This article will address the risks associated with freediving. For example, there are several variables that can identify risks associated with freediving; with your body, the atmosphere in which you dive, etc. Here, by keeping all the risks associated with them in mind, we will assist you to evaluate and build a drive plan.
• Dangers associated with your body
1. Freedivers tend to get dehydrated in wetsuits, breathing through their mouths. The exhalation from the mouth tends to make one’s body lose water vapor and dehydrates it underwater. Dehydration gives a diver bad breath and headaches. An increase in dehydration negatively affects the performance of a diver.
2. Just before you go for a dive, stop eating foods that raise your heart rate. Divers should always keep their blood sugar levels in check. At least 2 hours prior to diving, one should have their last meal. A small snack, however, can also be eaten before diving. If you dive while you are hungry, the chances of a hypoxic episode will increase. Caffeine should be avoided at any cost as it tends to increase your heart rate.
3. Using recreational drugs can come in the way of cognitive functions by either making a person dull or overly excited. They should be avoided by a diver and their diving partner as it can hamper their coordination and cause uncalled-for accidents.
4. Overtraining one’s muscles as a freediver can be counterproductive as freediving requires more relaxation for going deeper in the water. Exercising beforehand, outside of water can give rise to loss of energy and cause fatigue.
5. Divers who have been prescribed any kind of medication must consult their physician before freediving. It is understood that certain drugs were a cause why the diver fell unconscious even at shallow depths.
• Dangers associated with the environment
1.Your body loses heat 25 times more rapidly under the surface of the water, so while diving during cold weather, it is necessary to wear a sturdy wetsuit to stop progressive hyperthermia.
2. Sunbeams reflected from the surface of the water can get very intense and cause severe sunburns. Wearing a waterproof sunblock with an SPF 50 or higher is advisable to avoid this.
3. A diver must always carry a sharp knife or cutter along with them while diving, just in case they encounter an entanglement with a fishing net or any other fishing equipment, they can easily cut through it.
4. Be attentive while having an encounter with fire corals, jellyfish, or any other plants and aquatic animals that can possibly harm you during your diving session. Research the region in which you go for freediving and make a list of what not to do and what to do if you get affected.
A diver should give time to danger assessment before going for a free dive. They should be well prepared in advance and carry a first aid kit with them. Check for emergency oxygen, a first aid box, and a phone with working service when going to a diving school or taking a diving course.
