發燒時，身體代謝率會隨體溫上升而增加，導致氧氣消耗量與能量需求上升，進而增加心肺系統的負擔。針對發燒病人的護理目標，除了降溫外，還需節省病人的體力。透過限制活動與提供充足休息，能直接降低身體的代謝速率（Metabolic rate），是緩解生理壓力的重要護理措施。此外，保持環境舒適、適量補水也同樣重要。
Providing rest and limiting physical exertion directly lowers the client's metabolic rate and oxygen consumption, which helps alleviate the increased cardiopulmonary burden caused by fever. Conversely, exercise, caffeine, and high ambient temperatures would further increase metabolic demands and heat production.
