“…Scarcity of potable water adds to the woe leading to altered body hydration status. During heat wave significant mortality and morbidity occurs due to heat stress and dehydration (5). Dehydration is primarily attributed to inadequate water intake caused by dysfunction of the central nervous system mechanisms controlling thirst (5).…”

“…It is an established fact that hypohydration can lead to haemo-concentration. Reduced thirst and ingestive behavior have been reported in response to hyper-osmotic stimuli, hypovolemic stimuli and dehydration (5). Sufficient body water is required to sustain thermoregulatory function, thus losses in total body water can challenge the thermoregulatory system.…”

This study highlights the effect of extreme heat stress exposure (WBGT Index 36.24°C) on hematological variables while performing graded physical activity (sedentary, moderate and heavy). Total 30 participants were involved in the study and were randomly distributed into batches of 10 under three categories of physical activity. Volunteers performed physically strenuous work while being exposed to ambient heat stress (hot -arid conditions). White Blood Corpuscles (WBC) count in heavy work group [506 kcal/ hr energy expenditure] showed significant increase from pre to post exposure (p < 0.01). No other group showed significant change in WBC count. Haematocrit % (Hct %) was significantly increased among heavy work group (p < 0.01) whereas Red Blood Corpuscles (RBC) count and Red Blood Cell Distribution Width (RDW) showed no significant increase. Blood viscosity showed increase among moderate work group [412kcal / hr energy expenditure] (p<0.05) and heavy work group (p< 0.001). These alterations indicate that participants exposed to high ambient temperature while doing graded physical activity underwent considerable hypo-hydration (sweat loss upto 4% of body weight) which got reflected in hematological parameters. This depletion of body fluid got reflected on blood viscosity and WBC count at a stage when the condition was not subjectively perceived. Data may be beneficial to identify such hypo hydration status before the condition is manifested visibly or symptomatically.

“…Os ganhos relativos à diminuição da taxa de mortalidade e respectivo aumento da expectativa de vida, relacionam-se, ainda que discretamente, à melhoria no acesso da população aos serviços de saúde. Esse fenômeno é denominado de compressão da mortalidade que, para ser considerado uma conquista real para a população de idosos, deve atrelar-se às ações para prolongar a vida com qualidade, autonomia e capacidade funcional, retardar evolução de doenças por meio de prevenção efetiva e postergar a morte, dentro das possibilidades éticas e tecnologias em saúde (FRIES, 1980;BRASIL, 2006;VERAS, 2009;BRASIL, 2010 ROLLS; PHILLIPS, 1990;MACK et al, 1994;DAVIES et al, 1995;BEGG, 2017).…”

“…Sugere-se que a concentração menor de aldosterona nos organismos dos idosos, juntamente com as alterações tubulares renais intrínsecas, sejam os principais responsáveis pela natriurese (ROLLS; PHILLIPS, 1990;MILLER, 1997, BEGG, 2017.…”
