We haven't adopted as many practices from other religions. We eventually (1800s) adopted regular washing from Islam, but adoption was slowed by its taint of foreignness, much to the chagrin of millions of people who died of disease. The stretching aspects of yoga became mainstream within the last 50 years. Meditation and yoga breathing are still exotic. Perhaps some day they won't be, and our descendants will wonder how people from our era stayed sane without daily meditation.
The https://en.wikipedia.org/wiki/Art_of_Living_Foundation teaches meditation and yoga breathing worldwide, including regular classes in the Bay Area, if you want to try it yourself.
