Genetic, acclimatizational and anthropometric factors in hand cooling among North and South Chinese

The left hands of unacclimatized North Chinese (N=16) and South Chinese (N=13) were exposed to 5 degrees C water for 30 minutes followed by a 10 minute recovery period. Significant differences independent of body composition were found between the two samples on mean 30 minute temperature during imm...

Summary:The left hands of unacclimatized North Chinese (N=16) and South Chinese (N=13) were exposed to 5 degrees C water for 30 minutes followed by a 10 minute recovery period. Significant differences independent of body composition were found between the two samples on mean 30 minute temperature during immersion, time and temperature of the onset of initial CIVD (cold-induced vasodilation) at 0.01, 0.05 and 0.10 levels respectively. The result suggests the presence of a genetic component in the cold responses of Continental Asian populations and the possibility of the presence of a clinal distribution of cold response in Asia.
