Apnea is free diving, being underwater without equipment to help us breathe. In order to achieve this, Apnea is based on the voluntary suspension of breathing inside the water while traveling long distances or descending to great depths. But as we are not fish, this is achieved through training.
The technique consists of having to learn to contract the diaphragm in a way that helps pump blood to the brain and thus reduce the heart rate. Technique and control that we will learn in the courses of Apnea under the supervision of our PADI instructor to go getting achievements in a safe way.
