Three mists. Three nervous system states. The right one depends on what's actually happening in your nervous system right now. Running hot, reactive, can't exhale? CALM. Heavy, foggy, can't initiate? FOCUS. Scattered, not quite present, going through the motions? GROUND. This page is the entry point for choosing between CALM, FOCUS, and GROUND—with the thirty-second diagnostic, the product science, and links to the full guides. State-first use builds more specific conditioned responses and produces more reliable results than time-first use.

FOCUS is formulated for adenosine-driven cognitive fog and scattered attention—the afternoon dip, the post-context-switch fragmentation, the moment your brain stops cooperating. Its compound profile targets adenosine receptors and the autonomic nervous system directly: 1,8-cineole (eucalyptus) for adenosine modulation and AChE inhibition, hesperidin/limonene (yuzu) for sympathetic suppression, mint for trigeminal activation. This is the full science behind it, and why it works differently from stimulants (modulation vs. blockade, no crash).

Deep work fails not because of poor time management but because of nervous system conditions. Sustained, concentrated attention requires a physiological state—low cortisol, reduced sympathetic activation, narrowed attentional focus—that most modern workdays actively undermine. These seven approaches build that state deliberately, before and during the work itself.
