What it is
Cortisol is a hormone made by the adrenal glands and measured in blood, urine, or saliva depending on the test.[1,2]
Why it matters
It connects stress-axis physiology, glucose metabolism, blood pressure, immune tone, sleep timing, and adrenal-pituitary context.[1,2]
What it affects
- It can influence several downstream parameter families, making it a potential high-degree graph node.[1,2]
- Timing matters because cortisol changes across the day.[1,2]
Interpretation traps
- Testing method, timing, medications, pregnancy, illness, and stress context matter.[1,2]
- BioConst does not interpret personal cortisol results or diagnose adrenal disorders.[1,2]
