Water means Life. Water is a prime natural resource. It is a basic need for humans and a precious asset that living beings have. Water is equally vital for the survival of the plant and animal kingdoms. Soil needs water for sustaining plants. The water cycle is essential for ecological balance too. Though a big portion of the Earth is covered with water, only a small portion of it can be used for various human activities. So we need to be judicious and rational, regarding the usage of water.

Why is water important for our bodies?

Water is important for our body for the following reasons.

Above 70% of our body contains water so it is pivotal for the human race to survive.

Water helps in regulating our body temperature.

Water helps in the digestion of solid food.

It also keeps our skin healthy and hydrated.

Water helps in excreting waste from our body through sweat, urination, and defecation. So replenishing the water in our body is essential to prevent dehydration.

Drinking water also helps in reducing calories and maintaining body weight because it can increase the rate of metabolism.

Water consumption lubricates the joints, spinal cord, and tissues.

Importance of Water

All living organisms, plants, animals, and human beings contain water. Almost 70% of our body is made up of water. Our body gets water from the liquids we drink and the food we eat. Nobody can survive without water for more than a week. All plants will die if they do not get water. This would lead to the death of all the animals that depend on plants for their food. So the existence of life would come to an end.

Role of Water In Life Processes

Water plays an important role in most of the life processes by acting as a solvent. The absorption of food in our body takes place in solution form with water as the solvent. Also, many waste products are excreted in the form of solutions through urine and perspiration.

Water helps in regulating our body temperature. In hot weather, we drink a lot of water. This maintains our body temperature. Also, water evaporates from the surface of our body as sweat. This takes away heat and cools the body.

Water is essential for plants to grow. Plants need water to prepare food. They also absorb dissolved nutrients from the soil through their roots.

Aquatic plants and animals use the nutrients and oxygen dissolved in water for their survival.

Uses of Water In Everyday Life

Water is used for drinking, washing, cooking, bathing, cleaning, in our day-to-day life.

It is used to generate electricity in hydroelectric power stations.

Water is used for irrigating fields and in the manufacture of various products.

Other Uses of Water

Water serves as a means of transportation for goods and people.

It provides a medium for recreational sports such as swimming, boating, and water skiing.

Water is also used to extinguish fires.

Importance of Oceans

Oceans are of immense use to man. They are useful in many ways, directly and indirectly. They not only play a significant role in the climate of adjoining countries but also serve mankind in many ways. They are a storehouse of several resources.

An ocean is a major source of water and forms a major part of the water cycle. Oceans contribute water vapor to the atmosphere and we get the same in the form of precipitation.

The oceans are the biggest storehouse of edible forms of marine food, fish being most important. In addition to food, sea animals provide other products like oil, glue, etc.

Oceans have enormous mineral and chemical wealth. A variety of dissolved salts like sodium chloride (common salt), magnesium chloride, and potassium chloride are found in plenty in the oceans.

Oil and gas are important fuels obtained from oceans.

Importance of Lakes and Rivers

Economic and industrial development

Water storage

Hydroelectric power generation

Agricultural purposes

Modern multipurpose dams

Source of food

Source of minerals

Tourist attractions and health resorts

Rivers provide fresh drinking water

Ports can be built on them as they form good natural harbors

Major Concerns

Although our planet Earth is covered with 71% percent of water and 29% of the land, the fast-growing contamination of water is affecting both humans as well as marine life. The unequal distribution of water on the Earth and its increasing demand due to the increasing population is becoming a concern for all.

Water pollution makes it difficult for marine animals to sustain themselves.

Covering over 71% of Earth’s surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprising Hydrogen and Oxygen, life on Earth would be non-existent.

We are slowly but harming our planet at a very alarming rate.

Characteristics of a Good Essay.

It must be brief: As pointed out earlier, a good essay must be short, and also to the point. So, if students are writing an essay on the importance of water it must only deal with the water, and anything which does not directly serve the purpose must be excluded.

Must cover the whole topic: Though it may seem a little contradicting to the first point, what is meant by covering the whole topic is that the maximum number of aspects dealing with the importance of water must be covered in this essay. For instance, water is important for all living organisms and not just humans, and so the same has to be covered in one or the other way in the essay on the importance of the water.

Must be to the point: The essay must remain true to the central idea of the topic, which is the importance of water in this case. Hence, almost all the sentences written in the essay must serve the main topic in one or another way. And also, writing should not be vague or ambiguous, or illogical.

Human beings should realize how important and precious water is. At the individual level, you can be more responsible and avoid wasting water so that our future generation can make the best use of this natural resource abundantly.

Liquid water is essential for life as we know it, i.e. carbon-based life. Although other compound-solvent pairs that could exist in very specific physical environments could be envisaged, the elements essential to carbon and water-based life are among the most common in the universe. Carbon molecules and liquid water have physical and chemical properties that make them optimised compound-solvent pairs. Liquid water is essential for important prebiotic reactions. But equally important for the emergence of life is the contact of carbon molecules in liquid water with hot rocks and minerals. We here review the environmental conditions of the early Earth, as soon as it had liquid water at its surface and was habitable. Basing our approach to life as a “cosmic phenomenon” (de Duve 1995 ), i.e. a chemical continuum, we briefly address the various hypotheses for the origin of life, noting their relevance with respect to early environmental conditions. It appears that hydrothermal environments were important in this respect. We continue with the record of early life noting that, by 3.5 Ga, when the sedimentary environment started being well-preserved, anaerobic life forms had colonised all habitable microenvironments from the sea floor to exposed beach environments and, possibly, in the photic planktonic zone of the sea. Life on Earth had also evolved to the relatively sophisticated stage of anoxygenic photosynthesis. We conclude with an evaluation of the potential for habitability and colonisation of other planets and satellites in the Solar System, noting that the most common life forms in the Solar System and probably in the Universe would be similar to terrestrial chemotrophs whose carbon source is either reduced carbon or CO 2 dissolved in water and whose energy would be sourced from oxidized carbon, H 2 , or other transition elements.

