Dehydration Effects

Dehydration is the “excessive loss of water resulting in depletion of body fluids” (Grosvenor & Smolin, 2006, p. 282). When the body goes through dehydration there can be many symptoms. Some of these symptoms can include: feelings of nausea, light-headedness, and feeling dizzy. Dehydration can cause symptoms to show more rapidly than any other vitamin deficiency. With other vitamin deficiencies, days or weeks can pass before symptoms are felt by the body (Grosvenor & Smolin, 2006). Symptoms can be seen when dehydrated after only an hour of activity on a hot day. Water is essential to health maintenance because the human body is more than half water. The typical adult’s body weight is about 60% water. This number is even higher in small children and infants. When dehydration sets in, it is important to replace this lost water as fast as possible. Another reason that water is essential to health maintenance is that the body needs a certain proportion of water and dissolved substances. This proportion of water and dissolved substances is necessary so that all the chemical reactions necessary to sustain life continue to function (Grosvenor & Smolin, 2006).
Water has many functions in the body. Muscles are made up of almost 75% water while bones are about 25% water. Water is used as a fluid both inside and outside the cells in a body. Water found in the cells is known as intracellular fluid while water outside the cells is known as extracellular fluid. As a solvent, water is how the body is able to dissolve such necessary substances as: glucose, amino acids, and minerals. Water is used by the body to lubricate and clean internal surfaces. The body also uses water to help cushion certain body parts from the shock of an impact. Body temperature is regulated by water. This is because water can hold heat and water changes temperature…...

...Dehydration Paper SCI/241 October 27, 2012 Water consumption is important to the body in order to maintain optimum health and function properly. The content of this paper will look at a few of the functions of water in the body and what can happen if enough water is not taken in, resulting in dehydration. Following the functions of water, I will discuss dehydration and its stages and symptoms. I will also cover the essential electrolytes in the body, sodium, potassium, and chloride their location, functions, intake recommendations, and the dangers of taking in too much of each. Alcohol and caffeine can have a negative effect on how the body uses water, so I will discuss and explain how both of these substances affect water in the body. Lastly, this paper will discuss ways to avoid becoming dehydrated. Water makes up over half of our body weight. In men, it is approximately 60 percent of their body weight and for women it is approximately 50 percent (Grosvenor & Smolin, 2006). Some of the main functions of water in the body are to help lubricate joints, regulates body temperature, and helps remove waste from the body and aids in the digestion process. When a person experiences joint pain, it is a sign of lack of water. Cartilage within the joints is about 80 percent water and provides a smooth surface for the joints to move on, but that is only the case if enough water is consumed. Lack of water means less lubrication for the joints causing......

...de Dehydration Mary J House Sci 241 University of Phoenix August 12, 2012 Water. People really don’t think about water and the importance of it as much as they should. Water is the one thing that we must give our bodies enough of or we will shrivel away into nothingness and die. We can go for days on end without eating food and we will lose weight, but we will survive. This is not the case with water, we must have it in order to stay alive, we could not go many days with no water. Most people don’t realize that our bodies are actually made up of 60% water. If we do not drink enough water we will dehydrate. If we become dehydrated it means that we have lost more water than we have taken into our bodies. Different things and circumstances cause our bodies to expel water and we must drink enough to replace what we put out. Water plays a huge role in our bodies, water is what enables us to sweat, urinate, water pushes poisons out of our systems when we are sick. There are many ill effects of not getting enough water and dehydrating. People can actually die from dehydration. In order to stay hydrated and keep our bodies functioning properly it is imperative that we drink plenty of water. Water does more than we can imagine in our bodies. Water is what regulates the bodies temperature and it is also a cushion for your joints. Water is what helps us to urinate and have bowel movements. Water can also help us to lose......

...Dehydration is when the body does not have enough water and/or fluids as it should have. Dehydration can be caused by a number of things such as losing fluid, not drinking enough water or liquids daily, or a combination of both. Vomiting and diarrhea can also lead to dehydration. If the body loses too much water or fluids it can lead to severe dehydration and can be life threatening. The symptoms of dehydration range from dry or sticky mouth, urine decreases, eyes become dry and irritated, sunken eyes, and in severe cases of dehydration one may become lethargic or comatose. The best way to overcome being dehydrated is to consume water or fluids in small amounts. If a large amount of water is consumed it may result in vomiting, which is not helping to hydrate the body. If worse case scenarios, to get hydrated, a person could be put in the hospital with IV’s to hydrate the body. It is always important to drink plenty of water and fluids whether a person is healthy or ill. Water is essential to health maintenance because it makes up over 60% of our body weight. In children water makes up around 70% (p. 282). Water is found in three areas according to chapter nine of this week’s reading. Intracellular fluid is inside cells. Extracellular fluid is opposite of intracellular as it is located outside of the cells. It can be found in blood, lymph’s, spinal column, eyes & joints. Interstitial fluid is located between the cells and tissues. The comment “I’m dying of thirst” may be a......

