Heating a human palm during 3 minutes period causes changes in superficial skin temperature and leads to thermoregulation system response. The response time and level of flow characteristics change depend on the subject hand size and health of his vascular tree. A solution of Pennes bioheat propagation model was analyzed in order to see how much heat has to be transferred into the tissue to extort the observable reaction. The reflective PPG sensor, blood pressure monitor and Doppler probe were attached to fingers of heated palm. The changes were particularly noticed in a color of a heated skin and PPG signal and less significant in the signals of blood pressure and flow velocity. The research revealed certain agreement between assumed local blood pressure trend direction and skin heating phase. That could be a contribution to the usefulness of vascular system health determination based on short time hand heating.
