However, if a person is very sick, or in a vegetative state from a stroke or severe brain injury, that person can only survive approximately 10-14 days without food. How long can you live without water? The usual survival time without water is 3 days, but there have been occasional occurrences of people surviving 8-10 days without water. How long can you live without breathing? Usually a person can only survive 3 minutes without breathing, although there are women divers In Japan and other countries who dive for abalone or pearls who are able to survive for 5 minutes at a time, even diving to a depth of 100 feet, on a single breath, though this requires years of training.
Between 30-180 seconds of oxygen deprivation, you may lose consciousness. At the one-minute mark, brain cells begin dying. At three minutes, neurons suffer more extensive damage, and lasting brain damage becomes more likely. At five minutes, death becomes imminent. At 10 minutes, even if the brain remains alive, a coma and lasting brain damage are almost inevitable. At 15 minutes, survival becomes nearly impossible. There are, of course, exceptions to every rule. Some training routines help the body make more efficient use of oxygen, enabling the brain to go longer periods without this vital element. Free divers routinely train to go long periods without oxygen, and the current record holder held his breath for 22 minutes without sustaining brain damage!
