I like to play games, but lately I've been avoiding certain types because I think they are not good for my health. At least, they don't make me feel well afterward. For me, this is a particular type of game that requires a very high level of skill, concentration, and dexterity.
I noticed this years ago when I would play online multiplayer. After the game, I would feel extremely aggressive and I could tell that my blood pressure must have been much higher than normal.

More recently, I notice this on very difficult games such as Elden Ring, specifically the boss fights. After playing for a while I have the same feeling that I would have if I had just walked away from a near fatal accident or something. Then sometimes that evening I would have trouble sleeping.

I'm sure my physiology is different than other people. I seem to retain adrenaline/cortisol levels longer than most others. And I know that some people find the adrenaline high to be one of the main points of gaming. Still, I wonder if in general it isn't good for people to stress themselves like this when they aren't burning it off with physical activity.

I read about this online a little bit. There seem to have been some studies about it that were mostly inconclusive. Most of the findings are more interested in games being a substitute for more physical activity, so gamers may be more sedentary or overweight than normal.
