The number of computer users has progressively grown over the last three decades. The modern world is unimaginable without computers and digital technologies. The preliminary observational findings indicate the significant effect of the duration and ergonomics of computer mouse work on the development of hand hypothermia. Vertical computer mouse work preserved more stable and higher temperatures of the wrist (>30 ☌), while continuous use of a horizontal mouse for more than two hours caused an extremely low temperature (<28 ☌) in distal parts of the hand.
#HOLDING A MOUSE IN CLOSED HANDS SKIN#
Hand skin temperature decreased markedly after one hour of continuous computer mouse work. The study revealed a significantly strong negative correlation between the temperature of the dorsal surface of the wrist and time spent working with a computer mouse. Three different ergonomic computer mouse setups were tested on three different days (horizontal computer mouse without mouse pad horizontal computer mouse with mouse pad and padded wrist support vertical computer mouse without mouse pad).
Digital infrared imaging of the right forearm and wrist was performed during three hours of continuous computer work (measured at the start and every 15 minutes thereafter) in a laboratory with controlled ambient conditions. The aim of our study was to evaluate the dynamics of skin surface temperature in the hand during prolonged computer mouse work under different ergonomic setups. Computer work is characterized by sedentary static workload with low-intensity energy metabolism.
