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.
It's true. It affects us a lot more than we can think of. When you are getting older it's more difficult to control stress and being asleep in a short amount of time. This is why we should not be gambling if we think we are on the brink of closing our eyes and falling asleep because that's when we make mistakes and those mistakes could ruin our planned budget if suddenly we press the wrong button while we are betting half asleep.
I mean, I have been there that's why I could tell the story. I made the mistake of pressing the wrong button just because I wanted to continue betting and I was chasing my losses using my phone before I went to sleep, I was in my bed at that moment.
So for me now, the general rule is to avoid using the phone to gamble or better, go upstairs in my bedroom without my phone in my hand or beside me. That way I could avoid making the same mistake that I had made before.
