Want to live longer? Reduce your risk of cancer? And heart disease? Then cycle to work, say scientists. The biggest study into the issue linked using two wheels with a halving of the risk of cancer and heart disease. The five-year study of 250,000 UK commuters also showed walking had some benefits over sitting on public transport or taking the car. The ... study compared people who had an active" commute with those who were mostly stationary. Overall, 2,430 of those studied died, 3,748 were diagnosed with cancer and 1,110 had heart problems. But, during the course of the study, regular cycling cut the risk of death from any cause by 41%, the incidence of cancer by 45% and heart disease by 46%. The cyclists clocked an average of 30 miles per week, but the further they cycled the greater the health boon. Walking cut the odds of developing heart disease but the benefit was mostly for people walking more than six miles per week. "This is really clear evidence that people who commute in an active way, particularly by cycling, were at lower risk," Dr Jason Gill, from the University of Glasgow, told the BBC News website. People who combined cycling and public transport in their commute also showed health benefits. Clare Hyde from Cancer Research UK said: "This study helps to highlight the potential benefits of building activity into your everyday life. "You don't need to join a gym or run the marathon. "Anything that gets you a bit hot and out of breath ... can help make a difference."
