Freediving or apnea is the art of breath hold diving where a diver descends on a single breath of air, without any breathing apparatus.
So every time you hold your breath and swim underwater you are freediving!
Freediving is a mental and physical activity. It challenges the body and the mind. It is all about learning to fully relax, let go and embrace the present moment. Freediving helps to control the mind, get over anxiety and build confidence.
Anyone can learn to freedive with proper instruction, no matter the age or experience.
