Whether you are an Olympic athlete competing in Vancouver or just a recreational athlete, studies show that mixing physical exertion and cold weather may trigger asthma symptoms. It seems that exercise induced asthma is common among people who do workout in the cold.
The combination of physical exertion and cold, dry air may cause issues, but they do not have to eliminate your winter time activities. To prevent asthma symptoms from occurring, a thorough warm-up is prescribed before activity. If you know that you already have asthma, make sure to carry your inhaler.
