What is required for proper handwashing?

Proper handwashing is essential for infection control and preventing the spread of illness. The recommended practice involves using warm water and soap. Warm water is more effective than cold water in removing dirt and germs because it helps to dissolve soap more effectively and can enhance lathering, which is essential for cleaning hands thoroughly.

When warm water is used, it encourages individuals to wash their hands for the recommended duration, usually at least 20 seconds. This practice helps to ensure that all areas of the hands are scrubbed well, including between fingers and under nails, where germs can hide.

Using only soap without water, whether it’s cold or hot, does not adequately remove dirt or microorganisms, as the water plays a crucial role in rinsing away the contaminants. While hot water may initially seem beneficial, it can cause skin irritation and damage if it's too extreme, making warm water the most suitable choice.
