The prolonged accumulation of 'Heat' is an unhealthful condition. We might consider this to be like revving a car's engine and keeping your foot on the pedal while idling. Emotion is the powerful vehicle through which we interact with our perceived environments (some look within and some look without). Health though is a state of balance where no dis-ease may take root and persist because energy continues to flow and is not curtailed by inner fires.
The emerging science of Mind-Body Medicine might more aptly be called Emotional Medicine. Our thinking about such things is an after-effect of the root cause which is how we feel about such things. To master Life and Health is to master emotion and mastering emotion is not intellectual suppression but existential balance where emotional reactions do not occur. Imagine if Architecture could assist in the development of a sustained calm?
