Why Drink More Water? See 6 Health Benefits of Water

It’s no magic bullet, but the benefits of water are many.

Written by Kathleen M. Zelman, RD, LD, MPH

Americans seem to carry bottled water everywhere they go these days. In fact, it has become the second most popular drink (behind soft drinks). But water lovers got a jolt recently when we heard that a new report had found that the benefits of drinking water may have been oversold. Apparently, the old suggestion to drink eight glasses a day was nothing more than a guideline, not based on scientific evidence.

But don’t put your water bottle or glass down just yet. While we may not need eight glasses, there are plenty of reasons to drink water. In fact, drinking water (either plain or in the form of other fluids or foods) is essential to your health.

“Think of water as a nutrient your body needs that is present in liquids, plain water, and foods. All of these are essential daily to replace the large amounts of water lost each day,” says Joan Koelemay, RD, dietitian for the Beverage Institute, an industry group.

Kaiser Permanente nephrologist Steven Guest, MD, agrees: “Fluid losses occur continuously, from skin evaporation, breathing, urine, and stool, and these losses must be replaced daily for good health,” he says.

When your water intake does not equal your output, you can become dehydrated. Fluid losses are accentuated in warmer climates, during strenuous exercise, in high altitudes, and in older adults, whose sense of thirst may not be as sharp.

Here are six reasons to make sure you’re drinking enough water or other fluids every day:

1. Drinking Water Helps Maintain the Balance of Body Fluids. Your body is composed of about 60% water. The functions of these bodily fluids include digestion, absorption, circulation, creation of saliva, transportation of nutrients, and maintenance of body temperature.

“Through the posterior pituitary gland, your brain communicates with your kidneys and tells it how much water to excrete as urine or hold onto for reserves,” says Guest, who is also an adjunct professor of medicine at Stanford University.

When you’re low on fluids, the brain triggers the body’s thirst mechanism. And unless you are taking medications that make you thirsty, Guest says, you should listen to those cues and get yourself a drink of water, juice, milk, coffee — anything but alcohol.

“Alcohol interferes with the brain and kidney communication and causes excess excretion of fluids which can then lead to dehydration,” he says.

2. Water Can Help Control Calories. For years, dieters have been drinking lots of water as a weight loss strategy. While water doesn’t have any magical effect on weight loss, substituting it for higher calorie beverages can certainly help.

“What works with weight loss is if you choose water or a non-caloric beverage over a caloric beverage and/or eat a diet higher in water-rich foods that are healthier, more filling, and help you trim calorie intake,” says Penn State researcher Barbara Rolls, PhD, author of The Volumetrics Weight Control Plan.

Food with high water content tends to look larger, its higher volume requires more chewing, and it is absorbed more slowly by the body, which helps you feel full. Water-rich foods include fruits, vegetables, broth-based soups, oatmeal, and beans.

3. Water Helps Energize Muscles. Cells that don’t maintain their balance of fluids and electrolytes shrivel, which can result in muscle fatigue. “When muscle cells don’t have adequate fluids, they don’t work as well and performance can suffer,” says Guest.

Drinking enough fluids is important when exercising. Follow the American College of Sports Medicine guidelines for fluid intake before and during physical activity. These guidelines recommend that people drink about 17 ounces of fluid about two hours before exercise. During exercise, they recommend that people start drinking fluids early, and drink them at regular intervals to replace fluids lost by sweating.

4. Water Helps Keep Skin Looking Good. Your skin contains plenty of water, and functions as a protective barrier to prevent excess fluid loss. But don’t expect over-hydration to erase wrinkles or fine lines, says Atlanta dermatologist Kenneth Ellner, MD.

“Dehydration makes your skin look more dry and wrinkled, which can be improved with proper hydration,” he says. “But once you are adequately hydrated, the kidneys take over and excrete excess fluids.”

You can also help “lock” moisture into your skin by using moisturizer, which creates a physical barrier to keep moisture in.

5. Water Helps Your Kidneys. Body fluids transport waste products in and out of cells. The main toxin in the body is blood urea nitrogen, a water-soluble waste that is able to pass through the kidneys to be excreted in the urine, explains Guest. “Your kidneys do an amazing job of cleansing and ridding your body of toxins as long as your intake of fluids is adequate,” he says.

