一项有关科学进步的研究发现,产前接触炎热潮湿条件比光是热量更会危害儿童生长,南亚尤其如此。 Prenatal exposure to hot, humid conditions harms child growth more than heat alone, especially in South Asia, a study in Science Advances finds. 高湿度降低了身体的冷却能力,使热应力恶化,同时热和湿度加在一起对儿童身高的负面影响高达4倍。 High humidity worsens heat stress by reducing the body’s ability to cool, with combined heat and humidity having up to four times the negative impact on child height-for-age. 研究人员利用湿球地球温度数据，发现早孕期和第三孕期暴露导致年龄身高下降13%，仅热则为1%，凸显了脆弱地区气候知情公共卫生措施的必要性。 Using wet-bulb globe temperature data, researchers linked exposure during early and third trimesters to a 13% reduction in height-for-age—compared to 1% for heat alone—highlighting the need for climate-informed public health measures in vulnerable regions.
