Most people cycle through a small set of familiar places. Research in human mobility suggests that, at any given time, our regular lives revolve around about 25 locations. This pattern seems stable even as the specific places slowly change with life events.
A separate line of research links variety in daily movement with better mood. Using smartphone GPS and short mood check-ins, scientists found that days with more varied movement and more novel stops tend to be followed by higher positive mood. The effect is not just about traveling farther. What matters most is exposure to new and different surroundings, including areas with different social and economic features.
Brain imaging helps explain why novelty feels good. People who showed stronger functional connections between the hippocampus, a region involved in memory and novelty, and the striatum, a region involved in reward, showed a stronger link between diverse daily experiences and positive mood.
The strongest evidence to date comes from young adults, and later work in adolescents shows the same pattern. Taken together, these findings suggest a simple idea that many can use. Add small doses of new places to your routine. Seek out streets, parks, or neighborhoods you have never tried. Variety appears to support learning and well-being.
Nature Neuroscience – Association between real-world experiential diversity and positive affect relates to hippocampal-striatal functional connectivity – 2020
Using smartphone GPS tracking, mood sampling, and brain imaging in young adults, the study shows that greater day-to-day variety in locations and exposure to novel and socio-demographically diverse areas are linked to higher positive mood. Connectivity between hippocampus and striatum moderates this link.
Nature Human Behaviour – Evidence for a conserved quantity in human mobility – 2018
Analysis of long-term mobility traces from tens of thousands of people finds that individuals typically maintain a stable set of about 25 familiar places at any given time, even as the set evolves, and this pattern relates to social network size.

In adolescents and young adults, greater daily exploration measured with roaming entropy is associated with higher positive mood and larger social networks, replicating adult findings and showing developmental increases in exploration.
