Why a Simple 20-Second Handwash is Your Best Defense Against Illness

We all wash our hands several times a day without giving it much thought. It feels like a simple, routine part of daily life that we do on autopilot.

However, this small habit plays a massive role in protecting your overall health and wellness. When you understand how germs spread, you can protect yourself and your loved ones from many common illnesses.

Why is frequent handwashing so important?

Simply put, handwashing is one of the easiest and most effective ways to stop illnesses from spreading. Germs are everywhere in our environment, from kitchen counters and door handles to public transportation and shopping carts.

Your body has a strong immune system designed to fight off many of these microscopic invaders. Even so, certain germs can easily overpower your defenses and make you sick. That is why proper handwashing makes such a huge difference.

Think of germs like tiny invisible passengers looking for a ride. Your hands act as their vehicle as you move through your day. When you touch a contaminated surface, these tiny passengers hitch a ride on your skin.

When you touch your eyes, nose, or mouth later on, those germs enter your body and cause infections. Studies show that proper handwashing can prevent about one-third of stomach bugs and diarrhea-related illnesses, and roughly one-fifth of respiratory infections.

When you wash your hands correctly, you wash those germs down the drain instead of letting them reach their destination. Even if some germs try to hold on, scrubbing with soap washes away the vast majority of them. Staying healthy yourself also stops you from passing those germs to your family and friends.

How long should you wash your hands?

This is a very common point of confusion for many people. You need to scrub your hands with soap for at least 20 seconds to clean them thoroughly. Many people make the mistake of splashing water on their hands and rushing away in two seconds.

Twenty seconds might feel like a very short time when you look at a clock, but it is longer than you think when you actually count it out. If you time yourself, you will realize how thorough you need to be.

A great trick is to sing the "Happy Birthday" song quietly to yourself two times while you scrub. That takes right around 20 seconds.

Once you practice this timing a few times, it will become a natural habit. That extra time ensures that stubborn germs get washed completely away.

What are the correct steps for handwashing?

Think about what you do first when you wash your hands. Do you grab the soap right away? If so, you might be missing a crucial step. You should always wet your hands with clean running water first.

Water helps lather the soap and lets it lift away dirt and germs smoothly. Follow these simple steps every time you wash:

1. Wet your hands: Use clean, running tap water, whether it is cold or warm. Turn off the faucet after wetting your hands to save water while you scrub.

2. Apply soap: Put enough soap on your hands and rub them together to create a rich lather. Scrub for at least 20 seconds. Make sure you cover your wrists, the backs of your hands, between your fingers, and underneath your fingernails. Scrubbing loosens the germs and dirt trapped on your skin.

3. Rinse thoroughly: Turn the faucet back on and rinse your hands under running water to wash away all the soap, loosened germs, and dirt.

4. Turn off the faucet: Your hands are now clean. Use your elbow or a clean paper towel to turn off the faucet so you do not transfer new germs back onto your skin.

5. Dry your hands: Dry your hands completely using a clean paper towel or a fresh cloth towel. Some people like to shake their hands dry in the air, but research shows that wet hands spread germs much easier than dry hands. Drying your hands properly is essential.

When do you definitely need to wash your hands?

You interact with countless objects at home, school, and work throughout the day. With a busy schedule, it is easy to forget when you should pause to wash your hands. Let us review the key moments when handwashing is an absolute must.

When handling food and drinks:.

Food goes straight into your body, making it a very direct highway for germs to enter your digestive tract. Always wash your hands in these situations:

• Before eating any meal or snack, especially when eating with your fingers.
• Before and after preparing or cooking food in the kitchen.
• Right after handling raw meat, poultry, or seafood, before touching anything else like spice jars or refrigerator handles.
• After handling garbage, compost bins, or waste materials.
• After wiping down kitchen counters and cleaning surfaces to remove harsh cleaning chemicals from your skin.

After touching animals:.

Even our beloved pets can carry germs that make us sick. Make sure to wash your hands:

• After petting dogs, cats, or other animals, especially if you are working in the kitchen or cooking food.
• After handling pet food, treats, or animal toys.
• After interacting with animals outside your home or visiting a petting zoo.
• After cleaning animal cages, litter boxes, or bedding areas.

