A constant state of adrenalin arousel, although physically damaging, is often experienced as pleasant excitement and stimulation. And it is this that makes it most dangerous, because we can come to think of the arousal state as "normal" and to depend on the high it gives us to get anything accomplished. I believe there is a corresponding spiritual danger.

Becoming dependent on adrenalin arousal for the good feelings of life can create an association between spirituality and high arousal. In other words, one doesn't feel "spiritual" unless one is being stimulated by adrenalin arousal. Many expressions of spirituality have become linked to adrenalin arousal, and this can be very harmful. A great many of the true saints of God have found their peak spiritual experiences in quietness and solitude. But many modern "saints" look for it only in exciting challenges or emotional catharsis.