Why Is Water So Important? Here’s What You Need to Know

How water works in your body, how much water do you need, how to stay hydrated.

Water is a major component of your body, accounting for 50–60% of your total weight. It is vital for many important body functions, from flushing out waste to lubricating your joints.

Your body constantly loses water throughout the day through urinating, sweating, and breathing. You should consume enough water from foods and beverages daily to prevent dehydration .

This article covers research-backed reasons why your body needs water and how much you need each day.

All body cells, organs, and tissues require water to function. Generally, a person can only survive without water for a few days.

It Maintains a Normal Body Temperature

Water regulates our internal temperature by distributing heat throughout the body and cooling it through perspiration (sweat).

When the body becomes too hot, it loses water through sweat . The evaporation of sweat from the skin cools the body, keeping its temperature within a normal range.

If a person becomes dehydrated, they can't produce enough sweat to cool their body. This can cause the body's temperature to reach dangerous levels, leading to heat stroke .

Avoid dehydration by drinking plenty of water if you're working outside or sweating more than usual.

It Protects Your Joints, Spinal Cord, and Other Tissues

Water acts as a lubricant in the mouth (through saliva ) and the eyes (through tears) to help prevent dryness. It's necessary to produce synovial fluid , which lubricates, cushions, and protects the joints.

Water also helps protect the spinal cord and prevents injuries by increasing tissue flexibility and elasticity.

It Transports Nutrients and Gets Rid of Waste

As a major component of blood, water helps transport nutrients and oxygen to cells throughout the body. Water also helps carry waste from the body for excretion through perspiration, urination, and bowel movements.

The kidneys need water to effectively filter waste from the blood and flush it from the body as urine. Staying adequately hydrated helps prevent kidney stones and urinary tract infections (UTIs) , which can harm the kidneys.

Prevents Dehydration

Drinking water daily can help prevent dehydration, a condition that occurs when you lose more fluids than you absorb.

Early signs of dehydration include:

Feeling thirsty
Dark-colored urine
Urinating less than usual

Because water is involved in so many body functions, dehydration can eventually cause life-threatening symptoms, including:

Rapid breathing
Rapid heartbeat
Inability to urinate

People who exercise in the heat, work outdoors, or have certain health conditions that cause them to urinate or sweat more than usual are at a greater risk of dehydration.

It Aids Digestion

Your saliva is primarily made up of water. Saliva is a digestive juice that moistens food, allowing it to move easily through the esophagus into your stomach. Saliva also contains enzymes that help break down starches in food.

As the digestive process continues, water helps break down food, allowing your body to absorb nutrients. Water also makes bowel movements easier.

It Protects Against Chronic Illness and Boosts Longevity

Adequate hydration is linked to healthy aging and longevity. One potential reason for this is that decreased water intake can lead to higher sodium concentrations in the blood, which raises the risk of chronic disease.

Studies suggest that adults who stay hydrated are healthier and less likely to develop chronic diseases, including heart and lung disease . Well-hydrated adults also seem to live longer than adults who don't consume enough fluids.

It Improves Mood and Cognitive Function

Dehydration may cause fatigue and confusion and may be linked to symptoms of anger and depression. In a small study, it was linked to poor cognitive function, potentially affecting attention span and working memory.

One study of young adults looked at the effects of water on cognitive performance and mood after 12 hours of water restriction. Researchers found that 200 milliliters of water improved thirst, anger, fatigue, and overall mood. However, 500 milliliters was optimal, improving mood and cognitive performance.

The amount of water you need depends on several factors, including age, sex, activity level, and health status.

For healthy individuals, the adequate daily water intake is around 11.5 cups for women and about 15.5 cups for men. This includes fluids consumed from all foods and beverages.

Experts estimate that most people get around 20% of their daily water intake from food. This means women should drink about 9 cups of fluid daily, while men should aim for 13 cups to maintain adequate hydration.

People who live in warmer climates, are more physically active, or are experiencing an illness that causes fever and/or diarrhea or vomiting have increased fluid needs.

One easy way to see if you are properly hydrated is to check the color of your urine. If you are drinking enough water, your urine will be pale yellow. If it is dark, you may need to increase your consumption.

Individuals with heart failure or kidney disease may need to limit their fluid intake.

Can You Drink Too Much Water?

Drinking too much water can lead to water intoxication or overhydration, which occurs when the kidneys cannot flush out excess water. This can cause a medical emergency due to decreased sodium concentrations in the blood ( hyponatremia ). To avoid water intoxication, do not drink more than 48 ounces, or six cups, per hour.

If you find it challenging to stay hydrated, here are some helpful tips to keep in mind:

Keep a reusable water bottle with you and refill it throughout the day
Choose water or sparkling water instead of sugary beverages
When you feel thirsty, drink water
Change things up by squeezing fresh lemon or lime into your water or adding a few berries or cucumber slices
Snack on water-rich fruits and vegetables , including watermelon, cantaloupe, lettuce, and celery, throughout the day
Keep track of your water intake by using a water tracker app
Drink water with all meals

Water is vital for your health. It is necessary for temperature regulation, digestion, nutrient absorption, and body waste removal. Drinking water daily can prevent dehydration, a condition that can cause mood and memory problems, constipation, and kidney stones.

People who work in high temperatures, exercise at high intensities, or are sick are at a greater risk of dehydration. Talk to a healthcare provider or registered dietitian to determine the right amount of water for you.
