Kids spend ~70 minutes of the school day on their phones. But caregivers can help by modeling healthy screen time, Dr. @jasonmnagata.bsky.social says. Caregiver phone use is “one of the biggest predictors of adolescent phone use, or screen use in general,” he explains. https://ucsfh.org/49b2mGg

Call it muscle dysmorphia or bigorexia, but body image issues aren’t always just about getting smaller. Experts explain why wanting to be bulkier can be a problem.
