C. 135 deg F
D. 98 deg F
The Correct Answer and Explanation is :
The correct answer is D. 98 deg F.
Explanation:
When washing hands, the temperature of the water should be comfortable, typically around 98°F (37°C), which is close to the body’s natural skin temperature. Water that is too hot can cause skin irritation, discomfort, and even burns, especially with prolonged exposure. On the other hand, water that is too cold may make it harder to remove dirt and grease effectively and may also discourage people from washing their hands thoroughly.
The main goal when washing hands is to remove dirt, oil, and germs from the skin. The Centers for Disease Control and Prevention (CDC) recommends washing hands with soap and water for at least 20 seconds. The temperature of the water is less important than the process of rubbing the hands together, creating friction that helps remove germs. However, choosing a temperature that encourages people to wash for the recommended time is crucial, and water at body temperature (98°F) is typically the most inviting.
Why not higher temperatures like 110-135°F?
- Water at 110°F or higher can cause discomfort or skin damage over time, leading to dry skin, irritation, and potential burns, especially if people wash their hands frequently.
- Water at 125°F or 135°F is generally considered too hot for handwashing, especially in settings where frequent washing occurs, like healthcare environments, as it increases the risk of burns or injury.
In healthcare or professional settings, it is essential to balance effective hand hygiene with comfort and safety. Ensuring the water is at a moderate, comfortable temperature promotes better compliance with proper handwashing techniques.
In conclusion, water at 98°F is ideal because it is close to body temperature, making it more likely that individuals will wash their hands thoroughly and comfortably without risking skin damage.
