Working in Cold Temperatures

The effects of cold exposure depend on the type of physical activity, type of clothing, individual characteristics such as gender, age and health, and exposure from climatic conditions such as temperature and wind. The contributing factors of cold exposure can result in effects such as discomfort, reduced physical performance, impaired cognition, cold injuries and cold associated injuries. Furthermore, reduced performance can lead to reduced concentration and may increase the risk of accidents and injuries. Exposure to cold impairs cognition, such as problem-solving and decision-making, and may adversely affect physical functions, concentration and vigilance, which can lead to longer response time and increased amount of errors. To avoid critical situations, it is imperative to decrease cold exposure as it may affect cognitive performance and influence safety.

Due to the cold climate and risks involved working in it, it has been a demand for equipment to monitor workers in cold climate.


Effects of Cold

The human responses in cold environment are dependent on the cold, wind, humidity, winter darkness, and physical isolation, additionally these factors have a profound influence on human performance.

Low tissue temperature impairs nerve-motor function, and several studies have proved that there is a clear relationship between skin temperature and manual performance, presented in figure below
