The importance of water on human body cannot be overemphasised. It serves as a lubricant to the digestive system and all other body processes.
To avoid dehydration drink at least eight glasses of water every day as an adult.
Here are reasons you should drink enough water daily:
- It delivers oxygen throughout the body: Blood is more than 90 percent water, and blood carries oxygen to different parts of the body.
- 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 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 helps maintain blood pressure: A lack of water can cause blood to become thicker, increasing blood pressure.
- 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.
- It prevents kidney damage: The kidneys regulate fluid in the body. Insufficient water can lead to kidney stones and other problems.
- It flushes body waste: Water is needed in the processes of sweating and removal of urine and faeces.
- Reduces weight loss: 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 boosts skin health and beauty: With dehydration, the skin can become more vulnerable to skin disorders and premature wrinkling.
- 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.
