It is not worth compromising your safety — which could ruin more than your whole trip — because you or someone else is in a hurry to make the first dive. By submitting above, you agree to Scuba Diving's privacy policy. The concerns of heading to altitude too soon after diving are the same as those when you ascend from your dive too quickly because the same scientific principles apply: going to altitude takes you to an area of lower outside pressure, meaning residual nitrogen still dissolved in your blood can come out of solution as bubbles if the pressure reduction is not slow enough to let your body off-gas safely.
Staying at ground level before going to altitude is like doing a decompression stop. Deeper and longer dives will leave you with more residual nitrogen, thus requiring a longer pre-flight surface interval. The time you should wait relates directly to the pattern of diving completed. We recommend a general practice of allowing a surface interval of 24 hours or more before flying after diving. This should bring reasonable peace of mind and help to provide a buffer for unexpected problems, like a loss of cabin pressurization during flight.
Ultimately, it is better safe than sorry and almost every location has enough to entertain you for the final day. Alternatively, you can choose to follow the minimum guidelines established by DAN and the Undersea and Hyperbaric Medical Society for flying in commercial pressurized aircraft Sheffield and Vann :.
The vagueness of the post-decompression dive recommendation was to acknowledge that we did not have sufficient data to establish a firm guideline. This brings us back to the 24 hour recommendation. Planning conservatively is a good way to stay out of trouble. Given the variety of decompression algorithms now available for divers - some conservative but many fairly liberal - a healthy buffer represents inexpensive insurance. It is also important to remember that these guidelines apply to divers who have not experienced any DCS symptoms on the trip.
If you or a partner have experienced DCS symptoms during your dive trip, you should be medically evaluated, if possible, before flying. You can contact DAN to help connect you with appropriate resources or in case of emergency.
Just as we are taught not to "push the tables" in terms of depth and bottom times, it is a wise choice not to push flying after diving. Making your final dives more conservative and leaving an ample buffer between your last dive and your flight home is part of smart dive planning, a goal for all in the community. This is when we need to plan our dives around the flights, making sure we have enough time after diving before flying again.
While scuba diving, we absorb an excess amount of nitrogen due to the increased pressure at depth. Nitrogen takes time to naturally leave the body, which means an interval of time is required before any flight is taken.
Ascending to altitude in a plane after diving can bring on Decompression Sickness. This can happen when there is a decrease in atmospheric pressure as you ascend. We may still have small nitrogen bubbles in our bodies after a dive but not enough to cause any problems.
However, once we start ascending in a plane and experience that change in cabin pressure these nitrogen bubbles can start to expand and bring on symptoms of decompression sickness.
This is why an interval is needed before flying. This question brings up many different answers depending on who you ask and which agency you have trained with. There are also a few factors to consider to answer this question as well, such as how many dives were performed in the day and whether a decompression stop is required. As you can see this information is very conflicting, especially when planning your trip and booking your flights. So, which guideline should you follow?
The answer to this would be to follow the current DAN guidelines. Always check these details before booking your flight. As a diving instructor I would always try and allow 24 hours between my last dive and my flight time, just to be extra cautious.
As you can see, 18 hours would more than suffice before flying. Well yes, below is a list of things that you should not do directly after a dive. In these cases, you should wait for a few hours before proceeding with these activities. Altitude is not always flying. For example, you might live in an area surrounded by mountains that you need to go over on your journey to and from the dive site.
With PADI, going to altitude is considered m above sea level. Going above this altitude can cause pressure changes resulting in symptoms of decompression sickness.
Putting your body into a hot environment after diving, such as a hot bath, shower or even sauna can cause any nitrogen bubbles to expand within the body. This can bring on symptoms of decompression sickness. Try not to get cold on your dives wear enough exposure protection such as a thicker wetsuit and turn down the temperature in your shower to help avoid this happening.
You might be lucky enough to be diving in a location that also has massage parlours nearby. The temptation can be to get a massage just after you have finished diving to help soothe all those aches from carrying your equipment around. However, you should leave at least 3 hours between a scuba dive and a massage. During the massage process the manipulation of muscles and body tissue can cause problems with releasing nitrogen, again, this can lead to effects of DCS.
You may already have a regular fitness program and want to stick to this while on a diving holiday. Physical activity after diving, be it weight training, cardio, or even hiking can increase bubble formation within the body thus increasing the risk of DCS.
All dive trips that we offer day trips include 2 or 3 dives, and liveaboards are all multiple day trips with 2 — 4 dives per day. So the figure you want to remember is 18 Hours. If are booking a typical 4 day liveaboard to the Similan Islands for example, the final dive of the final day is normally before lunch, after which the boat is cruising back to the mainland.
So you are safe to fly by next morning. Be sure to check the itinerary of any trip you book so you know when the last dive will be, and you can plan flights accordingly.
There are of course other factors involved. A major factor in a hot country like Thailand is dehydration — make sure you stay well hydrated when you are on a dive trip. Read more here: Health and Fitness for Diving. Send An Enquiry. There is no problem with diving after flying. There is no increased risk of DCS if you arrive on a flight and head straight to the ocean — DCS is caused by high concentration of Nitrogen in the blood after diving which can become supersaturated and form bubbles at lower pressures.
Before you dive, you have a normal amount of Nitrogen in the blood. Make sure you drink plenty of non alcoholic fluids on a long flight to prevent dehydration. There is also a tendency for people to arrive in a hot country and head straight to the bar for a cold one. Please remember that alcohol contributes to dehydration, so take it easy on the beers!
We recommend that all divers have their own travel and medical insurance, as well as cancellation insurance. Be sure that your travel insurance policy covers scuba diving! However, prevention is better than cure, so dive safely, follow the rules, use tables and computers and stay healthy!
Or you can pay Baht per diving day when making a booking. Sunrise Divers is based at Karon Beach, Phuket. From Phuket and nearby Khao Lak there are liveaboards or day trips with dive sites and boats to suit all divers and all budgets.
