It takes approximately 0.33 minutes (20 seconds) to properly wash your hands.
While the duration might seem short, the effectiveness of handwashing hinges on the technique and thoroughness, not just the time spent. Rinsing too soon can leave harmful germs on your hands.
Here's a breakdown of why the 20-second duration is crucial:
- Germ Removal: Washing for 20 seconds allows sufficient time to dislodge and remove germs effectively.
- Soap Action: The soap needs time to break down oils and fats on the skin that harbor germs.
- Complete Coverage: This duration ensures you have enough time to scrub all surfaces of your hands, including the backs, between your fingers, and under your nails.
You can use a timer or hum the "Happy Birthday" song twice to ensure you wash for the recommended time. The important thing is to make sure you scrub for at least 20 seconds.
