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?
❌Wash your hands with water only
⭕Use soap to kill viruses and bacteria
❌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.
❌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.
❌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.
❌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.
