WHO Hand Washing Instructions and Their Importance
Short answer
The WHO hand washing instructions provide a clear, step-by-step method to clean hands effectively and reduce the spread of germs. By following these steps, anyone can remove dirt, viruses, and bacteria, helping prevent illnesses. Proper hand washing is a simple but powerful practice that protects personal and public health.
What Are the WHO Hand Washing Instructions?
The WHO hand washing instructions are a set of practical steps designed to clean hands thoroughly using soap and water. These instructions focus on covering all hand surfaces—including palms, backs, between fingers, and under nails—to remove germs effectively. The method is endorsed worldwide as a standard for hygiene, especially in healthcare settings but applicable for everyone. The process takes about 40-60 seconds and involves rubbing hands together with soap, rinsing under running water, and drying completely.
The goal is to physically remove or kill microorganisms that can cause diseases like colds, flu, and gastrointestinal infections. Unlike a quick rinse under water, the thorough rubbing and specific hand positions ensure that hidden bacteria or viruses are dislodged and washed away.
How Does the WHO Hand Washing Technique Work? (With an Example)
The technique works by combining mechanical action (rubbing hands together) with the cleansing properties of soap and water. Soap molecules break down the oils and dirt on your skin that trap germs, while rubbing loosens the germs so they can be rinsed off.
For example, imagine you have just touched a doorknob that has cold or flu viruses on it. If you only rinse your hands quickly with water, many viruses remain. But if you apply soap and follow the WHO steps—rubbing palms, backs, between fingers, and fingertips for 20-30 seconds—soap breaks down the virus envelope, and rubbing physically removes them. When you rinse and dry your hands, those viruses are washed away, greatly lowering the chance of infection.
Why Are WHO Hand Washing Instructions Important for Everyone?
Hand washing is one of the most effective ways to stop the spread of infections in everyday life. Whether at home, work, or school, clean hands prevent illnesses from spreading to yourself and others. This is especially crucial during cold and flu season, outbreaks, or pandemics.
For adults managing families, workplaces, or public settings, following these instructions protects vulnerable people such as children, elderly, or those with weakened immune systems. It also reduces the need for antibiotics by lowering infection rates. Proper hand washing is a simple, cost-free action with massive health benefits.
What Common Terms Are Often Mixed Up with WHO Hand Washing Instructions?
People sometimes confuse "hand washing" with "hand sanitizing," "hand rubbing," or "hand scrubbing." While related, these terms have distinct meanings:
- Hand Washing: Using soap and water to clean hands physically, the method WHO promotes.
- Hand Sanitizing: Using alcohol-based gel or foam to kill germs when soap and water aren’t available.
- Hand Rubbing: Often refers to using sanitizer or rubbing hands together vigorously.
- Hand Scrubbing: A more intensive cleaning often done in medical settings, sometimes using brushes.
Knowing these differences helps you choose the right method for each situation. For example, hand sanitizing is convenient but does not remove visible dirt, so WHO recommends hand washing when hands are visibly soiled.
How Can You Follow the WHO Hand Washing Steps Effectively?
Here are the WHO hand washing steps you can follow to clean your hands properly:
- Wet hands with clean running water.
- Apply enough soap to cover all hand surfaces.
- Rub palms together.
- Rub the back of each hand.
- Interlace fingers and rub between them.
- Rub the backs of fingers on opposing palms.
- Rub thumbs thoroughly.
- Rub fingertips and nails on palms.
- Rinse hands well under running water.
- Dry hands completely with a clean towel or air dry.
Each step should last a few seconds, and the entire process typically takes 40-60 seconds. This method ensures every part of the hand is cleaned.
What Should You Do Next to Maintain Hand Hygiene?
After learning and practicing the WHO hand washing instructions, integrate hand hygiene into your daily routine:
- Wash hands before eating, after using the restroom, after coughing or sneezing, and after touching public surfaces.
- Use hand sanitizer only when soap and water are not available.
- Teach children and coworkers these steps for community health benefits.
- Keep soap and clean towels available in your home and workplace.
- Avoid touching your face with unwashed hands.
Keeping hands clean reduces germs and illness risk, improving overall health and well-being for you and those around you.
How Does Proper Hand Washing Fit Into Broader Hygiene Practices?
Hand washing is part of a wider set of hygiene habits that include safe food handling, respiratory etiquette (covering coughs and sneezes), and cleaning frequently touched surfaces. Together, these habits create layers of protection against infections. For example, washing hands before food preparation prevents contamination, while covering your mouth when coughing limits germs spreading to your hands in the first place.
Understanding this broader context helps make hand washing a purposeful part of a healthy lifestyle rather than an isolated task.

Frequently asked questions
How long should I wash my hands according to WHO?
The WHO recommends washing hands for 40 to 60 seconds to ensure thorough cleaning of all hand surfaces. This time allows soap to break down germs and rubbing to remove them effectively before rinsing.
Can hand sanitizer replace hand washing?
Hand sanitizer is useful when soap and water aren’t available, but it does not remove dirt or some types of germs. WHO advises washing with soap and water when hands are visibly dirty or greasy for best results.
What is the difference between hand washing and hand scrubbing?
Hand washing involves cleaning hands with soap and water for general hygiene. Hand scrubbing is a more intense process, often used by healthcare workers before surgery, involving brushes to clean under nails and skin crevices more thoroughly.
Why is drying hands important after washing?
Drying hands removes any remaining germs and prevents skin irritation. Wet hands transfer bacteria more easily than dry hands, so using a clean towel or air drying is an essential final step.
How often should I wash my hands daily?
Wash hands regularly throughout the day, especially before eating, after using the restroom, after blowing your nose, and after touching public surfaces. Frequent hand washing helps maintain hygiene and reduces infection risk.
Are there specific hand washing guidelines for healthcare workers?
Yes, healthcare workers follow stricter protocols to prevent infection spread in medical settings, including using alcohol-based hand rubs and washing at key moments during patient care. See detailed guidance in [Hand Washing Guidelines for Healthcare Workers](#r5).
