Effect of Environmental Temperature on Sweat Onset During Motion Sickness,
Abstract
Since the sweat response is observed as part of some motion-sickness- rating procedures, it is useful to know if other variables such as environmental temperature can affect the response during vestibular stimulation on several occasions. On each occasion the run was carried out with a different environmental temperature. At a relatively high temperature the thermal stress caused a sweat response, and no vestibular stimulation was required. With lower environmental temperatures, a longer period of vestibular stimulation was required to evoke the sweat response. At a relatively low temperature no sweating was observed despite continuous vestibular stimulation and the development of severe nausea. The results indicate that environmental temperature can affect the sweat response during motion sickness and suggest the possible hazard of excessive fluid and electrolyte loss when both vestibular and thermal stress are present. By proper selection of environmental temperature, sweating can be induced before the onset of nausea. In this situation the sweat response could serve as a useful predictor of motion-sickness onset in the administration of adaption schedules and in monitoring persons in the space- flight environment.
