Most of the nutrients in mushrooms are behind a cell wall of chitin, which is a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi.
because of this chitin, eating a mushroom raw is not very nutritious and you miss out on most of the health benefits.
Not being nutritious and making you sick are rather different though. Although porcini can be eaten raw it is probably most commonly fried or sautéed. Boiling it seems like a bit of a waste of a food prized for its flavor.
"At every level, from the microcellular to the psychological, exercise not only wards off the ill effects of chronic stress; it can also reverse them. Studies show that if researchers exercise rats that have been chronically stressed, that activity makes the hippocampus grow back to its preshriveled state. The mechanisms by which exercise changes how we think and feel are so much more effective than donuts, medicines, and wine. When you say you feel less stressed out after you go for a swim, or even a fast walk, you are."

"we sometimes lose sight of the fact that the mind, brain, and body all influence one another. In addition to feeling good when you exercise, you feel good about yourself"
Reading this book opened a door out of depression for me using the prescribed medicine, which is exercise and definitely wasn't easy.
As someone who's never smoked, but has stood next to people who have, I would guess it does quite the opposite. I imagine most people who don't smoke think this.
The first times you do it, it feels pretty good. Really good, in fact. However, like any drug, you develop a tolerance and a dependence. Before long, you require it to feel normal, not to feel good.