...Dehydration Dehydration Water is nearly a ubiquitous element on our planet, and yet numerous people suffer from low levels of dehydration on a continual basis. While the human body requires many micro and macronutrients, none can be said to be more present in its composition than water. As a result, water is essential to health maintenance. Water’s essential character is a result of its involvement in myriad functions within the human body. When the body is deprived of the water levels that it requires dehydration ensues. Alcohol and caffeine contribute to dehydration and the injurious symptoms that result. Water also serves as a medium for electrolytes such as sodium, potassium, and chloride which maintain water levels and facilitate the proper functioning of the nervous system. Finally, there are many things that people can do to prevent dehydration, but water requirements vary according to many factors. Water is essential to the maintenance of health Water is a necessary component of human life, and the symptoms of its deficiency are one of the quickest to manifest of all nutrients. Water composes around 60% of an average adult’s weight, and this percentage is even higher among children. Whereas the human body is composed of numerous compounds none are more prevalent than water. While the presence of water varies among the different tissues in the body, it is nonetheless found in every bodily tissue. For example, though bone is......

...Introduction Water is an important part of the human body, so much so that nearly 60% of adults’ body weight is made up of water. A human can go many days without food and other nutrients without feeling any serious effects, but if you go even a day without water symptoms of dehydration can begin to appear. A person can even experience symptoms of dehydration after just one hour of exercise on a hot day. Dehydration is Excessive loss of water resulting in depletion of body fluids (, 2006). The effects of dehydration can be very serious in humans and can even lead to death. This paper will examine the functions of water in the body and what happens when the body does not receive the water it needs. Water in the Body Water provides many functions in different areas of the body. Water is used by the body to help dissolve many substances that it needs such as glucose, minerals, and amino acids. Water also helps maintain the proper level of acidity in the body. There are many chemical reactions that take place in the body and water is a part of a number of them. Examples of these include reactions that join smaller molecules together and break larger molecules apart. Reactions of metabolism also occur in water which helps fuel the body. Water also plays a major role in maintaining the body’s temperature. Water holds heat and changes temperature at a slow rate which helps the body maintain a steady temperature. Water in the blood also helps regulate body temperature by......

...Dehydration January 16th 2011 University of Axia Instructor: Water is so essential to health maintenance because our cells are mostly made up of water and because of that all the essential functions of every single cell in our body are carried out in the presence of the universal solvent. A person can call it metabolism, flushing out of, toxic wastes, delivery of nutrients to the cells and also heat to transfer. When you feel hot, you grab a glass of water and you feel better. When you have some food, you take water (or some other liquid) with it, when you sweat during exercise or a steam bath, you feel good because along sweat is essentially water with waste being flushed out of your body. The enzymatic reactions in the cells are also dependent on water. Water is essential to maintain body's homeostasis. If normal water levels aren't maintained, it will affect the osmotic pressure, ion homeostasis and plasma/blood volume as well. Also it is required to excrete waste products from our body (E.g.; urine) and for the regulation of metabolic activities such as enzyme activation. Therefore, water is essential to maintain the body in its normal state. “Water serves many curative functions even in our day-to-day life. In fact, water is very essential for maintaining the proper functioning of our body and sustaining us. It makes up more than half of our body weight and caters to the requirements of various bodily needs. Deficiency of water in the body can affect various......

...To maintain a good health it is essential to consume water. The adult body is consists of nearly 60% water, this makes clear why the organs in the body, for example the brain, kidneys, and heart cannot function properly if they are lacking enough water. Dehydration or excessive loss of water makes the body ‘feel’ uncomfortable and can be life threatening in some cases. After reaching an improved understanding of the magnitude water has with the body, the functions it supports and what transpires when dehydration occurs; an individual will make certain hydration is maintained. Every tissue in the body includes water to some point. Water inside of cells is considered as intracellular fluid whereas water outside of the cells is considered extracellular fluid. The extracellular fluid contributes to the body’s total water weight. A significant aspect to recognize about the water in the body is the water never stops moving or working within the body. As the body realizes a specific place of the body needs water, the body moves the water to the location of need from an area with an elevated concentration of water. This process is referred to as osmosis; an individual’s blood pressure aids the osmosis as it moves the water from area to area of the body. Water is regarded as a solvent for dissolving material needed for appropriate functioning of the body. These functions include: minerals, amino acids, and glucose. The metabolism is aided with water, “equalizing the concentration of...

