Question
When one gets "used to" a cold pool what really happens? Like does his internal body temperature actually drop? Basically how does it work?Thanks! Join or Log In to answer.
The relative importance of skin vs. core temperature for stimulating cold acclimation (CA) was examined by 5 wk of daily 1-h water immersions (20°C) in resting (RG) and exercising (EG) subjects.

Thanks all

Rectal temperature fell (0.8°C; P < 0.05) during immersion only in RG. Skin temperature fell (P < 0.05) similarly in both groups.

Physiological responses during cold-air exposure (90 min, 5°C) were assessed before and after CA. Body temperatures and metabolic heat production were similar in both groups with no change due to CA

Skin temperature reduction alone may be a sufficient stimulus during CA for increased vasoconstrictor response, but core temperature reduction appears necessary to enhance sympathetic activation during cold exposure

In extremely cold water, the body's maximal rate of shivering heat production is exceeded by the rate of heat loss.
