Which Is The Correct Order For Handwashing

The simple act of washing our hands is a powerful weapon against the spread of germs and disease. But are you doing it right? Because of that, the order in which you wash your hands matters more than you might think. Let's dive into the correct handwashing sequence, explore the science behind each step, and understand why proper hand hygiene is essential for our health.

The Importance of Proper Handwashing

Handwashing is arguably the most effective way to prevent the transmission of infectious diseases. Still, our hands are constantly in contact with surfaces, objects, and other people, making them a breeding ground for bacteria, viruses, and other pathogens. These germs can easily transfer from our hands to our mouths, noses, or eyes, leading to infection.

Preventing Illness: Proper handwashing significantly reduces the risk of contracting common illnesses like colds, flu, and diarrhea.
Protecting Others: By washing our hands effectively, we protect vulnerable individuals such as children, the elderly, and those with weakened immune systems.
Combating Antibiotic Resistance: Reducing the spread of germs through handwashing can help decrease the overuse of antibiotics, which contributes to antibiotic resistance.

The Correct Order for Handwashing: A Step-by-Step Guide

Following the correct order for handwashing ensures that all surfaces of your hands are thoroughly cleansed, maximizing the removal of germs. Here's the recommended sequence:

Wet Your Hands: Begin by wetting your hands with clean, running water. The water temperature can be warm or cold; research suggests that water temperature doesn't significantly impact germ removal. On the flip side, using comfortable water encourages more thorough handwashing.
Apply Soap: Apply enough soap to cover all surfaces of your hands. The type of soap (liquid, bar, or foam) is less important than using it properly.
Lather Your Hands: Lather the soap by rubbing your hands together vigorously. Make sure to lather all surfaces, including:
- The palms of your hands
- The backs of your hands
- Between your fingers
- Under your fingernails
Scrub Your Hands: Continue scrubbing for at least 20 seconds. This is the most crucial step in removing germs. To ensure you scrub for the right amount of time, hum the "Happy Birthday" song twice from beginning to end.
Rinse Your Hands: Rinse your hands thoroughly under clean, running water. Make sure to remove all traces of soap.
Dry Your Hands: Dry your hands using a clean towel or air dryer. If using a towel, use a disposable paper towel if possible. If using a cloth towel, ensure it is clean and dry.
Turn Off the Faucet with a Towel (if applicable): Use a paper towel to turn off the faucet to avoid recontaminating your clean hands.

Why This Order Matters

Each step in the handwashing sequence plays a vital role in effectively removing germs:

Wetting: Water helps to loosen dirt and debris from your hands.
Soaping: Soap helps to lift germs from the skin, allowing them to be rinsed away.
Lathering and Scrubbing: This process mechanically removes germs from the skin's surface. The friction created by rubbing your hands together dislodges germs trapped in skin folds and under fingernails.
Rinsing: Rinsing washes away the soap and the germs that have been lifted from the skin.
Drying: Drying removes any remaining germs and prevents their transfer to other surfaces. Damp hands are more likely to pick up and spread germs than dry hands.

The Science Behind Handwashing

The effectiveness of handwashing lies in the science of how soap interacts with germs and the physical action of scrubbing.

How Soap Works

Soap molecules have a unique structure: one end is attracted to water (hydrophilic), and the other end is attracted to fats and oils (hydrophobic). Germs, particularly viruses like the coronavirus, have an outer layer made of lipids (fats).

When you wash your hands with soap, the hydrophobic end of the soap molecules attaches to the lipid layer of the virus. On top of that, the hydrophilic end attaches to the water. When you rinse your hands, the soap molecules, along with the virus particles attached to them, are washed away.

Soap also helps to reduce the surface tension of water, allowing it to penetrate into small crevices and lift away dirt and germs more effectively.

The Importance of Scrubbing

Scrubbing your hands is essential because it provides the mechanical action needed to dislodge germs from the skin's surface. Friction created by rubbing your hands together physically removes germs that may be trapped in skin folds, under fingernails, and around the cuticles.

