A global hygiene behavior study reveals: Across 12 countries on seven continents, an average of 54% of people wash their hands with soap five or more times daily. China has the lowest rate at just 25%. Everyone's hands carry vast amounts of bacteria, making them dirtier than elevator handrails.Let's examine an experiment: from left to right and top to bottom, we see bacterial cultures from microwave buttons, classroom desks, toilet faucets, lobby reception counters, elevator buttons, and fingerprints before handwashing. Next, we'll detail the most effective handwashing methods and techniques.Experts found bathroom faucets harbor the most bacteria, while unwashed hands also carry significant contamination. As the saying goes, "disease enters through the mouth," but more precisely, "disease enters through the hands." Though simple in appearance, handwashing involves considerable science. When to Wash Your Hands The National Health and Family Planning Commission of the People's Republic of China specifies ten situations requiring handwashing:These include: before and after meals; before and after using the restroom; before taking medication; after contact with blood, tears, nasal discharge, phlegm, or saliva; after cleaning tasks; after handling money; after physical contact with others; after outdoor play where dirt is encountered; after outdoor activities, work, or shopping; and before holding a child. Particular attention should be paid to disinfecting and washing hands thoroughly after contact with infectious materials.Additionally, wash your hands after cleaning children, as infant and child feces are teeming with pathogens—contrary to what many parents believe. Proper handwashing at this time significantly reduces the threat of germs to you and your family.

How to Wash Hands
According to the World Health Organization (WHO), handwashing involves 12 steps:
0. Wet hands thoroughly; (Skip this step for dry handwashing)
1. Apply sufficient soap (hand soap or hand sanitizer) to cover entire hands;
2.Rub palms together vigorously;
3. Cover left hand with right palm, interlock fingers, then reverse;
4. Press palms together, fingers interlocked;
5. Place back of one hand over the other, fingers interlocked;
6. Rotate and rub left thumb with right hand, then reverse;
7.Press the right palm against the left palm with fingers together, rotating and rubbing in both directions, then repeat with the left hand; (If using dry handwashing, stop here and wait for hands to dry)
8. Rinse hands thoroughly with water;
9. Dry hands with a disposable towel;
10. Use the towel to turn off the faucet;
11. Complete.
Next is standard water washing with soap/hand sanitizer.
How much hand sanitizer is appropriate?
Some people squeeze large amounts onto their hands, believing more is cleaner. This is actually counterproductive—such deep cleansing damages skin, preventing moisture retention and making it more susceptible to bacterial invasion.
How long should you wash?
The WHO recommends rubbing hands vigorously with soap for 20 seconds. The rich lather breaks down oils and dirt harboring germs while leaving hands pleasantly scented. Rinse thoroughly under running water for at least 15 seconds to remove all soap residue.The entire process takes 40-60 seconds—roughly the time it takes to sing "Happy Birthday" twice. For dry handwashing, the process takes about 23-30 seconds.
Here are some key points about handwashing.
What kind of water should you use?
Water temperature should be between 20–25°C (68–77°F). Avoid using water preheated to 37°C (98.6°F) by water heaters, as this temperature often promotes contamination by bacteria like Pseudomonas aeruginosa. If warm water is needed, mix hot and cold water before use. Crucially, never wash hands with stagnant water from a basin.Stagnant water is a breeding ground for bacteria. Washing hands with water left in a basin not only fails to reduce bacteria on hands but can even spread pathogenic microorganisms. How should hand hygiene products be stored? Solid soap should be kept clean and dry, as damp soap provides an ideal environment for bacterial growth.It's best to hang the soap with a string or use a porous soap dish that allows airflow to prevent water accumulation. Liquid soaps used in households are often stored in reusable, sealed containers. Avoid adding new liquid soap to partially used containers; instead, thoroughly clean the container after each use before refilling.
Finally, during dry seasons, frequent handwashing can cause skin dryness and flaking, increasing susceptibility to bacterial infections. Apply moisturizing hand cream or choose hand soaps containing aloe vera for hydration.
