The Sleep & Stress Profile is an advanced saliva-based test that assesses the two key hormones involved in sleep regulation and stress response: cortisol and melatonin.
By measuring cortisol at multiple points across the day and night alongside melatonin, this profile provides insight into your natural hormone rhythms and how they may be affecting sleep quality, energy levels and stress resilience. Disrupted rhythms are commonly linked to poor sleep, unrefreshing rest and daytime fatigue.

Why choose this test?
The Sleep & Stress Profile provides a detailed assessment of how your body regulates sleep and responds to stress across the day and night. Rather than measuring a single hormone level, this profile evaluates daily hormone patterns, which are critical for healthy sleep, energy and recovery.
By assessing cortisol and melatonin at multiple time points, this test helps identify disrupted circadian rhythms that may contribute to difficulty falling asleep, staying asleep, unrefreshing sleep or persistent fatigue. It offers deeper insight into whether stress hormone timing, sleep hormone production or both may be affecting overall sleep quality and daytime function.
About these tests
Cortisol (Morning, Midday, Midnight):
Cortisol is the body’s primary stress hormone and follows a natural daily rhythm. Levels are typically highest in the morning to support alertness and energy, gradually declining throughout the day and reaching their lowest point at night. Measuring cortisol at multiple times allows assessment of whether this rhythm is balanced or disrupted, which can influence sleep quality, stress tolerance and daytime fatigue.
Melatonin (Morning, Midday, Midnight):
Melatonin is the hormone responsible for regulating the sleep–wake cycle. It normally rises in the evening to promote sleep and remains low during the day. Measuring melatonin at multiple time points helps assess whether production and timing are appropriate, as disruptions can be associated with difficulty falling asleep, poor sleep quality or altered sleep timing.
