Is there a mental health disorder related to a harmful lack of anxiety and stress?
Sociopaths (people with Antisocial Personality Disorder) report lower levels of anxiety and stress than the general population. Psychopathic traits tend to foster resiliency and are protective against anxiety.

I'm a board-certified psychiatrist. There is ample evidence in the literature (and basic psych textbooks) that sociopathy have low levels of harm avoidance, decreased physiological responses to stress, and lower overall reported anxiety and fear. There is evidence supporting this.

In fairness, this association has come into question and there are some newer studies that are reevaluating the association between anxiety and sociopathy. Anecdotally, I have never encountered an ASPD patient with comorbid anxiety. I’m sure they exist: I’ve just never seen it, and suspect that it’s rare.