...Dehydration Amelia D. Sneed Axia College of University of Phoenix SCI/241 The Science of Nutrition Dr. Liam Conner 20 February 2011 Dehydration Water is a necessity to the body for many obvious reasons. Without water a human being would die within a couple of days. The human body is composed of nearly 70% of water; making water the most important element needed for the body to function, next to the oxygen needed to breathe. When the body has an excessive loss of water or depletion of body water people are usually diagnosed as being dehydrated. When a person suffers from dehydrated there are several changes that occur within the body. However the loss of water within the body does not have to be a large percentage, with only two percent depletion of the body’s water supply people can suffer from signs of dehydration (Lewis III, 2008). The onset symptoms of dehydration can be signs of changes in the body such as difficulty focusing, cloudy memory and even the inability to focus on a television or computer screen. An estimated 75% of US citizens have a mild form of dehydration which is also one of the most common causes of daytime fatigue (Merck, 2009). However, some people are not aware of just how important it is to consume an appropriate amount of water on a day to day basis, to maintain the body’s ability to properly function. Water is the bare essential needed to maintain healthiness, as dehydration can prove to be potentially......

...This essay will focus on dehydration, and water in the body how it is function. The reason water essential to health maintenance and what water can do to the body if not enough is obtained. This essay will mention how the body level based on hydration has on alcohol and caffeine. Sodium, potassium, and chloride compare and contrast how these different electrolytes function in the body. I will also explain the steps to take to ensure people not become dehydrated. Dehydration means excessive loss of water resulting in depletion of body fluids (Grosvenor & Smolin (2006). Dehydration is that you lose more fluid than you take in which occurs because there is not enough water and other fluids in the body to function normal. Dehydration can be prevented by drinking about eight- nine glasses of water a day. Water is essential to health maintenance is that over half of your body weight is water. Every cell in our body carries out the presence of the universal solvent. A person sweat during exercise water with waste is flushed out of your body. Water is needed to prevent dehydration this helps to maintain proper metabolism in our body. All the body tissues varying proportions of water is found in 60% of body weight in adults is water, in a child the water percentage is the highest. The functions of water in the body are for digesting food. Water also helps to cushion our joints and prevents shocks in them.

...Dehydration Marty Oliver SCI/241 Version 5 01/30/2012 Abstract I am writing a paper on the effects of dehydration. Included in this paper, I will be explaining the answer of why is water essential to health maintenance? What are the functions of water in the body? What happens to the body when it does not get the water it needs? I will also compare and contrast how different electrolytes-sodium, potassium, and chloride- function in the body. What effects might alcohol and caffeine have on hydration levels in the body? What steps may people take to ensure they do not become dehydrated? Your body cannot function without water. Your body is made up of over 2/3 of your body and is essential for all cells and organs to operate properly. Without it your body will be able to survive only a few days. One of the functions of water in the body is that it flushes toxins, helps in cell functioning, and it helps the throat, nose, and ears function. Water is the seat for the fluids that go around the joints which enables them to move easily without pain. Joints consist of synovial fluid, bursas, ligaments, tendons, synovial membranes, and cartilage. Water is a must for the body to perspire naturally. Sweating is the body’s instrument to maintain the body’s cool when presented with increased anxiety, high activity levels or more anxiety or excessive heat. The body will not decently sweat in response to these stimuli without proper water content. Water is......

...systems to properly perform their necessary functions. Dehydration occurs when more water is lost than what is being taken in. Making sure we have the proper amount of fluids in our cells is vital to ensuring our bodies are able to properly perform their essentially necessary functions. Water acts like a cleanser, helping with the removal of harmful waste and possible deadly toxins. Our blood, which is made primarily of water, is responsible for carrying many nutrients to nearby waiting cells. Our immune system, which contains a fluid called lymph, is also made of water. If our immune system is affected by dehydration, it stops working properly and our body will not be fully capable of fighting off the harmful effects of illness and disease. Water also plays a vital role in the digestive process, by aiding in the break down of foods and liquids and the transportation of those food particles through the entire digestive system. Water is an important component concerning the process of producing and passing excess body waste. Another important role water plays is in regulating normal body temperature. When our internal organs get too warm, we begin the process of perspiration; pushing water out through pores in the skin, in an attempt to remove excess heat and regulate a normal body temperature. If our cell system is not properly, and continually hydrated we may begin feeling the minor symptoms of dehydration almost immediately. The severity of the symptoms......

