Flying After Diving: A Risky Combination
Chris Province Jul 29, 2024
Flying immediately after diving is strongly discouraged.
The reason for this is the risk of decompression sickness (DCS), also known as "the bends." When you dive, nitrogen from the air you breathe is absorbed into your body tissues. As you ascend, the pressure decreases, and this nitrogen needs time to be released through your lungs.
Flying after diving can accelerate this process, increasing the risk of nitrogen bubbles forming in your bloodstream and tissues. These bubbles can cause pain, paralysis, and even death.
General Guidelines:
- Single no-decompression dive: Wait at least 12 hours before flying.
- Multiple dives or repetitive dives: Wait at least 18 hours before flying.
- Decompression dives or technical diving: Wait substantially longer (consult with a dive professional).
It's important to note that these are minimum guidelines. Many experts recommend waiting a full 24 hours after any dive before flying.
Additional Factors:
- Altitude: Flying to higher altitudes increases the risk of DCS.
- Dive profile: Deeper or longer dives increase the risk of nitrogen absorption.
- Individual factors: Age, health, and medications can influence your susceptibility to DCS.
If you experience any symptoms of DCS after diving, such as joint pain, fatigue, or difficulty breathing, seek medical attention immediately.
