Given that cycle commutes in cities can be blighted by air pollution and heavy traffic, that there is a reduction in stress levels by biking to work may seem counterintuitive. Or it could be that other commutes are even worse. The study was done in Montreal on 123 employees at an information technology company and it was small – only 25 were cyclists. This is actually more than the country’s national average – only 6% of Canadians cycle to work. In Britain about 4% of commutes are on bikes. In contrast, in Copenhagen, which has prioritised cycling so that no car or bus can travel faster through the city than a bike, about 40% of commuter trips are by bike.
