Skin blood vessels will dilate and constrict with changes in peripheral temperature. Cold-induced vasodilation (CIVD) in the finger tips occurs after the onset of local cold exposure in the extremities, and CIVD is followed by a phase of vasoconstriction. However, the mechanism of CIVD is still not clear. This paper introduces one example of multi-measurement of CIVD. Wavelet analysis of blood flow has previously revealedvarious peaks in the power spectrum corresponding to specific origins. Thus our group used wavelet transform analysis to identify factors affecting CIVD, and also investigated endothelial nitric oxide synthase activation under cold conditions.
