Resumen
El texto original del estudio, en el idioma en que se publicó.
Purpose
Exposure to cold temperatures decreases finger temperature (Tfing) and dexterity. Decreased manual function and dexterity can be serious safety risks, especially in tasks that require fine motor movements that must be performed outdoors. The aim of this study was to determine whether hand heating with a minimal power requirement (14.8 W) results in a smaller reduction in Tfing and manual dexterity performance during mild cold exposure compared to a non-heated control condition.
Methods
In a randomized crossover design, twenty-two healthy participants were exposed to a moderately cold environment (5 ºC) for 90 min. One condition had no intervention (CON), while the other had the palmar and dorsal hands heated (HEAT) by using electric heating films. Tfing and cutaneous vascular conductance (CVC) were continuously monitored using laser Doppler flowmetry. Manual dexterity performance and cognitive function were assessed by the Grooved Pegboard Test (GPT) and Stroop Color-Word (SCW) test, respectively, during the baseline period and every 30 min during the cold exposure.
Results
After the cold exposure, Tfing was higher in HEAT relative to CON (CON 9.8 vs. HEAT 13.7 ºC, p 0.05 for all). Cognitive function was similar between two conditions (p > 0.05 for all).
Conclusion
The proposed hand heating method offers a practical means of heating fingers to maintain dexterity throughout prolonged cold exposure.
