How long should hands be washed according to the 20/20 rule?

The 20/20 rule emphasizes the importance of maintaining proper hygiene, particularly through handwashing. The correct duration for which hands should be washed according to this rule is 20 seconds, which is a universally recognized standard for effective handwashing. Washing hands for at least this duration helps ensure that germs and contaminants are thoroughly removed, significantly reducing the risk of illness.

In this context, the recommendation to wash hands every 20 minutes for 20 seconds underscores the strategy of frequent handwashing throughout the day, especially during times when the hands are likely to come into contact with germs. This regular habit promotes better health practices in various settings, such as in schools, hospitals, and workplaces. The focus on routine handwashing at specific intervals is part of effective hygiene management.
