Sweat discharged as a result of exposure to sauna plays an important role in removing inorganic ions accumulated in the body, including heavy metals. In this study, inorganic ions (toxic and nutrient elements) excreted in the form of sweat from the body using a water-filtered infrared-A (wIRA) sauna were determined using inductively coupled plasma sector field mass spectrometry. The analyzed elements included eight toxic elements (Al, As, Be, Cd, Ni, Pb, Ti, and Hg) and 10 nutrient elements (Ca, Co, Cr, Cu, Fe, Mg, Mn, Se, V, and Zn), and their correlations were determined. Analysis of the sweat obtained from 22 people using the wIRA sauna showed a higher inorganic ion concentration than that obtained from conventional activities, such as exercise or the use of wet sauna, and the concentration of toxic elements in sweat was higher in females than in males. Correlation analysis of the ions revealed a correlation between the discharge of toxic elements, such as As, Be, Cd, and Ni, and discharge of Se and V, and Ni was only correlated with Mn. This study provides fundamental information on nutritional element supplementation when using wIRA sauna for detoxification.
由于暴露在桑拿房中而排出的汗液在去除体内积累的无机离子（包括重金属）方面起着重要作用。在这项研究中，使用水过滤的红外-A（wIRA）桑拿，以汗液的形式从体内排出的无机离子（有毒和营养元素）采用电感耦合等离子体质谱扇形场质谱法进行了测定。分析的元素包括八种有毒元素（Al、As、Be、Cd、Ni、Pb、Ti 和 Hg）和十种营养元素（Ca、Co、Cr、Cu、Fe、Mg、Mn、Se、V 和 Zn），并确定了它们的相关性。对 22 名使用 wIRA 桑拿的人的汗液进行分析表明，其无机离子浓度高于运动或湿桑拿等常规活动，且女性汗液中的有毒元素浓度高于男性。离子的相关分析表明，有毒元素（如 As、Be、Cd 和 Ni）的排出与 Se 和 V 的排出之间存在相关性，而 Ni 仅与 Mn 相关。这项研究为使用 wIRA 桑拿进行解毒时营养元素的补充提供了基础信息。
