What Happened
Research shows excessive screen time in young people causes brain changes similar to Alzheimer's disease, termed "digital dementia." However, moderate internet use benefits older adults, reducing dementia risk by half. Experts recommend the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Purposeful internet use, limiting social media to 20-30 minutes daily, and offline activities are advised for brain health.
