We use our hands for almost everything—eating, working, touching our faces (way more than we realize). That’s why handwashing isn’t just a good habit, it’s one of the easiest and most effective ways to protect your health. It helps stop the spread of germs, keeps illnesses at bay, and literally saves lives. Let’s break down the right way to do it and why it matters so much more than you think.
Importance
Every time you touch a doorknob, phone, or even shake someone’s hand, you’re picking up germs. These germs can easily travel into your body when you rub your eyes, touch your nose, or eat food. Regular handwashing helps prevent the spread of:
- Cold and flu viruses
- COVID-19 and other respiratory infections
- Foodborne illnesses
- Norovirus and stomach bugs
- Eye infections like conjunctivitis
- Skin infections and more
According to the CDC, handwashing can reduce respiratory illnesses by up to 20%. That’s huge for something that only takes 20 seconds.
When
Not sure when to wash your hands? Here are the key times:
- Before and after eating or handling food
- After using the restroom
- After coughing, sneezing, or blowing your nose
- After touching pets or handling pet food
- After touching garbage
- After being in public places (like stores or public transport)
- Before and after caring for someone who’s sick
Basically, if your hands feel dirty—or even if they don’t—it’s probably time for a wash.
Technique
Handwashing works best when it’s done the right way. A quick splash of water won’t cut it. Follow these steps:
- Wet your hands with clean, running water (warm or cold is fine).
- Apply soap and lather well, covering all parts of your hands.
- Scrub for at least 20 seconds—that’s about the time it takes to sing “Happy Birthday” twice.
- Clean under your nails, between your fingers, and the backs of your hands.
- Rinse well under clean, running water.
- Dry with a clean towel or air dry.
Here’s a quick reminder in table form:
| Step | What to Do |
|---|---|
| Wet | Use clean, running water |
| Lather | Soap up all surfaces of your hands |
| Scrub | 20 seconds—don’t rush |
| Rinse | Remove all the soap and dirt |
| Dry | Use a clean towel or air dry |
Soap vs Sanitizer
What if you’re out and don’t have soap and water nearby? That’s when hand sanitizer comes in handy. But not just any kind—make sure it’s at least 60% alcohol.
- Use sanitizer when soap and water aren’t available
- Apply enough to cover all hand surfaces
- Rub for 20 seconds until hands feel dry
Sanitizer kills most germs, but it doesn’t remove dirt, grease, or chemicals—so soap and water is still the gold standard.
Kids
Teaching kids proper handwashing early helps build lifelong habits. Make it fun:
- Use songs or timers
- Reward good habits
- Set an example by washing your hands often too
Let them see handwashing as a normal, everyday thing—not just something they have to do.
Tips
A few extra things to keep in mind:
- Don’t forget your thumbs—they often get missed
- If you’re using a public restroom, use a paper towel to turn off the faucet or open doors
- Replace hand towels at home regularly
- Use lotion if your hands get dry—healthy skin is less likely to crack and harbor germs
Handwashing doesn’t just protect you—it protects everyone around you. In just 20 seconds, you can stop germs in their tracks and help build a healthier community.
