What Is Asthma?

Asthma is a condition that affects the airways. The airways carry air in and out of your lungs. Asthma is caused by chronic inflammation and is oversensitive to certain triggers like an allergy, exercise, and stress.

Simply the reaction to the triggers causes the muscles of the tube walls to tighten up. Causing them to become narrow and leaving less room for air to flow in and out.

Then the lining of your airways starts to get swollen with sticky mucus is produced which clogs up the breathing passages. Causing difficulty breathing.

  • For at least 48 hours before diving, your peak flow is within 15% of your best value.

Factors To Consider To Dive With Asthma

With diving, they are a number of factors that could trigger an asthma attack. Before going diving these factors could trigger an attack.

Cold, Dry Air To Breathe

Cold, dry air is a common asthma trigger and can cause bad attacks. When cold air gets into your airways it can trigger an asthma attack with symptoms like coughing, shortness of breath, and tightness in the chest

And if hyperventilation starts to happen during the descent, it could cause the diver’s airway to narrow.

If you are diving in cold water this could cause the air from your tank to be cold, since you will be breathing through the mouth than the nose. Your body won’t have time to warm the air before it gets to your airways.

Stress Triggered

Stress is another major trigger of asthma. When you start to get stressed this can trigger an asthma attack with symptoms like coughing, shortness of breath, and tightness in the chest.

Stress causes the body to respond by releasing certain hormones triggered by the immune system. This causes the airways to narrow.

Strenuous Exercise

Scuba diving can be a good workout to a strenuous workout, the problem for asthma suffers is this can trigger an asthma attack. This attack causes shortness of breath, chest tightness, wheezing, and coughing.

This can be managed on land with an inhaler or relaxing for a while but underwater this may not be possible.

How Deep Should You Dive If You Are Asthmatic?

If your asthma is controlled and is not triggered by cold, exercise, or stress and your lungs work normally there is no depth restriction. Assuming you have talked with your doctor. The depth recommended is no deeper than 130 feet/40 meters.

To go scuba diving you don’t need to dive to some extreme depth of 30 feet, as most divers would agree that a dive to only 12 feet can be more interesting than 100 feet.

Wrapping Up

Finally, the decision of whether to dive or not is your decision. This should be make between you and your doctor. And you should inform the dive master. Simply, if your health is good overall apart from having asthma and cold air, panic or stress is not a major trigger for you, diving can be something that you could try.
