Because you need oxygen to survive, and if you don't get the air, that carries oxygen, you will die. But you can practice holding it for longer periods of time, but if you hold it for to long, you may feel faint, so I suggest not to do that.

∙ 13y agoThe primary stimulus in the regulation of breathing patterns are the chemical changes in the blood such as the partial pressures of oxygen and carbon dioxide (PO2/PCO2) and hydrogen ion concentration (pH). Hydrogen ion concentration in the cerebrospinal fluid (CSF) has the earliest and greatest influence on respiratory activity. Hence, hypoventilation (as in breath holding) stimulates neurons of the inspiratory center in the medulla when the rising partial pressure of carbon dioxide decreases cerebrospinal fluid pH. Conversely, voluntary hyperventilation depresses the respiratory center via the decrease in partial pressure of carbon dioxide which raises cerebrospinal fluid pH.
Interestingly, exercize does not INITIALLY (in the beginning) affect arterial partial pressure of oxygen, partial pressure of carbon dioxide, or pH. It does stimulate the inspiratory center IMMEDIATELY and directly via action potentials from the cerebral cortex and mechanoreceptors located in joints. This is for a short time. Then the aforementioned scenario occurs.

∙ 13y agoBecause you need air.
Why do you need air? Because air turns in to energy when you breath it. so if your body has no energy u might dye. like what happens if you put water in a computer? Well it breaks right? that what happens if we hold our breath.

Will you live longer if you hold your breath if your throat is cut?
it depends, if the carotid artery and/or jugular are cut then you cant do anything about it, your virtually dead. if your windpipe, esophagus is cut then it depends, you want to keep as much blood out of the lungs as possible but if your throat is cut you might not want to live for very long... It mainly depends on the circumstances. if your close to the hospital then try not to breath as much. but holding your breath will also harm you... basically if your throat is slit then you are SOL man.

take in the biggest breath you can, and then add a quick forcable one so that you push your limits. Close your mouth and nose, then focus on some random and fascinating object.

How long can a 12yr old girl hold her breath?
There's two ways to find this information out. First way is to ask a 12 year old girl to hold her breath and see how long she can hold it for. The other method is to kidnap a 12 year old girl, then tell her to hold her breath. I don't recommend the second one but if you really have to, don't... Really... Don't do it.

Holding one's breath is a deliberate conscious act, thus it requires will). If breath can be witheld long enough, you will pass out and breathing will recommence. Breathing does not require willpower. It is automatic and orchestrated by the primitive brain stem. No consciousness is needed in order to breath.
