This... plus there’s a time element too. New challenges that one faces might be physiologically stressful, but if they are within your scope to meet and overcome, can also be incredibly motivating - aka ‘good stress’. In my view they become ‘bad stress’ if they are either prolonged (thereby wearing your resilience down) or due to your circumstances you have no power or opportunity to meaningfully meet and overcome them.
