Description
Summary:The purpose to this letter to the Editor is to describe the results of pilot studies conducted to evaluate body cooling by water immersion, with and without nicotinic acid. Nicotinic acid pretreatments resulted in greater body cooling than control trials. However, cooling rates were less than can be achieved with evaporative cooling techniques. The striking feature of the nicotinic acid trials involved the magnitude of body cooling achieved in relatively temperate water (30 C). Keywords: Hypothermia, Heat stroke, Rectal temperature.
