Physiologists have long regarded sweating as an effective and safe means of detoxification, and heavy metals are excreted through sweat to reduce the levels of such metals in the body. However, the body can sweat through many means. To elucidate the difference in the excretion of heavy metals among sweating methods, 12 healthy young university students were recruited as participants (6 men and 6 women). Sweat samples were collected from the participants while they were either running on a treadmill or sitting in a sauna cabinet. After they experienced continuous sweating for 20 min, a minimum of 7 mL of sweat was collected from each participant, and the concentrations of nickel (Ni), lead (Pb), copper (Cu), arsenic (As), and mercury (Hg) were analyzed. The results demonstrated that the sweating method affected the excretion of heavy metals in sweat, with the concentrations of Ni, Pb, Cu, and As being significantly higher during dynamic exercise than during sitting in the sauna (all p < 0.05). However, the concentrations of Hg were unaffected by the sweating method. This study suggests that the removal of heavy metals from the body through dynamic exercise may be more effective than removal through static exposure to a hot environment.
生理学家长期以来一直将出汗视为一种有效且安全的解毒方法，重金属通过汗液排出，以降低体内重金属的含量。但是，人体可以通过多种方式出汗。为了阐明出汗方式对重金属排泄的差异，招募了 12 名健康的年轻大学生作为参与者（6 名男性和 6 名女性）。在参与者在跑步机上跑步或坐在桑拿房时，收集他们的汗液样本。在连续出汗 20 分钟后，从每位参与者身上收集至少 7 毫升的汗液，并分析镍（Ni）、铅（Pb）、铜（Cu）、砷（As）和汞（Hg）的浓度。结果表明，出汗方式影响汗液中重金属的排泄，与坐在桑拿房中相比，动态运动时 Ni、Pb、Cu 和 As 的浓度明显更高（均 p < 0.05）。然而，Hg 的浓度不受出汗方式的影响。本研究表明，通过动态运动从体内去除重金属可能比通过静态暴露于热环境更有效。
