Mental health status in humans is associated with cortisol levels.
Not testedNo studies
Evidence is judged against each part on its own, so a study that tests one part never counts as a verdict on the whole claim.
What the research says
3 studies reviewedSupporting (3)
Cohort StudyHuman2026
The study found that in some teenagers, higher hair cortisol (a stress hormone) was linked to more anxiety or stressful life events, but not everyone showed this link. This supports the idea that mental health and cortisol are related, though the connection is not strong or universal.
Cross-Sectional StudyHuman2023
This study looked at people with mouth conditions and found that those with more anxiety and depression also had higher cortisol levels, supporting the idea that mental health is linked to cortisol in humans.
Cross-Sectional StudyHuman
This study found that people with higher morning cortisol levels were more likely to have anxiety, so it supports the idea that mental health and cortisol are linked in humans.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
