Breathing underwater takes training
Breathing is not as easy as some may think and mastering it can be tricky.
We can become better divers by training our breathing techniques.
check out the excerpt from the article:
New divers are often told to take deep breaths. As a result, they fill their lungs to the brink, trying to take in as much air as they possibly can. But this means they’re often just taking a big breath, not necessarily a deep one. When you take a very big breath, the large amount of air you’ve inhaled adds lots of buoyancy, making it difficult to stay level in the water. This often motivates new divers to add excessive weight to their systems, making them too heavy for optimal buoyancy. Instead, think back to the exercise in Part I where you alternated between breathing into your chest and into your stomach. A deep breath goes into your stomach — but it doesn’t have to be a big breath to do that. Try breathing with your stomach while inhaling a normal amount of air. The purpose is to direct the air into the bottom of your lungs, to replace as much air as possible. This will help keep your air consumption down, as well as helping with your buoyancy.
Breathe in, breathe out
Maintain a slow, steady rhythm while breathing in and out, and minimize the pause between inhalations and exhalations, like the exercise in Part I. Try to migrate your air intake seamlessly into your exhalation with minimal or no pause. Maintain a slow and controlled breathing pattern; the purpose here isn’t to hyperventilate, but to minimize the changes in air volume in your lungs, as well as give your body a steady supply of fresh oxygen while getting rid of expelled carbon dioxide.
