Pillars Are Interdependent
Statement
Sleep, movement, nutrition, and mental health form a
coupled system --- deficits in one degrade the others
Why it matters
Realised's entire architecture rests on this --- you
can't fix sleep while ignoring the system it's embedded in
Why Foundational
Foundational because the systems-coupling has overwhelming evidence — sleep affects glucose tolerance, exercise affects sleep architecture, diet affects mood, mood affects movement, all four affect inflammation and HPA-axis tone. Sleep deprivation alone reduces testosterone, impairs glucose handling, increases inflammation, and degrades emotional regulation — a single deficit propagates across all four pillars. Realised's entire architecture rests on this: you can't fix sleep while ignoring the system it's embedded in.