...Dehydration Keyva Strickland February 18, 2012 Arnetra Gilliam Dehydration can happen for various reasons. Dehydration happens when there is a loss of a significant amount of water in your body. To prevent dehydration, you should make sure you have a significant amount of water in your body. Feeling nausea, dizzy or light headed after or during exercise on a hot and summer day is a sign of dehydration. If someone feels they are dehydrated he or she needs to make sure they are drinking plenty of water, Gatorade, Pedialyte (for children), or popsicles. An important fact to remember is that over half of your body weight is water, so water consumption is very important to avoid dehydration and other illnesses. People can live for years without shelter, months without food, but without water they can only live for days. That shows how important water is to your body and life. Water, next to oxygen is the most important component to sustaining a healthy life. Water is needed by our body’s cells, tissues, muscles and system organs; without water, there will be no life. Water is not a nutrient but is considered an important nutrient and is highly needed to maintain life. The most important role of water is that it is a major component in our blood, and it is important in maintaining body temperature along with the elimination of body waste. Water is required in digestion and metabolism and its function is in the regulation of your body temperature. Besides water......

...Assignment: Dehydration Name: Dorein Pfeil Class: SCI/241 Instructor: Michele Lyons What is dehydration- well the book example tells us that it is when the body is lacking the water to keep the body cool and when that is depleted we then experience what is known as dehydration. But what cause it to happen. Well you know after a work out we are sweating. That sweat is used for cooling the body, without sweat our bodies would overheat and shut down cause our bodies wouldn’t be able to handle the tempreture increase from working out or just being outside on a hot day. Our body is made up of 75% water and it is important that it is maintained in order to keep us cool. One important factor to understand about the water inside the body is that water is an ever moving, working part of our system. Upon the body recognizing the need for extra water in one area, the body will move the water through a process of osmosis, from an area that has a higher concentration. Blood pressure assists the process of osmosis with moving water to different areas of the body. Everything living requires food and water to survive without it the circle of life would be broken and then there would be a fight for survival and eventually when all the resources have been removed then......

...SCI 241 – Week 5 Assignment: Dehydration Christina Doner Our bodies are made up of mostly water. What does that mean? Exactly how it sounds. Water is found in every part of the body; from tissue, to muscle, and in the bone. Bodies depend on water for lubrication, protection, oxygen in the blood (which too is mainly water), in addition to the delivery of nutrients throughout the body. Consequently, water is essential to the survival of human life. Most importantly, bodies do not store water, resulting in obligatory consumption of water on a daily basis to replenish or restore water that was lost through evaporation or urination. Each person’s body is different, so the best way to configure how much water to consume on a daily basis is to ask a doctor or trained physician. Dehydration occurs when a body is losing more fluids than is consumed, and does not have adequate amount of water and other fluids to carry out its normal functions. Water is crucial in maintaining fluid balance throughout the body. Our bodies require adequate amounts of water in our system to regulate body functions and remain healthy. Some examples of what water does for our bodies are; moistening the eyes, help with chewing and break down of food through the mixture of saliva, and to lubricate and protect our bodies joints. So, the most important task of water is its controlling response to chemical reactions. Water is essential in regulating and maintaining our body’s temperature, assuring......

...different body compartments such as the joints and eyeballs against shock by resisting compression. The cushioning effect of water in the amniotic sac protects the fetus as it grows inside a pregnant woman. Blood, which is mostly water, flows through our bodies, delivering oxygen and nutrients to cells and returning waste products to the lungs and kidneys for excretion. In addition, water functions in chemical reactions and helps regulate body temperature. Body temperature is regulated to maintain a temperature of 98.6 degrees. Water holds heat and changes temperature slowly; this allows the body temperature to remain constant. To maintain water balance, the body must receive the same amount of water that is exiting the body. This is very important, so much that our body has different mechanisms to regulate our intake and outtake. When we are in need of water our body lets us know by the sensation of thirst. Failure to sustain an efficient level of water can have life-threatening consequences. The average person can survive about eight weeks without food, whereas without water there is only a survival time of a few days. This is a measurement of how vital water is to our well being. Not consuming enough water can affect the body’s ability to deliver oxygen and nutrients to cells and the removal of waste products, but can ultimately lead to dehydration. Dehydration is when the body does not have the amount of water is should have. Some of the early symptoms......
