| 目的观察常温、高温、高温高湿环境下晕动病发病的差异，探讨高温、高湿环境对晕动病发病的影响。方法某大学459名男性学员，18~23岁，体检和体能测试均合格，分别暴露于常温(20℃)、高温(38℃)及高温高湿(38℃/80%湿度)环境下，以科里奥利(Coriolis)加速度转椅试验诱发晕动病，采用格瑞比尔(Graybiel)法评定晕动病程度。结果常温、高温、高温高湿环境下受试者晕动病发病率分别为47.93%、68.94%、100%，格瑞比尔评分分别为2.07±3.12、6.06±5.45、11.87±3.42，高温高湿组显著高于高温组和常温组，差异具有统计学意义(χ2=651.84, P＜0.000 1)；3种条件下，受试者晕动病发病等级差异亦有统计学意义(χ2=644.73，P＜0.000 1)。结论高温高湿环境更容易诱导受试者产生晕动病，并可加重晕动病的症状。 |

| Abstract: |
| ObjectiveTo observe the changes of motion sickness incidences under normal temperature (NT), high environmental temperature(HT), and high environmental temperature/humidity (HTHH), so as to study the influence of high environmental temperature/humidity on the onset of motion sickness. MethodsA total of 459 male students in a university, aged 18-23 years and with normal physical condition/ability, were subjected for Coriolis acceleration test under the condition of 20℃/55%RH (NT), 38℃/55%RH (HT), and 38℃/80%RH (HTHH); then the motion sickness severity was evaluated using Graybiel scale. ResultsThe motion sickness incidences of NT, HT, and HTHH groups were 47.93%, 68.94%, and 100%, and Graybiel scores were (2.07±3.12), (6.06±5.45) and (11.87±3.42), respectively, with the latter significantly higher than those of the former two for Graybiel scores (P＜0.000 1). The severity scales of motion sickness were also significantly different between the three groups (P＜0.000 1).ConclusionHigh environmental temperature and humidity can accelerate the onset of motion sickness and aggravate the symptoms of motion sickness. |
