Can I scuba dive if I have asthma?

If you have asthma, you may be wondering if scuba diving is a safe activity for you. The answer is not a simple one, as it depends on the severity and control of your asthma.

Firstly, it’s important to understand that scuba diving involves breathing compressed air, which can cause problems for those with respiratory issues. However, many people with asthma are able to scuba dive safely with proper precautions and medical clearance.

Medical Clearance

Before you can scuba dive, you will need to obtain medical clearance from a doctor who is familiar with diving medicine. This doctor will assess your asthma and determine if it is well-controlled enough for you to safely scuba dive. They may also recommend a spirometry test to measure your lung function.

Severity of Asthma

The severity of your asthma will also play a role in whether or not you can scuba dive. If your asthma is mild and well-controlled with medication, you may be able to dive without any issues. However, if you have severe asthma or have had recent exacerbations, it may not be safe for you to dive.


If you do have asthma and are cleared to scuba dive, there are several precautions you should take to ensure your safety:

  • Always carry your inhaler with you on the dive
  • Inform your dive buddy and instructor of your asthma
  • Take extra care to monitor your breathing and air consumption
  • Limit the depth and duration of your dives
  • Avoid diving in cold water, which can trigger asthma symptoms
