How long should friction be used for when washing hands?

Using friction for at least 20 seconds when washing hands is crucial for effective sanitation. This duration allows enough time to thoroughly cleanse all areas of the hands, including the palms, backs, between the fingers, and under the nails. The friction generated during this process helps to physically remove dirt, microbes, and other contaminants from the skin.

Research and health guidelines emphasize that washing hands for 20 seconds significantly reduces the presence of pathogens, which is essential in preventing the spread of infections, especially in healthcare settings. The practice is a critical part of maintaining hygiene standards among Certified Nursing Assistants and in the overall context of patient care. Using a timer or singing a short song that lasts about 20 seconds can aid individuals in ensuring they wash their hands long enough to be effective.
