How long should you wash your hands to ensure proper hygiene?

  1. 10-15 seconds

  2. 15-20 seconds

  3. 20-30 seconds

  4. 30-40 seconds

The correct answer is: 20-30 seconds

Washing hands for 20-30 seconds is recommended to ensure proper hygiene because it provides sufficient time to remove dirt, bacteria, and viruses effectively. This duration allows for thorough scrubbing of all parts of the hands, including the backs, between fingers, and under nails, which are common areas where pathogens can reside. Health organizations, such as the Centers for Disease Control and Prevention (CDC), recommend this timeframe to maximize the effectiveness of handwashing in reducing the risk of infection and disease transmission. The technique and duration are vital in healthcare settings, where a high standard of hygiene is essential to protect both patients and healthcare providers.
