A major study has found that cycling to work can significantly reduce the risk of cancer and heart disease. The research, which tracked 250,000 UK commuters over five years, revealed that regular cycling cuts the risk of death from any cause by 41%, the incidence of cancer by 45%, and heart disease by 46%.
The study, published in the British Medical Journal, compared those who had an 'active' commute with those who were mostly stationary. Cyclists averaged 30 miles per week, but the health benefits increased with distance. Walking also reduced the risk of heart disease, particularly for those walking more than six miles per week.
Dr Jason Gill from the University of Glasgow said the findings provide clear evidence that active commuting, especially cycling, lowers health risks. He noted that cycling becomes effortless once integrated into the daily routine, unlike going to the gym. The study also highlighted the need for better infrastructure, such as bike lanes and workplace showers.
While the study could not determine a direct cause-and-effect relationship, the benefits persisted even after adjusting for factors like smoking, diet, and weight. Researchers suggest that cycling may reduce cancer risk through lower body inflammation and leanness, rather than weight loss alone. Clare Hyde from Cancer Research UK emphasised that any activity that gets people slightly out of breath can make a difference.
