Young men who switch to cycling in Dublin have a high risk of crashing with other vehicles. A new study shows that a shift to cycling had an overall positive effect on health.
This study of more than 50 thousand city commuters was carried out by Trinity College and UCD.
While the report found that cycling helps to reduce conditions including heart disease, breast cancer and depression by up to 20 percent there were also some negatives.
Men in their 20s who made the switch have a high risk of collison with other vehicles with the risk going up the longer the journey.
The study recommends improving cycle lanes, introducing traffic calming measures in residential areas and more cyclist awareness for drivers.
