Want to dive but have Asthma? It may be possible depending on your condition. These guidelines are from Divers Alert Network.
Recommendations and Guidelines
Whether an individual with asthma can safely scuba dive depends on the severity and control of their condition. Key recommendations include:
Consult a Physician: A thorough medical evaluation by a doctor familiar with diving medicine is essential. Pulmonary function tests, such as spirometry or a “6 minute walk test” may be performed to assess airway responsiveness.
Assess Asthma Control: Divers should have well-controlled, mild, and infrequent asthma symptoms. Diving is generally discouraged for those with recent symptoms, frequent attacks, or exercise/cold-induced asthma.
Medication Management: Divers should follow prescribed medication regimens, including the use of inhalers. Carrying a rescue inhaler and having it accessible on the dive boat or dive site is advised.
Pre-dive Precautions: Avoid diving if experiencing any respiratory symptoms, chest infection, or after a recent asthma attack.
Choose Suitable Environments: Warm water and calm conditions are preferable, as cold water and strenuous dives may increase risk.
Practical Tips for Divers with Asthma
Communicate openly with dive instructors and buddies about your condition.
Monitor your symptoms and use a peak flow meter if recommended by your doctor.
Avoid known asthma triggers before and during the dive trip (e.g., allergens, airborne seasonal respiratory infections).
Be cautious with physical exertion and practice controlled, slow breathing techniques.
• Have an emergency action plan in place in case of an asthma attack.
