Can I dive if I have asthma?

The airway of an asthmatic gets constricted due to certain situations or certain stimuli. Extreme stress and anxiety cause the majority of asthma attacks. During such attacks, breathing becomes almost impossible as the airways constrict and the air becomes unable to move throughout the lungs. Scuba divers breathe compressed air, which is denser and consequently demands more effort to inhale for the air on the surface. The deeper you go, the more difficult it gets. As a recreational diver, you might not notice but due to compressed air, you might experience difficulties. Hence this resistance affects the asthmatic who already has constricted lungs and that can lead to a potential disaster. Scuba diving gives you the possibility to breathe underwater and it stimulates the production of adrenaline, which causes the heart to beat slightly faster and as a consequence, the breathing becomes heavier. All together the result could be catastrophic. A serious dive centre will not accept an asthmatic for his/her own safety.
