For a healthy body, overbreathing or inhaling pure oxygen would have no benefit, no effect on oxygen delivery to our tissues and organs, and could actually create a state of oxygen deficiency, leading to relative suffocation. In other words, the pure oxygen a quarterback might huff between plays, or that a jet-lagged traveler might shell out 50 dollars for at an airport “oxygen bar,” are
of no benefit. Inhaling the gas might increase blood oxygen levels one or two percent, but that oxygen will never make it into our hungry cells. We’ll simply breathe it back out.

The kidneys, for instance, will respond to overbreathing by “buffering,”
a process in which an alkaline compound called bicarbonate is released into the urine. With less bicarbonate in the blood, the pH lowers back to normal, even if we continue to huff and puff. It’s as if nothing ever happened.

The problem with buffering is that it’s meant as a temporary fix, not a permanent solution.
Weeks, months, or years of overbreathing, and this constant kidney (renal) buffering will deplete the body of essential minerals. This occurs because as bicarbonate leaves the body, it takes magnesium, phosphorus, potassium, and more with it. Without healthy stores
of these minerals, nothing works right: nerves malfunction, smooth muscles spasm, and cells can’t efficiently create energy. Breathing
becomes even more difficult. This is one reason why asthmatics and other people with chronic respiratory problems are prescribed supplements like magnesium to
stave off further attacks.

They discovered that the optimum amount of air we should take in at rest per minute is 5.5 liters. The optimum breathing rate is about 5.5 breaths per minute. That’s 5.5-second inhales and 5.5-second exhales. This is the perfect breath.
