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.
