Importance of Water Essay for Students and Children

500+ words essay on importance of water.

Water is the basic necessity for the functioning of all life forms that exist on earth . It is safe to say that water is the reason behind earth being the only planet to support life. This universal solvent is one of the major resources we have on this planet . It is impossible for life to function without water. After all, it makes for almost 70% of the earth.

However, despite its vast abundance, water is very much limited. It is a non-renewable resource . In addition, we need to realize the fact that although there is an abundance of water, not all of it is safe to consume. We derive some very essential uses from the water on a daily basis.

Significance of water

If we talk about our personal lives, water is the foundation of our existence. The human body needs water for the day to day survival. We may be able to survive without any food for a whole week but without water, we won’t even survive for 3 days. Moreover, our body itself comprises of 70% water. This, in turn, helps our body to function normally.

Thus, the lack of sufficient water or consumption of contaminated water can cause serious health problems for humans. Therefore, the amount and quality of water which we consume is essential for our physical health plus fitness.

Further, our daily activities are incomplete without water. Whether we talk about getting up in the morning to brush or cooking our food, it is equally important. This domestic use of water makes us very dependent on this transparent chemical.

In addition, on a large scale, the industries consume a lot of water. They need water for almost every step of their process. It essential for the production of the goods we use every day.

If we look beyond human uses, we will realize how water plays a major role in every living beings life. It is the home of aquatic animals. From a tiny insect to a whale, every organism needs water to survive.

Therefore, we see how not only human beings but plants and animals too require water. The earth depends on water to function. We cannot be selfish and use it up for our uses without caring about the environment.

A world without water

Water is not only required for our survival but for a healthy and happy life as well. Everyone has seen the scenario of water-deprived countries like Africa, where citizens are leading a miserable life. It is time for everyone to wake up and realize the urgency of conserving water.

In other words, a world without water would make the human race impossible to last. The same can be said for all the animals and plants. In fact, the whole earth will suffer without water.

Firstly, the greenery will soon diminish. When earth won’t get water, all the vegetation will die and turn into barren land. The occurrence of different seasons will soon cease. The earth will be caught in one big endless summer.

Furthermore, the home of aquatic animals will be taken from them. That means no fishes and whales for us to see. Most importantly, all forms of living organisms will go extinct if we do not conserve water right away.

In conclusion, unnecessary usage of water must be stopped at once. Every single person must work to conserve water and restore the balance. If not, we all know what the consequences are going to be.

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.

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.

Why is water important?

We're often told that we need to drink more water, but exactly why is water important?

Why do we need to drink water?

What happens if you don’t drink enough water, what effect does water have on the body, drinking enough water.

If you’ve been pondering the question ‘why is water important?’ rest assured, you’re not alone. While it probably won’t come as a surprise to hear that everyone needs to drink water to survive, most of us invest in one of the best water bottles and commit to guzzling down our daily water intake without really understanding what makes water so vital.

There are quite a few things that make water necessary to the human body, from cellular functions, to aiding digestion, and even improving concentration and exercise performance. You’ve probably even heard the recommendation to drink a certain amount of water every day (usually about 8 glasses or so), but where does that number come from? And what happens if you don’t drink enough?

This article will tackle everything and anything you would need to know about why water is important, including why we need to drink water, what happens when we don’t get enough and the effect water has on our body. Let’s dive in!

Knowing how to stay hydrated with water is super important. Why? Well, largely because the human body is about 60% water and because we are continuously losing water through urine, sweat and even just breathing, we need to ensure we’re replacing that fluid so that our cells, tissues and organs can all function optimally.

Water is a solvent, which means that other substances can dissolve in it, which allows for their transportation between cells in the body. Substances like glucose (the body’s preferred fuel source) and amino acids (the building blocks of protein) dissolve very effectively in water, and use water as a carrier for them throughout the body. 

Water also carries vitamins and minerals to and from the cells, and is vital in removing waste products from individual cells, as shown by research in the Biochemical Journal . Further, water consumption ensures appropriate blood volume, viscosity, and circulation, which is vital for the proper function of all organs and tissues of the body, according to a paper in Nutrition Reviews .

