去年是全球有史以來最熱的一年，超過了 2023 年已經創下紀錄的平均氣溫。

本季看起來也沒有什麼好轉。

根據美國國家海洋暨大氣總署國家環境資訊中心的數據，2025 年頭幾個月已經出現了一些破紀錄的紀錄。

南加州大學 2025 年的一項研究發表在《科學進展》上，發現暴露在超過 90 華氏度（32 攝氏度）的熱指數下會加速生物老化。

研究報告的共同作者崔恩英 (Eunyoung Choi) 在新聞發布會上表示，居住在一年中有一半時間出現高溫天數（定義為熱指數為 90 華氏度或更高的日子）地區的參與者「與居住在每年高溫天數少於 10 天地區的參與者相比，生物衰老時間延長了 14 個月」。

生物老化程度越高，生病和死亡的風險也越高。

在研究中，一些老年人在暴露於極端高溫七天內就出現了生物衰老。

艾爾希爾表示，研究結果表明，現在是時候開始尋找更好的方法來減緩全球暖化了。如果我們不這樣做，老年人可能成為受高溫影響最大的人。

There's no doubt about it: It's getting hotter out there.

Scientists have discovered that extreme heat may affect how we age.

Last year was the hottest on record for the entire planet, topping 2023’s already record-setting average temperature.

This season isn’t looking much better.

The first months of 2025 have already included some record breakers, according to the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information.

Published in Science Advances, a 2025 study from the University of Southern California discovered that being exposed to a heat index over 90 degrees Fahrenheit (32 degrees Celsius) can accelerate biological aging.

Study participants who lived in places where heat days – defined as days with a heat index of 90 degrees or hotter – occur half the year “experienced up to 14 months of additional biological aging compared to those living in areas with fewer than 10 heat days per year,” co-author Eunyoung Choi said in a news release.

Higher biological aging is associated with higher risks of disease and mortality.

In the study, some older adults were biologically aged by extreme heat within seven days of exposure.

According to Ailshire, the results show it’s time to start finding better ways to cool off global warming. If we don’t, older adults may suffer from the heat the most.
