We also cover what the data says about:* Dementia risk, which continues to fall all the way to 8,000–10,000 steps* Depression, where the relationship is almost linear - the more you walk, the better you feel* Type 2 diabetes, falls, and why walking protects your health even beyond weight controlWe also touch on a new Nature Communications study showing that intensity may matter more than we thought. Just 1 minute of vigorous activity could offer the same benefit as 50–150 minutes of light activity.
