Hyperventilation does not give you more oxygen, it only get rid of the co2 in your body so your body thinks it has more oxygen and it wont feel so hard to hold your breath. This is NOT what you want, you want your body to start saving oxygen as soon as possible, called something in the line of diving reflex. What people have started doing, is slowly breathing in and out, breathing less and less before a dive, then take a big breath. This way, your body has alot of co2, but plenty of oxygen. It starts saving your oxygen. It will be more painful to hold your breath, but man, that is something you need to live with if you want to hold your breath and go free diving. Only after you are already 100% oxygen saturated. Before that point hyperventilation certainly increases oxygen levels. The lowering of CO2 levels is also desirable to a certain degree, CO2 being the "exhaust" and O2 the "fuel"....too much CO2 will cause problems holding your breath just as too much or too little oxygen will. | ||

Normally, your partial pressure of CO2 in arterial blood is between 35-45mmHg. If you have an increase in your CO2, you can appreciate that there will be a right shift in the Henderson Hasselbach equation which will lead to generation of protons in the plasma. This will hence drive chemoreceptor activity and increase respiratory rate. Why do you want to increase respiratory rate? Because your body need to tightly regulate pH by exhaling CO2, you will shift the equation to the right and take up protons. Why is regulating pH important? Because shifts in pH will lead to shifts in activity of enzymes in the body and may cause denaturing. If enzymes do not function optimally, then metabolism is compromised. By hyperventilating, you are effectively decreasing your pCO2 in the plasma and hence increasing pH in your CSF. This is called a respiratory alkalosis. This will favour your chemoreceptors to reduce rate of respiration to conserve CO2 and hence restore balance of the pH. This mechanism is only temporarily effective in reducing rate of respiration, as metabolism is always occurring in the body and CO2 will eventually rise to normal and then to higher limits. Another mechanism of respiratory drive is hypoxia which initiates respiration when peripheral O2 saturation falls below 80%. I do not recommend anyone try this technique so they can hold their breath longer. It can cause extreme hypoxic states where you lose consciousness. This is especially important for those that are in water and/or have underlying respiratory/cardiovascular compromise as they may place themselves in situation where they can be difficult to resuscitate. | ||

When one of my friends did it, some of the kids "helping" kicked him in the gut after he fell over, so when it was my turn I refused. I thought it was peculiar to the military base I was on, though. ...The dumb shit boys do to prove they're tough... amiright? . We did this too as kids... that's weird, now it seems like everyone around the world was doing it. We were 3rd grade at most.,.. I have no idea who taught us the technique, but I remembered it freaked me out and I didn't wanna try it coz some people's reactions were scary.. | ||
