Adequate fluid consumption is central to human survival. Previous literature suggests that there some misconceptions regarding hydration and fluid balance in some populations. Available data also show that the role of thirst sensations in maintaining fluid balance in different settings is also equivocal. Therefore, this thesis aimed to examine the perception of hydration, thirst and fluid intake in freeliving populations, to examine the feasibility of thirst as a marker of hydration status and to investigate the effect of thirst related sensations on fluid balance in resting and exercising individuals under different ambient temperatures. The findings in this thesis (Chapter 3) show that individuals who work within the fitness industry demonstrated substantial knowledge about drinking practices, hydration status and health consequences of water consumption, but lack understanding on the type of beverages that adequately hydrate the body. Further, thirst perception and mood states did not affect (P>0.05) the fluid intake in free living individuals (Chapter 4) and resting individuals under cool and warm exposure (Chapter 6), but some other factors such as subjective feelings of mouth dryness and the extent of hydration status might influence the fluid intake behaviour in these populations. In addition, following ingestion of flavoured carbohydrate drinks, thirst sensations was rated lower over time (P<0.05) during exercise in the cool, but was higher over time in the warm temperature (Chapter 7). Moreover, subjective feelings related to dehydration such as mouth dryness, thirst perception, desire to drink (water pleasantness) and hunger rating could be used as index of hydration status to signify at least a 1% body mass loss due to food and fluid restriction in resting individuals (Chapter 5). In conclusion, the findings in this thesis provide some new insight with respect to hydration, thirst and fluid balance in different populations under different settings. Nevertheless, some inconclusive findings regarding the role of thirst related sensations in fluid balance require further investigations.

The main objective of this work is to understand the subjective sense which this caretaker (father or mother) develops concerning the buccal health of their child with the Down´s Syndrome and general health. The child Down´s Syndrome is seen within their biological, odontological and psychological limits. To understand the human development of such a person with the Down´s Syndrome, the dissertation applies to Vygotsky s Human Development Theory. For this author, the human development of a handicap child follows the same principles of a normal child, the only thing about the indirect ways. On the other hand, the caretaker will be analyzed while the senses of buccal health are developed with their interaction with the handicap child, together with a professional team, their family and society in general. The author who will be employed to accomplish such analysis will be Gonzalez Rey, who, for twenty years, has been constructing the subjective theory within the parameters of the Vygotskian historic cultural school, and which has one of its main pillar the subjective sense. The qualitative methodology has been used for such study, while a whole set of epistemological rules defend the constructive interpretative knowledge character. The instrument which was used to collect the data was the conversational system, of which,the thematic dialog is accomplished as a complement. The main conclusion of the work is that the caretaker of a child with the Down Syndrome, living with their child s syndrome, transformed or is transforming, their subjective feelings as to the buccal health to the child s general health. / Esta dissertação tem como objeto de estudo o cuidador (pai ou mãe) de crianças com Síndrome de Down. O objetivo principal do trabalho é compreender os sentidos subjetivos que este cuidador (pai ou mãe) gera em relação à saúde bucal de seu filho com Síndrome de Down e à saúde em geral. A criança com Síndrome de Down é vista em seus limites biológicos, odontológicos e psicológicos. Para compreender o desenvolvimento humano de tal sujeito com Síndrome de Down, a dissertação recorre à Teoria do Desenvolvimento Humano de Vygotski. Para este autor o desenvolvimento humano de uma criança especial segue os mesmos princípios que o de uma criança comum, só que a criança especial atinge seu desenvolvimento por caminhos indiretos. Por outro lado, o cuidador será analisado enquanto gera sentidos da saúde bucal em sua interação com a criança especial, com a equipe profissional, com sua família e sociedade em geral. O autor usado para se concretizar tal análise será González Rey, que há vinte anos, esta construindo a teoria da subjetividade dentro dos parâmetros da escola históricocultural vygotskiana, e que tem como um de seus pilares o sentido subjetivo. A metodologia usada para tal tipo de estudo é a qualitativa, enquanto um conjunto de regras epistemológicas que defende o caráter construtivo interpretativo do conhecimento. O instrumento utilizado para coleta de dados foi o dos sistemas conversacionais, nos quais o diálogo temático é realizado como complemento. A principal conclusão do trabalho é que a cuidadora da criança com Síndrome de Down, na vivência com a síndrome de seu filho, transformou e está transformando, seus sentidos subjetivos tanto da saúde bucal, quanto da saúde geral de sua criança.
