What is the minimum temperature for hand washing water?

The minimum temperature for hand washing water is crucial for effective sanitation. Water at 100 degrees Fahrenheit is warm enough to help dissolve fats and oils, making it more effective at removing dirt, food residue, and bacteria from hands. This temperature provides comfort to the person washing their hands, encouraging thorough washing and reducing the likelihood of skipping this vital step.

Using water that is too cool may not effectively remove contaminants, while water that is too hot could lead to skin burns or discomfort, which could result in improper handwashing practices or avoidance altogether. Thus, maintaining the water temperature at 100 degrees Fahrenheit strikes a balance, promoting hygienic practices while ensuring safety and comfort.
