How long people can survive without food and water depends on many factors other than determination and conviction also affected. Medically, most doctors agree that humans are able to survive without water and food for some time. How long?
Physically, humans can live without water thirsty aka hold up to a maximum 3-5 days. While for the human hunger to survive without food for up to 8 weeks with the record still consume water. But if the physical condition of these people well, it could make someone survive much longer.
The body stores energy in the form of fat, carbohydrates and protein. Usually the body will use carbohydrates reserves first, then protein and the last to use fat as energy intake.
In addition to the food reserves in the body, metabolism and also affect the climate. People with slow metabolism tend to have longer satiety, because the body will adapt to existing conditions. Whereas if it is in a cold climate, the body will burn energy faster so that makes people feel hungry sooner.
In certain cases, as quoted from HowStuffWorks, Monday (30/11/2009) where someone has a body condition that is not good then it is likely that person can only survive without food for 10 to 14 days. People who experience high levels of hunger are marked by hallucinations, convulsions, heart rate irregular and non-functioning of certain organs.
While living without water is different from living without food. If the air is very hot and no water, so dehydration can occur within one hour. Therefore, someone could have died within a matter of hours if you do not have water and in hot conditions. However, if the surrounding conditions are not too hot or cold, a person can survive without water 3 to 5 days.
Human beings desperately need water to survive, because every day people lose fluid through sweat, urine, feces and even when breathing to 1.5 liters per day. Water is essential for the internal organs of the body agarbisa work properly.
The main risk of people living without water and heat conditions are the body temperature will continue to increase and that person can experience ‘heat stroke’. But if the person is drinking water then the lower core temperature and can cool it down.
People who lose lots of fluid will be marked with dry mouth, sunken eyes, rapid heart beat, irritability, vomiting and diarrhea. The final stage of dehydration is the body into shock characterized by skin grayish blue and cold to the touch.
It turned out that more people can survive without food than without water, because a person can survive for several weeks if no food but if there was no water only lasted 5 days
