British researchers concluded a detailed investigation of the commuting choices, lifestyle behaviours and medical information of 260,000 adults and reported that cycling to work was associated with a 45 per cent lower risk of developing cancer, a 46 per cent lower risk of heart disease, and a 41 per cent lower risk of premature death from any cause, compared to those who drove or took public transport.
The link between moderate levels of activity integrated into daily routines and improved health outcomes has been shown before in many studies, although not usually with this large a population sample. Other studies have monetized the improved health outcomes, reporting that $1 invested in cycling infrastructure returns $10 to $20 annually in reduced future health care costs.
The bottom line? Cities that don’t invest in becoming bike friendly can expect reduced levels of population health and ever-escalating requests for health care spending, in addition to all the other foregone economic benefits.