When you’re getting enough fluids, urine flows freely, is light in color and free of odor. When your body is not getting enough fluids, urine concentration, color, and odor increases because the kidneys trap extra fluid for bodily functions.

If you chronically drink too little, you may be at higher risk for kidney stones, especially in warm climates, Guest warns.

6. Water Helps Maintain Normal Bowel Function. Adequate hydration keeps things flowing along your gastrointestinal tract and prevents constipation. When you don’t get enough fluid, the colon pulls water from stools to maintain hydration — and the result is constipation.

“Adequate fluid and fiber is the perfect combination, because the fluid pumps up the fiber and acts like a broom to keep your bowel functioning properly,” says Koelemay.

If you think you need to be drinking more, here are some tips to increase your fluid intake and reap the benefits of water:

1. Have a beverage with every snack and meal.
2. Choose beverages you enjoy; you’re likely to drink more liquids if you like the way they taste.
3. Eat more fruits and vegetables. Their high water content will add to your hydration. About 20% of our fluid intake comes from foods.
4. Keep a bottle of water with you in your car, at your desk, or in your bag.
5. Choose beverages that meet your individual needs. If you’re watching calories, go for non-caloric beverages or water.

Healthy lifestyle

The important role of water lies in the fact that it is the main element in maintaining human life, i. e. an indispensable part of all living things. Only where there is water, there is life. Water is an extraordinary, unique mineral! It is the only mineral that exists in solid, liquid and gaseous states. Water is one of the best energy information carriers. The human body consists by weight of 50-86% water (86% in a newborn and up to 50% in the elderly). According to WHO, 85% of all diseases in the world are transmitted with water.

Water in the human body helps convert food into energy, helps the body absorb nutrients, moisturizes oxygen for breathing, regulates body temperature, participates in metabolism, protects vital organs, lubricates joints, removes various waste products from the body. From a hygienic point of view, one liter of drinking water should not contain more than 0.5 grams of salts. These are mainly bicarbonates, sulfates or chlorides of sodium, magnesium and calcium. Of great importance in determining the quality of water for humans are chemical elements contained in it in negligible concentrations, but, nevertheless, playing an important role in many physiological functions.

These are the so-called trace elements, eg iodine, bromine, fluorine. Their content in a liter of water is expressed in milligrams, but the dosage must be very accurate. So, if a liter of water contains less than 0.5 milligrams of fluorine, then this causes dental caries, and a concentration of fluorine of 1.0-1.5 milligrams per liter can cause dental fluorosis.

However, the other extreme – the absence of salts – worsens the taste and hygienic properties of water. Completely devoid of salt water (distilled) is perceived as tasteless and unpleasant. Physiologically, such water is simply harmful to humans, as it lowers the osmotic pressure inside the cells. Water is necessary for cleansing blood vessels, joints, all organs and systems.

A person loses 1.5 – 2 liters of water per day. So he needs to drink as much water. To saturate our body with water, you need to constantly drink water. According to medical experiments , a person begins to feel thirsty when the amount of water in his body decreases by 1-2% (0. 5-1.0l). A person can live without food for about 50 days if he drinks fresh water during a hunger strike. Without water, he will not live even a week – death will come in 5 days. The correct drinking regime is the preservation of the physiological water balance, i.e. the release and intake of water should be equivalent.

Approximately 40% of the body’s daily water requirement is met with food, the rest we must take in the form of various drinks. If the body receives enough water, then the person becomes more energetic and hardy. At the same time, you can’t focus on whether you are thirsty or not, since this reflex occurs already late and is not an adequate indicator of how much water your body needs. Symptoms of dehydration are: dry skin (may be itchy), fatigue, poor concentration, headaches, high blood pressure, poor kidney function, dry cough, back and joint pain. The norm is 30 ml per 1 kg of weight.

Tea, coffee, artificial drinks, beer – are not able to satisfy the body’s need for natural water. Compliance with the drinking regime for the body is the use of a sufficient amount of water.

Drinking enough water is one of the best ways to stay healthy.

  General information.

