枕頭及床單每晚與我們為伴，與睡眠及健康息息相關。不過，如果長期不洗枕頭套及床單等床上用品，極容易滋生細菌及塵螨。所以我們應該要定期清潔床上用品，保持良好衛生習慣。
英國曼徹斯特大學曾進行一項有關枕頭的研究，檢測了多個長期使用的枕頭樣本，發現樣本均含有多種真菌及大量真菌孢子，最常見的是「煙麴黴」。另外，亦有樣本被檢出含有16種真菌，這些真菌除了會引致過敏，亦有機會感染肺部或其他器官，對健康造成影響。除了真菌，長期不洗枕頭套亦會令枕頭成為細菌溫床，含菌量比馬桶更高。
另外，人體在睡覺時約有一千五百萬個皮膚細胞脫落，繼而成為塵螨的食物。如果長期不洗床上用品，只會令塵螨有更多食物可賴以生存，並不斷繁殖。香港蟲害控制從業員協會會長梁廣源曾在接受訪問時透露，床上用品例如枕頭、被褥及枕頭都是塵螨重災區，大家應該定期進行清潔。除了枕頭套之外，當枕頭發黃及發黑就應該丟棄，定期更換枕頭。英國睡眠協會建議，半年至兩年更換一次枕頭為佳。
