Since Pong first became a massive hit in the early ‘70s, parents have warned their kids that playing video games will rot their brains. How it not? Most gaming involves kids sitting alone in their homes, mashing buttons and a single game could go on for hours. There’s a good reason why parents should be concerned about the amount of time their kids spend staring at screens, but does gaming have an upside?A 2022 report from the Karolinska Institute in Sweden has found that playing video games actually increases a child’s IQ. "Our results support the claim that screen time generally doesn't impair children's cognitive abilities, and that playing video games can actually help boost intelligence," neuroscientist Torkel Klingberg from the Karolinska Institute in Sweden said in 2022.To reach this conclusion, the researchers looked at nearly 10,000 kids between the ages of 9 and 10 who, on average, spent 2.5 hours a day watching TV or online videos, 1 hour playing video games and 30 minutes socializing online with friends or family. Two years later, they compared data on 5,000 of these kids and found that those who spent more time than the norm playing video games had an IQ increase 2.5 points above the average rise.The IQ point increase was based on their performance in tasks involving self-control, flexible thinking, memory, reading comprehension and visual-spatial processing. “We didn’t examine the effects of screen behaviour on physical activity, sleep, well-being, or school performance, so we can’t say anything about that,” says Torkel Klingberg, professor of cognitive neuroscience at the Department of Neuroscience, Karolinska Institutet. The researchers also note that there was no increase in IQ points for those who watched more TV or spent more time on social media than the norm. Are video games bad for kids?Kids who run to share this story with their parents should be careful because IQ is just one factor affected by playing video games. "We didn't examine the effects of screen behavior on physical activity, sleep, well-being, or school performance, so we can't say anything about that," said Klingberg. "We'll now be studying the effects of other environmental factors and how the cognitive effects relate to childhood brain development."The study is a shot in the arm for those who believe video games are good for kids and those who like to play them. However, we know that video games can cause serious problems if played excessively. Studies show that gaming is associated with obesity because when you sit in front of a screen all day, you don’t have much time for exercise. Excessive gaming has also been associated with depression, anxiety, aggression, sleep deprivation, insomnia and circadian rhythm disorders. Video game addiction has also become a serious problem and may affect over 60 million people worldwide. Parents should be wary of signs of video game addiction in their children, which include a loss of interest in other hobbies, withdrawal symptoms when they're not gaming, and aggression. As with anything, the key to getting maximum benefits from gaming is to make the activity part of a balanced lifestyle that includes plenty of physical activity, socializing with friends, lots of sleep, good nutrition and a fair amount of reading time. The Child Mind Institute says kids over 6 should spend at most 1 hour a day playing video games on school days and 2 on the weekends. Kids under 6 shouldn't exceed 30 minutes a day playing video games.
