Dehydration University of Phoenix SCI 241 February 20 2010 name Dehydration 1 Dehydration 2 Water is an essential nutrient for the body Right up there with oxygen water is pertinent to allow the body to function properly on a daily Water makes up nearly 60 of the body s mass in the average adult and approximately 70 in toddlers and infants University of Phoenix 2010 Without a proper amount of water maintained in the human body dehydration may occur which has devastating effects on the body For this reason it is important for one to consume a proper amount of water daily to maintain a proper level of hydration thereby decreasing the chance of dehydration Why is water so vital to the human body It is essential for the body to perform functions that most people take for granted Nearly every organ in the human body is dependent upon water for its survival Water and oxygen are the two most important substances that allow the body to operate It is wellknown that the body needs oxygen and it is water that transports that oxygen as well as other nutrients throughout the body via the blood stream Water also plays a role in ridding the body of wastes Saliva stomach acids enzymes and other bodily uids could not exist without the presents of water This goes the same for the extraction of wastes excreted from the body via urine and feces Water softens indigestible substances like insoluble fibers allowing content to pass through the intestines easily essentially preventing constipation In addition to assisting with the digestion process water has many other uses Besides ushing toxins and wastes from the body water is essential in regulating body temperature Water can maintain a constant temperature because of its ability to gradually decrease or increase in temperature University of Phoenix 2010 The human Dehydration 3 body maintains a constant temperature of approximately 986 degrees This is accomplished by the bloodstream controlling temperature loss or gain through the skin For example if the body becomes too hot it begins to perspire which allows the body to cool Perspiration occurs when the blood vessels dilate thereby allowing the body heat to be released through the skin On the other hand if the body becomes too cold then the bloodvessels do the exact opposite They constrict and keep as much of the heat within the body as possible In the midst of water contributing to all these functions just as gas in a car it must be constantly refilled Daily activities naturally deplete the body s percentage of hydration Digesting perspiring and even breathing can deplete the body s hydration level The amount of water one must ingest to maintain proper hydration varies however the average person should consume at least eight 80z glasses of water per day If one does not maintain proper hydration dehydrations occurs which could be lifethreatening Without food you could probably survive for about 8 weeks but without water you would last only a few days University of Phoenix 2010 p 285 The reason for this is because it reduces the body s ability to deliver nutrients and oxygen throughout the body because of low bloodvolume and it also prevents the body from properly eliminating waste from the body University of Phoenix 2010 One can prevent dehydration by paying attention to symptoms caused by dehydration Some of the first signs that the body is arriving at the point of dehydration are dry mouth feeling thirsty headache fatigue and dark urine If the body s dehydration level reaches a critical point one may experience nausea loss of coordination and the inability to concentrate or think rationally University of Phoenix Dehydration 4 2010 Electrolytes are category of nutrients transported through the body by water and must be carefully regulated for proper bodily function Electrolytes are essentially electronically conductive ions which can be in the form of acids bases or salts The electrically charged ions are pertinent for normal functioning of the body s organs cells and muscles Muscle contractions and nerve impulses keep the body going day after day and it is electrolytes that allow these contractions and impulses to occur The three main electrolytes are sodium potassium and chloride University of Phoenix 2010 Sodium and potassium are positively charged ions and introduced into the body by the foods and supplements that we eat Both also play a critical role in bodily functions In terms of cells potassium is the stored inside the cells while calcium is stored in the uid surrounding the cells Sodium essentially acts as a security guard thereby regulating the amount of sodium that can enter the cell For example when a nerve cell is stimulated the sodium enters the cell causing an electrical charge that results in a nerve impulse University of Phoenix 2010 The same happens when muscle cell is stimulated Once the cells are no longer stimulated the potassium goes back within the center of the cell and the sodium binds to the outer part of the cell Potassium also has other duties for the human body Potassium must be kept at a constant level because even minor uctuations can lead to serious consequences University of Phoenix 2010 Kidneys are the organs that regulate sodium chloride and potassium primarily The kidneys do this by regulating the levels of electrolytes that are extracted from the body through urine The reason that Dehydration 5 potassium has to be monitored so closely is because high levels can be lethal When blood levels rise body cells begin to take in more potassium to balance out the electrolytes University of Phoenix 2010 The third electrolyte chloride happens to be unlike sodium or potassium however is the most important of them all Unlike sodium or potassium chloride is negatively charged Chloride is very important because it helps balance sodium levels within the body If not for chloride both sodium and potassium levels could get so high that one could have a seizure or irregular heartbeat possibly leading to death Another factor that should be monitored by the person themselves is caffeine and alcohol intake Excessive alcohol or caffeine intake has been linked to lower hydration levels as well as hypertension The commonly known hangover that one gets the next morning after drinking heavily the night before is a result of dehydration University of Phoenix 2010 As far as caffeine is concerned it increases lipolysis dilates blood vessels and increases the amount of urine the body produces which can lead to dehydration Buzzlecom 2010 The bottom line is that alcohol or caffeine in moderation does not cause much harm to the body however excessive use of these substances can lead to sickness and possibly death from dehydration In conclusion to avoid becoming dehydrated the easiest thing to do is to listen to your body If one s mouth is dry urine is dark or any other basic signs present themselves then it is a good idea to drink some water and get oneself hydrated Remember to drink at least eight 80z glasses of water per day and drink alcohol or caffeine in moderation only If possible avoid it at all costs Maintaining a good healthy Dehydration 6 diet along With the recommended daily water intake is much easier than it sounds I found that out quite easily from What I have learned from this course The body is truly a temple and must be taken care of Doing so Will lead to a happier healthier lifestyle Dehydration 7 References Buzzlecom 2010 Negative E ects 0f Ca eine 0n the Body Retrieved February
