The claimWhat Goldie actually said

Hawn, who has meditated since 1972, attributes much of her wellbeing and mental sharpness to the practice and has channelled it into neuroscience-informed childrens education. She states plainly that meditation thickens the cortex and that her brain feels stronger with age. Her framing leans on brain-imaging research she has discussed with neuroscientists.

Why it mattersWhy this matters for longevity

Millions try meditation expecting cognitive protection as they age.

It is a useful test case for separating correlation from causation in brain science.

The evidenceWhat the science says

An influential 2005 study found experienced meditators had increased cortical thickness in regions tied to attention and interoception, and a 2014 meta-analysis identified several consistently altered brain regions with a medium overall effect size.

What the evidence does not establish is causation: these studies are mostly cross-sectional, may reflect who chooses to meditate, and reviewers explicitly call for rigorous longitudinal trials before crediting meditation with thickening the cortex.

TakeawayThe honest takeaway

The practical lesson

Meditate for the well-documented calm and focus benefits, not on a promise of a measurably thicker brain.

SupplementsThe supplement angle: Omega-3 fatty acids

Support a habit, do not replace one

Omega-3 intake is studied for cognitive aging with mixed results, and it is best viewed as part of an overall diet rather than a substitute for mental-wellbeing practices.

Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
