Table of Contents

Whether it be a human, tree, animal, bird, or any organism, every living thing residing on this planet needs water for its survival and existence. Water is indeed an integral part that controls the life cycle of every individual and plays a significant role in their survival.

A human body is composed of 60-70% water, and an average human being needs about 2-3 liters of water consumption daily for better working of the body. People carry 2-3 bottles of water to work, while some even have apps installed on their smartphones reminding them to drink water at regular intervals. But why do people need water, and why is it so essential for the human body? Let us know more about it. (Cannas, D., Loi, E., Serra, M., Firinu, D., Valera, P. and Zavattari, P., 2020)

Role of Water in The Human Body:

The role of water in our life is not only to quench thirst but also to contribute to other body functions. It is a universally known thought that the human body is made up of 70% water. Still, there is a need to drink water because water gets used in many processes inside the human body to ensure the proper functioning of body systems.

Following Are Some of the Roles Where Water Plays A Major Role:

1. Regulating and Maintaining Cells and Tissues

The human body is constantly working to keep itself in a better form. The human body is made up of multiple cells and tissues that contribute to many life processes. These cells and tissues function continuously and need proper maintenance.

Here the role of water comes into the picture. Water helps in creating new cells and maintaining a proper balance of cells and tissues. It also helps to eliminate old cells which are no longer used in the body. It also helps in providing nutrients and oxygen to the cells for better functioning.

2. Maintaining a Proper Balance of Hydration Levels in The Body

As the water gets used up in various body functioning activities, the water level starts decreasing in the human body.  This may disturb normal functioning and can cause various problems.

Thus, in order to maintain a proper balance of water level in the body, one needs to follow a proper routine of water consumption to prevent dehydration. Being hydrated is very important as it regulates proper flow of blood. 

3. Flushing Out Toxins

Many processes are being carried out by the human body, which involves water as a partner. Water helps the digestive system ensure the smooth flow of food through the route while helping the kidney absorb useful nutrients. During processes such as digestion and urination, many toxins and waste materials are generated in the body, which needs to be eliminated from the body. 

Thus, water helps flush the toxins and waste after absorbing the necessary nutrients and chemicals required by the body. It prevents the body from being affected by the waste materials if it stays in the body for a long time.

4. Better Blood Circulation

Drinking 8-10 glasses of water helps the body prevent the danger of Hypertension and blood pressure. During high blood pressure, the walls of vessels turn narrow while blood becomes thicker due to a decrease in water level. This may cause several heart diseases and can be fatal.

Water helps maintain proper and smooth blood circulation without any obstruction and reduces the risk of heart-related issues.

5. Best Skin Moisturizer

People are cautious about their appearance and want their face, skin, body to be always healthy. People tend to buy various products and creams to tackle skin problems such as skin dryness, acne, and pimples for better skin. But a simple habit of drinking water regularly can help people solve their problems.

Water acts as a moisturizer helps make the tissues moist, and helps get better and healthy skin.

6. Better Muscles and Joints

Every person works so hard every day, which affects their body. People face problems in joints and muscle pain due to innumerable reasons, which cause trouble for them to even step out of their chairs and go for a walk.

Water helps and acts as lubrication in joints which ensures better movement of joints. It also helps for better bone health and provides blood circulation to every muscle, and eliminates the risk of muscle ache or strain.

Water Can Be Dangerous Too If:

Drinking a suitable amount of water regularly is beneficial to the human body in all aspects, and the results can be seen over time. But sometimes, in the flow of following the habit, people take up the practice so that they tend to drink water more than the requirement. (Joergensen, D., Tazmini, K. and Jacobsen, D., 2019)

Following Are the Problems Which Can Be Faced Due To Over Drinking Of Water:

1. Muscle Weakness

Excessive drinking of water can lead to muscle weakness. It can put extra pressure on the cells present in the body and make people feel weak and lethargic.

2. Kidney Disorders

Water is essential for the correct functioning of kidneys. But excessive water can damage and affect the functioning of the kidneys. It can lead to the formation of kidney stones and chronic kidney diseases.

3. Disturbing Brain Activities

Excessive water consumption leads to Cerebral enema in which there is the build-up of fluid in the brain. It affects the central nervous system by affecting the nerve stem in the brain. It can lead to severe problems such as coma, brain damage, and seizures.
