You’ve just had an incredible dive. You explored stunning coral reefs and spotted some vibrant marine life. Now you’re all set for whatever’s next on your itinerary. But before you pack everything for the next flight, it’s important to ask: how long after SCUBA diving can you fly?
Flying too soon after SCUBA diving can be risky, and no one wants their dream vacation cut short by something that could have been avoided. But don’t worry– by the end of this blog, you’ll be familiar with some diving and flying rules as well as know exactly how long to wait before catching the next flight!
Flying after SCUBA diving isn’t just a matter of convenience, it’s a safety issue. Imagine this: Your body is like a sponge when you dive. It soaks up extra nitrogen from the compressed air in your SCUBA tank. That’s totally fine while you’re underwater, but things change when you return to the surface. Your body needs time to release that extra nitrogen. And flying messes with that process.
The problem is that airplanes have lower pressure than sea level. This sudden change in pressure can cause nitrogen bubbles to form in your body. The result? A serious condition called Decompression Sickness (DCS), also known as “the bends.”
Ever wondered why can’t you fly after diving? The answer is Decompression sickness, also known as “the bends”. It happens when nitrogen bubbles get stuck in your tissues and bloodstream. These bubbles can get stuck in your joints, muscles, and in critical areas like your brain or spinal cord. Symptoms range from mild joint pain to paralysis to even death in extreme cases. Yep, it’s that serious!
When diving deeper and longer, your body absorbs more nitrogen. And, if you fly too soon after diving, the pressure change during the flight can cause the nitrogen to form bubbles. It’s very similar to opening a can of soda that’s been shaken up.
Even in a pressurized airplane cabin, the pressure is lower than at sea level. This pressure reduction can cause any remaining nitrogen in your body to come out too quickly. It’s like surfacing too quickly all over again, but this time you’re 30,000 feet in the air!
So, how long should you wait between SCUBA diving and flying? The answer depends on your diving profile and how much nitrogen your body has absorbed.
If you’ve completed a single, no-decompression dive (meaning you didn’t have to make any mandatory stops on your way up), it’s recommended to wait at least 18 hours before flying. This gives your body plenty of time to safely release most of the extra nitrogen.
If you’ve done multiple dives in a day or dives that required decompression stops, you should wait 18 to 24 hours before boarding a plane. Multiple dives mean more nitrogen and more nitrogen means a longer wait time to be safe.
If you’ve been diving with nitrox (a gas mixed with higher oxygen and lower nitrogen), your body absorbs less nitrogen. That’s good news, right? Well, you still need to follow the guidelines: 12 hours for single dives and 18 to 24 hours for multiple or deeper dives. Better to be safe than sorry!
Flying after diving isn’t just about sticking to a clock. A few other factors can influence your risk level and wait times.
The deeper you dive, the more nitrogen your body takes in. So if it’s beyond 30 meters (100 feet), you’ll want to lean towards the 24-hour wait time. It’s just extra peace of mind.
Your health and fitness level matter, too! People with higher body fat percentages tend to retain more nitrogen, which can increase the risk of DCS. And if you’re dehydrated or fatigued, your body takes longer to eliminate nitrogen.
When it comes to diving and flying rules, it’s best to trust the experts. Let’s see what leading organizations have to say.
According to DAN, divers should follow these guidelines before flying:
PADI’s advice is right in line with DAN’s. They also emphasize sticking to your dive computer or table’s recommendations. These are designed to give you personalized guidance based on your specific dives.
Following the recommended wait times is crucial, but here are some extra tips to help you stay safe and enjoy your diving and travel experience to the fullest
Now that you have the answer to “how long after SCUBA diving can you fly?”, you can dive with peace of mind. It is truly an unforgettable adventure, but safety always comes first. Just remember to follow the recommended wait times before flying to avoid any health risks. That’s all from us.
