“…2016). In line with these studies, we found that for the entire Brazilian population, the youth and the elderly ≥80 years old had higher heat susceptibility than adults below age 80 did, possibly due to immature or impaired physiological systems against heat exposure (Committee on Sports Medicine Fitness 2000; Landrigan and Garg 2005). Our analyses indicated that the heat–hospitalization association and the associated attributable fraction were lowest for individuals at or around retirement age (50–79 y).…”

Background: Limited evidence is available regarding the association between heat exposure and morbidity in Brazil and how the effect of heat exposure on health outcomes may change over time. Objectives: This study sought to quantify the geographic, demographic and temporal variations in the heat–hospitalization association in Brazil from 2000–2015. Methods: Data on hospitalization and meteorological conditions were collected from 1,814 cities during the 2000–2015 hot seasons. Quasi-Poisson regression with constrained lag model was applied to examine city-specific estimates, which were then pooled at the regional and national levels using random-effect meta-analyses. Stratified analyses were performed by sex, 10 age groups, and 11 cause categories. Meta-regression was used to examine the temporal change in estimates of heat effect from 2000 to 2015. Results: For every 5°C increase in daily mean temperature during the 2000–2015 hot seasons, the estimated risk of hospitalization over lag 0–7 d rose by 4.0% [95% confidence interval (CI): 3.7%, 4.3%] nationwide. Estimated 6.2% [95% empirical CI (eCI): 3.3%, 9.1%] of hospitalizations were attributable to heat exposure, equating to 132 cases (95% eCI: 69%, 192%) per 100,000 residents. The attributable rate was greatest in children and was highest for hospitalizations due to infectious and parasitic diseases. Women of reproductive age and those had higher heat burden than men. The attributable burden was greatest for cities in the central west and the inland of the northeast; lowest in the north and eastern coast. Over the 16-y period, the estimated heat effects declined insignificantly at the national level. Conclusions: In Brazil’s hot seasons, 6% of hospitalizations were estimated to be attributed to heat exposure. As there was no evidence indicating that thermal adaptation had occurred at the national level, the burden of hospitalization associated with heat exposure in Brazil is likely to increase in the context of global warming. https://doi.org/10.1289/EHP3889

“…We did not find differences in water intake by physical activity levels, in contrast with the findings of Jomaa et al in Lebanese children aged 4–13 [21]. This finding is concerning as adequate hydration in children is critical, especially when exercising in a hot climate [50].…”

There are limited studies examining water consumption among individuals in hot climates. We assessed the daily total water intake from plain water, other beverages, and food in a nationally representative sample of children and adolescents aged 6–18 years in the United Arab Emirates. Total water intake was compared against the recommendations of the Institute of Medicine and the European Food Safety Authority. Sociodemographic information, 24 h dietary recall, physical activity levels, and anthropometric data were collected from 527 participants. The mean ± SE of total water intake was 1778.4 ± 33.8 mL/day. Plain drinking water was the largest contributor to total water intake (51.6%), followed by food (27.3%). Sugar-sweetened beverages constituted 13.9% of water intake. The proportion of participants who met the Institute of Medicine recommendations ranged from 15% (males aged 14–18) to 25% (children aged 6–8). The proportion of participants who met the European Food Safety Authority recommendations ranged from 31% (females aged 14–18) to 36% (males aged 14–18). The water-to-energy ratio was 1.0–1.15 L/1000 kcal, meeting recommendations. The majority of participants failed to meet water intake recommendations, highlighting the need for targeted interventions to promote increased water consumption among children and adolescents.

Since 1950, average land temperatures in Australia have risen by 0.9°C. 1 A decline in rainfall has been observed for much of eastern and southwestern Australia, whereas northwestern Australia has experienced wetter summers. 1 Globally, the trend of climatic variability is similar. 2 The process will continue with a projected average global temperature increase of 1.8 to 4.0°C (average 3°C) by 2100 depending on actions taken to limit greenhouse gas (GHG) emissions and scenarios for future development. 2 Rainfall is likely to become more variable and there will be more extreme weather with storms, floods and droughts. 2 By 2030 the average temperature in Australia
