Q: Why can't I get a certificate to go scuba diving because of asthma?
A: Unfortunately there is real danger of an asthma attack with scuba diving.
Diving gas is dry and, when released through a small valve, causes a cooling effect. A diver inhales a cold and dry air mixture, which is potentially very dangerous for people with asthma. The heavy exertion may provoke exercise-induced asthma, and the accidental inhalation of salt or fresh water can produce coughing and airways narrowing by direct irritation. The general stress and anxiety of diving may also add to the situation, setting the scene for a very serious attack of asthma.
