Salivary Cortisol Tracking
Saliva tests estimate cortisol rhythms at home. Trends in awakening response and evening levels matter more than any single reading.
Salivary cortisol tracking samples spit at waking, pre-bed, or after stressors to estimate free cortisol without blood draws. The cortisol awakening response should peak within thirty to forty-five minutes of waking; flat or exaggerated curves can reflect burnout, shift work, or chronic stress in research.
Home kits vary in quality—trends beat single points.
Common questions
-
When should you measure salivary cortisol?
Common protocols sample immediately on waking and thirty to forty-five minutes later, sometimes adding evening. Use the same clock times daily for comparable trends.
