Baselines and couplings

Every signal has a baseline (its value with no interventions). Every signal also couples to others — cortisol feeds glucose, dopamine feeds focus, etc.

Baselines

• Population averages by sex + age, modulated by your conditions + bloodwork
• Visible as the "flat line" before interventions kick in
• You can't edit baselines directly — change your profile instead

Couplings

• Cortisol → glucose (gluconeogenesis)
• Caffeine → adenosine → cortisol → glucose (cascade)
• Exercise → dopamine + serotonin (composite)
• Couplings are documented in the Bibliography
