About 60% of the human body is composed of water (H2O), and 71% of the earth’s surface is covered with water. Staying hydrated is essential for health and well-being, but many people are not consuming enough fluids every day. Perhaps the ubiquitous nature of water means that drinking enough people every day is not the top of many’s priority list.
Your body uses water in all its cells, organs, and tissues to help regulate temperature and maintain other body functions. Because your body loses water due to breathing, sweating and digestion, it is important to hydrate by drinking liquids and eating watery foods.
The amount of water you need depends on a variety of factors, including the climate you live in, how active your body is, and whether you have a disease or have other health problems.
This substance accounts for the majority of body weight and is involved in many important functions, including:
- Rinse waste from your body
- Adjust body temperature
- Help your brain function
You can get most of the water from drinking drinks, but the food also contributes a small amount to your daily intake.
For normal operation, all cells and organs of the human body need water.
Here are some reasons why our bodies need water:

1. Lubricate joints
Cartilage found in joint and spinal discs contains about 80% water. Long-term dehydration can reduce the absorption capacity of the joints, which can lead to joint pain.
2. It forms saliva and mucus
Saliva helps us digest food and keep our mouth, nose and eyes moist. This prevents friction and damage. Drinking water can also keep your mouth clean. It consumes instead of sweet drinks and can also reduce tooth decay.
Water is a major component of saliva. Saliva also includes small amounts of electrolytes, mucus and enzymes. This is essential for breaking down solid foods and keeping your mouth healthy.
Your body will usually produce enough saliva and take in fluids regularly. However, your saliva production may decrease due to age or certain medications or treatments.
If your mouth is dryer than usual and increasing intake is not helpful, see a doctor.
3. It delivers oxygen throughout the body
Water provides useful nutrients and oxygen to your entire body. Achieving daily drinking water will improve your circulation and have a positive impact on your overall health. The blood is over 90%, and the blood brings oxygen to different parts of the human body.
4. It can improve skin health and beauty
As you dehydrate, the skin becomes more susceptible to skin diseases and premature wrinkles. An adequate intake will help keep the skin hydrated and may promote collagen production. However, water intake alone is not enough to reduce the effects of aging. This process also connects to your genes and overall sun protection.
5. It relieves 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 thinking and reasoning problems.

6. Adjust body temperature
Staying hydrated is essential for maintaining body temperature. Your body is lost through sweat during physical exercise and hot environments.
Your sweat keeps your body cool, but if you don’t replenish the lost water, your body temperature will rise. That’s because your body loses electrolytes and plasma when it’s dehydrated.
If you sweat more than usual, make sure to drink plenty of water to avoid dehydration.
7. The digestive system depends on it
Contrary to what some people think, experts confirm drinking water before, during and after meals will help your body break down food more easily. This will help you digest food more effectively and make the most of the meal.
Research shows through trusted sources that the body adapts to changes in the consistency of food and stomach content, whether solid or more liquid.
The intestines need water to work properly. Dehydration can cause digestive problems, constipation and excessive acidic stomach. This increases the risk of heartburn and stomach ulcers.
8. Help excrete waste by sweating, urinating and defecation
Your body uses water to sweat, urinate and defecate.
Sweat regulates body temperature when exercise or when the temperature is warm. You need water to replenish the liquid you lost from sweat.
You also need enough water in the system to have a healthy stool and avoid constipation.
Your kidneys are also important for filtering waste through urination. An adequate water intake can help your kidneys work more effectively and help prevent kidney stones.
9. Helps maintain blood pressure
Lack of water can cause blood to thicken and increase blood pressure.
10. The airway needs it
When dehydrated, the airway is restricted by the human body to minimize water loss. This can worsen asthma and allergies.

11. It enables minerals and nutrients to be used
In addition to helping food break down, water also helps dissolve vitamins, minerals and other nutrients in food. It then passes these vitamin ingredients to other parts of your body for use.
These dissolve in water, which makes it possible for them to reach different parts of the body.
12. Prevent kidney damage
The kidney regulates fluid in the body. Insufficient water can cause kidney stones and other problems.
13. It improves performance during exercise
Some scientists suggest that consuming more water may improve performance during intense activity.
More studies are needed to confirm this, but one review found that dehydration can reduce the performance of activity that lasts for more than 30 minutes.
14. lose weight
If the water is consumed, rather than sweet juice and soda, it may also help with weight loss. Using water to “preload” water before meals can help prevent overeating, creating a sense of fullness.
15. It reduces the chances of hangover
Alternating unsweetened soda with ice and lemon to alcoholic beverages during parties can help prevent excessive consumption of alcohol.

16. It helps maximize physical performance
Drinking plenty of water during physical exercise is crucial. During physical exercise, athletes may lean up to 6% to 10% of their weight.
Hydration can also affect your strength, strength, and endurance.
If you participate in endurance training or high-intensity exercises like basketball, you may be more susceptible to dehydration.
The negative effects of calorie exercise without sufficient water may include severe medical conditions such as lower blood pressure and thermal therapy. Extreme dehydration can lead to seizures and even death.
17. It helps prevent constipation
Eating fiber is not the only way to prevent constipation. It is also important to maintain water intake so that there is enough water in your bowel movement.
If you don’t consume enough water, magnesium, and fiber, you may be more likely to experience constipation.
If you are already constipated, you may find that drinking carbohydrated water along with pure water can help relieve symptoms.
18. It helps fight disease
Drinking enough water can help prevent certain medical conditions. These include:
- constipate
- Kidney stones
- Asthma caused by exercise
- Urinary tract infection
- hypertension
Water can also help you absorb important vitamins, minerals and nutrients from your food, which will increase your chances of staying healthy.
19. This helps boost energy
Drinking water may activate your metabolism. Improved metabolism is associated with the positive impact of energy levels.
One study found that drinking 500 ml of water increased the metabolic rate in men and women by 30%. These effects seem to last for more than an hour.
20. It helps with cognitive function
Proper hydration is key to maintaining the cognitive shape of the tip. Research shows that not drinking enough water can negatively affect your attention, alertness, and short-term memory.
twenty one. Prevent overall dehydration
Dehydration is the result of your body not having enough water. And because water is crucial to many body functions, dehydration can be very dangerous.
Severe dehydration can lead to many serious complications, including:
- Brain swelling
- Kidney failure
- Epilepsy seizures
Make sure you drink enough water to make up for the loss of sweating, urination and bowel movements to avoid dehydration.
