Not surprisingly, it turns out that walking or biking to work improves our psychological well-being. Taking transit had a similar positive effect over driving.
Highlights drawn from this longitudinal survey from the UK show that:
Compared to driving, well-being was higher when using active travel or public transport.
Use of active travel reduced the likelihood of two specific GHQ12 psychological symptoms.
Switching from car driving to active travel improved wellbeing.
Well-being increased with travel time for walkers, but decreased for drivers.
