Hunger isn’t the only thing that kills people; dehydration can also kill them since a hungry person is less sensitive to thirst. There is also a significant risk of getting a deadly infection due to the weakened immune system. Vitamin insufficiency can even be fatal. When a person goes without food for an extended period of time, the body begins to utilize muscle protein (including the heart) as a source of energy. Then cardiac arrest owing to tissue injury and electrolyte imbalance might be the cause of death.

Sleep is well-known to play a role. Sleep deprivation causes poor attention, slowed brain processes, reduced motivation, and altered perceptions of reality. Normal individuals cannot sleep for eight to ten hours without causing harm to their health, according to research.
Randy Gardner, a 17-year-old schoolboy who did not sleep for 264 hours (about 11 days) during a scientific experiment in 1965, holds the global record. There are, however, uncommon diseases such as Morvan’s syndrome, in which a person may go months without sleeping! The topic of how long individuals can sleep remains unsolved in the end.
How long can you go without breathing?
How long can a human survive without air, or more precisely, without oxygen? When the brain is deprived of oxygen, it dies as a result of a shortage of glucose to fuel brain cells. About six minutes after the heart stops pumping, the brain dies. The brain cells will not be badly harmed if aid arrives during this period. People, on the other hand, may learn to use oxygen more effectively. Without damaging his brain, the world-freediving record holder maintained his breath for 22 minutes and 22 seconds!
