how long to wash hands
You should wash your hands for at least 20 seconds of scrubbing with soap and water; many health agencies and hospitals recommend 20–30 seconds for good germ removal.
Quick Scoop: How long to wash hands
- Aim for 20–30 seconds of active scrubbing (not counting turning on water or drying).
- A common trick: hum the “Happy Birthday” song twice to hit roughly 20 seconds.
- Whole process (wet → soap → scrub → rinse → dry) often takes about 40–60 seconds total.
Simple step-by-step
- Wet hands with clean, running water.
- Add soap and lather well (palms, backs of hands, between fingers, thumbs, under nails, wrists).
- Scrub those areas for at least 20 seconds.
- Rinse thoroughly under running water.
- Dry with a clean towel or air dry.
When 20 seconds really matters
- After using the toilet or changing diapers.
- Before eating or preparing food (especially raw meat, eggs, seafood).
- After coughing, sneezing, or blowing your nose.
- After touching garbage, animals, or public surfaces (buses, railings, door handles).
During things like COVID waves or flu season, sticking to the full 20 seconds is especially important to cut down virus spread.
TL;DR: Scrub with soap for 20+ seconds every time (about “Happy Birthday” twice), and the whole routine will take under a minute while giving you solid protection against everyday germs.
