How will your body change if you stop drinking?

Every creature that lives on Earth that we know the head needs water to survive. That's why we are always in need of water every day.

When it comes to water, it includes other solutions that contain water such as juice, soft drinks or tea. Similar to the need for oxygen to breathe, " thirsty " is the human instinct for survival. Water accounts for about 65% of the adult body's mass and it is a " general " solvent that carries nutrients and hormones to all internal organs, regulating body temperature, lubricating knee joints and even eyes.

The body lacks water, you will feel dry mouth, dizziness, slow reaction.

People emit about 1.5 liters of urine daily, and release 1 liter of remaining water through breath, sweat and feces; The body must then compensate for this water. Our brain will emit a " thirsty " signal when the brain's receptor measures the amount of water in the blood below the prescribed level. For example, when sweating, blood and blood pressure in the body will decrease, the brain then signals " Drink water now! ". However, what happens in the body if you do not meet the needs of the brain when not drinking water?

The first sign of dehydration is dry mouth , then the urine will darken and smell worse because the body has lost its ability to retain water. The brain will then be affected, you will feel dizzy, slow to respond and reduce your ability to feel pain. In fact, when the water is lacking, the brain becomes shrunken, if it is not supplied with water for 1-2 days, you will stop urinating, having trouble swallowing, the muscles are spasms and nausea. People who are dehydrated for a long time will develop brain failure , no longer feel like eating and blood will reduce the level of subcutaneous flow to prevent heat loss, but at the same time the body's internal temperature will increase. That's why people who lack water look very " pale ".

When not being supplied with water for 3-5 days, the body and brain will stop working and it will be difficult for us to survive this level. When you experience these " thirsty " signs, add water to your body as soon as possible.

Unlike the air we are breathing, only 2.5% of the water on Earth is drinking water. Most of this water is contained in ice and groundwater, leaving only 1% of human water available. Moreover, the remaining water is mainly used for irrigating plants in agriculture and cooling the thermal power plant system. In addition, many people around the world are using heavily polluted water.

Scientists are still looking for ways to solve the problem, for example NASA has found a way for astronauts to filter their own urine to drink. However, there is no thorough and effective way to filter large quantities of water. So in the present time, save water when possible.
