You should wash your hands frequently, 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
The Perfect Hand Washing Technique
Now that we've covered the why and when of hand washing, let's discuss the how. Here's a step-by-step guide to the perfect hand washing technique:
- 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. Make sure to 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.
If soap and water are not available, use an alcohol-based hand sanitizer containing at least 60% alcohol. However, remember that hand sanitizers are not as effective when hands are visibly dirty or greasy.
Mastering the art of hand washing is a simple yet powerful way to protect your health and the health of those around you. So, let's all commit to making hand washing a regular part of our daily routine. Your body (and the rest of the world) will thank you!
