In order to function properly, all the cells and organs of the body need water. Here are some reasons our body needs water:
It lubricates the joints
Cartilage, found in joints and the disks of the spine, contains around 80 percent water. Long-term dehydration can reduce the joints’ shock-absorbing ability, leading to joint pain.
It forms saliva and mucus
Saliva helps us digest our food and keeps the mouth, nose, and eyes moist. This prevents friction and damage. Drinking water also keeps the mouth clean. Consumed instead of sweetened beverages, it can also reduce tooth decay.
It delivers oxygen throughout the body
Blood is more than 90 percent water, and blood carries oxygen to different parts of the body.
It boosts skin health and beauty
With dehydration, the skin can become more vulnerable to skin disorders and premature wrinkling.
It cushions the brain, spinal cord, and other sensitive tissues
Dehydration can affect brain structure and function. It is also involved in the production of hormones and neurotransmitters. Prolonged dehydration can lead to problems with thinking and reasoning.
It regulates body temperature
Water that is stored in the middle layers of the skin comes to the skin’s surface as sweat when the body heats up. As it evaporates, it cools the body. In sport.
Having a lot of water in the body may reduce physical strain if heat stress occurs during exercise. However, more research is needed into these effects.
The digestive system depends on it
The bowel needs water to work properly. Dehydration can lead to digestive problems, constipation, and an overly acidic stomach. This increases the risk of heartburn and stomach ulcers.
It flushes body waste
Water is needed in the processes of sweating and removal of urine and feces.
It helps maintain blood pressure
A lack of water can cause blood to become thicker, increasing blood pressure.
The airways need it
When dehydrated, airways are restricted by the body in an effort to minimize water loss. This can make asthma and allergies worse.
It makes minerals and nutrients accessible
These dissolve in water, which makes it possible for them to reach different parts of the body.
It prevents kidney damage
The kidneys regulate fluid in the body. Insufficient water can lead to kidney stones and other problems.
It boosts performance during exercise
Consuming more water might enhance performance during strenuous activity.
More research is needed to confirm this, but one review found that dehydration reduces performance in activities lasting longer than 30 minutes.
Water may also help with weight loss, if it is consumed instead of sweetened juices and sodas. Preloading with water before meals can help prevent overeating by creating a sense of fullness.
It reduces the chance of a hangover
When partying, unsweetened soda water with ice and lemon alternated with alcoholic drinks can help prevent overconsumption of alcohol.
Water helps dissolve minerals and nutrients, making them more accessible to the body. It also helps remove waste products.
These two functions make water vital to the kidneys.
Every day, the kidneys filter around 120-150 quarts of fluid.
Of these, approximately 1-2 quarts are removed from the body in the form of urine, and the rest is recovered by the bloodstream.
Water is essential for the kidneys to function.
If the kidneys do not function properly, waste products and excess fluid can build up inside the body.
Untreated, chronic kidney disease can lead to kidney failure. The organs stop working, and either dialysis or kidney transplantation is required.
If infections spread to the upper urinary tract, including the kidneys, permanent damage can result. Sudden, or acute, kidney infections can be life-threatening, particularly if septicemia occurs.
Kidney stones interfere with how the kidneys work. When present, can complicate UTIs. These complicated UTIs tend to require longer periods of antibiotics to treat them, typically lasting 7 to 14 days.
The leading cause of kidney stones is a lack of water. People who report them often do not drink the recommended daily amount of water. Kidney stones may also increase the risk of chronic kidney disease.
Dehydration happens if we use and lose more water than the body takes in. It can lead to an imbalance in the body’s electrolytes. Electrolytes, such as potassium, phosphate, and sodium, help carry electrical signals between cells. The kidneys keep the levels of electrolytes in the body stable when they function properly.
When the kidneys are unable to maintain a balance in the levels of electrolytes, these electrical signals become mixed up. This can lead to seizures, involving involuntary muscle movements and loss of consciousness.
In severe cases, dehydration can lead to kidney failure, which can be life-threatening. Possible complications of chronic kidney failure include anemia, damage to the central nervous system, heart failure, and a compromised immune system.
Some of the water required by the body is obtained through foods with a high water content, such as soups, tomatoes, oranges, but most come through drinking water and other beverages.
During everyday functioning, water is lost by the body, and this needs to be replaced. We notice that we lose water through activities such as sweating and urination, but water is lost even when breathing.
Drinking water, whether from the tap or a bottle, is the best source of fluid for the body.
