safety tips for freediving training
Discussions about freediving safety in competitions are always evolving, but what about safety during training?
We may not dive to the same depths as the top freediving athletes, but this does not exclude the possibility of a blackout or samba, which means applying all the necessary measures that make diving not only as pleasant as possible, but also safe. Safety should always be the number one task for every freediver, but, unfortunately, it is often not taken seriously enough, especially by novice divers.
Below are 7 important tips to help you avoid common mistakes and improve the safety of your workouts.
Deep Freediving Training
1. Never dive alone
The most important rule of freediving, which is constantly talked about at every freediving course, and no matter what your level of diving.
Choose an experienced partner. Ideally, your level or higher. A partner must know the principles of insurance, how to react in case of samba or blackout and how to provide first aid.
Remember and practice this important skill periodically during your workouts.
2. Never force a purge
Deep freediving training Do not test your eardrums for strength, they will still come in handy in life.
Remember to pre-purge the surface before diving. When immersed, purge constantly and regularly, without waiting for any discomfort or pain. Any pain is a microtrauma for the eardrum.
If it was not possible to immediately equalize the pressure, stop diving. The idea that the goal is close and there are only 2-3 meters left to the end of the cable and can be tolerated is deceptive and very dangerous. This can easily damage the eardrum.
It is especially offensive when you come for diving a week or two somewhere far away in the tropics and want to spend this time as efficiently and intensively as possible. One unsuccessful “booster” of the purge can jeopardize the entire subsequent freedive vacation.
3. Choose the right cargo
With a lot of cargo it’s easier to dive – it’s easier to dive, earlier free fall begins, etc. But do not forget that you will have to come up later. Congestion will lead to too much energy consumption during ascent and the inability to completely relax on the surface. In addition, diving too fast can cause pressure equalization problems.
The load must be selected so that you are neutral at a depth of between 10 and 15 meters. Always check your buoyancy when you haven’t dived for a long time, dive in new equipment (the thickness of the wetsuit affects buoyancy) or the new sea (buoyancy depends on the salinity of the water).
4. Hydration and nutrition for freedivers
Deep freediving training It is not recommended to dive within 3-4 hours after a full meal and 1-2 hours after a light snack. The digestion process requires an additional blood flow to the stomach, which reduces its rush to other vital organs and significantly reduces the duration of the breath hold.
Ventilation, prolonged exposure to water, and diuresis during freediving can lead to dehydration of the freediver. Dehydration makes it difficult to purge, reduces the ability of the blood to carry oxygen, reduces the possibility of holding your breath, and increases your risk of blackout. Therefore, during training, there should always be a supply of water in the buoy, and the more often you drink it, the better. Freedivers love water not only outside, but also inside themselves;)
5. Make a dive plan and always chat with your partner
Before training, make a diving plan with your partner, taking into account all the conditions of the upcoming diving (weather, waves, currents, visibility, etc.).
Each of the freedivers should know what the partner is going to do (the number of warm-up dives, dives to the maximum depth, etc.).
6. Never exhale under water and do not exhale too sharply on the surface after surfacing
When exhaling under water, you lose, firstly, precious oxygen, and secondly, reduce your buoyancy, which requires more effort to rise to the surface. In addition, exhaling at depth can result in lung barotrauma.
Always perform correct restorative breathing on the surface. Sudden exhalation and improper breathing on the surface can provoke a samba or blackout. Always remind your partner to breathe correctly after surfacing if you see that he forgets to do it. Proper breathing after diving should be your automatic reflex.

7. When diving deep, always use a bright buoy to mark the dive site and the cable
The buoy is not only a platform for rest and a place for fastening the cable, but also a surface marker that makes freedivers noticeable for boats. In places where there is boat traffic, boats are the number one enemy for the freediver.
