What is the correct time frame to vigorously rub hands together when washing them?

The recommended time frame for vigorously rubbing hands together when washing them is 15 to 30 seconds. This duration is crucial because it allows sufficient time for the soap to effectively remove dirt, bacteria, and viruses from the skin. Rubbing hands together generates friction, which is essential for breaking down and dislodging microbes that can cause infections.

During this 15 to 30 seconds, it's important to cover all areas of the hands, including between the fingers, under the nails, and on the backs of the hands. Thorough washing within this recommended time frame has been shown to significantly reduce the presence of pathogens, thereby promoting better hand hygiene and overall public health.

While longer washing times can be beneficial, extending the duration to 30 seconds or more may not be necessary for everyday handwashing unless dealing with specific contaminants or after certain activities.
