下列哪位病人發展為高溫症（Hyperthermia）的風險最高？

高齡者體溫調節中樞較不敏感，且排汗能力降低，在悶熱環境下無法有效散熱。年輕人（B）雖運動量大，但調適能力較強；普通感冒（A）引起的是發燒（fever），非環境引起的高溫症；物理治療（D）通常會有監控。

Older adults have a less sensitive thermoregulatory center and reduced sweating capacity, making them unable to effectively dissipate heat in hot environments. Young athletes (B) are exposed to high exertion but generally have stronger compensatory mechanisms; the common cold (A) produces fever (an inflammatory response to infection) rather than environmental hyperthermia; and physical therapy (D) is typically supervised.

美國非常重視居家環境的評估，台灣則常見由家人協助照護，護理師需特別教導家屬如何觀察老人的水分與環境溫度。
