大凡人们每天都要洗手,而且要洗几次乃至十几次。用肥皂和清水洗手可以预防多种疾病,包括感冒、口腔疾病和食物中毒。不过,洗手也有个“科学”的问题,才能保持卫生。 ●经常洗手可以保持手部清洁,每次大小便、擤鼻子,用手掩口咳嗽或打喷嚏之后,都应洗手。处理食物之前之后,碰触家养猫狗等宠物之后均应用清水洗手。 People generally wash their hands every day, but also to wash several times and even a dozen times. Washing hands with soap and water can prevent a variety of illnesses, including cold, oral illness and food poisoning. However, there is also a “scientific” problem in hand washing to maintain hygiene. ● Always wash your hands to keep your hands clean. Wash hands after urinating, nose blowing, covering your mouth with cough or sneezing every time. After handling food, wash your hands with clean water after touching pets such as domestic cats and dogs.
