Key Takeaways

  • Individuals with mild to moderate asthma can safely participate in recreational scuba diving, but they should consult with a diving doctor first and discuss their limits and triggers.
  • Scuba diving with asthma carries risks of bronchospasm and airway obstruction, so it’s important to manage symptoms carefully and monitor lung function before and during dives.
  • Understanding decreased breathing capacity underwater is crucial for asthmatic divers, as recommended depth limits may need to be adjusted based on individual conditions. Proper management and monitoring are essential for a safe scuba diving experience.

The Safety of Scuba Diving with Asthma

Scuba diving with asthma raises concerns due to the risks of bronchospasm and airway obstruction. However, individuals with mild to moderate asthma can still safely enjoy recreational diving by discussing their limits and triggers with a diving doctor.

Risks and considerations

Diving with asthma has some risks. These need your attention before you jump into the water. You can get more wheezing and shortness of breath while diving. Small airways in your lungs can block up fast deep under water.

It is called bronchospasm or airway obstruction, it’s a big concern for asthmatic divers! Also, gas that we breathe gets denser as we go deeper under water which makes it hard to breathe for people with asthma.

To stay safe, take a lung function test called ‘midexpiratory’ before you dive. This shows if your lungs are ready for diving or not. So meet a diving doctor and talk about your asthma triggers before any dive!

Mild to moderate asthma

Individuals with mild to moderate asthma can still participate in scuba diving, although there are certain risks to consider. It is important for people with asthma to have a discussion with a diving doctor before diving.

This is because diving can trigger asthma symptoms in some individuals and it’s crucial to understand your personal limits and triggers. Scuba diving with mild to moderate asthma may increase the risk of bronchospasm or airway obstruction underwater due to decreased breathing capacity.

Therefore, it is essential to manage and monitor your symptoms carefully while enjoying this recreational activity.

Discussing limits and triggers with a diving doctor

It’s important for individuals with asthma who want to scuba dive to have a discussion with a diving doctor. This conversation will help determine their limits and triggers when it comes to diving.

The doctor can provide guidance based on the individual’s specific condition and concerns. By discussing these factors beforehand, it can help ensure a safer and more enjoyable experience while scuba diving.

Maximum Safe Depth for Scuba Diving with Asthma

A scuba diver with asthma explores a vibrant coral reef surrounded by a bustling atmosphere.

The maximum safe depth for scuba diving with asthma depends on understanding decreased breathing capacity underwater, recommended depth limits, and the importance of proper management and monitoring.

Understanding decreased breathing capacity underwater

When scuba diving, it’s important to understand that your breathing capacity decreases as you go deeper underwater. At a depth of 33 feet, the maximum breathing capacity for a normal diver is only 70% of what it is on the surface.

This means that if you have asthma, your lungs may be affected even more. It’s crucial to manage your asthma properly and monitor your lung function while diving. Following recommended depth limits can help ensure your safety and reduce the risk of breathing difficulties.

Make sure to consult with a diving doctor to determine what depth is safe for you based on your specific condition and triggers. By understanding how decreased breathing capacity underwater affects you, you can take steps to enjoy scuba diving while keeping yourself safe.

When scuba diving with asthma, it is important to be aware of the recommended depth limits for safety. At a depth of 33 feet underwater, the maximum breathing capacity of a normal scuba diver is only 70% of the surface value.

This means that individuals with asthma may have even lower breathing capacity at this depth. It is crucial to remember that decreased breathing capacity can increase the risk of complications and potential triggers for asthmatics.

Consulting with a diving doctor can help determine your safe limits and ensure proper management and monitoring while scuba diving with asthma.

The article “Discovering the Limits: How Deep Can You Safely Scuba Dive With Asthma?” provides valuable information on understanding these recommended depth limits. By taking precautions and following guidelines, individuals with mild to moderate asthma can still enjoy scuba diving within their safe depths.

Importance of proper management and monitoring

Proper management and monitoring are crucial when it comes to scuba diving with asthma. It’s important for individuals with asthma to have their condition well-controlled before attempting any underwater activities.

This includes taking prescribed medications as directed by a healthcare provider and following an asthma action plan. Regular check-ups and lung function tests can help assess the current state of the lungs and ensure they are in good condition for diving.

Additionally, proper monitoring during dives is essential to detect any signs of breathing difficulties or worsening symptoms. By closely managing and monitoring their asthma, individuals can enjoy the thrill of scuba diving while minimizing potential risks associated with the condition.


In conclusion, individuals with asthma can still enjoy scuba diving, but they need to be aware of the risks and limitations. It is important for asthmatics to consult with a diving doctor to determine their safe depth limits and manage their condition properly.

By taking proper precautions and closely monitoring their breathing, asthmatics can safely explore the underwater world while enjoying their passion for scuba diving.


1. Is it safe to scuba dive if you have asthma?

Yes, but there may be some risks of scuba diving with asthma. Keeping a check on lung function and managing asthma while diving are important.

2. What should asthmatic divers do before they go diving?

Before going underwater, asthmatics should take a pulmonary function test. This test will help them know about any breathing difficulties and scuba diving related impacts on their lungs.

3. How does the depth impact people with asthma when scuba diving?

Going deeper can lead to more pressure underwater which may affect an asthmatic’s lungs. Asthma and depth limits for scuba diving need careful study for safety reasons.

4. Can taking asthma medication help in safer dives?

Taking certain approved medications might help manage symptoms better during the dive; it is however important not to forget possible triggers and precautions relating to both, asthma as well as the intended water activity.

5. Why are predive evaluations so important for people with Asthma who want to Scuba Dive?

Predive evaluations are key since they look at how fit one’s airway system is for handling a dive – making sure that breathing problems like wheeze or midexpiratory obstructions aren’t lying in wait under increased pressure conditions.
