From argument and a few personal observations, the hypothesis has crystallised that the miliaria commonly occurring in unacclimatised Caucasians visiting hot climates is caused by exposure to ultraviolet irradiation, by an effect on the cells of the upper epidermis, which eventually allows a split to develop between them and the new stratum corneum that grows up beneath, into which sweat from the disrupted ducts can collect as microcysts. This dehiscence is the probable explanation of sunburn peeling and photo-onycholysis. It is concluded that duct disruption, not blockage or dysfunction, is the immediate cause of the miliarias.
基于论证和一些个人观察，这一假说已经明确：初到炎热气候地区的未适应环境的白种人身上常见的粟丘疹是由紫外线照射引起的，紫外线作用于表皮上层细胞，最终导致这些细胞与下方新生长的角质层之间出现分离，来自破裂导管的汗液会在分离处聚集成微囊肿。这种裂开可能是晒伤脱皮和光甲脱离的原因。由此得出结论，导管破裂而非堵塞或功能障碍是粟丘疹的直接成因。
