Early Smartphone Use Linked to Obesity, Depression in Children
A new study found that children who get smartphones before age 12 are more likely to become obese, depressed, and have trouble sleeping.
A 10-year-old boy in Mumbai gained 10 kg in just five months after getting a smartphone, became very quiet, and started eating a lot of junk food.
Experts say that young children's brains are still developing and can't handle the information and addiction risks that come with smartphones.
They suggest that parents should limit screen time and encourage activities like playing outside, reading, and spending time with family instead.
Parents can also set rules like no phones at the dinner table or in the bedroom to help their children stay healthy.