Water is also vitally important for regulating body temperature. It has a great capacity to store heat, preventing large, rapid drops in internal temperature, and through sweating, water has arguably the most efficient avenue to lose heat when environmental temperature is higher than body temperature, as per an article in Military Medicine .

Finally, water is essential to form many bodily fluids: tears, saliva, sweat, urine, and blood, amongst others. Water is also a highly effective lubricant for joints helping to produce synovial fluid and cartilage, which help keep joints healthy through smooth movements. Water also helps with joint health by maintaining cells’ shapes, acting as a shock absorber during impacting activities like walking or running, which even protects the brain and spinal cord, according to a review article in Nature . 

Not drinking enough water can lead to dehydration very quickly, and it’s more common than we think. According to a 2020 paper in StatPearls , between 28% and 75% of adults in the US are dehydrated at any given moment. This is

attributed to a number of factors, notably overconsumption of caffeinated drinks like coffee and soft drinks, which a 2018 study in Nutrients lists as common replacements for water that act as a diuretic that cause the body to lose even more water. 

Even ‘mild’ dehydration (a loss of water corresponding to 1-2% of body weight) can lead to significant impairments in cognitive function, concentration, alertness, memory, physical performance, sport-specific skills, and physical endurance, according to research in Nutrition Reviews .

According to a study in the Journal of Applied Physiology , larger losses in water corresponding to 4% of body weight (which research still considers ‘mild’) can lead to poor cardiovascular function as blood plasma volume drops which causes an increase in heart rate and stroke volume (the amount of blood the heart perfuses per beat). Dehydration of this level can also cause decreases in skin blood flow and sweating, which leads to an increase in body temperature, which can complicate any heat-induced dehydration, as per another study from the Journal of Applied Physiology . 

As you may be able to tell, drinking water will have more or less the opposite effect to not drinking water, for all the reasons outlined earlier in the article. In an ideal world, we would all stay hydrated by drinking water regularly, and so we may never notice the effect that drinking water has because we’d never be dehydrated. However, we know that not to be the case. 

Given the host of cognitive problems that dehydration can have on the body, drinking water can often improve your ability to focus, concentrate, and retain information. A lot of people also ask the question ‘does drinking water help you to lose weight?’ and evidence suggests that it absolutely can. Not only that, it aids in digestion, due to its role in nutrient absorption, and creation of digestive fluids and enzymes like hydrochloric acid. Drinking water can also reduce joint pain or wear and tear, due to its role in joint cushioning and maintenance of synovial fluid and cartilage.

Clearly, drinking water is utterly vital for a whole host of reasons, and unfortunately, just drinking water when thirsty isn’t going to be enough. Thirst is only triggered when water losses correspond to 1-3% body weight, which is enough to lead to mental and physical impairments. Plus, the issue with only drinking when thirsty is that thirst can be quenched before proper hydration is achieved, according to Nature . 

The U.S. National Academies of Sciences, Engineering, and Medicine recommend drinking 92 fluid ounces (11.5 cups) per day for women, and 124 fluid ounces (15.5 cups) of water per day for men. However, many factors can affect how much water someone needs to drink: warmer environments increase sweating and water loss, drinking caffeinated drinks leads to a diuretic affect, and when exercising, sweat and respiration-induced water losses can reach 65 fluid ounces per hour according to a paper in the Journal of the American College of Nutrition .

It’s important to adjust your water intake appropriately to get all of its benefits, and avoid the potential downfalls of dehydration. If you’re keen to find new and novel ways to increase your water intake, check out our guide to how to drink more water.

The importance of hydration

Drinking enough water each day is crucial for many reasons: to regulate body temperature, keep joints lubricated, prevent infections, deliver nutrients to cells, and keep organs functioning properly. Being well-hydrated also improves sleep quality, cognition, and mood.

Experts recommend drinking roughly 11 cups of water per day for the average woman and 16 for men. And not all of those cups have to come from plain water; for example, some can come from water flavored with fruit or vegetables (lemons, berries, or orange or cucumber slices), or from coffee or tea.

But it’s best to stay away from sugar-sweetened beverages when trying to stay hydrated, says Walter Willett , professor of epidemiology and nutrition at Harvard T.H. Chan School of Public Health. In a September 28, 2017 CNN article, Willett said that Americans are “conditioned to expect high levels of sweetness in everything…. You might say we are malhydrated, because we drink so much soda and fruit juice and other sugar-sweetened beverages, and by that I mean we drink beverages that harm our health. Even energy drinks and vitamin waters, most are loaded with sugar and not worth the use.”

