Excessive use of social media can impair well-being and even cause disease. To help safeguard children and adolescents, an international research team coordinated by Ulm psychologist Professor Christian Montag has put together recommendations on social media use and published them in a consensus paper in the journal Addictive Behaviors. The researchers advise abstinence from smartphones throughout the entire school day. Montag also suggests using EU fines imposed on digital companies violating the EU Digital Services Act to fund further research into problematic social media use (PSMU).
