Handwashing: Your First Line of Defense Against Illness

Handwashing is perhaps one of the simplest yet most effective ways to prevent the spread of infectious diseases. From common colds to more serious illnesses like COVID-19, proper hand hygiene plays a crucial role in safeguarding our health and the health of those around us. In this post, we’ll explore the importance of handwashing, the proper technique, and some common misconceptions.

Why Handwashing Matters

Handwashing is our first line of defense against germs and pathogens that can cause illness. Our hands come into contact with countless surfaces throughout the day, picking up bacteria and viruses along the way. By washing our hands regularly, we can remove these harmful microbes before they have a chance to make us sick or spread to others.

Studies have shown that proper handwashing can significantly reduce the spread of infectious diseases. In fact, the Centers for Disease Control and Prevention (CDC) states that handwashing can reduce the risk of respiratory infections by 16-21% and gastrointestinal illnesses by 31%.

The Proper Technique

While most of us learned how to wash our hands as children, it’s worth revisiting the proper technique to ensure maximum effectiveness. Here’s a step-by-step guide:

1. Wet your hands with clean, running water (warm or cold) and apply soap.
2. Lather your hands by rubbing them together with the soap. Be sure to lather the backs of your hands, between your fingers, and under your nails.
3. Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
4. Rinse your hands well under clean, running water.
5. Dry your hands using a clean towel or air dry them.

It’s important to note that hand sanitizer is a convenient alternative when soap and water are not available. However, hand sanitizer is not as effective as handwashing when hands are visibly dirty or greasy, and it may not remove all types of germs.

Common Misconceptions

Despite the clear benefits of handwashing, there are some common misconceptions that persist:

1. Hot water is better than cold water: While hot water can be more comfortable to use, it’s not necessary for effective handwashing. In fact, water temperature doesn’t have a significant impact on removing germs.

2. Antibacterial soap is always better: Regular soap is just as effective as antibacterial soap at removing germs. Additionally, overuse of antibacterial products can contribute to antibiotic resistance.

3. Hand dryers are more hygienic than paper towels: While hand dryers may be more environmentally friendly, studies have shown that they can actually spread germs in the air. Paper towels are a more hygienic option for drying hands.


Handwashing is a simple yet powerful practice that can have a profound impact on our health and the health of those around us. By washing our hands regularly and properly, we can help prevent the spread of infectious diseases and promote overall well-being. So the next time you reach for the soap and water, remember: you’re not just washing your hands, you’re protecting yourself and others from illness.
