I'm firmly of the opinion that a lot of wellness fads spring up fields like tech because its a field where traditional religious views are rarer. People latch on to these new belief systems that are like religion in most ways beside name. They all have a set of rigid rules to follow and rituals to perform, and they all have some type of self-denial or sacrifice as one of their core values. Fasting, temperance, Whole30, gluten free, even modern fitness culture all share elements of denying yourself things you enjoy or putting yourself through unpleasant situations in search of some kind of enlightenment or transcendence.
I often see the same people falling into fad after fad, first telling me how EMFs are poison and will be looked at like cigarettes in a decade, and how singing bowls realign my spirit, and trying to insist on the power of visualization can cure chronic pain. I'm curious what it is that causes this.
