Analytical expressions for estimating endurance time and glove thermal resistance related to human finger in cold conditions.Frostbite is considered the severest form of cold injury and can lead to necrosis and loss of peripheral appendages.  According to the previous work which applied a 3-D thermal model for human finger to analyze cold stress, in this study, an expression is presented for endurance time in cold conditions to prevent cold injury.  A formula is also recommended to select a proper glove with specific thermal resistance based on the ambient situation and cold exposure time.  Furthermore, the effect of different parameters such as glove thermal resistance and ambient temperature is investigated analytically.
