Is scuba diving hard on lungs?
Can I be seriously hurt while scuba diving? Yes.

What are the risks of scuba diving?

Can you scuba dive if you can’t swim?

Do you need a bronchodilator for scuba diving?
The asthmatic should not need more than occasional bronchodilators, i.e. daily usage would be a disqualifying factor, but inhaled steroids/cromoglycate/nedocromil are permissible. During the diving season he/she should take twice daily peak flow measurements.
Why do scuba divers have to exhale so much?
The air that divers breathe is compressed by the pressure of the water. Compressed air is denser than air on the surface and therefore already features an increased breathing resistance (takes more effort to inhale and exhale).
Should asthmatics not scuba dive?
However, such a broad prohibition flies in the face of reality, since it includes a large group of people with a history of asthma who, in fact, dive often and without any problem. On the other hand, any asthmatic who is constantly wheezing and coughing should obviously not scuba dive.

Should I scuba dive with allergies?
In general, individuals with environmental allergies may dive safely. Only during severe flare-ups should the symptoms preclude the safe use of scuba equipment. The diver must be able to equalize pressure in the middle ears during descent; mucous plugs preventing drainage of the sinuses will keep the diver out of the water.
