Mindfulness programs for children and adolescents have been implemented in thousands of schools worldwide, with research showing benefits including improved attention, reduced anxiety, better emotional regulation, and improved academic performance. The MindUP program, developed by the Hawn Foundation, and the .b (dot-be) curriculum for teenagers are among the most widely studied school-based programs. Research at the University of British Columbia found that elementary students who received mindfulness training showed measurable improvements in math scores and significant reductions in aggression and peer-reported stress. Teaching mindfulness young is increasingly seen as a critical preventive mental health intervention.
