Growing up, we were constantly told that you should drink at least 8 cups of water per day by grownups. When we are younger, we never really questioned them and just went along with anything they said. As we grew older, we begin to wonder why we should drink 8 cups of water every day? and no one could give us a satisfactory answer; all we received was "water is healthy."

It was never explained to me how it helped us. If you've had a similar experience, don't worry; today, we'll look at the importance of water in maintaining a healthy lifestyle and how much of it you need to drink. (Kumari, P. and Bhargava, B., 2021)

Water Helps In The Lubrication Of Joints.

Water is a part of synovial fluid that helps to prevent joint friction. Synovial fluid lubricates and cushions joints and the cartilage surrounding them, preventing bones from rubbing against each other.

Water Helps In The Regulation Of Body Temperature.

Water has a high specific heat capacity, which means it can absorb a lot of heat before rising temperature.

Every cell in the human body contains water, which acts as a temperature buffer. When the body needs to save heat, blood travels towards essential organs, and when the body is at risk of overheating, it moves toward the extremities. To cool the body, water evaporates from the skin and lungs. (Burdine, J.D. and McCluney, K.E., 2019)

Water Aids Digestion And Helps To Avoid Constipation.

One of the most common reasons for chronic constipation is dehydration. The food you eat travels from your stomach to your colon or big intestine. The large intestine absorbs water from your dietary waste if you don't have enough water in your body. This causes you to have firm, difficult-to-pass stools. Water and other liquids aid in the digestion of meals so that nutrients can be absorbed. Water also softens feces, which aids in constipation prevention.

Water Forms Saliva And Mucus.

Saliva aids in the digestion of meals and keep the lips, nose, and eyes moisturized. As a result, friction and damage are avoided. Water also aids in the cleaning of the mouth. When consumed instead of sugary beverages, it can also contribute to the prevention of tooth decay.

Water Can Help Avoid Kidney Damage.

Water aids in the elimination of wastes from the bloodstream through the kidneys in the form of urine. Water also helps to keep your blood vessels open, allowing blood to freely flow to your kidneys and deliver essential nutrients. This delivery method becomes more difficult to employ if you become dehydrated.

Mild dehydration might make you weary and limit your ability to perform basic bodily tasks. Dehydration can cause kidney damage, so it's crucial to drink enough water when you're working or exercising hard, especially in hot and humid conditions.

Water Can Help Improve Performance During Exercising.

With as little as 2% dehydration, almost every measurement of performance aerobic endurance, strength, power, speed, agility, and response time – diminishes. Staying hydrated boosts energy enhances movement, recovery, and agility improves thermoregulation and boosts mental clarity and activity - all of which can help you perform better and avoid injuries.

Water Improves The Health And Looks Of The Skin.

Water keeps your body hydrated and refreshed while also keeping your skin flexible. People who drink plenty of water have fewer scars, wrinkles, and soft lines, as well as fewer signs of aging than those who don't. (Smith, A.H., Lingas, E.O. and Rahman, M., 2000)
