3.使用肥皂

Washing with soap every day could affect our immunity, warns Dr Robyn Chutkan, of the Digestive Center for Women, Maryland.
馬里蘭州婦女消化中心的蘿賓·庫特坎博士警告稱，每天用肥皂洗澡可能會影響我們的免疫力。

Dr Chukan said it strips our skin of the bacteria that keeps us free from conditions like acne and eczema.
庫特坎博士說肥皂會剝離皮膚上的細菌，而這些細菌會抵御痤瘡和濕疹的生長。

Regular contact with grime, rather than being harmful, teaches these communities of bacteria how to tell the difference between friendly germs and harmful pathogens, she said.
經常接觸污垢不僅無害，還會教會這些細菌群如何辨別有益的細菌和有害的病菌，她說。
