Based on the provided sources, cycle commuting is strongly associated with significant health benefits.

An 18-year study of 82,297 Scottish adults found that commuting by bike was linked to a lower risk of all-cause mortality, hospitalization, cardiovascular disease, cancer mortality, and better mental health compared to sedentary commuting. This study indicated that cyclists had a 47% lower risk of death for all causes, a 24% lower risk of hospitalization for cardiovascular disease, and a 51% lower risk of death from cancer compared to non-active commuters. Cyclists also saw a 10% lower risk of all-cause hospitalizations and a 20% lower chance of needing a mental health prescription. A separate 5-year UK study involving 263,450 commuters reported that regular cycling cut the risk of death from any cause by 41%, and the incidence of cancer and heart disease by 45% and 46% respectively. Individuals who did not cycle to work experienced a 39% higher mortality rate than those who did. Walking to work was also found to extend lives, though to a lesser extent than cycling.

Cycling is highlighted as a practical and sustainable way for many people to increase their daily physical activity. It can help protect against serious conditions such as stroke, heart attack, some cancers, depression, diabetes, obesity, and arthritis. Regular cycling stimulates and improves the heart, lungs, and circulation, thereby reducing the risk of cardiovascular diseases. Steady cycling burns approximately 1,200 kilojoules (300 calories) per hour. British research suggests that cycling for half an hour daily can lead to burning nearly five kilograms of fat over a year. The health benefits gained from the physical activity of active transportation are considered to outweigh the risks associated with air pollution exposure in most situations. Notably, motorists consistently experience the highest exposure to air pollution.

While large studies show strong associations, acknowledging potential factors that might influence findings is important, as conclusively proving causality can be complex. However, researchers perform statistical adjustments to account for confounders. Such scientific studies provide crucial data beyond common sense that can inform public health strategies and policy decisions. For instance, family physicians can encourage active transportation through patient education and community and policy advocacy, including promoting safe cycling infrastructure like separated bike lanes.

Cycling can also contribute to weight loss by burning calories, especially when combined with mindful eating. However, diet plays a significant role, and cycling alone may not be enough to overcome poor eating habits. Even low-intensity biking done daily can offer health benefits. Beyond physical health, cycling is associated with mental health benefits, stress reduction, increased energy, and other benefits like saving money on gym memberships and gaining a better sense of one's city. While traffic incidents pose a risk and cyclists are twice as likely to be hospitalized due to them compared to non-active commuters, overall hospitalization risk is lower for cyclists. Learning rules of the road and using hand signals are important safety practices.
