What happens to the human body when staying for a long time without food or water ?!



A person can stay for a long time without food as long as he drinks water, but he cannot stay without drinking water. Of course, body weight and health play a big role in endurance, but the question here is how long can the body tolerate without food or drinking water? What happens to the body?


The answer to such a question is not easy and depends mainly on the person, the circumstance and the position in it.

Live without food

Most doctors agree that a healthy person can stay about eight weeks without food as long as he drinks water, and he can stay for longer than that. The more powerful and good a person’s physical condition is, the more helps him to survive for a longer period. Fat in the body must exist, because the body’s energy stores necessary to keep him alive are in the form of fats, carbohydrates and proteins.
The first thing that is used when there is no more food is carbohydrates, and then fats, and this explains why people who have more fat live longer without food, and after using fats comes the role of proteins and when this happens things get very bad.
Metabolism also plays a role, and it is metabolism that converts nutrients into energy. If you have a slow metabolism, you will burn the food more slowly and the body will be able to stay for longer periods without replacing the food energy.
So she is doing her best to keep the person alive, in other words if the body stays without food then metabolism will adjust itself accordingly and slow down on its own.
We can add the climate as it is a major factor that also plays a role. Of course, before starting and speaking, both cold and hot rituals are not good for those who do not eat food, and it is known that freezing cold and intense heat will kill a person before he has a chance to die of hunger.
For those who live without food in very hot or very cold weather, the heat means to the body more drier and the cold means burning more energy to maintain a suitable temperature for the body (98.6 degrees Fahrenheit -37 degrees Celsius).

Some symptoms that appear when you have been without food for more than two days

  • Confusion and confusion
  • Chronic diarrhea
  • Irritability

  • Decreased sexual drive
  • HIV
Staying without food for an advanced stage will cause your body organs to stop one by one, and the person will suffer from
  • Hallucinations

Live without water

After we talk about food and we say that a person can stay without it for a reasonable period of time, let's move on to water. As it is known, water is life, and living without it is very different from living without food. In very hot climatic conditions with no water, a person can become dehydrated within an hour. If this person is very tired of the heat and without replacing the fluids, he may die during Several hours.
Humans need water in order to live that it is clear and simple. We lose water through sweat, urine, and feces, and we even lose it while breathing, and we need water to replace what we lost in order for our members to continue to work properly.
Adults in high and intense heat lose about 1.5 liters of water through sweat only, and the main danger to life is to stay without water with very high heat as drinking water helps cool and lower the body temperature.

The person will experience moderate dehydration
  • Less salivation
  • Decreased urine frequency
  • Decreased urine production
  • Strong odor and dark color of urine
With a slight mild dryness will face
  • Dry mouth
  • Dry eyes
  • Speed ​​in the heartbeat
Severe dehydration
  • There is no urine
  • Lethargy and irritability
  • Vomiting and diarrhea
We first talked about severe drought and high heat, but let's go back to the question, more importantly, how long can humans live without water? Here we will speak in a reasonable climate and not in a very hot or very cold place. In these circumstances, people can live for 3 to 5 days without water.
And whoever has good health can live for another day or for a longer period than others, and of course it is always advised by doctors to drink about eight cups of water per day or more because water for humans is life.
