Toe temperatures during arctic training.
The surface toe temperature of 10 subjects was monitored in the field in Arctic Norway (minimum air temperature -27 degrees C). The lowest skin temperature recorded was 1.9 degrees C. The mean estimated time for the toe temperature to cool from 25 degrees C to 5 degrees C was 109 minutes (SD, 10.2) at an ambient temperature of -21 degrees C. One subject experienced a toe temperature below 5 degrees C for 2.9 hours during a 27-hour period. Surprisingly none of the subjects demonstrated clinical signs of cold injury, but this does not mean that this exposure was without risk. Cold sensitization could have occurred.
