You should wash your hands for at least 20 seconds.
Washing your hands properly is crucial for preventing the spread of germs and staying healthy. The Centers for Disease Control and Prevention (CDC) recommends a minimum of 20 seconds for effective handwashing. This duration allows enough time for the soap to loosen and remove dirt, viruses, and bacteria from your skin.
Here's a breakdown of why 20 seconds is the recommended time:
-
Sufficient Contact Time: Twenty seconds ensures the soap has adequate contact time with all surfaces of your hands, including the backs of your hands, between your fingers, and under your nails.
-
Effective Germ Removal: Studies have shown that washing for at least 20 seconds significantly reduces the number of germs on your hands compared to shorter washing times.
-
Ease of Measurement: Twenty seconds is a relatively easy time frame to measure. You can hum the "Happy Birthday" song twice from beginning to end, which takes approximately 20 seconds.
So, remember to scrub thoroughly for at least 20 seconds each time you wash your hands!
