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

Washing hands for 20 seconds with hot, soapy water is recommended to effectively remove dirt, bacteria, and viruses. This duration allows sufficient time to thoroughly scrub all areas of the hands, including between the fingers, under the nails, and around the thumbs. The use of warm water helps to activate the soap, enhancing its ability to break down grease and grime while also providing a comfortable washing experience.

While other options suggest varying durations or temperatures, they do not meet the optimal criteria for hand hygiene. Shorter washing times may not effectively eliminate pathogens, and using cold water is less effective at dissolving soap and achieving a good lather. Moreover, washing with lukewarm water for an extended period may seem beneficial but can also be ineffective if not adhering to the correct soap application and timing. Proper handwashing is essential in preventing the spread of illness in food service and other settings where hygiene is critical.
