how long can a human survive from not drink for a long time?

Answer 1

Humans body is a very complicated thing and everybody thinks differently when you ask them, "How long do you think a person could live without water?". Some people will say weeks, and others will reply a few days or even hours. Nobody knows exactly what it is but they have some guesses.


As the many researches have found out that a human body is made anywhere from %50 to %70 water. Water plays a big role in your organism. If there is no water the organs will not work properly and dehydration will start.


The approximate amount of days that you could go without water in your organism is anywhere from eight to fourteen days. It all depends on the person. How fast the water and liquids are going out of the body. Sweat, urine, and tears go out of a humans body and it is very hard to predict how the water inside of you is being reduced and by how much.


It is very different from the food situation because in case of food, a human body is able to hold on as long as three months or even longer. It all depends on the person's shape and structure. If the person is heavy and weights a lot then it is most likely for them to survive for a while. But if the person is skinny and out of shape, that person will have less chance to surviving for as long the the fat person.


Water and drinking is a very important part of your body running and growing. If you reduce the amount of water that you get every day, you are going to see some results like dizziness and headache. It is very important to have enough water every day. That is why when you are sick, you need as many liquids as possible because the water will clean out your organism and help you fight the decease.
