1. Avoid Air Travel Too Soon

Flying after scuba diving can be hazardous due to the changes in pressure. During a dive, nitrogen builds up in your body tissues, and it needs time to dissipate. If you fly too soon after diving, you risk getting decompression sickness (also known as "the bends"), which occurs when nitrogen forms bubbles in your bloodstream due to a rapid decrease in pressure. To avoid this, wait at least 18 to 24 hours before flying.


The Divers Alert Network (DAN) has established guidelines for safe intervals between diving and flying, which vary depending on the type of dives conducted. Here's what you need to know:


For a single no-decompression dive, wait at least 12 hours before flying. This allows your body sufficient time to release the nitrogen that accumulates during diving.

For multiple dives per day or multiple days of diving, it's safer to wait at least 18 hours before flying. This recommendation considers the cumulative effect of nitrogen buildup over several dives.


For dives requiring decompression stops, you should wait at least 24 hours before flying. Decompression dives involve a higher risk of nitrogen accumulation, necessitating a longer surface interval.


Beyond these minimums, some divers choose to err on the side of caution by waiting 24 hours after any type of diving before boarding a plane. This additional time can be used to relax and explore other activities above water.


Additionally, dive computers may recommend specific no-fly times based on your diving activity, which should be followed to ensure safety. Always listen to your dive computer's guidance, and if in doubt, consult with dive professionals or medical experts.

2. Zip-lining and high altitude activities


Costa Rica has some of the best Ziplines in the world and ziplining is an activity that many visitors love to do, offering breathtaking views and an adrenaline rush. However, the high elevation typically associated with ziplining can be problematic after diving. When you scuba dive, your body accumulates nitrogen, which needs time to dissipate. If you ascend to a high altitude too soon after diving, the pressure change can cause nitrogen bubbles to form in your bloodstream, leading to decompression sickness.

To ensure your safety, wait at least 24 hours after scuba diving before ziplining or engaging in any activity that takes you to higher altitudes. This waiting period helps reduce the risk of DCS and ensures you can enjoy your ziplining experience without concern for your health.


Other High-Altitude Activities to Avoid After Diving

  • Parachute Jumping or Skydiving: These activities involve rapid altitude changes, which can increase the risk of DCS.

  • Paragliding: Paragliding typically takes place in mountainous regions or high-altitude areas, which could pose risks after diving.

  • Parasailing: Although this activity occurs over water, it often involves ascending to considerable heights, posing similar risks as other high-altitude activities.

  • Air Ballooning: Hot air ballooning takes you to significant altitudes, which can be dangerous if you haven't given your body enough time to release accumulated nitrogen.


By avoiding these high-altitude activities for at least 24 hours after diving, you significantly reduce the risk of decompression sickness and ensure a safer transition from underwater exploration to other exciting adventures.

3. Deep Tissue Massage

After scuba diving, many divers look forward to relaxing and unwinding. While massage can be a great way to ease tension, there are specific guidelines to follow when it comes to post-dive massages. The Divers Alert Network (DAN) offers insights into the risks and precautions divers should take regarding massage after scuba diving.


Deep tissue massage involves applying firm pressure to muscles and connective tissues. This type of massage can be beneficial for muscle recovery, but after diving, it carries certain risks:


Increased Blood Flow: Deep tissue massage stimulates blood flow, which can lead to the formation of nitrogen bubbles. If these bubbles become trapped in tissues or enter the bloodstream, it can result in decompression sickness (DCS).


Muscle Soreness: Deep tissue massage can cause muscle soreness, which might be mistaken for symptoms of DCS. This misdiagnosis could lead to delayed treatment and potentially more severe complications.


Given these risks, it's recommended to avoid deep tissue massages for at least 12 hours after scuba diving. This waiting period helps ensure that any nitrogen remaining in your body has had time to dissipate, reducing the risk of bubble formation.


Gentle Relaxation Massages: Generally Safe


While deep tissue massage can be risky, gentle relaxation massages are typically considered safe after diving. These massages use lighter pressure and are less likely to increase blood flow to the extent that would cause bubble formation. If you're looking for a way to relax after a dive, a gentle massage can be a good option.


It's still essential to monitor your body for any unusual symptoms, such as joint pain, dizziness, tingling, or fatigue, as these could indicate decompression sickness. If you experience these symptoms, seek medical attention immediately and avoid any form of massage until you've been cleared by a medical professional.


5. Alcohol Consumption

After scuba diving, it's best to avoid alcohol. Alcohol dehydrates the body and if you indulge in drinking alcohol, your body will begin to dehydrate faster—and dehydration increases the risk of decompression sickness (DCS). Dehydration can exacerbate the effects of decompression sickness, leading to headaches, dizziness, and other health complications. Stick to water or sports drinks to replenish your fluids and electrolytes. And Costa Rica has the best smoothies in the world so go to your local restaurant and get one of those delicious smoothies !


6. Avoid Strenuous Exercise

Diving is physically demanding, so it's important to allow your body time to recover. Engaging in intense workouts or heavy lifting can increase the risk of decompression sickness by encouraging nitrogen bubbles to form. Instead, focus on light stretching or a leisurely walk to keep your body active without overexerting it.


7. No Hot Baths or Hot Tubs

While a hot bath or hot tub might sound appealing after a dive, it’s best to avoid them. The heat causes blood vessels to dilate, which can increase the formation of nitrogen bubbles in your bloodstream, potentially leading to decompression sickness. Instead, take a warm shower or relax in a cool environment to let your body naturally adjust to post-dive conditions.


8. Avoid Tight Clothing or Accessories

Wearing tight clothing or accessories like belts, watches, or jewelry can restrict blood flow and increase the risk of decompression sickness. This is because the restricted areas can create pockets where nitrogen bubbles can form. Opt for loose-fitting clothing after diving to ensure proper blood circulation.


9. Refrain from Diving Again Too Soon

While the thrill of diving might leave you eager for more, diving multiple times in quick succession can increase your risk of decompression sickness. If you plan on doing multiple dives in a day, make sure to follow recommended safety intervals between dives. Each dive computer has a plan dive mode. If you do not remember how to use it then ask our experienced guides to help you plan your next dive. For those doing repeated dives over several days, take a day off to let your body recover.

10. Don't Ignore Post-Dive Symptoms

After scuba diving, it's crucial to pay attention to your body's signals. If you experience symptoms like dizziness, joint pain, fatigue, confusion, or tingling in your limbs, it could be a sign of decompression sickness. Don't ignore these symptoms, and seek medical attention immediately. Early treatment can prevent more severe complications.


11. Don't Rush Your Dive Gear Maintenance

After a dive, it’s essential to properly clean and maintain your diving gear. Rushing this process or skipping it altogether can lead to equipment failure on future dives. Thoroughly rinse your gear with fresh water to remove salt, sand, and debris, and allow it to dry completely before storing. Regularly inspect your gear for wear and tear to ensure it's in optimal condition.
