How long should you wash your hands when using soap and water?

Washing your hands with soap and water for at least 20 seconds is essential for effectively removing germs and contaminants. This duration allows the soap to work effectively, breaking down oils and dirt while ensuring that all areas of the hands, including between fingers and under nails, are properly cleaned. The 20-second guideline is based on studies showing that this time frame significantly reduces the presence of pathogens on the skin, which is crucial in preventing the spread of infectious diseases.

Shorter washing times may not thoroughly eliminate germs, potentially leaving harmful bacteria and viruses on the skin. Therefore, the emphasis on at least 20 seconds is a key public health recommendation for effective hand hygiene.
