How long should you wash your hands to effectively lower the risk for infection?

Washing your hands for 20 seconds is widely recommended as an effective duration to significantly reduce the risk of infection. This timeframe allows sufficient lathering and scrubbing to remove pathogens, including bacteria and viruses, from the surfaces of the hands. The 20-second rule is supported by health organizations, which emphasize that thorough washing—encompassing the fronts, backs, and in between fingers, as well as under nails—is crucial in promoting hygiene practices.

The effectiveness of handwashing also relies on using soap and water, as soap helps break down oils and dirt, making it easier to remove germs. While shorter durations of handwashing might remove some contaminants, they may not be adequate to ensure a thorough cleansing that significantly lowers infection risks. Therefore, ensuring your handwashing routine lasts 20 seconds is key to maintaining proper hygiene and minimizing the potential for illness.
