What does Freediving do to the body?

One of the most common questions I get is, “Bassel, what does freediving do to the body?”

If you have the same question, keep reading.

Freediving, also known as breath-hold diving, is a form of diving in which the diver holds their breath and does not use a breathing apparatus, such as scuba gear. 

During a freedive, the diver’s body undergoes several physiological changes as a result of the lack of oxygen.

One of the most significant changes that occurs during freediving is a decrease in heart rate. 

As the diver descends, the pressure of the surrounding water increases, which can cause the blood vessels in the body to constrict. This constriction reduces the flow of blood to the heart and can lead to a decrease in heart rate. 

The reduction in heart rate is a natural response that helps to conserve oxygen and extend the amount of time the diver can stay underwater.

The constriction of blood vessels can also lead to a decrease in blood flow to the brain and other organs, causing dizziness, nausea, and other symptoms.

Freediving can also have an effect on the respiratory system.

As the diver descends, the increased pressure of the water can cause the alveoli (tiny air sacs in the lungs) to collapse, making it difficult for the diver to exhale fully. 

This can cause a build-up of carbon dioxide in the body, resulting in hyperventilation (breathing too quickly) and an increased risk of blackout.

Freediving can have a significant impact on the body and it is important for divers to be trained before attempting a freedive.

At Apnea Zone, we tailor our training to your speed, strength and skill level, which helps you grow in confidence and make consistent progress.

Our trainers push you out of your comfort zone and help you get better every single day, without focusing on the outcome and without compromising on safety.

All our instructors are PADI certified and have an average training experience of over 10 years. 

We’ve trained people of all skill levels (beginner, advanced and master, across several nationalities, and have even trained other instructors). 

We have EFR services onsite. And oxygen tank providers as well – just in case someone blacks out. It’s never happened to us before but we want to make sure we are able to administer care until we get the person safely to hospital.

To make you feel at ease in the open water, we use the buddy system. Someone always always dives with you (one up , one down) so you never feel alone.
