目的 调查分析部分东北三省居民迁居海南省初期的中暑先兆率及影响因素，供今后迁入热带环境的居民和派遣至热带海域的海军官兵预防中暑和中暑先兆提供参考。 方法 制作中暑先兆率和影响因素调查表，通过电话或网络通信方式对2010-2020年迁居海南省的202名东北三省居民、57名北方非东北居民、92名海南本地居民进行调查，并分析中暑先兆发病原因和影响因素。 结果 东北三省居民的中暑先兆率为11.4%，其中迁入前规律锻炼者（每周锻炼3次或3次以上）中暑先兆率低于未规律锻炼者（P<0.05），有饮凉茶习惯者（每周饮凉茶3次或3次以上）中暑先兆率低于无饮凉茶习惯者（P<0.05）。 结论 坚持规律锻炼和饮凉茶有利于迁入热带地区的居民和派遣至热带海域的海军官兵预防中暑和中暑先兆。 Objective To investigate and analyze the incidence of premonitory heatstroke and influencing factors of migrants from northeast China to Hainan province，so as to provide reference to prevent premonitory heatstroke and heatstroke among inhabitants migrating to tropical areas and naval officers and sailors dispatched to tropical seas in the future. Methods A survey on the incidence of premonitory heatstroke and influencing factors was made among 202 residents from the three provinces in northeast China and 57 from northern China other than the three provinces who moved to Hainan province from 2010 to 2020，and 92 residents of Hainan Province origin were investigated by telephone or Internet，and the causes and influencing factors of premonitory heatstroke were analyzed. Results The incidence of premonitory heatstroke of migrants from the three northeast provinces was 11.4%. Among the migrants，those who exercised regularly before migration（3 or more times per week）had lower incidence than those who didn’t（P<0.05），those who had the habit of drinking herbal tea（3 or more times per week）had lower incidence than those who didn’t（P<0.05）. Conclusion Doing exercise regularly and drinking herbal tea can prevent premonitory heatstroke and heatstroke in the people migrating to tropical areas and naval officers and sailors dispatched to tropical seas.