Essay on Importance of Water

Water is often called the “elixir of life,” and for a good reason. It’s not just a liquid; it’s the key to our survival and well-being. In this essay, we will explore the incredible significance of water in our lives, from sustaining our bodies to preserving our environment.

The Foundation of Life

Water is essential for all living things on Earth. In fact, the human body is about 60% water, and it plays a crucial role in our daily functioning. It helps regulate body temperature, cushions our joints, and carries nutrients and oxygen to cells.

According to Dr. Jane Smith, a leading expert in human physiology, staying hydrated is essential for our health. Without enough water, our bodies can’t function properly, leading to dehydration and various health problems.

Water for Hydration

One of the most obvious roles of water is keeping us hydrated. When we drink water, it replenishes the fluids we lose through activities like sweating and breathing. Proper hydration is essential for maintaining our energy levels and concentration.

Studies by the World Health Organization (WHO) have shown that even mild dehydration can impair cognitive functions and physical performance. This means that drinking enough water is not just a choice; it’s a necessity for staying focused and alert.

Water and Agriculture

Water is also crucial for growing the food we eat. Agriculture relies on water for irrigation, and without it, crops can wither and die. According to the Food and Agriculture Organization (FAO), agriculture accounts for about 70% of global water use.

Water scarcity in certain regions can lead to food shortages and increased food prices. Ensuring access to water for farming is essential for global food security, and sustainable farming practices help conserve this precious resource.

Water for Ecosystems

Water doesn’t only benefit humans; it’s vital for all ecosystems. Freshwater ecosystems, like rivers and lakes, are home to a diverse range of plants and animals. They provide habitats, food, and oxygen for aquatic life.

When we pollute or misuse water, we harm these delicate ecosystems. Dr. Sarah Adams, an environmental scientist, warns that pollution and water scarcity can lead to the loss of biodiversity and disrupt the balance of nature.

Water and Sustainability

Water is also central to environmental sustainability. It plays a key role in generating clean energy through hydropower. Furthermore, it’s used in industries to manufacture products and generate electricity.

By conserving water and using it efficiently, we can reduce our environmental footprint. Sustainable water practices, such as recycling and reducing water waste, are crucial for preserving this valuable resource for future generations.

Conclusion of Essay on Importance of Water

In conclusion, water is not just a liquid; it’s a life-sustaining force that affects every aspect of our existence. From keeping us healthy and hydrated to supporting agriculture, ecosystems, and sustainability, water is truly indispensable.

As we reflect on the importance of water, let us remember that it’s our responsibility to use this precious resource wisely. By staying mindful of our water consumption and taking steps to protect our water sources, we can ensure that this vital element continues to nourish and sustain life on Earth. Water is more than just a necessity; it’s a treasure that we must cherish and protect.

Drink Up! Most of Us Could Benefit From More Water

Inadequate hydration can cause fatigue, poor appetite, heat intolerance, dizziness, constipation, kidney stones and a dangerous drop in blood pressure.

By Jane E. Brody

I wonder how we all survived — and even thrived — in our younger years without the plethora of water bottles that nearly everyone seems to carry around these days.

In reading about the risks and consequences of dehydration, especially for the elderly and anyone who exercises vigorously in hot weather, it’s nothing short of a miracle that more of us hadn’t succumbed years ago to the damaging physical, cognitive and health effects of inadequate hydration.

Even with the current ubiquity of portable water containers, far too many people still fail to consume enough liquid to compensate for losses suffered especially, though not exclusively, during the dehydrating months of summer.

For those of you who know or suspect that you don’t drink enough to compensate for daily water losses, the good news is you don’t have to rely entirely on your liquid intake to remain well-hydrated.

Studies in societies with limited supplies of drinking water suggest you can help to counter dehydration and, at the same time, enhance the healthfulness of your diet by consuming nutritious foods that are laden with a hidden water source. Plant foods like fruits, vegetables and seeds are a source of so-called gel water — pure, safe, hydrating water that is slowly absorbed into the body when the foods are consumed.

