汗液在排出的过程中,既带走了环境高温带来的热量,又带走了人体自身运动产生的多余热量。同时,它含有大量新陈代谢产生的废物,随着汗液排出,废物也随之排出体外。其次,汗液中含有一种叫做“乳酸”的物质,它能与皮脂腺分泌的脂肪酸结合,形成天然的杀菌剂,可以保护皮肤不被细菌侵袭。而频繁使用止汗剂会抑制人体正常排汗,使体内的热量无法排出,导致体温升高,出现头晕、胸闷等不适,甚至导致中暑,对人体有害而无益。
Sweat in the discharge process, both taking away the heat brought by environmental heat, but also took away the excess heat generated by the body’s own movement. At the same time, it contains a large amount of waste products generated by metabolism, with the sweat discharged, waste will also be excreted. Second, sweat contains a substance called lactic acid, which binds to fatty acids secreted by the sebaceous glands to form natural antiseptics that protect the skin from bacteria. The frequent use of antiperspirants will inhibit the body’s normal perspiration, the body’s heat can not be discharged, leading to elevated body temperature, dizziness, chest tightness and other discomfort, and even lead to heat stroke, harmful to the human body without benefit.
