The water in our bodies is essential for life. Without water, we cannot survive. The fact that water is lost continually or being used, it needs to be continually replaced, and the best fluid to replace it is water. The human body is made up of cells that are filled with water and needs water to perform their day-to day activities. Two-third of the human body is water. Your blood, which is responsible for carrying oxygen, nutrients, and waster products to and from cells, is more than 95% water. Water is even a major participant in many of the chemical reactions that take place in the body’s cells.

Water is the most often neglected nutrient. Yet, it is one we can live the least time without. A person can survive only a few days without a water source, because humans need about a quarter a day for cleaning out waste products. Waste products are created by metabolic body processes, such as breaking down food for use as energy. These waste products get into the bloodstream, where they are transported to the kidneys for filtering and removal through the urine. When water intake is lower than the amount needed for this waste management process, the kidneys work hard to concentrate the urine and re-absorb as much water as they can. The end result is that these waste products –some of these toxins – stay in the body longer than necessary. Here are additional benefits of water.

To keep hydrated: Keeping hydrated is crucial for health and well-being. Many people do not consume enough fluids each day and this predisposes to dehydration. When dehydrated, the skin can become more vulnerable to skin disorders and wrinkling. There is no universally agreed quantity of water that must be consumed daily but it is advisable to have at least 1.5 to 3 liters minimum daily.

To function well in day-to-day activities: To function properly, all the cells and organs of the body need water. Water is essential for the function of organs in the body such as the kidneys and other bodily functions.

It lubricates the Joints: Cartilage, found in joints and the disks of the spine, contain 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 helps the mouth clean. Consumed instead of sweetened beverages, It can also reduce tooth decay.

It boosts skin health and beauty: When dehydration occurs, the skin can become more vulnerable to skin disorders and premature wrinkling, causing dry skin and prone to damage.

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 helps regulate the body temperature: Water is an important player in regulating body temperature (especially cooling through sweat), people who live in warm climates or do physical activity (which creates heat internally) needs to drink more fluids than those who are inactive or living in cold places. 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. 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.

It greatly helps the digestive system: The bowel needs water to function properly. Dehydration can lead to digestive problems, constipation, and an overly acidic stomach. This increases the risk of heartburn and stomach ulcers.

It removes wastes from the body: Water is needed in the processes of sweating and removal of urine and faeces.

It regulates blood pressure: Lack of water can cause the blood to become thicker, increasing the blood pressure.

It boosts performance during exercise: It has been proposed that consuming more water might enhance performance during strenuous activity.

It helps weight loss: Water may also help with weight loss, if it is consumed instead of sweetened juices and soda. “Preloading” with water before meals can help prevent  overeating by creating a sense of fullness.