The Role of Water Temperature

While water temperature is often debated, research suggests that it has a minimal impact on germ removal. Studies have shown that cold water is as effective as warm water in removing bacteria when combined with soap and proper handwashing technique.

Still, using comfortable water is crucial because it encourages people to wash their hands more thoroughly and for a longer duration.

When to Wash Your Hands

Knowing when to wash your hands is just as important as knowing how to wash them correctly. Here are some key times when handwashing is essential:

Before, during, and after preparing food: Handwashing prevents the spread of bacteria from raw foods like meat and poultry to other foods.
Before eating food: Washing your hands before eating removes germs that could cause illness.
After using the toilet: This is a critical time to wash your hands to prevent the spread of fecal bacteria.
After changing diapers or cleaning up a child who has used the toilet: Diapers and toilet training can expose you to harmful germs.
Before and after caring for someone who is sick: Washing your hands protects both you and the person you are caring for.
After blowing your nose, coughing, or sneezing: These actions can spread germs through the air, so washing your hands afterward is essential.
After touching garbage: Garbage is a breeding ground for bacteria and other germs.
After touching animals, animal feed, or animal waste: Animals can carry germs that can be harmful to humans.
Before and after treating a wound: Handwashing prevents infection of the wound.

Hand Sanitizer: An Alternative When Soap and Water Aren't Available

When soap and water are not readily available, hand sanitizer can be a useful alternative. Still, don't forget to use hand sanitizer correctly to ensure its effectiveness.

How to Use Hand Sanitizer

Choose a hand sanitizer with at least 60% alcohol: Alcohol-based hand sanitizers are more effective at killing germs than non-alcohol-based sanitizers.
Apply enough sanitizer to cover all surfaces of your hands: Use a generous amount of sanitizer to ensure complete coverage.
Rub your hands together until they are dry: Rub your hands together vigorously for at least 20 seconds, ensuring that the sanitizer reaches all areas, including between your fingers and around your fingernails.

Limitations of Hand Sanitizer

While hand sanitizer can be effective, it has some limitations:

Hand sanitizer may not be as effective when hands are visibly dirty or greasy: Soap and water are more effective at removing dirt and grime.
Hand sanitizer may not kill all types of germs: Some germs, such as norovirus and Cryptosporidium, are more resistant to hand sanitizer.
Hand sanitizer is not a substitute for handwashing: Soap and water should always be your first choice for hand hygiene.

Common Handwashing Mistakes to Avoid

Even when people intend to wash their hands properly, they often make mistakes that reduce the effectiveness of the process. Here are some common handwashing mistakes to avoid:

Not wetting hands first: Wetting your hands helps to loosen dirt and debris, making it easier for the soap to work effectively.
Not using enough soap: Using an inadequate amount of soap means that not all surfaces of your hands will be properly cleansed.
Not lathering and scrubbing for long enough: Insufficient lathering and scrubbing reduces the amount of time that soap has to kill germs.
Not cleaning between fingers and under fingernails: These areas are often missed during handwashing, providing a haven for germs.
Rinsing too quickly: Rinsing too quickly leaves soap residue on your hands, which can attract more germs.
Using a dirty towel: Drying your hands with a dirty towel can recontaminate them with germs.
Turning off the faucet with clean hands: Touching the faucet with clean hands can recontaminate them with germs picked up from the faucet handle.

Handwashing for Children

Teaching children proper handwashing techniques is essential for their health and well-being. Here are some tips for teaching kids how to wash their hands effectively:

Make it fun: Turn handwashing into a game by singing songs or using colorful soap.
Explain why it's important: Help children understand that handwashing protects them from getting sick.
Supervise young children: confirm that young children are using enough soap and scrubbing for the correct amount of time.
Lead by example: Children are more likely to adopt good handwashing habits if they see adults doing the same.

Hand Hygiene in Healthcare Settings

Hand hygiene is particularly critical in healthcare settings, where patients are more vulnerable to infection. Healthcare workers must adhere to strict hand hygiene protocols to prevent the spread of healthcare-associated infections (HAIs).

WHO's "5 Moments for Hand Hygiene"
