Q: Before you get mislead by the question, this is more an inquiry about a personal experience of mine, and not a generalized question on of gaming on health. I am a calm gamer for the most part. I don't throw temper tantrums if I lose, I don't break controllers, nothing like that. I am not a sore loser and I don't have any kind of rage like that. However, it seems like whenever I am playing a competitive player-vs-player game I begin to become hot, a little sweaty, dry mouthed, and even a bit of weakness (shuttering knees when going down the stairs afterwards). I can drink a ton of water afterwards as I feel dehydrated. Remember I am fine when playing a game against an AI, so it's not a condition related to video games either. Overall it's kind of like the same feeling you get after you just jogged for a short period of time. I am curious on what exactly this sensation is/caused by when playing games online?
A: Sounds to me like the feeling you're getting is from the effects of adrenaline. This is a hormone that is released when your body is experiencing stressful or exciting situations. Often as the effects wear off- such as when the game is over, you can feel weak or shaky. The dehydrated feeling may simply be due to excessive sweating.
