It is true that gambling can make you stressed, but let's not forget that there are also a lot of people who gamble precisely because they are under stress. In that respect, the term stress has 2 meanings. First form can take disastrous forms because it involves high amounts that can be gambled through. Eventually you end up in a vicious circle if you keep gambling. I think that gambling in an online casino gives a very different stress and relaxation than in a physical casino. At home you are in your own environment and you can also generate your own music and background.
