Skin blood perfusion and oxygenation depends upon cardiovascular, hormonal and circulatory health in humans and provides socio-sexual signals of underlying physiology, dominance and reproductive status in some primates. We allowed participants to manipulate colour calibrated facial photographs along empirically-measured oxygenated and deoxygenated blood colour axes both separately and simultaneously, to optimise healthy appearance. Participants increased skin blood colour, particularly oxygenated, above basal levels to optimise healthy appearance. We show, therefore, that skin blood perfusion and oxygenation influence perceived health in a way that may be important to mate choice.
皮肤的血液灌注和氧合作用取决于人类的心血管、激素和循环系统健康状况，并在某些灵长类动物中提供潜在生理机能、优势地位和生殖状态的社会性别信号。我们让参与者分别或同时沿着经实证测量的氧合血和脱氧血颜色轴来调整颜色校准的面部照片，以优化健康外观。参与者将皮肤血液颜色，尤其是氧合血颜色，提升至基础水平之上，以优化健康外观。因此，我们表明，皮肤的血液灌注和氧合作用以一种可能对配偶选择很重要的方式影响着人们对健康的认知。
