Answer :
In the context of handwashing, the statement that "Hand washing should last a minimum of 15 seconds" is generally considered False. The recommended minimum duration for effective handwashing is actually 20 seconds, not 15 seconds. Here's why:
1. **Effective Hand Washing**: Washing your hands for at least 20 seconds allows enough time for the soap to break down and remove germs, viruses, and bacteria effectively from your hands. This thorough cleansing process is essential for maintaining good hand hygiene.
2. **Proper Technique**: To ensure proper handwashing, you should follow the steps recommended by health authorities, such as the CDC (Centers for Disease Control and Prevention) and the WHO (World Health Organization). This includes wetting your hands, lathering with soap, scrubbing all surfaces of your hands, including between your fingers and under your nails, and rinsing thoroughly.
3. **Importance of Duration**: While 15 seconds might seem sufficient, studies and experts recommend a longer duration of 20 seconds to achieve optimal cleanliness and reduce the spread of germs, especially during situations like flu season or a global pandemic.
In conclusion, to effectively clean your hands and reduce the risk of spreading infections, it is recommended to wash your hands for a minimum of 20 seconds, not 15 seconds. This extra time ensures thorough cleaning and helps protect both yourself and others from illnesses.
