Objective To 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.Methods A 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.Results The 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 (P0.000 1).The severity scales of motion sickness were also significantly different between the three groups (P0.000 1).Conclusion High environmental temperature and humidity can accelerate the onset of motion sickness and aggravate the symptoms of motion sickness. |
