Finger Induced Auto-Thermogenesis

Heat through hand-clasping with a specific finger pose (HCFP) is a tool for eliciting innate immune system response to control the SARs-CoV-2 virus. Fifteen male subjects participate in a study in which ECG and axillary temperature are measured, with and without HCFP. The heat induction is derived from temperature slope and we studied its effect on heart rate variability (HRV) and resting metabolic rate (RMR). Compared to the normal state, the average axillary temperature slope increases by 11.5% along with a significant increase in resting metabolic rate (RMR) (p<0.05) respectively. HRV enhances through an increase in SDRR and RMSSD by 23.75 and 24.44%, respectively. The Augmented-LFHF ratio reduces significantly (p<0.001). HCFP induces body-heat mediated by parasympathetic nervous system (PSNS) dominance with minimal changes in body temperature due to thermoregulation.
