Lately I hear a lot of use of the word "physiology" to mean the current state of your body; posture, heart rate, thoughts, etc. For example, "Manage your physiology to stay focused at work" would mean sit upright, shoulders back, breathe slowly, and other such physical changes we can control that are conducive to better focus and comfort.
I'm pretty sure this is improper use blown into a buzzword; physiology is the biological study of how organisms function.
Is the proper word "physicality"? Is there another word to summarize "physical state" in this context?
