Abstract Objective Spectral analyses of laser‐Doppler flowmetry measures enable a simple and non‐invasive method to investigate mechanisms regulating skin blood flow. We assessed within‐day day‐to‐day variability cutaneous spectral analyses. Methods Eleven young, healthy males were tested twice in three identical sessions, with 19 24 days between visits, for total six tests. Wavelet data analyzed at rest, response local heating 42 44°C, during 5‐minutes PORH. did this frequency bands commonly associated physiological functions. To assess reliability, we calculated CV ICC scores. Results At mean the wavelet ranged from 21% 24% scores 0.67 0.91. During heating, 17% 22% 0.71 0.95. For peak PORH, 14% 23% range was 0.88 0.97. area under curve 12% 0.81 0.92. Conclusions These indicate good‐to‐excellent reliability young males.
