Two immersion suit studies, one dry and the other with 500 mL of water underneath the suit, were conducted in cold water with 10-12 males in each to test body heat loss under three environmental conditions: calm, as mandated for immersion suit certification, and two combinations of wind plus waves to simulate conditions typically found offshore. In both studies mean skin heat loss was higher in wind and waves vs. calm; deep body temperature and oxygen consumption were not different. Mean survival time predictions exceeded 36 h for all conditions in the first study but were markedly less in the second in both calm and wind and waves.Immersion suit protection and consequential predicted survival times under realistic environmental conditions and with leakage are reduced relative to calm conditions.

Correction factors for assessing immersion suits under harsh conditions

“…These discrepancies were the justification for our recent experimental investigation of the effects of wind and waves on predicted survival times (Power et al, 2015). We confirmed that immersions in wind and waves will significantly increase heat loss compared to calm water, and that predicted survival time is reduced as a consequence, which is exacerbated as water temperature decreases.…”

Cold Water Swimming—Benefits and Risks: A Narrative Review

“…Heat loss can occur by conduction of heat from the skin to the cold water around the body. It has been shown that mean skin heat loss was higher in wind and waves [115].…”

Lost at sea: the medicine, physiology and psychology of prolonged immersion

“…Deep body temperature regulation is a balancing act between inputs that cool the body (for example cold water, wind and waves 19 ) and those that can increase heat production (exercise and shivering) or maintain heat storage (insulation from clothing, unperfused muscle and body fat). The temperature and duration of immersion endured in 17°C waters is likely to result in a fall in deep body temperature (from approximately 37°C) and may result in hypothermia (a deep body temperature below 35°C, immersion phase three 12 ).…”
