Why is it important to wash hands for at least 20 seconds?

Washing hands for at least 20 seconds is crucial primarily to ensure complete removal of germs. This duration has been shown to be effective in reducing the presence of bacteria and viruses on the hands, which is essential in preventing the spread of infections, especially in settings like food preparation and healthcare. Proper handwashing helps to break the chains of transmission of pathogens, thereby minimizing the risk of foodborne illness and safeguarding public health.

While complying with regulations is important in many contexts, those regulations often stem from the understanding of effective handwashing practices to enhance hygiene. Speeding up food preparation may seem beneficial, but it should never come at the cost of thorough hygiene practices. Saving resources is not typically a target of handwashing efforts; instead, the focus is on health safety and preventing disease outbreaks. Therefore, emphasizing the complete removal of germs aligns directly with health guidelines and best practices in hygiene.
