What is the proper handwashing technique to prevent the spread of germs?

Washing hands with soap and water for at least 20 seconds is recognized as the most effective method for reducing the number of germs on hands. This technique involves thoroughly scrubbing all parts of the hands, including between the fingers, under the nails, and the wrists. The process of lathering with soap is crucial, as it aids in breaking down and loosening dirt, grease, and germs, making them easier to rinse away. The recommended time of at least 20 seconds ensures that sufficient friction is applied, enhancing the removal of pathogens.

In stark contrast, rinsing hands under hot water alone for a brief period does not effectively eliminate germs; it simply may not provide enough time for proper cleansing. Using hand sanitizer can also be helpful, particularly when soap and water are not available. However, it is not a substitute for thorough handwashing, as sanitizer may not remove all types of germs, especially when hands are visibly dirty or greasy. Soaking hands in a bleach solution is unsuitable for hand hygiene, as it can be harmful to the skin and does not provide the necessary cleansing that soap and water does. Thus, the recommended handwashing technique is essential for maintaining good health and preventing the spread of illnesses.
