When washing your hands, how long do you wash for?

• A. 60-90 seconds
• B. 40-60 seconds
• C. 5-10 seconds
• D. 30-45 seconds

Answer: (B)

The duration matters because soap and mechanical rubbing need time to break down oils and lift microbes from all hand surfaces. Washing for about 40 to 60 seconds gives enough contact time for the soap to work and for you to scrub thoroughly across palms, backs of hands, between fingers, under nails, and around the wrists. Shorter times—like 5–10 seconds—don’t reliably remove microbes, while 30–45 seconds may miss some areas if you rush, and 60–90 seconds is longer than typically needed and can dry the skin without extra benefit. So, 40–60 seconds is the best-balanced duration to achieve effective hand hygiene.
