There Are Two Completely Different Problems Here
When a client tells me they need to manage their stress, I first want to know which of two different things they mean. The word covers a range of experience, and what helps with one kind often does nothing for the other.
From what I have noticed working with clients, the useful question is not how much stress someone is under. It is what kind. Most stress management, and the industry built around it, does not make that distinction.
Hans Selye, the endocrinologist who spent decades studying the stress response, drew this distinction in the 1970s. He separated stress into eustress, from the Greek eu, meaning good, and distress. His core observation was that the stress response is not inherently harmful. What determines whether stress is damaging or not is not the intensity of the response but its nature, duration, and whether the person has the capacity to meet it.
Most stress management treats all stress as one problem. It is not.
What Good Stress Actually Is
Eustress is the activation that accompanies challenge, meaning, and engagement: the focus before a board presentation that matters, a deadline with real stakes, a difficult project that feels alive rather than depleting.
What differs is not the physical sensation but the relationship to what is producing it. With eustress, the challenge feels within your capacity and the outcome matters. What you feel reads as energy rather than threat.
It also resolves. When the demand passes, the system returns to baseline. The response was appropriate, it did its job, and it finished.
This kind of stress does not require management. It requires clarity about what is actually being demanded, whether the resources exist to meet it, and what the work means. When those are clear, a person who appears stressed is often functioning as they should.
