Is it possible to feel cold even while wearing an exposure suit in warm water?

Wearing an exposure suit in warm water is generally intended to help retain body heat and protect against environmental factors. However, it is indeed possible to feel cold even with an exposure suit. Several factors can contribute to this sensation.

One major reason is that exposure suits, particularly wetsuits, provide insulation primarily through trapped water between the suit and the skin. If the water temperature is significantly lower than body temperature, or if the suit is not fitted properly, it can allow cold water to circulate in and out, resulting in heat loss and a feeling of being cold.

Additionally, factors such as body metabolism, relative humidity, wind conditions (if in or out of the water), and individual tolerance to cold can play a significant role. Even in warm water, if someone is submerged for an extended period, their body may lose heat faster than it can replace it, prompting a sensation of cold.

In contrast, inadequate suits or exposure time could also impact comfort levels, but feeling cold in warm water while wearing an exposure suit due to other environmental factors or personal physiological responses captures the complexity of thermal regulation in diving settings.
