After Diving: 10 Crucial Tips to Ensure a Safe and Enjoyable Experience


Immersing yourself in the fascinating underwater world is an experience filled with excitement and wonder. However, to ensure that each dive is as safe as it is rewarding, paying attention to both our actions underwater and our post-dive activities is essential. In this article, we will explore the ten things you should not do after diving. These guidelines will not only contribute to your safety but will also enhance your overall enjoyment of diving.

1. Do Not Fly Immediately After Diving: Time is Key for Safe Decompression

After delving into the ocean's depths, your body accumulates residual nitrogen. Flying too soon after diving can increase the risk of decompression sickness.

It is recommended to wait at least 12 to 24 hours before boarding a plane. This time allows nitrogen to safely released from your system, thereby reducing the chances of health complications.

Flying after diving stands as one of the most ingrained risks in the awareness of divers. This challenge is commonplace in the underwater realm, where the temptation to make the most of vacations and extend underwater time is constant.

The main reason to avoid flying immediately after diving is anchored in the aircraft cabin's pressure. The decreasing air pressure with altitude gain creates a situation similar to a rapid ascent during a dive. The more extensive and deeper the dives, the more nitrogen is absorbed into the blood and tissues. Upon returning to the surface, the reduction in ambient pressure transforms nitrogen into gas bubbles, a potentially dangerous situation within the body.

Decompression, crucial for allowing nitrogen to safely exit through the lungs, must occur gradually. Too rapid an ascent can promote bubble formation in the blood or tissues, leading to pain and, in extreme cases, fatal consequences. Waiting for the appropriate time before embarking on a flight helps to reduce nitrogen levels in the body. As a general rule, a surface interval of at least 24 hours before flying after any type of dive is advised, adding extra time as a precaution. This protocol covers all diving modalities, offering an extra layer of safety for the diver's peace of mind.

DAN's Guidelines for Flying After Diving

The following DAN guidelines apply to dives followed by flights at cabin altitudes of 2000 to 8000 feet (610 to 2438 meters) for divers not exhibiting symptoms of decompression sickness (DCS):

  • For a single no-decompression dive, wait at least 12 hours before flying.

  • For multiple dives per day or multiple days of diving, wait at least 18 hours before flying.

  • For dives requiring decompression stops, wait at least 24 hours before flying.

Additionally, you should wait longer if indicated by the dive computer's fly time. For added safety, many divers plan a surface interval of 24 hours before flying after any dive and use this time for rest or exploring surface attractions.

Now, here comes the additional touch of magic: if your dive computer suggests waiting longer, listen to it! Safety first, right? Some divers even take that extra time to recharge or explore what the surface has to offer. But don't close the page just yet, as there's more to discover about what you should avoid after diving.


2. Avoid Alcohol Consumption: Prioritize Hydration After Diving

Alcohol and diving do not make an ideal combination. After a dive, staying hydrated is crucial. Alcohol can increase the risk of dehydration and may adversely interact with residual nitrogen in your body. Opt for water or other non-alcoholic beverages to ensure proper recovery.

But if the temptation is strong and you decide to raise a toast, wait a few hours and do yourself a favor: hydrate well before lifting that glass!

3. Driving or Climbing Mountains

Adventure enthusiast, now let's talk about heights! Did you know that climbing or driving to the top of a mountain after diving can jeopardize your aquatic experience? Yes, it's surprising! But let me tell you why and how to avoid it.

Picture this: driving on a winding road up to a majestic 10,000-foot (3,048-meter) mountain. Well, that can be as risky for your health as flying in a plane after diving. The pressure in the cabin of a commercial plane is equivalent to being about 6,000-8,000 feet (1,800 to 2,400 meters) above sea level. If it already sounds like spell words, let me unravel it: altitude, whether in a plane or on land, can increase the risk of decompression sickness (DCS). Sure, some bold divers venture into what we call "altitude diving," but there are special tables for that.

Now, the spark of wisdom: avoid mountain climbing in the first 24 hours after diving. If you're a fan of combining diving and mountaineering on one trip (bravo!), here's the key: prioritize mountaineering before diving. This minimizes any potential risk of DCS. But be mindful of your physical well-being, resting and rehydrating after your mountain feat and before plunging into the next underwater challenge.

And if your return journey involves driving to altitudes after diving, don't forget to grant yourself a sufficient surface interval to reduce the risk of DCS, preferably 24 hours, or opt for an alternative route. The adventure continues in the heights and depths!

Rock climbing


Let's delve into the consideration of freediving after immersion, a practice that demands meticulous attention to ensure the safety of diving and apnea enthusiasts alike. The fusion of these aquatic disciplines can entail specific risks related to decompression sickness (DCS), highlighting two fundamental aspects, as per information provided by the Divers Alert Network (DAN):

  • Subaquatic Physical Exertion: Intensive apnea diving imposes a considerable physical demand, increasing the propensity for bubble formation in the body.

  • Bubble Contraction Under Pressure: Pre-existing bubbles in the body generated during diving can undergo a contraction process under water pressure, potentially entering the arterial circulation.

Considering the intersection of both disciplines, it is suggested to follow guidelines comparable to those applied for post-diving periods, according to the following general recommendations:

  • After a single no-stop dive, a waiting period of 12 hours is advised before engaging in apnea diving.

  • For multiple consecutive dives or extended days of diving, this interval is recommended to be extended to 18 hours.

