Clothing, for example, doesn't need to be washed after every wearing, and you don't need to wash your hair every day. Don't soak in soapy bathwater frequently, and avoid contact with tabletops in public places that might carry cleanser residue.
例如衣物不必一穿就洗、頭髮不必天天洗、不要常泡熱水浴、在公共場所不要隨手觸摸桌面（上面往往殘留清潔劑）等等。
