Why Drinking Water Is Important

Why Drinking Water Is Important

  • Why drinking water is important is due to the basic fact that water can improve cognitive functions, burn fat, ease dehydration, regulate body temperature and help with digestion among many things.

Water can help maintain brain function, regulate body temperature and flush out toxins and wastes from our bodies.

Why drinking water is important is due to the basic fact that without it there would be no life form on earth.

On this post we shall be listing the various reasons why drinking water is important to us all.

1. Encourages Weight Loss

It would interest you to know that drinking water to lose weight is a very valid weight loss tip.

Water increases our resting energy expenditure. Which is another way of saying that water actually increases the amount of calories that we burn.

In one study involving obese women, it was proved that absolute and relative increases in drinking water were associated with significant loss of body weight and fat over time, independent of covariates.

Suggesting that drinking water may promote weight loss in overweight dieting women. 1

2. Creation Of Saliva

Produced in salivary glands, saliva is 98% water, but it contains many important substances, including electrolytes, mucus, antibacterial compounds and various enzymes.

Which means that less water can easily translate to reduced saliva in your mouth.

Which is not good, due to the fact that saliva is responsible for moistening foods so that we can easily swallow.

Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin.

In other words saliva greatly aids the digestive functions of the body. Because obviously, the digestive process starts in the mouth. 2

3. Regulating Body Temperature

Another reason why drinking water is important is because most tissue is water, 60-70%.

Water makes up approximately 60% of our total body composition. In addition, 73% of lean body mass or muscle is composed of water.

The human body regulates temperature by keeping a tight balance between heat gain and heat loss.

Core temperature is regulated by the hypothalamus (in the brain), which is often called the body’s thermostat.

On a hot day, temperature receptors located in the skin send signals to the hypothalamus to cool the body by increasing the sweat rate.

Water is part of the thermoregulation process, because water is a major component of blood volume.

Water is mainly lost through sweat, respiration, and waste. However, when the body is dehydrated, most of the water lost is from the blood. 3

4. Keeps Constipation At Bay

Water can really help you in the fight against constipation because it is a condition that can be caused by dehydration.

Dehydration causes the large intestine to soak up water from your food waste in the absence of water in the system. Causing your stool to become hard and difficult to pass out.

Drinking extra water can help your stool to stay soft. Which is good for easy defecation. 4

Why drinking water is important

5 It Prevents Dehydration

This is a very obvious one. And like we already know from above paragraphs, constipation can lead to dehydration.

Water can help fight overall dehydration.

Dehydration can happen when the quantity of water and fluids leaving the body is greater than what is entering the body.

It is known that even low levels of dehydration can cause headaches, lethargy, and constipation.

Most occurrences of dehydration can be easily reversed by increasing fluid intake.

6. Lubrication Of The Joints

Water makes up the synovial fluid that is known for lubricating joints.

This fluid reduces the friction between joints and helps to maintain healthy tissue and joints.

Synovial fluid is produced by the synovium and coats the tendons in the tendon sheaths and the surface of the synovium in normal joints. 

Synovial fluid is essential for the nutrition and lubrication of articular cartilage and tendons. 5

7. Helps With Digestion

Apart from the creation of saliva which begins the digestion process in the water. Water also aids the whole digestion process.

Drinking water during or after a meal actually aids digestion.

Water enables food to move through the intestines while keeping the intestines smooth and flexible, as well. 6

8. Improve Cognitive Functions

As we already know, lack of water can lead to dehydration.

And dehydration can adversely affect cognitive performance, in children, the elderly, and in young adults. 

Some research evidence points to the fact that having a drink of water results in improved cognition in thirsty adults.

Recent studies in children show that drinking additional water is associated with better performance on tests of memory and attention. 7


The above facts are sufficient reasons why drinking water is important and I hope it was able to help you in your research.
