A salivary measure of your body's active stress hormone one hour after waking, showing whether the morning cortisol surge is resolving on schedule.
This sample captures cortisol 60 minutes after waking. In a healthy pattern, cortisol should have peaked at around +30 minutes and begun to decline by this point. In healthy adults, the +60 minute value should approximate the waking level (S1).
If cortisol is still rising at +60 minutes rather than falling, it may suggest a delayed or prolonged cortisol awakening response. If cortisol has dropped well below the waking value by this point, it may indicate a rapid decline. Both patterns gain meaning when interpreted alongside S1 and S2, because the three morning samples together define the shape of the cortisol awakening response.
The +60 minute sample confirms that the cortisol awakening response is resolving normally. When it approximates the waking level, it suggests the HPA axis fired appropriately and is now settling back to its daytime trajectory. Because the CAR is relatively distinct from later components of the daily cortisol rhythm, this sample sits at the boundary between the morning surge and the gradual daytime decline.
The CAR and the remainder of the daily cortisol curve should be interpreted separately and then brought together to determine the overall presence and severity of any HPA axis issue. You can have a normal CAR while the rest of the daily pattern is high, low-normal, or low. Compare this value with the cortisone reading at the same time point: when they diverge, cortisone may offer a more reliable picture of what cortisol is doing in your blood.
Because this value is shaped by the same HPA axis dynamics as the waking and +30 minute samples, the interventions overlap. Foundational HPA axis support (B vitamins, vitamin C, adaptogens, blood sugar regulation), stress reduction, parasympathetic nervous system support, calming herbs, and sleep hygiene practices all influence the morning cortisol curve. If the +60 minute value is persistently elevated, it may be worth evaluating for ongoing stressors, blood sugar instability, or pain that is sustaining cortisol output beyond the normal morning window.
