As a response to overwhelming demands, the Hypothalamus pituitary adrenal (HPA) axis produce a steroid hormone called Cortisol as a stress response essential for the fight-flight mode. Cortisol is vital for the body to overcome threats and function normally. However, long-term exposure to cortisol can cause health issues that manifest in our physical state (Blood sugar and cholesterol imbalances, higher blood pressure, increased risk of heart disease, impaired cognition and metabolism, inflammation, exhaustion, and other health issues) and mental state (eating disorder, depression, anxiety, nervousness).

CoHeal platform can sample the levels of cortisol in real-time from a saliva sample taken after wake-up, morning, noon, evening, and night, showing a full diurnal cycle.