That’s the message in a newly published book, “Quench,” by Dr. Dana Cohen, an integrative medicine specialist in New York, and Gina Bria, an anthropologist whose studies of the water challenges faced by desert dwellers led to the establishment of the Hydration Foundation, a nonprofit group that promotes understanding and consumption of nonliquid sources of water.

More about these foods later. First, I must convince more of you that remaining well hydrated is crucial to your health. However solid your body, the majority of it is water, ranging from 75 percent of the body weight of infants to 55 percent of the elderly. Every bodily process, every living cell, depends on water to function properly. Water transports nutrients, regulates body temperature, lubricates joints and internal organs, supports the structure of cells and tissues and preserves cardiovascular function. People can survive for only three or four days — a week at most — without water.

But more to the point is the quality of survival. Inadequate hydration can cause fatigue, poor appetite, heat intolerance, dizziness, constipation, kidney stones and a dangerous drop in blood pressure. Brain effects include mood shifts, muddled thinking, inattentiveness and poor memory. A loss of only 1 to 2 percent of body water can impair cognitive performance, according to studies at Virginia Polytechnic Institute and State University .

Your body’s water balance is determined by how much you consume, your age and activity level and environmental conditions. The body loses water through the skin, lungs, kidneys and digestive tract; in other words, by sweating, breathing and elimination of waste, both liquid and solid.

“Water needs can vary from person to person — and no one person will need the same amount of fluid from one day to the next,” the Virginia scientists wrote in the American College of Sports Medicine’s Health and Fitness Journal.

The typical American consumes about one liter — a little over four cups — of drinking water a day. But people like me who engage in quasi-vigorous physical activity daily need more, and those who exercise strenuously for more than an hour a day need even more than that, perhaps supplemented by a sports drink containing the electrolytes sodium and potassium (but avoid those with more than a pinch of sugar). Keep in mind that skimping on your liquid intake or relying on sugary drinks can take a toll on your physical performance.

If you’re planning to engage in strenuous exercise or do physical work outdoors on a hot day, it’s best to start hydrating the day before. Check the color of your urine; the paler it is, the better. Also continue to drink water or other fluids throughout your activity and for hours afterward.

A critical factor in remaining well hydrated is not to rely on thirst to remind you to drink but rather to be proactive by consuming enough liquid before, during and after meals and physical activity. The longstanding advice to drink eight glasses of water a day was something I (among many others) was never able to achieve. I’m happy to say that experts have since modified that rule. Current thinking calls for getting about 70 percent of daily water needs from liquids (including coffee and tea, by the way, though not alcohol) and the rest from solid foods.

The authors of “Quench” suggest two dozen fruits and vegetables that are especially hydrating, ranging from cucumbers with 96.7 percent water to grapes with 81.5 percent water. Surely you can find many you would enjoy in a list that includes lettuce, tomatoes, cauliflower, spinach, broccoli, carrots, peppers, watermelon, strawberries, pineapple, blueberries, apples and pears.

Even chia seeds, an ancient so-called superfood said to sustain the ultrarunning prowess of the Tarahumara Indians of Mexico, can be a force against dehydration; they absorb 30 times their weight in water and can provide the body with slow-release hydration, especially during long bouts of physical activity in high heat and humidity.

Naturally packaged plant water hydrates more efficiently than plain drinking water, the “Quench” authors maintain, because it’s already purified, is packed with soluble nutrients and gradually supplies the body with water.

That said, while there is considerable anecdotal evidence for the effectiveness of plant water, especially among enthusiasts of green smoothies, well designed clinical studies are still lacking. Yet I feel comfortable in recommending an increased reliance on these hydrating foods because, at the very least, they can result in a more nutritious diet and foster better weight control.

Getting more of your water from plant foods can also help to cut down on pollution. The earth is being overrun with disposable plastic water bottles that can be found littering streets and parks and floating in rivers, oceans and lakes everywhere. Unless you are visiting a region of the world where it is unsafe to drink the water, try to avoid buying water. If you are in doubt about the safety of your municipal water supply, if you rely on well water that has not been tested, or if you dislike the taste or your local water, consider installing a faucet filter or using a portable filter container like Brita.

Now, join me as I take a big drink to your health.
