新研究改写出汗机制传统认知

Group 1 - The core finding of the research indicates that sweat does not form as droplets but rather emerges as a membrane that slowly rises from the pores and gathers on the skin surface, challenging traditional understanding of sweating mechanisms [1] - The study involved six healthy volunteers and utilized specialized clothing with internal water circulation and heating blankets to induce sweating, focusing on the forehead area [1] - The research revealed that sweat first penetrates the outermost layer of the skin (stratum corneum) before accumulating on the skin surface, and when cooling occurs, the sweat film evaporates, leaving a thin layer of salt [1] Group 2 - In a subsequent heating phase, sweat appeared more rapidly due to the salt layer formed during the first sweating phase, which accelerated the penetration of sweat through the stratum corneum, allowing for direct membrane formation on the skin [2] - Understanding the mechanisms of sweat generation can lead to the development of more efficient sweat-wicking materials, functional clothing, and skincare products, providing new insights for temperature regulation and skin health management in extreme heat environments [2]
