Why If I Dive I Can’t Travel by Air?

Have you ever wondered what happens in your body after diving and why it’s crucial to wait before flying?

For many, scuba diving is a magical experience that offers the opportunity to explore an underwater world full of life and color. However, this aquatic adventure comes with certain responsibilities, especially when it comes to traveling by plane after a dive. In this article, we’ll break down the science behind nitrogen desaturation, the risks associated with flying after diving, and the safety recommendations you should keep in mind to enjoy your dive trips worry-free.

 


 

The Science of Nitrogen Desaturation

When you dive, you breathe compressed air, which means you inhale a mixture of gases, including nitrogen, at a pressure greater than sea level. At greater depths, nitrogen dissolves in your body’s tissues and fluids. This process is normal and essential for diving, but it also means that your body retains a considerable amount of nitrogen that must be safely released upon returning to the surface.

  • What is Desaturation? Desaturation is the process by which dissolved nitrogen is removed from the body. This occurs naturally when ascending, but how quickly nitrogen is released can be critical. If you fly too soon after a dive, the pressure change can cause nitrogen to expand rapidly, generating bubbles in your bloodstream or tissues, which can result in serious health problems.

 

 


 

Risks of Flying After Diving

The main risks associated with flying immediately after diving are related to decompression sickness. Here are some of the most significant risks:

  1. Decompression Sickness (The Bends): This condition occurs when nitrogen bubbles form in the body by depressurizing too quickly. Symptoms may appear hours or days after the dive and include:
    • Joint pains: Often described as severe pain, similar to arthritis.
    • Neurological problems: This can include confusion, dizziness, and in severe cases, paralysis or loss of consciousness.
    • Shortness of breath: This can be the result of bubbles blocking blood flow to the lungs.
  2. Unexpected Symptoms: Some symptoms of decompression sickness can be subtle and difficult to identify. It’s crucial to keep an eye out for any discomfort you experience after diving, even if it’s been a while.
  3. Aggravating Conditions: People with certain medical conditions, such as cardiovascular or pulmonary problems, may be at higher risk of experiencing complications after diving and flying. In addition, factors such as dehydration and exhaustion can increase the likelihood of adverse effects.

Safety Recommendations

Diving organizations, such as the Divers Alert Network (DAN), provide clear guidelines on the wait time between the last dive and the flight:

  • Wait between 18 and 24 hours: This is the recommended range to ensure that nitrogen is safely removed from your body. Although 18 hours is the minimum time for shallow dives, it is advisable to wait 24 hours if you have dived to greater depths or done several dives.
How to Calculate Your Wait Time?
  1. Number of Dives: If you have done several dives in one day, your body will have absorbed more nitrogen. In this case, it is safer to opt for the longer waiting time.
  2. Depth of the Dives: The deeper the dives, the more nitrogen will dissolve in your body. Dives over 30 meters require additional waiting time.
  3. Type of Diving: If you have done a saturation dive or a technical dive, which involves extensive use of gas mixtures or deep dives, it is vital to wait at least 24 hours before flying.
What to Do During the Waiting Time?

While you wait, there are many ways to take advantage of that time to relax and enjoy your destination:

  • Explore the Island or Destination: Take the opportunity to get to know the place where you are better. Enjoy the local culture, visit historical sites, or engage in outdoor activities.
  • Snorkel: If you haven’t reached the time limit for diving, snorkeling in shallow water can be a great way to enjoy marine life without the risks associated with depth.
  • Stay Hydrated and Rest: Make sure you drink enough water and get adequate rest. This will help your body get rid of nitrogen more efficiently.
  • Reflect on Your Dives: Take some time to review photos from your dives, share your experiences with other divers, and learn more about the marine life you’ve encountered.

Additional Tips for Divers

  • Use a Dive Computer: These devices will help you monitor your dives and calculate the necessary desaturation time. Make sure to follow the recommendations they provide.
  • Consult a Certified Instructor: If you have questions about wait time or any other medical considerations, talk to your dive instructor or a medical professional who specializes in hyperbaric medicine.
  • Know Your Limits: It’s always best to err on the side of caution. If you’re not sure if you can fly after diving, choose to wait an additional amount of time.

 

 


Conclusion: The Importance of Diving Safety

Although it may seem like a simple hassle to wait before flying after diving, this measure is essential to protect your health and well-being. Nitrogen desaturation is a critical process that should not be taken lightly. Taking the time between your last dive and your flight not only reduces the risk of decompression sickness, but also allows you to fully enjoy the diving experience.
