No, e-sports are much more intense. Pros play every single day for 8-16 hours. Idk about chess, but in competitive games, they don't fake anything. Everybody wants to win and to win they have to train that much. Before, their habits were very unhealthy. They don't eat healthy and they barely sleep. They obviously never exercised. But now they're getting some maintenance. They're required to exercise but afaik the meals and sleep schedule are still their own to maintain, which is obviously still very unhealthy.

As well, carpal tunnel and other hand and arm problems are very common. And these are reported conditions. Some most likely have hemorrhoids from sitting that long on the chair every single day(and eating unhealthy).
