发烧人体体温一旦超过37℃,就属于发烧。其实,发烧是人体对病原体的抵抗手段。当病原体侵入人体时,人体的免疫细胞便群起应战,其分泌的物质作用于体温调节中枢,使人体温升高。令人称奇的是,体温越升高,免疫细胞的作战能力便越强。同时,高体温还会使血液中的铁离子浓度减少,从而 Fever body temperature once over 37 ℃, it belongs to a fever. In fact, fever is the body’s resistance to pathogens. When the pathogen invades the human body, the immune cells of the human body will fight together, and the secreted substances act on the body temperature regulating center, causing the body temperature to rise. Surprisingly, the higher the body temperature, the more immune cell combat capability. At the same time, high body temperature will also reduce the concentration of iron ions in the blood, thus
