Parents arrive in my consulting room asking the same question in different words: is the phone hurting my child? The honest answer is — usually yes, but not in the way most articles claim, and not in a way that's beyond fixing.

Heavy social media use in adolescence correlates with higher anxiety, lower sleep quality, more body-image distress and a measurable drop in sustained attention. The relationship is dose-dependent — the more hours, the steeper the cost — and it is sharper for girls than boys. The mechanism isn't mysterious: variable-reward feeds train the dopamine system the way slot machines do.

1) Phones in the bed at night — destroys sleep architecture and floods the nervous system right before rest. 2) Comparison feeds (Instagram, Snap) consumed during low mood — amplifies depressive cognition. 3) Constant notifications during study — fragments attention to the point that deep work becomes neurologically harder.

Don't ban — co-design. Phone out of the bedroom after 10 pm, charged in the kitchen. One tech-free meal a day. Notifications off for everything except people. A weekly 90-minute analog activity the family does together. And — quietly the most important — adults model the same rules. Teenagers copy what they see, not what they're told.

If your teen is showing signs of depression or anxiety, the screeners here are appropriate from age 13 with parental support, and a consultation is welcome.
