The first question most beginners ask themselves before a discovery dive in Djerba is simple: how do you breathe underwater?
Breathing while scuba diving is very different from breathing on the surface, but it's much simpler than you might think. With proper guidance and a few basic techniques, everyone can get used to it quickly.
In this guide, you will discover how underwater breathing works, the essential techniques, and the tips for succeeding in your first dive in Djerba with complete peace of mind.
1. How does breathing work in scuba diving?
Underwater, you don't breathe water directly, but compressed air contained in a tank.
This system is made up of two essential elements:
- The diving tank : it contains compressed air
- The regulator : it transforms this air into breathable air at normal pressure
--> Thanks to the regulator, you can breathe normally as you would on the surface.
2. Is it natural to breathe underwater?
At first, the sensation may seem strange, but it quickly becomes natural.
Beginners often experience:
- Slower breathing
- A feeling of calm
- Greater awareness of their breath
--> After a few minutes, breathing becomes automatic.
3. Breathing technique in diving
3.1 Breathe slowly and deeply
The main rule is simple:
- Breathe in slowly
- Breathe out completely
- Keep a regular rhythm
--> Slow breathing allows you to consume less air and extend your dive.
3.2 Never hold your breath
This is an essential safety rule:
- Never hold your breath
- Always keep breathing continuously
--> This prevents pressure variations in the lungs.
3.3 Breathe in a relaxed manner
The key is relaxation:
