Do not eat, do not drink after how long we die?

How long can we live without food and water? Have you ever wondered, tried it yourself or found it in books?

People say, people can fast for 3 weeks and fast for 3 days and still live. But really, that ability is very rare. Test yourself, one day you don't eat breakfast, only until 11:00 am you feel hungry, limbs are limp, tired and hungry. Of course, the time of suffering varies from person to person and depends on many factors. In particular, the willpower factor plays a key role. The will to help people perform a lot of miracles in history. So, sitting at home with a refrigerator full of food is definitely not a good environment for this test. This article will help you better understand the ability of humans to survive food or water shortages.

1. Lack of food

Will and determination play an important role in human fasting. Those who suffer from hunger for the longest are hunger politicians or ritual fasters of some religions, those who are lost in nature survived long periods of fasting.

According to the study, people can live up to 8 weeks just need to drink water without eating, however, there are people who exceed the 8-week mark, some have just died a few days later. This depends on your health status. Healthy people, fat people have better tolerance, so their ability to survive is higher. When we are hungry, we use our stored energy to survive. The process of using stored energy begins with burning carbohydrates, accumulated in the liver and muscle, followed by fat and eventually proteins in the body. If you are so hungry that you need to use protein, then your health condition is definitely very bad.

The body's metabolic capacity also contributes to its tolerance to hunger . If the metabolism is good, the body can absorb nutrients better. However, if you fall into a situation where there is nothing to eat, you will expect the opposite. Metabolic ability also determines the speed of using energy accumulated in the body. Therefore, the slower the metabolism, the slower the energy consumption, which will help you to survive a little higher. When hungry, the body's metabolic mechanism will automatically slow down, this is one of the natural survival instincts of humans.

Ambient temperatures also affect your ability to survive . If the environment is too hot, our body will lose water faster, when it is too cold, we will have to consume more energy of the body and therefore, the ability to survive is lower. However, often when the weather is too hot or too cold, there are many other factors that cause us to collapse before starvation.

At the beginning of hunger, the signs that your body feels are: fatigue, panic, tremor, frustration . After these initial reactions, the senses begin to stall, then start hallucinations, intestinal spasms, spasms of muscles, and abnormal heart rhythms.

One of the famous fasting cases is Indian leader Mohandas K. Gandhi. He fasted for 21 days. However, this is not the fasting record of politicians. In 1981, members of the Irish Republican Army when imprisoned in England held a hunger strike to protest, they only drank some water every day, not touching food. The then Deputy Prime Minister, Margaret Thatcher, was determined not to give in to these political prisoners. As a result, 10 people went on a hunger strike until death, among them, Kieran Doherty was the longest-time hunger striker, and he fasted 73 days before he died.

2. Lack of drinking water

People can survive for a long time without food, but without drinking water, you will be knocked out quickly. Children, if left alone in outdoor cars or heavy workers in hot weather, can die within hours without water.

People use water in their bodies in a lot of things like keeping their mouth and eyes moist, bringing nutrients and oxygen around their bodies . And we also have many mechanisms to dehydrate like urine - urination, Sweating, crying and even breathing make our bodies dehydrated. Under high-temperature weather, we can lose up to 1.5 liters of water through the sweat glands. Dehydration in hot weather can cause heat shock, which can be life-threatening.

When you have mild dehydration, you will reduce the secretion of saliva and also reduce the amount of urine you emit as well as urine that is now in a strange color, an unpleasant odor due to concentration. When you lose water more severely, your mouth will become dry, more difficult to urinate, your eyes will dry and sunken and your heart rate will beat abnormally fast. When you have severe dehydration, you can no longer urinate (anuria), hallucinations, irritability, vomiting and diarrhea. The final stage of dehydration is shock volume loss of circulation, pale skin.

Ordinary people can only survive 3 to 5 days without drinking water, just like when there is no food, healthier people can survive longer. The longest-lived case of water without drinking was Mitsutaka Uchikoshi of Japan when he had an accident at Mount Rokko in October 2006. Uchikoshi slipped his head and lost consciousness for 24 days before being able to Rescue team found. When discovered, his body was only 22 ^° C, his heart rate was weak and his organs stopped working. Uchikoshi doctors later found no damage in his brain, according to doctors, this is a rare case where humans appear hibernating . This helped Mitsutaka Uchikoshi escape from death.

Sometimes people want to fast to lose weight or to religions, fasting is also to cleanse the body, making people cleaner. But you absolutely never get tested for thirst, because this can cause serious damage to the body. According to the study, one day you should drink 2 to 3 liters of water.
