“…Despite several anecdotal accounts of a possible MSrelated decrease in core temperature (Crampton 1955;Golden 1973;Graybiel 1969;Hemingway 1944;Hesse 1874), the likelihood of MS interfering with temperature regulation has received little attention. Hesse (1874) was one of the Wrst to report a decrease in body temperature in individuals suVering from MS.…”

Motion sickness increases the risk of accidental hypothermia

Motion sickness (MS) has been found to increase body-core cooling during immersion in 28 degrees C water, an effect ascribed to attenuation of the cold-induced peripheral vasoconstriction (Mekjavic et al. in J Physiol 535(2):619-623, 2001). The present study tested the hypothesis that a more profound cold stimulus would override the MS effect on peripheral vasoconstriction and hence on the core cooling rate. Eleven healthy subjects underwent two separate head-out immersions in 15 degrees C water. In the control trial (CN), subjects were immersed after baseline measurements. In the MS-trial, subjects were rendered motion sick prior to immersion, by using a rotating chair in combination with a regimen of standardized head movements. During immersion in the MS-trial, subjects were exposed to an optokinetic stimulus (rotating drum). At 5-min intervals subjects rated their temperature perception, thermal comfort and MS discomfort. During immersion mean skin temperature, rectal temperature, the difference in temperature between the non-immersed right forearm and 3rd finger of the right hand (DeltaTff), oxygen uptake and heart rate were recorded. In the MS-trial, rectal temperature decreased substantially faster (33%, P < 0.01). Also, the DeltaTff response, an index of peripheral vasomotor tone, as well as the oxygen uptake, indicative of the shivering response, were significantly attenuated (P < 0.01 and P < 0.001, respectively) by MS. Thus, MS may predispose individuals to hypothermia by enhancing heat loss and attenuating heat production. This might have significant implications for survival in maritime accidents.

“…Four distinct experimental conditions were chosen which varied with respect to the presence of additional visual cues that were superimposed on the screen: two conditions included earthstationary visual cues (Fixation Cross and a Fixed Horizon), one condition included a visual cue that was congruent with the camera's random motion (Moving Horizon), and one condition acted as control with no additional visual cues (No Visual Cues). Apart from self-reported VIMS scores, we measured heart-rate and eye-movements, which have been linked to the occurrence of VIMS in previous studies (Crampton, 1955;Cowings et al, 1986;Stout et al, 1995;Holmes and Griffin, 2001), considering that the majority of VIMS symptoms is related to an increase in sympathetic activity and a decrease in parasympathetic activity (Hu et al, 1991;Doweck et al, 1997;Holmes and Griffin, 2001). Although a strong relationship between heart-rate/heartrate variability and VIMS could not be established in the past (Mullen et al, 1998), we added these measures to gather further insights into the physiological changes associated with VIMS.…”

Visually induced motion sickness is an unpleasant but common side-effect of many simulations and VR-applications. We investigated whether an earth-fixed reference frame provided in the simulation is able to reduce motion sickness. To do so, we created a moving starfield that did not contain any indicators of the spatial orientation of the observer. As the observer was simulated to move through the randomly oscillating starfield, a time-to-contact task had to be carried out. Two colored stars on collision course with each other had to be spotted, then they disappeared and the time of their collision had to be judged. Eye-movements, task performance, and motion sickness were recorded. This condition without visual reference to the observer's upright was supplemented with three conditions containing either an earth-fixed fixation cross, an earth-fixed horizon line, or a line that was yoked to the head. Results show that only the earth-fixed horizon was able to significantly reduce visually induced motion sickness. Thus, a mere earth-stationary anchor does not suffice, a clear indication of earth horizontal seems necessary to reap a modest benefit.

“…Existing human data on the link between motion sickness and cutaneous vascular tone are controversial, limited and inconclusive. The first study where skin blood flow was assessed during MS provocation, reported a 50-60% fall in finger pulse volume indicative of vasoconstriction 7 . Several other early studies demonstrated that MS is associated with an increase in forearm blood flow 35,36 .…”

Principal symptoms of motion sickness in humans include facial pallor, nausea and vomiting, and sweating. It is less known that motion sickness also affects thermoregulation, and the purpose of this review is to present and discuss existing data related to this subject. Hypothermia during seasickness was firstly noted nearly 150 years ago, but detailed studies of this phenomenon were conducted only during the last 2 decades. Motion sickness-induced hypothermia is philogenetically quite broadly expressed as besides humans, it has been reported in rats, musk shrews and mice. Evidence from human and animal experiments indicates that the physiological mechanisms responsible for the motion sickness-induced hypothermia include cutaneous vasodilation and sweating (leading to an increase of heat loss) and reduced thermogenesis. Together, these results suggest that motion sickness triggers highly coordinated physiological response aiming to reduce body temperature. Finally, we describe potential adaptive role of this response, and describe the benefits of using it as an objective measure of motion sickness-induced nausea.
