The human skin contains 2–4 million sweat glands, primarily eccrine (thermoregulatory) and apocrine (odor-producing). Patent sweat pores are essential for thermoregulation, hydration, and antimicrobial defense (via dermcidin). Occlusion occurs when keratinous debris, sebum, or external substances block the distal sweat duct, leading to anhidrosis (lack of sweating) and subsequent inflammatory sequelae. clogged sweat pores
