Surprising Findings
Hair cortisol levels are a validated biomarker for long-term stress in CKD patients and correlate directly with kidney and heart disease severity.
Most people think cortisol is only measured in blood or saliva—this shows long-term stress can be measured in your hair, like a biological diary.
Practical Takeaways
Practice daily stress-reduction techniques like breathwork, mindfulness, or walking in nature—these may help lower cortisol and reduce inflammation over time.

People with chronic kidney disease often have abnormal stress hormone patterns—low in the morning and high at night—and this seems linked to more body inflammation, trouble with metabolism, and reduced response to stress hormones, which might make their kidney disease worse over time.
When your body is under long-term stress, it releases too much of a hormone called cortisol, which can make your body more inflamed, slow down skin and tissue repair, and lower your metabolism and thyroid activity.
People with chronic kidney disease tend to have higher levels of certain body chemicals that signal cell damage, and the worse their kidney function is, the higher these chemicals are—these chemicals may also mean their kidneys are getting worse faster and they’re more likely to have heart problems.
People with long-term kidney problems tend to have higher levels of certain body chemicals that cause inflammation, and the worse their kidney function gets, the more these chemicals rise — this might be why their kidneys and heart keep getting damaged over time.
When someone has long-term kidney problems, it can trigger a chain reaction where stress, swelling, and hormone imbalances all get worse together, making the kidneys and the rest of the body more damaged over time.
