Freediving Safety Guide


Freedivers pride themselves on their ability to dive down deep into the ocean with only one breathe. In fact, some of the world’s freediving records can be astounding. However, as is with any other type of water sport, there are some serious risks involved and divers should take the necessary precautions to ensure freediving safety.

One of these is to ensure that you have all the 10 essential pieces of freediving.

Without proper technique or the right guidance, your body can experience dangerous physiological risks. This freediving safety guide takes you through some safety rules for diving to make sure that your freediving inexperience remains safe.

Let’s dive in, shall we?

Never free dive alone

Always make sure that you have a dive buddy with you who is fully conversant with rescue techniques. He will be the guy who retrieves you in case something goes wrong.

Also, you should never dive together with your dive buddy and should only do so after he has come up to the surface. Simply put, you should always be under the supervision of your dive buddy when you make the dive.

One of the most important pieces of gear to have is a good freediving watch.


Always have a dive plan in place

Each diver that is on the dive line should know what the rest of the divers are doing and what they plan to do at all times. This will include doing the warm-ups and deep dives.

Before making the dive, analyze, and evaluate the dive area. Check the weather conditions, water visibility, currents, surface traffic, and the temperature of the water.

Always keep the freediving blood shift and spleen effect in mind when making the dive.


During the dive, equalize often and do so early before the sharp pain in your ear even develops. However, take care not to force an equalization.

If you try to equalize and it fails, do not dive any deeper and instead abort the dive.

No hyperventilation

One of the most important safety rules for diving is understanding the dangers of hyperventilation when freediving is that you can easily blackout on the dive. Instead, perform proper breathing which includes deep, slow, and relaxed ventilation.  Avoid overdoing your breathing.

Maintain the right interval between dives

When your dive buddy comes out from the water, make sure you focus your attention on him for no less than 30 seconds. And this goes even while he is showing okay signs. Sometimes problems will resurface later even while everything initially seems okay.

After you make the dive, make sure that you rest twice as long as you spend underwater.  Before making a second-deep dive, take at least 5 minutes to reoxygenate and to rest. This allows your body’s gas balance to go back to normal.

When you free dive your gear plays a huge role in ensuring your safety. A good freediving mask is essential.

Do not dive after a blackout

If you have experienced a blackout after a dive, never try to dive the same day as the risks of the blackout happening again are extremely high.

Instead, give your body time to recover and recuperate and try again the next day. In fact, if there is any type of loss of motor control, that should be the end of your diving for the day to ensure freediving safety.

 Always ensure that you are using only the best freediving fins when making the dive.

Never dive with a cold or when you are tired


Your body should be at its optimum when making a dive. If you have a cold, had a glass of alcohol, are feeling tired, or have a fever, these all impair your judgment. They will also heighten the risk of you experiencing a blackout.

Make sure that you have taken plenty of water and that you are fully hydrated. Dehydration increases the odds of experiencing blackout and also makes equalization much harder. You should also avoid diving when you are feeling congested as it makes it harder to equalize.

Also, while it’s important to not dive when you are hungry, you should avoid diving when you are too full. This is because most of the blood that would be carrying oxygen to your brain will be directed to the digestive system which could cause you to blackout.

Never combine scuba and freediving

This means that you should never share air with scuba divers, and you should also never free dive after you have done scuba diving. Instead, wait until the next day to make your free dive and to ensure freediving safety.

Listen to your body when freediving

Practice and learn how to be in control of your body at all times. Listening to what your body is telling you is important. Your body will tell you when it’s time to abort the dive. If you plan on freediving at the Canary Island, check out the 10 best freediving sites at the Canary Islands.
