The Claim

Chronic activation of the hypothalamic-pituitary-adrenal (HPA) axis increases cortisol levels, which in turn increases systemic inflammation, suppresses collagen synthesis, and reduces thyroid function and metabolic rate.

How it works

In plain English

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.

Chronic activation of the hypothalamic-pituitary-adrenal (HPA) axis elevates cortisol, which increases systemic inflammation, suppresses collagen synthesis, and reduces thyroid function and metabolic rate.

  1. Study: Stress Pathways in Chronic Kidney Disease: Linking Cortisol, Oxidative Stress, and Inflammation

    When your body is under long-term stress, it releases too much cortisol, which can make your body more inflamed and slow down your metabolism—this study shows that’s exactly what happens in people with kidney disease, and the same process likely happens in others under chronic stress.
