1. 1. Ten male students remained in a severely cold room (-25°C) for 20 min. thereafter, they transferred in a warm room (25°C) for 20 min.
2. 2. This pattern was repeated three times, total cold exposure time amounting to 60 min.
3. 3. In the warm room, the subjects removed their cold-protective jackets, or wore them continously.
4. 4. Rectal temperature, skin temperatures, manual performance and thermal comfort were measured during the experiment.
5. 5. Removing cold-protective jackets after severe cold exposure increased peripheral skin temperatures and reduced the discomfort in the warm room.
6. 6. However, these results were accompanied by a greater decrease in rectal temperature and manual performance.
7. 7. It is recommended that workers continue to wear cold-protective clothing in the warm areas outside of the cold storage to prevent decreases in deep body temperature and work efficiency caused by repated cold exposures.
