Emotional stress is one of the biggest thing that could actually affect anyone when gamble because you would need every part of your brain to be functional and active when playing and that's why even a simple glitch in the focus of mind can lead to so many errors while gambling and even mistakes so it's better to gamble when refresh and relaxed because you would be thinking straight and not doing crazy things just to get at the winning that might be getting so hard to come.
If you are stressed, you will not be able to think clearly since you will not pay attention to it; I am not sure how it will function if your brain is already pressured. Except if you started arranging the games before you became too weary, it is not a do-or-die situation; if you are unable to place your wager, you can play when you are more free and comfortable. Betting is not something that will. Close it so you can gamble anytime. Anytime you are not in a steady mental state, you will make mistakes. As previously stated, once you're relaxed and reclining on the couch, you can choose your game. Because you will do things for reasons you do not understand. You only need your mind when gambling.
