Mental States Are Physiological
Statement
Why it matters
Removes false mind/body split --- sleep, nutrition,
movement, and substance use directly affect mental state
Why Foundational
Foundational because the biological substrates of mental states are among the most robust findings in neuroscience — emotions correlate with neurotransmitter and hormonal patterns, depression and anxiety have measurable inflammatory and HPA-axis correlates, sleep deprivation produces specific cognitive and mood changes, dietary interventions affect mood through gut-brain axis and nutrient signalling. Removes false mind/body split: sleep, nutrition, movement, and substance use directly affect mental state. Realised's pillar architecture rests on this — "mental health" can't be addressed in isolation from sleep, diet, and physical practice because the systems are biologically coupled, not just metaphorically connected.
