According to Wikipedia, “Hygiene” refers to the set of practices associated with the preservation of health and healthy living. The word seems to be used almost exclusively in the context of our material body, but the basic idea can be extended to the field of our mental well-being. For instance, one can ask questions such as what kind of information we should absorb, what is the proper amount and timing for that in-take, and wether the concepts of fasting can be applied to our mind.
I like this notion of hygiene. I frequently refer to co-workers skills/reliability with their Calendar (onto which we book meetings and organize work) as their “Calendar Hygiene.” Similarly, to their ability to notice and respond appropriately to e-mail (which implies an ability to correctly filter junk, along with at least a loose alignment on what is “not junk”) with the hygiene term.
