What is the recommended safe temperature for hot water?

The recommended safe temperature for hot water is 120 degrees Fahrenheit. This temperature helps to prevent scalding injuries, which can occur at higher temperatures, especially in children and the elderly. Water at 120 degrees is hot enough to provide comfort and efficiency for typical uses, such as bathing and cleaning, while still minimizing the risk of burns.

For instance, water heated to temperatures above 140 degrees Fahrenheit can cause severe burns in just a matter of seconds, making it too dangerous for general safety. Lower temperatures, such as 100 degrees Fahrenheit, may not be effective for sanitizing or providing comfortable hot water for practical use. Maintaining water at around 120 degrees strikes a balance between safety and functionality, which is why it is widely recommended.
