Excessive Screen Time Endangers Your Child's Health.

In 2025, M. Khanani and a team reviewed studies on how excessive screen time affects kids and teens. They found that spending too long on devices like phones, tablets, or TVs—especially since the COVID-19 pandemic—hurts physical, mental, and developmental health.

Over 2-4 hours daily on screens raises obesity risk by 20-30%, worsens sleep, strains eyes, and causes back or neck pain. Mentally, it’s linked to 25-40% higher rates of depression and anxiety, plus increased self-harm and suicidal thoughts. Kids also face 10-20% lower grades, delayed speech, and weaker social skills from too much screen time.

Set screen time limits (under 2 hours daily for young kids) and make family media plans to protect health.
