Effect of Moderate Cold Exposure on Manual Dexterity: Assessment with Two Dexterity Tests

Abstract

Moderate cold exposure at -5°C and 5°C significantly decreased finger and hand skin temperatures. A keyboard typing test responded promptly to the decreases in the hand temperature even when the hand temperature was above the threshold temperature (20°C) for performance decrement that was defined in the previous studies. This finding could be helpful to building safety guidelines for working in cold environments.
