Washing your hands might seem like a simple task, but it's one of the most effective ways to prevent the spread of germs and stay healthy. In fact, the World Health Organization (WHO) estimates that hand hygiene can reduce the number of people who get sick by up to 50%. So, let's dive into the world of soap and water and explore the art of hand washing, according to the Centers for Disease Control and Prevention (CDC) and the WHO.
Why is Hand Washing Important?
Our hands touch many surfaces and can pick up germs from them. If we then touch our face, especially our eyes, nose, or mouth, we can transfer those germs into our body and make ourselves sick. Hand washing is a simple yet powerful way to prevent this transfer and keep us healthy.
When Should You Wash Your Hands?
You should wash your hands frequently throughout the day, especially:
- After using the toilet
- Before eating
- After blowing your nose, coughing, or sneezing
- After touching animals, animal feed, or animal waste
- After handling garbage
- After touching commonly used surfaces or objects
How to Wash Your Hands: The 5 Steps
The CDC and the WHO recommend a five-step process for effective hand washing:
-
Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
Lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.
Scrub your hands for at least 20 seconds. Need a timer? Hum the "Happy Birthday" song twice.
Rinse your hands well under clean, running water.
Dry your hands using a clean towel or air dry them.
What if Soap and Water Aren't Available?
If soap and water aren't available, the CDC recommends using an alcohol-based hand sanitizer that contains at least 60% alcohol. However, hand sanitizers aren't as effective when your hands are visibly dirty or greasy. Always use soap and water when possible.
Hand Washing Techniques to Avoid
While it might seem counterintuitive, there are some hand washing techniques you should avoid:
-
Don't turn the faucet off with a used towel. This can transfer germs back onto your clean hands.
Don't use a public restroom's hand dryer. These can blow around germs and make your hands less clean.
Don't use antibacterial soap. Regular soap is just as effective and doesn't contribute to antibiotic resistance.
Hand washing is a simple, yet powerful tool in the fight against germs. By following these guidelines, you can help keep yourself and others healthy. So, let's get washing!
