| Abstract | The thermal responses to environmental conditions consisting of varying wind speeds and wave heights were measured using volunteers at the National Research Council of Canada’s Institute for Ocean Technology. Twelve healthy males performed three, three hour immersions in Calm Water, Weather 1 (wind speed = 3.5 m·s-1, max wave height = 0.34m), and Weather 2 (wind speed = 4.6 m·s-1, max wave height = 0.64m) in a commercially available immersion suit. The two weather conditions produced significantly greater heat flow in the participants compared to the Calm condition. There was no significant difference in deep body temperature across all immersion conditions; however Weather 2 produced a significantly greater drop in mean body temperature (-1.51°C) compared to the Calm condition (-1.10°C). Small changes in cutaneous blood flow and increased metabolic heat production allowed the participants to successfully thermoregulate in the environmental conditions tested. It is recommended that future testing of humans in immersion suits incorporate the increased heat loss due to wind and waves. |
