Understanding the WHO's 7 Steps for Effective Hand Hygiene
In today's world, understanding and practicing proper hand hygiene is more crucial than ever. Germs and viruses are all around us, and our hands are often the primary way they spread. While many of us might think we know how to wash our hands effectively, the World Health Organization (WHO) has outlined a specific, seven-step process that ensures the most thorough cleaning. This guide will break down each of these essential steps, explaining why they are important and how to perform them correctly. By following these simple yet powerful techniques, you can significantly reduce your risk of illness and help protect those around you.
Why Are These 7 Steps Important?
The WHO's seven-step handwashing technique is designed to cover all surfaces of your hands, ensuring that no area is missed. This comprehensive approach is vital because bacteria and viruses can hide in nooks and crannies, under fingernails, and between fingers. Simply rinsing your hands or a quick scrub may not be enough to eliminate these harmful microorganisms. By meticulously following each step, you are actively removing germs, preventing the spread of infections like the common cold, flu, and more serious diseases. This practice is a cornerstone of public health and personal well-being.
The 7 Steps to Effective Handwashing
Let's dive into the detailed breakdown of the WHO's recommended hand hygiene process:
-
Step 1: Wet Your Hands.
Begin by wetting your hands thoroughly with clean, running water. This can be either warm or cold water. The water should be sufficient to moisten all surfaces of your hands. This initial step helps to lather the soap more effectively and loosen any dirt or grime.
-
Step 2: Apply Soap.
Apply enough soap to cover all surfaces of your hands. Whether you're using liquid soap from a dispenser or a bar of soap, ensure you have a generous amount. This is crucial for creating the lather that will lift and remove germs.
-
Step 3: Lather and Rub Hands Palm to Palm.
Rub your hands palm to palm. This means placing one palm over the back of the other hand and interlinking your fingers, then repeating this motion with the other hand. This movement helps to distribute the soap evenly across the entire surface of your palms.
-
Step 4: Rub Backs of Hands and Between Fingers.
Rub the back of each hand with the palm of your other hand, with fingers interlocked. This step is critical for cleaning the often-neglected back surfaces of your hands and the areas between your fingers, where germs can easily accumulate. Ensure you spend adequate time in this motion.
-
Step 5: Rub Palm to Palm With Fingers Interlaced.
Rub palm to palm with your fingers interlaced. This motion cleans the very tips of your fingers and the undersides of your fingernails. The interlacing of fingers ensures that every crevice is reached, maximizing the cleaning effect.
-
Step 6: Rub Backs of Fingers to Opposing Palms With Fingers Interlocked.
Rub the backs of your fingers to opposing palms with your fingers interlocked. This specific movement targets the backs of your fingers, which can easily harbor germs. By interlocking your fingers and rubbing, you effectively clean these surfaces.
-
Step 7: Rub Each Thumb Clasped in the Opposite Hand.
Rub each thumb, clasped in the opposite hand. Rotate your hand to ensure the entire surface of the thumb is cleaned. This step is often overlooked but is essential for removing germs that can linger on your thumbs.
Additional Crucial Steps After the 7 Steps
While the seven steps focus on the cleansing process, there are two equally important concluding actions:
-
Rinse Your Hands.
Once you have completed all seven steps of lathering and rubbing, rinse your hands thoroughly under clean, running water. Make sure all the soap is washed away. Residual soap can irritate the skin and may not be as effective in removing germs.
-
Dry Your Hands.
Dry your hands completely using a clean towel or air dryer. Damp hands can still transfer germs. Using a disposable towel is ideal, and use that towel to turn off the faucet if you are in a public restroom to avoid recontaminating your hands.
When Should You Wash Your Hands?
It's not just about the technique; it's also about the timing. The WHO recommends washing your hands frequently, especially:
- Before, during, and after preparing food
- Before eating food
- Before and after caring for someone who is sick
- Before and after treating a cut or wound
- After using the toilet
- After changing diapers or cleaning up a child who has used the toilet
- After blowing your nose, coughing, or sneezing
- After touching an animal, animal feed, or animal waste
- After handling pet food or pet treats
- After touching garbage
- When your hands are visibly dirty
Hand Sanitizer vs. Soap and Water
While hand sanitizers can be effective when soap and water are not available, it's important to remember that they are not a perfect substitute. Hand sanitizers are most effective against bacteria and some viruses, but they may not work well against all types of germs, particularly if your hands are visibly dirty or greasy. Soap and water physically remove dirt and germs, which is generally considered more effective for thorough hand hygiene.
The WHO emphasizes that consistent and correct handwashing is one of the simplest and most effective ways to prevent the spread of infections.
Frequently Asked Questions (FAQ)
How long should I wash my hands for?
The entire process of washing your hands, from wetting them to drying them, should take at least 20 seconds. This includes the time spent on each of the seven washing steps.
Why is it important to use soap?
Soap works by breaking down the outer layer of many germs, making them easier to wash away. It also helps to lift dirt and oils from your skin, which can trap germs.
What if I don't have running water?
If running water is not available, the WHO recommends using an alcohol-based hand sanitizer that contains at least 60% alcohol. However, if your hands are visibly dirty or greasy, soap and water are preferred.
Why is drying my hands important?
Damp hands can easily transfer germs to surfaces and other people. Thoroughly drying your hands with a clean towel or air dryer helps to remove any remaining moisture where germs can thrive.
Are there any special considerations for children?
Yes, children may need more supervision to ensure they are following all the steps correctly and for the recommended duration. Making handwashing a fun routine can help them develop good habits early on.
