What is the recommended duration for washing hands?

• A. Wash hands for at least 20 seconds
• B. Wash hands for 5 seconds
• C. 1 minute
• D. 30 seconds

Answer: (A)

The key idea is giving enough time for soap and friction to remove germs from all hand surfaces. Washing for at least twenty seconds ensures you thoroughly cover palms, backs of the hands, between the fingers, under the nails, and around the thumbs. This duration provides the necessary contact time for soap to lift and rinse away microbes when you scrub and rinse.

Five seconds isn’t enough to reach every area, so germs can remain. Thirty seconds or a minute do more than the minimum, which is fine in practice, but the standard recommendation is a minimum of twenty seconds because it reliably balances effectiveness with practicality in busy settings like athletic facilities.
