**预计亚洲和非洲地区影响最为严重**
据中新网北京5月15日电（记者 孙自法）最新发表在施普林格·自然旗下学术期刊《自然-通讯》上的一篇健康研究论文指出，随着全球气候变化的影响日益加剧，到2050年，全球预计将有高达2.46亿老年人口生活在危险的高温环境中。这一数据凸显了气候变化对老年人健康构成的潜在威胁，尤其是亚洲和非洲地区的老年人，他们面临的风险最为严重。
该研究分析了全球不同地区老年人面临的高温风险，并考虑了人口老龄化、城市化以及全球气候变暖趋势等多种因素。研究发现，如果不采取有效措施，到2050年，亚洲将拥有超过1.2亿老年人生活在高温环境中，非洲也将达到约8200万。这两个地区的人口比例之所以如此之高，部分原因是由于目前这两个地区的高温暴露人口比例已经较高。
研究强调，高温环境对老年人健康的影响尤为明显，因为随着年龄的增长，人体调节体温的能力会下降，对热应激的敏感性也随之增加。长期暴露在高温环境中，可能导致老年人出现中暑、脱水、心脏病和认知功能下降等问题。
论文作者之一表示，这项研究结果迫切需要全球各国政府和社会各界的高度关注和行动。他们建议，通过改善老年人的居住条件、增强城市基础设施的抗热能力、提供老年人的健康教育和保护措施，以及制定相应的政策和规划，来降低高温环境对老年人的风险。
此外，研究还建议加强国际合作，分享在应对气候变化和保护老年人健康方面的成功经验。通过这些措施，可以为老年人创造一个更加安全、健康的未来环境，减轻他们因高温环境而受到的健康威胁。

### CNBC Health Study: Over 246 Million Elderly People Worldwide at Risk of High Heat Environment by 2050
**Asia and Africa Expected to Be Hardest Hit**
BEIJING, May 15 (XinhuaNet) — A new health research paper published in the Springer Nature journal “Nature Communications” warns that with the intensifying impact of global climate change, as many as 246 million elderly people around the world are expected to be living in dangerous high heat environments by 2050. This data highlights the potential threat climate change poses to the health of the elderly, with those in Asia and Africa facing the most severe risks.
The study analyzed the heat risk faced by the elderly in different global regions, taking into account factors such as population aging, urbanization, and the trend of global climate warming. It found that without effective measures, by 2050, over 120 million elderly people in Asia and about 82 million in Africa will be living in high heat environments. A significant reason for such a high proportion in these regions is the already high percentage of their populations currently exposed to high heat.
The research emphasizes that the impact of high heat environments on elderly health is particularly significant. With age, the body’s ability to regulate body temperature declines, and sensitivity to heat stress increases. Prolonged exposure to high heat can lead to heatstroke, dehydration, heart disease, and cognitive function decline in the elderly.
One of the paper’s authors said that these findings urgently require the attention and action of governments and societies worldwide. They suggest improving the living conditions of the elderly, enhancing the heat resistance of urban infrastructure, providing health education and protection measures for the elderly, and developing corresponding policies and planning to reduce the risks posed by high heat environments to the elderly.
Furthermore, the study proposes strengthening international cooperation to share successful experiences in addressing climate change and protecting elderly health. Through these measures, a safer and healthier future environment can be created for the elderly, mitigating the health threats posed by high heat environments.
