The psychological benefits of walking or cycling to work come on top of the well-known physical health benefits.
In February of this year, the UK Office of National Statistics published a report that found UK citizens who walked to work had lower life satisfaction than those who drove to work. The report also found that cyclists were less happy and more anxious than other commuters.
The new study, however - which is published in the journal Preventive Medicine - contradicts this.
The team studied 18 years of data from almost 18,000 commuters in the UK aged 18-65. The data took in various aspects of psychological health including feelings of worthlessness, unhappiness, sleepless nights and capability of dealing with problems.
Factors that are known to affect well-being, such as income, having children, moving house or job, and relationship changes were also taken into account by the researchers.
The results suggest that people benefited from improved well-being when they stopped driving and started walking or cycling to work. Commuters reported that they felt better able to concentrate and "less under strain" if they used these methods of travel, rather than driving a car.
The researchers also point out that these psychological benefits come on top of the well-known physical health benefits associated with walking and cycling.
Even traveling on public transport was associated with greater psychological well-being than driving.
Commute time is 'also an important factor of psychological well-being'
University of East Anglia's Adam Martin, who was lead researcher on the study, says:
"One surprising finding was that commuters reported feeling better when traveling by public transport, compared to driving. You might think that things like disruption to services or crowds of commuters might have been a cause of considerable stress. But as buses or trains also give people time to relax, read, socialize, and there is usually an associated walk to the bus stop or railway station, it appears to cheer people up."
Commute time was also demonstrated to be an important factor of psychological well-being. "Our study shows that the longer people spend commuting in cars, the worse their psychological well-being," says Martin. "And correspondingly, people feel better when they have a longer walk to work."
Last month, another study from the UK, published in the BMJ, found that the health benefits of walking or cycling to work are also experienced by people who commute to work by public transport.
In that the study, the difference in percentage of body fat between public transport commuters and active commuters was found to be similar in both size and significance.
In 2011, Medical News Today looked at a study from the US, published in the journal Environmental Health Perspectives, which estimated a saving of $3.8 billion per year in avoided mortality and reduced health care costs if half of the short car journeys are replaced by bicycle trips during the warmest 6 months of the year.
The researchers behind that study also estimated that, in this scenario, 1,100 lives would be saved each year by improved air quality and increased physical fitness.
According to the US Census Bureau, 86% of workers currently commute by private motorized transport such as car, truck or van.
