What temperature should the water be when washing hands?

• A. At least 90 degrees F
• B. At least 100 degrees F
• C. At least 110 degrees F
• D. At least 120 degrees F

Answer: (B)

The recommended temperature for washing hands is at least 100 degrees Fahrenheit. This temperature helps to ensure that the water is warm enough to effectively remove dirt, bacteria, and viruses from the skin while also providing comfort to the person washing their hands. Warm water can improve the lathering capability of soap, making it more effective in breaking down oils and removing germs. Using water that is too hot, such as temperatures around 120 degrees Fahrenheit or higher, can be uncomfortable or even harmful, leading to skin irritation or burns. Therefore, ensuring the water is at least 100 degrees F strikes a balance between effectiveness and safety. This is why this temperature is the recommended standard in handwashing guidelines.