  Water is a substance without which life is completely impossible. The human body contains approximately 70 – 90% of water, since many processes occur precisely thanks to water. The use of clean water contributes to the normal functioning of the organs, as well as maintaining the flexibility of the body and the elasticity of the skin. As a rule, the use of a large amount of this substance contributes to the fact that there is a decrease in body weight. This happens not only because the appetite decreases, but also because the water contributes to the fact that the processing of previously formed fat occurs.

  Water is also a heat carrier and thermostat. With the help of this substance, excess heat is absorbed and removed from the body, evaporating through the skin. Also, during a period of strong physical exertion or a hot time of day, a person loses a large amount of fluid. If you drink pure water in time, then it will be absorbed into the blood from the stomach, and the body will cool in time. There is an approximate norm for the amount of fluid intake during the period of physical activity – 1 liter of water per hour.

  It must also be taken into account that the amount of clean water consumption also depends on many factors, such as: age, physical activity, external temperatures, lifestyle. The daily water intake of an adult should be approximately 2. 5 liters. The use of a pure substance leads to the fact that increased protection from stressful situations. This substance must be of high quality, since water that contains harmful substances, their distribution will be throughout the body.

  Carbonated water.

  Sparkling water has both beneficial and harmful properties. It should be borne in mind that the consumption of this product in small doses will not harm an adult, but it can still adversely affect the body. These drinks contain a certain amount of sugar, as well as acid. It is strictly forbidden to use water for people who are prone to obesity or diabetes mellitus, since the components contained in this water simply will not be absorbed by the body. It must be remembered that the consumption of sweet carbonated water will lead to the fact that obesity will begin to develop.

  Natural sparkling water is very rich in carbon dioxide, which is why the product has a much longer shelf life. This type of water can very well help to establish the work of metabolism, but only if it is consumed in small quantities.

  There is also sparkling mineral water , its composition is saturated, and contains almost the entire periodic table, and its taste is a bit peculiar. It is necessary to use this type of water only in agreement with the doctor. If carbonated water is extracted from natural sources, then it has the following properties:

  • saturates the body with minerals and enzymes;
  • affects muscle tone;
  • there is an effect on bones and teeth, as the water contains calcium and magnesium;
  • increases the level of hemoglobin in the blood;
  • improves digestion and increases appetite;
  • diuretic;
  • if the composition includes tarragon, then there is a tonic effect;
  • stabilizes the nervous and cardiovascular system.

  It must be taken into account that people who have diseases from the gastrointestinal tract are strictly forbidden to drink soda, as carbonated water contributes to the fact that there is an increase in gastric juice, and in the presence of gastritis, as it can provoke an existing inflammatory process . Also, the use of carbonated water leads to the fact that the stomach may hurt or flatulence will increase.

  Category of people who are strictly prohibited from drinking sparkling water:

  • children under three;
  • pregnant women;
  • women, during lactation;
  • people who have some degree of obesity.

  Hygienic properties of water.

  It must be remembered that the quality of water directly depends on the person himself. If the water looks fresh and clean, it still has various bacteria. Filtration methods are aimed only at removing foreign particles that have entered the water from outside. It is for this reason that it is always necessary to use various filtering methods.

  In order to determine the organoleptic properties of water, its color, taste, smell and transparency are evaluated. At the time of the descent of water in reservoirs, the quality deteriorates noticeably. The use of hard water may cause skin irritation in certain categories of people. When cooking vegetables in hard water, the vegetables do not boil well. At the present time, in order to minimize the stiffness, special softeners are used.

  When conducting a chemical analysis of water, indirect indicators of its contamination with bacteria are analyzed, for example: nitrogen, chlorides and others. Also, indicators that can pollute water include: nitrates, nitrites and ammonium salts.

  One of the easiest ways to purify water at home is to install the filter. Since bacteria can have a negative effect on the human body, it is very important to use non-chlorine products. If the level of chlorine in the water is higher than normal, then a strong specific smell will be felt. The presence of cloudy water – signals that poor filtration is being carried out. The main task in filtration is to remove from the water small particles of sand, dirt and minerals that can get into the water when swimming.

  Good water must meet the following rules.

  1. The water must be free of parasites and dangerous bacteria.
