The Claim
Chronic overproduction of cortisol results in adrenal exhaustion, which impairs the body's capacity to initiate an appropriate stress response when required.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If your body makes too much cortisol for too long, your adrenal glands can get worn out and stop working well when you actually need to handle stress.
See the scientific wording
Chronic overproduction of cortisol leads to adrenal exhaustion, impairing the body's ability to mount a stress response when needed.
What the research says
2 studiesThe study shows that when young zebrafish are made to produce too much cortisol for a long time, their bodies become worse at responding to new stress, just like the claim says happens in people.
Study: The hypothalamo–pituitary–adrenal axis in chronic fatigue syndrome and fibromyalgia syndrome
The study looks at people with long-term stress-related illnesses and finds their bodies produce less cortisol over time, which matches the idea that constant stress can wear out the body's stress response system.
