## Harvard Study Finds Daily Steps Help Brain
A Harvard study published in Nature Medicine shows walking over 3,000 steps daily may slow cognitive decline in older adults.

> The 14-year study suggests modest daily walking may slow tau buildup and cognitive decline in older adults with elevated amyloid.
## Study Tracks Step Counts Over 14 Years
Researchers examined 296 adults aged 50 to 90 using pedometers to sort them into four activity groups.
## Step Counts Linked to Slower Cognitive Decline
Participants walking 3,001 to 5,000 steps daily had 40% less cognitive decline than those walking fewer steps.
## Moderate Activity Shows Stronger Benefits
The moderate-activity group (5,001 to 7,500 steps) experienced 54% less cognitive decline than the inactive group.
## Active Group Had 51% Less Decline
The active group (over 7,500 steps) experienced 51% less cognitive decline than the inactive group over nine years.
## Thresholds for Cognitive Impairment
The inactive group reached cognitive impairment in about 6.5 years, while the moderate group reached it in 13.6 years.
## Benefits Plateau at 5,000 Steps
The study found benefits for cognitive health leveled off at around 5,000 to 7,500 steps per day.
## Key takeaway

A Harvard study shows older adults who walk over 3,000 steps daily experience 40% less cognitive decline than those who walk fewer steps.
