A study has found that watching video for more than an hour a day has a negative effect on a child’s growth and development.

Hamamatsu Medical University’s Child Psychological Development Research Center in Japan conducted a survey of △18 months after birth △24 months △32 months △ 4-year-old children to find out how the act of watching video for a long time on a smartphone or TV affects child growth The study was carried out on 885 people.

1 hour or more video viewing time is one of the three abilities of a child’s growth and development ▲ communication ability (response, expression, writing ability) ▲ daily life ability (the ability to adapt to personal, family and community life) ▲ socialization ( interpersonal relationship, the ability to cope with situations) ) and how it was related. Video content included videos viewed on television, computers, and mobile phones, as well as video games.

As a result of the study, children who watched videos for more than 1 hour a day showed low communication and everyday life skills. The longer the video was viewed, the more the optic nerve center responsible for vision was stimulated, while the frontal lobe, which regulates cognitive and big thinking abilities, was not activated.

However, it was confirmed that children who play outdoors for more than 30 minutes 5 to 6 days a week gradually reduce the rate of decline in daily life skills due to video viewing and better socialization scores. The research team said, “If you play outside often, you can reduce the growth decline caused by the time you watch videos by 18%.”

The research team added, “However, communication skills did not improve even when they were outdoors for more than 30 minutes a day.

The results of this study were presented in the American pediatric journal ‘JAMA Pediatrics’.
