The scholarly article, Hydration Assessment Techniques by Lawrence Armstrong researches the various ways to compute hydration and hopes to present guidelines for various conditions. The are many ways water can be lost throughout the body. Water can be lost through “the lungs, skin, and kidneys”, through cell circulation, through exercise, through illnesses, anf through lack of water consumption, just to name a few (Armstrong 2005, p.40). Armstrong describes water is measured by “Total body water”, “extracellular volume”, “intercellular volume” and “plasma volume” (2005, p.41). There are about ten approaches to computing hydration. The most useful forms of testing to scientist and forensics is the “Neutron activation analysis” (Armstrong, 2005, p.42). This test uses an atom that contain extra nuclear energy called “radionuclide” to determine the amount of any substance in the body (Armstrong 2005, p. 42). This test is not commonly used because of the costs and lack of experienced labs. Another form of hydration testing Armstrong suggests, is “Bioelectric impedance” (2005, p.42). This testing involves sending “electric currents” into the body and assess the bodies configuration. Factors such as “skin …show more content…
In order to understand how hydration affects learning and memory, I must first understand how hydration is measured and how hydration may be lost. This article provides me with all of those answers. Armstrong presents information of various forms of testing which is very useful. I know the information Armstrong provides is credible because he holds a Ph.D, there is a long list of references used, the work was published in 2005, his diction is highly educational, and he provides original work and originals charts. Armstrong administers his views clearly, which makes the information easier to understand. For all these reason, I would recommend this article to a friend interested in
