“We should drink 2-3 liters of water a day”, and “Have a glass of water before going to bed.” Water this, water that, but Why?? Why is water given so much importance? Why is it so beneficial for us?  

Water is considered to be one of the most important human needs. Our body consists of 60% water; this itself is an indication of how significant it is. 

Why Is Water So Essential?

Trees, dogs, fish, what do these have in common? Water. Many businesses have ventured into the water business; why’s that? Because everyone needs water, no person can survive without water on this planet.

Our body revolves around the importance of water. Water is essential from the blood in our body to various parts of the brain. Water also plays an important role in our immune system, which helps it fend off illness. Water is required to produce digestive juices, regulate body temperature, pee, poop, etc. 

Water protects various body parts like the spinal cord, brain, heart, lungs, etc. 

Drinking water doesn’t have a bad side, but excess water consumption can lead to complications. (Jéquier, E. and Constant, F., 2010)

How Much Is Water Too Much Water?

Overhydration can occur when water is drunk in excess. There is no specific limit for a person to meet his daily intake, but one should aim to drink at least 2 liters daily. For some people drinking 3 liters of water can also be excessive. (Barr, S.I. and Costili, D.L., 1989)

Let’s Have a Look At The Effects Excessive Consumption Can Cause:

  • Water poisoningThis upsets the electrolyte balance, causing symptoms like nausea and vomiting. Severe cases could lead to a coma or even death.
  • Disturbance in the brain’s functioningExcess water can cause the cells to swell up, resulting in the brain under pressure. This causes confusion, drowsiness, headaches, etc.
  • Muscle Weakness: Excess water can pressure the body's cells so that one can feel lethargic.

Water Against Toxins:

Water doesn’t solely flush out any toxins out of our body but aids in collaboration with other organs, digestive juices, blood, etc.

Toxins are naturally a relative when it comes to human anatomy. For example, when our body is in digestion, the toxins are disposed of by the bowels in the form of excretion.  (Zaccaroni, A. and Scaravelli, D., 2008)

Toxins Usually Compromise of:

  • Pollutants
  • Synthetic chemicals
  • Heavy metals
  • Processed foods

Now, all these toxins are filtered out of the body by our various organs. These organs are aided by water since the cells used to power these organs require water to function. 

A healthy amount of water can be one of the best natural detoxes a person can inculcate in his lifestyle. A sufficient quantity of water leads to a healthy lifestyle.

Symptoms of Toxins in Your Body:

The average human is exposed to more than 5, 00,000 chemicals daily. These toxins can be present in Air conditioners, Perfumes, Soaps, Plastic bottles, etc. You never know where you can expect them. 

Such exposure to chemicals can have disastrous effects on us. These effects may not be as vibrant in the short run but can have ill effects in the longer run. 

Here Are a Few Symptoms If You’re Exposed to Toxins:

What Toxins Can Lead to:

Toxins not only harm the body from the outside, but their effects also harm us internally. For example, our body produces digestive juices to act as a catalyst in the digestive process. Any foreign matter present in this could alter the process in a bad way that could cause ill effects like diarrhea, constipation, Irritable Bowel Syndrome, hemorrhoids, etc. 

The Following Are a Few Causes:

  • Parkinson’s disease 
  • Heart-related diseases
  • Change in behavior 
  • Various types of cancer
  • Swelling of limbs

How Much Water Should You Drink?

  • Gender
  • Physical activity
  • Climate
  • Any life conditions 

Water is an essential resource for our bodies. A few liters a day keeps the doctor away.
