Abstract

Objectives: This article discusses heatwaves (HWs), their definitions, and increasing frequencies associated with climate change, as well as their effects on human health, especially on children and vulnerable groups. It emphasizes the need for interdisciplinary studies to better understand the effects of HWs and preventive actions to mitigate the effects caused by this phenomenon.

Data source: The data were obtained from recent studies, conducted in Brazil and abroad, on the impacts of HWs. The figures were attained with data provided by the Climate Change Knowledge Portal.

Data summary: HWs are periods of extreme heat, modulated by climate phenomena such as El Niño and the Pacific Decadal Oscillations. The frequency and intensity of HWs have increased since the 1950s, driven by climate change. HWs affect public health by increasing the risk of mortality from respiratory and cardiovascular diseases. Children are more vulnerable to problems such as fever caused by heatstroke, respiratory and kidney infections, as well as risks such as sudden infant death syndrome. Almost half of the HW episodes observed in South America in this century occurred in Brazil, mainly in socioeconomically vulnerable regions.

Conclusions: The increase in the number of HWs is a direct consequence of climate change and has severe impacts on public health and biodiversity. Vulnerable groups suffer more from these phenomena, and social inequalities aggravate the problems. It is essential to promote awareness, implement effective public policies and encourage interdisciplinary research to mitigate the effects of HWs on society.

气候变化时期的热浪、生物多样性和健康。
目的:本文讨论了热浪(HWs)、热浪的定义、与气候变化相关的日益频繁的热浪,以及热浪对人类健康的影响,尤其是对儿童和弱势群体的影响。文章强调有必要开展跨学科研究,以更好地了解热浪的影响,并采取预防措施减轻这一现象造成的影响:数据来源:这些数据来自最近在巴西和国外进行的有关有害健康物质影响的研究。数据摘要:HWs 是受厄尔尼诺和太平洋十年涛动等气候现象影响的极端炎热时期。自 20 世纪 50 年代以来,受气候变化的影响,HWs 的频率和强度都有所增加。高温天气会增加呼吸道和心血管疾病的死亡风险,从而影响公众健康。儿童更容易出现中暑发烧、呼吸道和肾脏感染等问题,以及婴儿猝死综合症等风险。本世纪在南美洲观察到的高温中暑事件几乎有一半发生在巴西,主要集中在社会经济脆弱的地区:结论:HWs 数量的增加是气候变化的直接后果,对公共卫生和生物多样性造成了严重影响。弱势群体受这些现象的影响更大,社会不平等加剧了这些问题。必须提高认识,实施有效的公共政策,鼓励跨学科研究,以减轻 HWs 对社会的影响。
