Chapter 1 INTRODUCTION Our body needswatertohelp with functionssuch astemperatureregulation, digestionandprocessingfood, carrying nutrients and waste products throughout the body and participates in metabolic reaction. Withallthese bodyfunctionsdemandingforwater,water balance of the human body drops by a few percent depending on daily activities that are presented. As the water fluid balance drops, the human body experiences dehydration. Dehydration is an alarming health condition because the human body tries to compensate for this decrease of fluids by increasing the heart rate and making blood vessels constrict in order to maintain blood pressure and blood flow to the vital organs of the body.The human brain sends an indicator which is the simulation of thirst triggered by two factors which areincrease in sodium levels and decrease in blood flow to release hormones that would urge the intake of water to our body. But due to adaptation of the human body throughout its daily activities and exposure to different environment, the human body tends to be less sensitive to water deprivation thus resulting to dehydration.The results from the journal “Unrecognized chronic dehydration in older adults: examining prevalence rate and risk factors,” which studied elderly people, shows that 48% of the patients manifests chronic dehydration. This result tells that unrecognized dehydration is real and possess serious health problems if not addressed. The current methods for detecting dehydration in hospitals are by urine analysis and blood samples.Theresearchersfoundoutotherwaysofdetecting dehydration in adifferentfactor from other patents. One of the factor in determining water fluid balance is the bioelectric impedance of the body. Thepatententitled“Dehydration condition judging apparatus by measuring bioelectric impedance,” is an electronic device that sends an alternating current signals through the parts of the 2

body, and voltage measuring electrodes accept the signals and interpret the bioelectrical impedance to its equivalent analyzed fluid value from the microprocessor. The other factor in determining water fluid balance is the sweat composition when perspiring. The patent entitled “Wearable electrochemical sensor for the real-life measurement of sweat sodium concentration,” is an electronic device where ion selective electrodes inspect the sodium ions and chloride ions from the sweat pads, and interpret its values to determine the exact water fluid balance reading.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
