Does playing video games for too long affect studying capacity?

There is nothing wrong or to be worried about playing video games – even hours at a time – as long as concerns are addressed. However, your son should still have a life outside of games, he should perform well academically, socially, and physically. As far as the games themselves are concerned, monitoring to some extent is good.
Most games nowadays provide parents with tools such as chat restrictions to help protect children from language or even any interaction with strangers. Games, just as real life, can be dangerous. They can also be beneficial. They can teach your child a lot about pattern recognition, math, and other subjects. Advancing in games, you have to learn how to play – whether that means timing, coordination, reasoning skills, math. There really is no reason why your child should not play his video games so far you help him manage his time well and it doesn’t have negative effect on his academics.
