Video games re-wires the brain because it was not made for this kind of activity and in many instances can cause you great distress.

From my personal experiences from playing high action intense games will put your body in fight or flight response or great distress for some people. Blurred vision, tense muscles, continued headaches and etc. are signs too from flight response too.

If you play games like mind games, Family Feud, puzzles, board and card games or casino games, they require any excitable reactions. You can play them for hours with little or any side effects. For as high action games, the brain regulates your breathing and when the two are out of balance, the body goes into total chaos. Why you think you have nausea after you played certain games?

And that doesn't end there. Why you feel fatigued after you play certain games? The brain can't keep up with the hyper speed patterns of some games while it's trying to regulate your breathing as well. It can't keep up with 2 jobs (brain). The best thing to do is try to balance your breathing and brain in practice mode because high action games overstimulates your brain like your in a flight or fight response.

It's not always about frame rate and lighting. Your out of regulating breathing is cause you nausea along with your brain. Play smart and safe.

As for me, I've retired from high action intense games.
