What is the minimum time recommended for washing hands with soap and water?

• A. 10 seconds
• B. 15 seconds
• C. 20 seconds
• D. 30 seconds

Answer: (C)

The minimum time recommended for washing hands with soap and water is 20 seconds. This duration has been established based on studies showing that effective handwashing requires sufficient time to remove dirt, bacteria, and viruses from the skin. The process of lathering soap and scrubbing the surfaces of the hands, including between the fingers and under the nails, is crucial for effective hygiene. Washing hands for 20 seconds ensures that the soap has enough time to work, allowing it to break down germs and impurities effectively. This practice is especially important in preventing the spread of infectious diseases, as thorough handwashing can significantly reduce the likelihood of contamination. The emphasis on this time frame cannot be overstated—it serves as a practical guideline that can be easily remembered, often likened to singing the "Happy Birthday" song twice.
