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 fact that this may be the case because performance and dehydration may include more physiological factors than the study had taken into account. Similarly, the cognition evaluation tests resulted in no significant results between dehydration and cognitive function. Although the research explains that the conclusions may be affected due to the fact that dehydration in the winter does not have a significant impact on cognition, it also expresses the limitation of the fact that the athletes evaluated had similar ages(Mahon et al. Moreover, even though the overall results of this research were not as conclusive as those of several previous researches, Mahon et al. did report an increased “incidence of various well-being measures such as headaches, cramps and nausea” (Mahon et al., 2014 p.Although majorly inconclusive, the research does point towards the lack of physical well-being because of dehydration.More conclusive results were derived from other similar investigations involving athletes. Although it was short-term memory that appeared to be elevated during times of dehydration, the athletes’ vigilance attention was deemed to be decreased as a result of dehydration (D’Anci et al. The conclusion that D’Anci et al. derived stated that “mild dehydration influences cognition”, but “mood may be more sensitive to negative fluid balance than cognitive performance” (D’Anci et al., 2009, p.This study therefore goes on to show that dehydration not only affects the physical but also the emotional status of a human’s health.A third research which included the assessment of similarities between the psychological and neurological similarities amongst those who were dehydrated to those who suffered from a concussion resulted in another important conclusion.
