A new study of over 135,000 people aged 45+ compared three groups: those who did no exercise at all, those who exercised in traditional ways, and those who engaged in gardening.
The result was clear:
- 28 % lower risk of cognitive decline
- 43 % lower risk of cognitive difficulties in everyday life
The researchers controlled for age, income, education, health status and lifestyle factors — so the effect came from the gardening itself.
Why does it work?
- Movement and energy expenditure explained 39 % of the protection.
- Reduced depression/stress accounted for 22 %.
- More fruits and vegetables in the diet also contributed.
Conclusion: 20 minutes in the garden provides tangible benefits for brain health.