  • In the case of dives requiring decompression stops, a 24-hour break is urged.

The duration of these periods can be adjusted based on the decompression time indicated on the dive equipment.

As a standard precautionary measure, waiting for 24 hours before practicing apnea after any type of diving is advised. This additional interval is considered an extra safeguard to ensure the safety and well-being of those participating in both aquatic modalities. This thoughtful approach contributes to a safe and continuous enjoyment of underwater wonders.


5. Sports

Regarding post-diving physical activity, divers must avoid intense exercise involving significant use of muscles, joints, or rapid limb movements. This precaution is based on the premise that such physical activity could increase bubble formation in the body, thereby amplifying the risk of decompression sickness (DCS). Practices to refrain from immediately after diving include:

  • 1. Weight Training at the Gym

  • 2. Swimming or Running after a Dive

  • 3. Participation in Sports like Beach Volleyball or Soccer

  • 4. Vigorous Dancing

According to researchers' consensus and the guidelines of the Divers Alert Network (DAN), a waiting period of at least 4 to 6 hours before undertaking any intense physical activity after diving is recommended. Although a waiting period of 24 hours was suggested in the past, a more practical perspective has evolved. As is common in other activities mentioned in this list, an extended interval between the dive and exercise will help mitigate the risk associated with decompression sickness. This cautious approach aims to ensure the safety and ongoing well-being of divers.


6. Skipping the Surface Interval

The fascination generated by diving is undeniable. After emerging to the surface from immersing yourself in the intriguing underwater world, where marine life unfolds in its splendor with manta rays, sharks, or playful seals, the temptation to dive again for a second, third, or even fourth time can be irresistibly strong.

However, it is crucial to understand that the surface interval is a non-negotiable aspect. After each dive, a residual amount of nitrogen will persist in your body, and its reduction to safe levels takes time. The necessary wait will vary depending on the depth and duration of the just-completed dive, as well as expectations for the next dive. Ignoring this recovery period significantly increases the risk of decompression sickness.

Beyond being a necessary pause, the surface interval reveals itself as an ideal opportunity to explore the charms of land destinations, exchange tales and experiences with dive buddies, and allow for a well-deserved rest before embarking on the next underwater adventure. This prudent approach not only contributes to safety but also enriches the overall diving experience.

7. Hot Showers or Jacuzzis

As the body warms up and circulation improves, the possibility of bubble formation increases. The Divers Alert Network (DAN) explains that "since the solubility of gas is inversely related to temperature, tissues will retain less solution as they warm. Warming tissues with significant gas loads can promote bubble formation."

Plunging into a hot shower or Jacuzzi immediately after a dive, especially if it is in colder waters, can lead to a rapid warming of tissues before blood flow increases. In this scenario, bubbles could form more quickly than circulation can remove them without causing harm, increasing the risk of decompression sickness.

To reduce this risk, it is recommended to:

  • Wait for 30 minutes before taking a hot shower or using a Jacuzzi, allowing the body to gradually warm up.

  • Adjust the temperature of the shower or Jacuzzi to avoid a too-rapid increase in body heat.


8. Massage

Wait! No massages? Relax and breathe! Here's good news from the Divers Alert Network (DAN): "Massage has not been securely associated with... cases of DCS." Experts advise against deep tissue massages, but a gentle relaxation massage is likely safe. The two main concerns regarding deep tissue massage are:

Increased blood flow could lead to bubble formation.

The advice is to stay away from deep tissue massages for at least 12 hours after diving. So relax, but maybe skip a deep massage for a while!

Muscle pain could result in a misdiagnosis (or delayed diagnosis) of decompression sickness (DCS).


9. High-Altitude Activities

Other high-altitude activities that should be avoided for more than 24 hours after diving include:

  • Skydiving or Parachuting

  • Paragliding

  • Parasailing

  • Skiing or Snowboarding

  • Hot Air Ballooning

We always recommend reaching out to someone with detailed information about the destination and its altitude. The best option is to contact a local PADI Dive Shop and inquire about other activities that can be safely done after diving, such as enjoying local cuisine, relaxing, or participating in local events. Stay safe and enjoy your diving experience!

10. Ignore Your Body

After a dive, it is crucial to pay attention to how you feel and respond accordingly. Certain signs and symptoms may indicate serious health issues that should not be ignored. For example, the onset of a rash, numbness, difficulty breathing, or dizziness after diving could be a sign of decompression sickness (DCS). Ear pain after diving could also indicate middle ear barotrauma or an infection.

Some signs and symptoms of decompression sickness can also be confused with other conditions. For example:

  • A red rash may resemble a sunburn.

  • A headache after diving may be mistaken for dehydration.

  • Nausea may result from seasickness.

  • Fatigue may be confused with simply feeling tired after a long day.

While there may be nothing to worry about and you may just need to rest and rehydrate, never ignore what your body is telling you.

If something doesn't feel right, talk to your dive buddy or dive guide and consider seeking advice from a medical professional. Your safety and well-being are of utmost importance.



After diving, the list of things you should not do may seem extensive, but there is also a wide range of activities you can enjoy. Here are some suggestions:

  1. Explore the region: Get to know the area, interact with locals, and immerse yourself in the local culture, always avoiding high-altitude activities.

  2. Check and clean your diving equipment: Keep your gear in optimal condition for future dives.

  3. Immerse yourself in entertainment: Enjoy movies, books, or virtual adventures with an ocean theme.
