Hand Washing Definition According to WHO Guidelines
Short answer
Hand washing, according to the World Health Organization (WHO), is the deliberate process of cleaning hands using soap and water to physically remove germs, dirt, and harmful substances. It involves specific steps lasting 40-60 seconds to ensure thorough cleaning, significantly reducing the spread of infections and protecting individual and public health.
What is hand washing according to WHO?
Hand washing, as defined by the World Health Organization, is the act of cleaning hands by applying soap and water and rubbing all hand surfaces together to remove microorganisms, dirt, and harmful agents. The WHO highlights that hand washing is not simply rinsing hands with water; it is a methodical process aimed at interrupting the transmission of germs that cause illnesses such as diarrhea, respiratory infections, and other infectious diseases. The soap helps loosen the oils and dirt where germs hide, while the physical rubbing dislodges these germs from the skin's surface. The final rinsing step then washes these germs away.
WHO’s definition emphasizes that hand washing is a critical public health measure—it’s an accessible, practical way anyone can protect themselves and others. It is recommended for all age groups, in homes, schools, workplaces, and especially healthcare settings. The organization promotes this practice globally, recognizing it as one of the simplest and most cost-effective methods to prevent disease. Soap doesn’t have to be antibacterial; regular soap works well when combined with proper technique.
How does the WHO recommend hand washing works?
The WHO prescribes a detailed six-step hand washing technique designed to cover all hand surfaces. This routine should take 40 to 60 seconds. A person begins by wetting their hands with clean water, then applying a sufficient amount of soap to cover hands completely. Next, they rub their palms together to create a lather. The process continues by rubbing the back of each hand with the opposite palm, then interlacing fingers to clean between them.
To make this clearer, imagine someone who earns $400 a month and works in a market where many people touch the same surfaces. By washing their hands following WHO steps before handling food or after touching money, they reduce the chance of getting sick or passing germs to their family. Specifically, the steps cover tricky areas like thumbs and fingertips, which are often missed but harbor many germs.
The six WHO steps are:
- Palm to palm rubbing.
- Right palm over left dorsum and vice versa.
- Palm to palm with fingers interlaced.
- Backs of fingers to opposing palms with fingers interlocked.
- Rotational rubbing of thumbs.
- Rotational rubbing of fingertips on palms.
After these rubbings, thorough rinsing under clean running water removes all loosened germs and soap residue. Finally, drying hands with a clean towel or air drying is important because wet hands can spread germs more easily than dry ones.
Why does hand washing matter for everyone?
Hand washing matters universally because hands are the most common way germs are transferred from one person to another or to surfaces that others will touch. Germs can enter the body through the mouth, nose, or eyes after touching contaminated hands. Good hand hygiene is one of the most effective ways to prevent illnesses like colds, flu, stomach infections, and even serious diseases such as COVID-19.
For the general adult population, this means protecting themselves, their families, and their communities from avoidable sickness. For example, a parent caring for young children who wash their hands regularly reduces the chance of passing on viruses that cause diarrhea or respiratory infections. Workers in food service, schools, and healthcare benefit from reducing absenteeism due to illness.
Beyond personal protection, hand washing helps public health by lowering disease outbreaks. Clean hands reduce the spread of germs on commonly touched surfaces like doorknobs, counters, and phones. This is especially important in crowded or shared spaces. Practicing proper hand hygiene is a simple act with powerful results in preventing disease, improving overall community well-being.
What related terms do people confuse with hand washing?
Several terms related to hand hygiene are often confused with hand washing. Understanding the differences helps ensure proper hygiene practices.
- Hand hygiene is the broadest term, referring to all practices that maintain clean hands. This includes hand washing, hand sanitizing, and sometimes nail care.
- Hand sanitizing involves using an alcohol-based hand rub or gel to kill germs on the skin. While convenient when soap and water are unavailable, hand sanitizers do not physically remove dirt or some types of germs like certain viruses or chemicals.
- Hand rubbing is the action of applying sanitizer or rubbing hands during washing.
- The spelling varies: some use “handwashing” as one word, while WHO and many public health sources use “hand washing” (two words). Both are acceptable, but the two-word version is standard in WHO documents.
People sometimes mistake quick rinsing or wiping hands with a dry towel for washing. True hand washing requires soap, water, and rubbing all parts of the hands for at least 40 seconds. Misunderstanding these terms can lead to skipping key steps and reducing effectiveness.
What should you do next to follow WHO hand washing guidelines?
To adopt WHO hand washing guidelines into daily life, begin by ensuring access to clean water and soap at home, work, school, and public places. Set up a hand washing station with visible instructions on the six-step technique to remind everyone to follow the process fully.
Here’s a simple action plan to start:
- Keep soap and clean water within easy reach near toilets and eating areas.
- Teach all family members or coworkers the exact hand washing steps, using clear language or demonstrations.
- Wash hands before meals, after using the restroom, after coughing or sneezing, and after touching potentially contaminated surfaces.
- Use a clean towel or air dry your hands thoroughly afterward.
- Carry a hand sanitizer with at least 60% alcohol for situations where soap and water are not available, but wash hands properly as soon as possible afterward.
Encourage children and others to practice regularly by making hand washing fun—sing a 20-second song or use colorful posters. Reinforce the habit in schools and workplaces by providing supplies and time for hand washing breaks.
How can hand washing be taught to different audiences effectively?
Teaching hand washing varies by age group and setting. For children, simple and engaging methods work best. Using stories, songs, or visual aids helps them remember the steps and understand why hand washing matters. For example, a children’s song about washing hands or a game counting the seconds can motivate them to practice consistently.
For adults, clear, factual explanations about how hand washing prevents disease and the correct technique encourage compliance. Workplace training sessions or community health talks can reinforce this knowledge. Healthcare workers require more rigorous instruction following WHO’s healthcare-specific guidelines to prevent infection transmission in clinics and hospitals.
When teaching, use exact phrases like: “Wet your hands with clean water, apply enough soap to cover all surfaces, rub your hands palm to palm for 20 seconds, and don’t forget the thumbs and fingertips.” Repeating this wording helps learners internalize the process.
Demonstrations, practice sessions, and feedback improve hand washing skills across all groups. Visual posters at sinks showing each step help remind everyone to wash thoroughly.
What are common hand washing mistakes to avoid?
Many people unintentionally reduce the effectiveness of hand washing by making common errors. These mistakes include:
- Rushing the process: Skipping steps or washing hands for only a few seconds leaves germs behind.
- Not using soap: Water alone cannot remove oils and microbes effectively.
- Missing key areas: Thumbs, fingertips, and between fingers are often neglected but harbor many germs.
- Touching contaminated surfaces after washing: Turning taps off or opening doors with clean hands can recontaminate them. Use a paper towel to turn off faucets or open doors when possible.
- Not drying hands properly: Wet hands spread germs more easily than dry ones; always dry hands completely with a clean towel or air dryer.
- Using expired or poor-quality soap: Soap that is old or of low quality may not lather well or remove germs effectively.
By avoiding these errors and sticking to WHO’s recommended technique, hand washing becomes a powerful tool to prevent illness.
