CYCLING TO WORK CUTS CANCER AND HEART-DISEASE RISK NEARLY IN HALF

A five-year study of 260,000 men and women in the UK found that bicycling to work every day reduced their risk of dying by more than 40 percent compared to commuters who drove or used public transport. In addition, the risk of developing cancer fell by 45 percent, and of being diagnosed with heart disease by 46 percent.

"This is really clear evidence that people who commute in an active way, particularly by cycling, were at lower risk," says Jason Gill, a physician-researcher at the University of Glasgow and corresponding author of the study.

Walking to work had a similar but smaller protective effect, probably because people who used bicycles for their commute exercised longer and more intensely than walkers. 

The powerful protective effect of active rather than passive commuting held up even when the researchers controlled for known risk factors such as smoking, weight and diet.

One benefit of bicycling to work, the researchers point out, is that unlike going to the gym or planned workouts, commuting becomes a no-willpower-needed habit. "You need to get to work every day, so if you build cycling into the day it essentially takes willpower out of the equation," says Gill.
