What happens if you dont exhale

If you watched illusionist David Blaine sail via balloons into the lofty heights of commercial air space in early September, you might recall that he once held his breath for more than 17 minutes. Does that seem safe in any way? Or even possible? In general, what happens to our bodies when we try to hold our breath? That depends on our own bodies and, obviously, the length of time we try to do it.

When we hold our breath for short durations, our bodies are equipped to make short-term compensations to keep all the organs working and all the functions continuing. In a simplified sense, our bodies are made of millions of microscopic cells that are like batteries with salt solutions separated by films, or barriers.

The movement of these salts across the barriers generates charge. That energy is the essence of life that allows the cells to talk to each other and maintain all the bodily functions. When we hold out breath for long durations, oxygen levels decrease and carbon dioxide accumulates in the body. That changes the concentration of free hydrogen ions, which makes these cells more excitable, leading to abnormal functions.

Tips for Land Animals Distance runners and cyclists would never dream of holding their breath during a competition, yet our instincts are to clamp up and stop breathing when our faces are in the water.

Go for a hard run or bike ride, and pay attention to your breathing. Apply that same breathing pattern in the pool. It's a common thought that inhaling is the important phase in the act of breathing, and people try to control it. Many say, "take a breath" or "tank up" when singing. I find that this controlled inhale can actually place unhealthy pressure on the diaphragm, often tensing neck and chest muscles that do not need to be overly involved in breathing.

Because most people are busy taking an in-breath, they do not pay much attention to the exhale process.

Without exhaling completely, excess carbon dioxide -- a known stressor in your nervous system -- may remain in your lungs. The system detects that there is too much carbon dioxide and not enough oxygen.

Then, it does the only thing it knows how to do: ask for more oxygen, causing another inhale. Since the lungs are still partially filled with carbon dioxide, not as much oxygen can get in. A cycle is set in motion and you keep inhaling for more oxygen, but can't get enough because the lungs have not been properly emptied. This habit can lead to shallow breathing and holding your breath.

However, when you exhale completely, your body is designed to take a "reflex" inhale. By releasing your ribs and expelling all air in the lungs, you engage the spring-like action of your ribs to expand and create a partial vacuum, and the air comes in as a neurological reflex.

This is what I call an optimal breath. It's called getting the wind knocked out of you, but it turns out that it's not the air or the wind that's the problem. It's your diaphragm say: DY-eh-fram. The diaphragm is a dome-shaped muscle under your lungs.
