洗手大學問
除了風寒、濕熱、傷食或脾虛體質導致腹瀉外，常見的腹瀉還包括感染病菌或病毒引致的腸胃炎，例如冬季較常見的諾如病毒(舊稱諾沃克病毒)，透過糞便及飛沫傳染，進食前和如廁後洗手是其中一個預防方法。手我們每天都洗，但你的洗手方法正確嗎？會否踏進了以下五個洗手誤區？
誤區一
❌只用清水洗手
⭕用肥皂/梘液更能殺滅病毒和細菌
誤區二
❌水沾濕雙手就洗完
⭕揉搓雙手最少20秒才能把病菌搓掉，時間等於唱兩次生日歌，記著要揉搓手掌、手背、指隙、指背、拇指、指尖及手腕
誤區三
❌用衫褲擦乾雙手
⭕手再次沾上衣褲的細菌等於沒有洗手，如果沒有抹手紙不如讓雙手風乾更好
誤區四
❌懶去洗手間，長期用酒精洗手液擦手就算
⭕酒精並不能消滅所有病毒，而且酒精對皮膚有刺激性，肥皂還是目前最有效又便宜的潔手方法。
誤區五
❌暖水洗手比較乾淨
⭕熱量可以殺滅細菌的概念沒有錯，但要去到滾燙程度才可以，研究發現暖水和室溫水洗手的殺菌程度沒有分別。
Do’s and don’ts of hand washing
In addition to diarrhea caused by cold-wind, damp-heat, poor eating habits, or asthenic weak spleen, common diarrhea also includes gastroenteritis caused by infection by bacteria or viruses. Norovirus is common in winter, and people are usually infected through fecal matter. Washing hands before eating and after going to the toilet are preventive methods. We wash our hands every day, but do you wash your hands correctly? Do you have commit these five errors?
Misunderstanding 1
❌Wash your hands with water only
⭕Use soap to kill viruses and bacteria
Misunderstanding 2
❌Assume you are done when your hands are wet
⭕Rub your hands for at least 20 seconds to get rid of the germs. The time is equal to singing the birthday song twice. Remember to rub your palms, back of hands, finger gaps, back of fingers, thumb, fingertips and wrists.
Misunderstanding 3
❌Dry your hands by rubbing on your clothes and pants
⭕Wiping your hands with clothes and pants can contact bacteria making it same as not washing your hands. It is better to dry your hands with air if you do not have a tissue.
Misunderstanding 4
❌Too lazy to go to the bathroom and clean your hands with alcohol hand sanitiser for long periods of time
⭕Alcohol does not kill all viruses, and can be irritating to the skin. Soap is the most effective and cheapest way to clean your hands.
Misunderstanding 5
❌Washing your hands with warm water makes them cleaner.
⭕It is correct that heat can kill bacteria, but it can only be done with hot boiling water.
Studies have found that there is no difference in the degree of sterilisation of hands in warm water and room temperature water.
