Mind & Mood
Where the exercise evidence is strong and the hormone talk is mostly invented.
Two things are true at once here. Exercise has a substantial, well-analysed evidence base for depressive symptoms: a network meta-analysis in the BMJ, not a wellness blog. And the hormonal vocabulary that dominates wellness content, cortisol faces, adrenal fatigue, dopamine detoxes, is largely fabricated.
These pages keep the strong claims and drop the invented ones. Nothing here is a substitute for treatment, and every page points towards help rather than around it.
