were observed in the areas of sustained attention and impulse control.
Previously, Woman&Home editor Ella Dove conducted a similar experiment, giving up her smartphone for three days. On the second day, she began to spend more time with her husband, felt a decrease in stress levels and improved sleep. The woman concluded that a digital detox helps her learn to appreciate the moment, be calmer and maintain contact with loved ones.
The results of these experiments confirm that even a short-term smartphone break can have a positive effect on mental health, concentration, and overall emotional state.
