Extreme heat waves have recently affected Europe and are now impacting the central and eastern United States, making medical and systemic precautions necessary.

極端熱浪近期影響了歐洲，目前正影響美國中西部與東部，因此有必要採取醫療與系統性的預防措施。

The current weather situation is caused by a 'heat dome' over the eastern United States. According to the National Oceanic and Atmospheric Administration (NOAA) and the National Weather Service (NWS), heat levels could reach 115 degrees Fahrenheit. This follows a period of record-breaking temperatures in several European countries, such as Germany, France, and the UK. These simultaneous events show a broader trend of heat waves becoming more frequent and intense.

目前的氣候狀況是由美國東部上空的「熱穹頂」所引起。根據美國國家海洋暨大氣管理局 (NOAA) 與國家氣象局 (NWS) 的數據，氣溫可能會達到華氏 115 度。在此之前，德國、法國與英國等多個歐洲國家已經歷了一段打破紀錄的高溫期。這些同時發生的事件顯示出一個更廣泛的趨勢，即熱浪正變得更加頻繁且劇烈。

From a medical perspective, the human body tries to cool itself down through sweating and increasing blood flow to the skin when temperatures rise above 23 degrees Celsius. However, Dr. Claudia Traidl-Hoffmann emphasized that the environment is changing too quickly for humans to adapt biologically, a process that would normally take centuries. Consequently, if these cooling systems fail, it can lead to serious health problems, including heart distress, lung inflammation, or organ failure, especially when the body's core temperature reaches 42 degrees Celsius.

從醫學角度來看，當氣溫升至攝氏 23 度以上時，人體會嘗試透過出汗與增加皮膚血流量來降低體溫。然而，Claudia Traidl-Hoffmann 醫師強調，環境變遷速度過快，導致人類在生物學上無法適應，而這個過程通常需要數個世紀。因此，如果這些冷卻系統失效，可能會導致嚴重的健康問題，包括心臟衰竭、肺部發炎或器官衰竭，尤其是當身體核心溫度達到 42 度時。

Certain groups are more vulnerable than others based on age and health. The CDC and NHS identify infants, the elderly, pregnant women, and people with chronic illnesses—such as kidney disease or diabetes—as high-risk. Furthermore, the UCLA Heat Lab noted that high humidity and still air make these heat-related illnesses worse. To reduce these risks, doctors recommend drinking plenty of water in advance, wearing lightweight clothing, and managing chronic health conditions before the heat season begins.

根據年齡與健康狀況，某些族群比其他人更脆弱。美國疾病管制與預防中心 (CDC) 與英國國民醫療服務體系 (NHS) 將嬰幼兒、長者、孕婦以及患有慢性病（如腎臟病或糖尿病）的人定義為高風險群。此外，UCLA 熱能實驗室指出，高濕度與無風環境會加劇這些熱相關疾病。為了降低風險，醫師建議在酷暑季節開始前，預先多喝水、穿著輕便衣物並管理好慢性健康狀況。

The United States remains under extreme heat warnings, and high temperatures are expected to continue through the Independence Day holiday, despite some forecasts of rain.

美國目前仍處於極端高溫警告中，儘管部分預報顯示將有雨，但預計高溫將持續至獨立日假期。
