If someone plays poker professionally, I think the ideal is to play about 8 hours a day and choose one or two days a week to rest, which could be Saturday, Sunday or a holiday, depending on the tournament days they participate in. However, if someone plays recreationally and does not have poker as their main source of income and has a job, it is advisable to play no more than 4 hours on the days they play, and not every day. It can be every other day, otherwise it can affect their performance in their professional life and in other areas of their daily social life.
