Download file to see previous pages The results of dehydration are manifold, as water is related to the provision of oxygen and hydrogen that are important sources of energy production, yet they are most often manifested in general tiredness of the body along with deficiency in cognitive function of the human body. Since it is difficult to define cognition due to the number of psychological and physiological capabilities it comprises, researchers have often broke it divided the term into specific aspects of cognition that are being assessed. These aspects include cognitive functions such as short-term memory, working memory, discrimination between one’s perception, visual-motor function (Szinnai et al., 2005), proficiency in arithmetic, spatial memory and alertness during divided attention (D’Anci et al., 2009). Dehydration however, culminates into impacts on not only the cognitive but also the physical effects on the health of an individual. The impacts have been investigated on both young and old people participating in extensive strenuous exercises (thus dehydrating them), and also by seeking the biochemical basis of physical and cognitive instability. This paper explores the relationship between dehydration and the physical and mental well-being of individuals, in light of five different articles that have researched into the effects of dehydration.
Dehydration has always been of primary concern amongst people who have excessive demand for water and are likely to be unable to adequately compensate for it. Since this category includes mostly sportsmen, a large number of researches have explored the effects that dehydration has on healthy individuals. One such research reported that performance of athletes who competed in a marathon for recreational purposes was either not affected by dehydration or was enhanced in certain people. Although this study seems to be inconsistent with certain widely acclaimed theories, its results are explained by the ...Download file to see next pagesRead More

The review of findings from different studies into the issue will elaborate on the pharmacological effects of DMT available in ayahuasca. Barbanoj et al (2007) sought to establish the potential effects of DMT in the body of men who had been using other psychedelic substances. These authors have prior knowledge that ayahuasca contained DMT and beta carboline alkaloids that possessed monoamine oxidase-inhibiting characteristics. These features accounted for the activity of orally ingested DMT. The...

...functioning have been explained in details in the light of extensive research studies conducted by the health and nutrition experts from time to time (Coutts, p176). The health and nutrition experts have explored the effects of diet supplements upon the functioning of human brain in detailed manner and it has been unveiled by most of the research studies that the benefits of herbal and nutritional diet supplements could not be over looked in maintaining and retaining the cognitive skills. For instance, it has been unveiled that the low level of Vitamin D in the human body could result in decline of the cognitive abilities among the...

...is affected. Some of the early symptoms of dehydration include thirst, headaches, loss of appetite, fatigue, dark colored urine, and dry eyes and mouth. Some of the later symptoms of dehydration include the inability to concentrate, lack of physical energy, nausea, confusion, and disorientation. To function the human body requires the transmission of nerve impulses and the contraction of muscles. These activities occur due to the movement of electrically charged ions dissolved in water. The ions that conduct electrical current are called electrolytes. The three main electrolytes in the human body are sodium, potassium, and chloride. Sodium and potassium...

Dehydration

...The Effects of Dehydration The importance and function of water in health maintenance Water is an essential requirement and component in living organisms. Water comprises approximately 60% of the human body weight. Approximately two-thirds of total body water can be found in the intracellular fluids while one-third is in the extracellular fluid. The extracellular water is made up of the interstitial fluid (eighty percent) and the blood plasma, where blood cells are suspended (Widmaier, Raff, & Strang, 2003). The functions of water can be related to its unique physical and chemical properties. Due to its polar nature, it is the universal...

Abstract: Dehydration of Cyclohexanol

...Dehydration of cyclohexanol College: The experiment was carried out using a distillation flask. An efficient dehydrating agent was employed. The dehydrating agent was to remove the OH group from the cyclohexanol leading to the formation of cation as the intermediate product and thereafter remove a hydrogen atom from the cation resulting in the formation of cyclohexene. The mixture of approximately 10g of cyclohexanol, 3 mL of 85% phosphoric acid and 1-2 boiling chips was put inside the distillation flask and water was applied as it was heated. The cyclohexene was removed from the flask by use of pipet. The mass of the cyclohexene was determined. The results proved that an acid can be used...