When caring for others:.

If you take care of young children, elderly family members, or sick people, you face a higher risk of catching their illnesses. Protect yourself by washing your hands:

• After caring for anyone who is sick with a fever, cold, or stomach bug.
• After changing diapers or helping a child use the bathroom.
• After helping someone clean up or wash after using the toilet.

After exposure to body fluids:.

Body fluids carry high concentrations of germs and infectious agents. Clean your hands promptly after these events:

• After using the toilet or restroom facilities.
• After blowing your nose, coughing, or sneezing into your hands.
• After wiping away nasal secretions from a cold or flu.
• After cleaning up vomit, diarrhea, or waste materials.
• Before and after cleaning or bandaging a cut, scrape, or wound.

Special situations:.

Life cannot be rigidly scheduled, but certain public environments require extra hygiene care:

• Before putting in or taking out contact lenses. Always use soap and water for this task to protect your eyes.
• After touching shared office equipment like computer keyboards, mice, and phones.
• After touching high-traffic public surfaces like elevator buttons, door handles, and handrails.
• When you arrive home after visiting crowded public places or spending time outdoors.
• Whenever your workplace health and safety guidelines require you to sanitize your hands.

If you have any specific health concerns about your hygiene routine, consult your doctor for personalized advice.

Do you need to use antibacterial soap?

No. Any regular bar soap or liquid soap works wonderfully to remove germs and dirt. Studies show that antibacterial soaps do not offer any extra health benefits compared to regular soap and water for everyday use.

doctors may follow different clinical guidelines in specialized hospital settings, but ordinary soap is more than enough for everyday home hygiene.

Can you use body wash to wash your hands?

Yes, you can. Any soapy cleanser helps break down oils and lift germs away from your skin. Just make sure you follow the proper 20-second scrubbing and rinsing steps.

Keep in mind that some body washes contain strong perfumes that may leave a lingering scent on your hands, but they still get the job done.

Can you use a hand sanitizer instead of washing your hands?

It depends entirely on the situation. Handwashing and hand sanitizers work in slightly different ways. Soap and water physically wash away dirt, chemicals, and germs from your skin. This alcohol-based hand sanitizers kill many types of germs on contact.

Washing your hands with soap and water is always the best choice whenever possible because soap is superior in these specific situations:

• When removing harmful digestive viruses like Norovirus and bacterial spores like C. diff.
• When removing dangerous chemicals, pesticides, and heavy metals from your skin.
• When your hands are heavily soiled, greasy, or dirty from outdoor work, gardening, or camping.

However, hand sanitizers are extremely useful in other scenarios:

• When visiting a hospital or nursing home where sanitizing stations are placed at entrances. (Note: If visiting someone with a C. diff infection, use soap and water instead).
• When you do not have access to a sink and running water while traveling. (Wash your hands with soap as soon as you find a restroom).
• When helping children clean their hands on the go. Children often have sticky hands, so soap and water are best when they are very dirty. Always supervise children when they use hand sanitizer because swallowing it can be dangerous. Keep bottles safely stored away from small children.

When buying a hand sanitizer, check the label to make sure it contains at least 60% Ethyl Alcohol or 70% Isopropyl Alcohol. This concentration is required to destroy viruses like COVID-19 effectively.

Can washing your hands too much be dangerous?

As the saying goes, too much of a good thing can cause problems. While washing your hands when needed is vital, washing them excessively throughout the day can lead to skin irritation:

• Frequent washing strips away your skin's natural oils and healthy protective bacteria.
• Your skin can become dry, cracked, and rough, creating tiny openings where germs can enter your body more easily.
• People with sensitive skin conditions like eczema may experience flare-ups.
• You may develop a skin irritation known as irritant contact dermatitis.

If your job requires you to wash your hands often, apply a gentle moisturizer or hand cream regularly to keep your skin soft and protected. You can also talk to your doctor or dermatologist for advice on keeping your skin healthy.
