儿童在高温环境中面临的风险远高于成人。儿童的下丘脑发育尚未完全成熟,导致出汗能力较弱且难以感知口渴[1];同时儿童体表面积与体质量的比值远大于成人,使其吸收热量的速度更快[1]。当儿童过热时可能导致热衰竭甚至热中风,后者体温可能超过40°C,构成医疗紧急情况[1]。对5岁以下儿童而言,高温健康风险尤其严重,甚至可能增加婴儿突然死亡综合征的风险[1]。英国6月热浪期间,六分之一的婴儿生活在过热的家中[1]。
医疗专业人士建议采取多项措施保护儿童安全。NHS建议将新生儿房间温度保持在约16°C至20°C之间[1]。医学博士Jessica Mee强调,应确保儿童充足的水分摄入,鼓励他们在阴凉处休息,穿着宽松浅色服装,并密切监测热应激迹象[1]。
Children face significantly greater risks during extreme heat than adults due to their physiological vulnerabilities. [1] Their hypothalamus, which regulates body temperature, remains incompletely developed, particularly in those under five years old, limiting their ability to sweat effectively and recognize thirst. [1] Additionally, children have a higher surface-area-to-mass ratio than adults, causing their core body temperature to rise more rapidly when exposed to heat. [1]
The dangers of overheating in young people can be severe and life-threatening. [1] Heat exhaustion and heat stroke represent serious medical emergencies, with heat stroke potentially raising body temperature above 40°C. [1] Excessive heat also increases the risk of Sudden Infant Death Syndrome (SIDS) in infants. [1] Data from a June heatwave in the United Kingdom revealed that one in six babies were living in overheated homes. [1]
Health authorities provide clear guidance for protecting children during high temperatures. The NHS recommends maintaining newborn room temperatures at approximately 16°C to 20°C. [1] Dr. Jessica Mee advises parents to ensure children drink sufficient fluids, encourage rest in cool environments, dress them in loose-fitting light-colored clothing, and monitor for signs of heat stress.
