We know a fit body fosters a fit mind, but some types of exercise are more effective at sharpening memory function than others. In short, a treadmill is good, walking outside is better, bushwalking is best. “Getting outdoors is healthy for the brain because as you navigate the three-dimensional world you’re strengthening the hippocampus, which evolved for geolocation, for navigation,” says Dr Levitin. “Turns out it’s also the seat of all your memories. But it didn’t evolve to remember the lyrics of your favourite songs or your anniversary date, it evolved for navigation, and the greatest thing for memory is navigation.”
