While working in a so-called "high stress" occupation, where being under stress is a daily routine, for myself I lose track of the "stressmeter", and do not realize that there is a lot of stress present. We can become so enveloped in what we're doing that we do not realize the actual amount of stress, which could indeed be at an unhealthy level. Are ther any tools that could be used to allow such a person to gauge how any unnoticed stress may actually be having a detrimental effect on them?
