Hand Washing vs. Hand Sanitizer: Which Is More Effective Against the Coronavirus?

The ongoing pandemic has highlighted the importance of proper hand hygiene in preventing the spread of the coronavirus. While both hand washing and hand sanitizers are effective, there is often debate over which method is more beneficial. This article will delve into the efficacy of each method, providing a comprehensive guide to help you protect yourself and your loved ones.

Understanding the Efficacy of Hand Sanitizers

Hand sanitizers, which contain at least 60% alcohol, are widely used for their convenience and effectiveness. According to numerous studies, hand sanitizers are highly effective if used correctly. Alcohol-based hand sanitizers work by breaking down the lipids in the virus's outer layer, rendering it inactive. While they are most effective at trapping oil layers, they require only 15 to 30 seconds to work. This is significantly less time than the 20 seconds recommended for hand washing, making them a quick fix in situations where soap and water are not readily available.

Effectiveness of Anti-Microbial Soaps

Anti-microbial soaps, which contain ingredients like benzalkonium chloride, are designed to remain effective for longer periods on the skin. These soaps bind with the oils on your skin and can be effective for more than 30 minutes. While anti-microbial soaps may seem like a more convenient option, common sense dictates that hand washing with soap and water is by far more effective. This is because hand washing physically removes and rinses away a broader range of pathogens, especially those that are difficult for hand sanitizers to eliminate.

Proper Hand Washing Techniques

Proper hand washing involves a detailed process that can be summarized in the following steps:

Start by wetting your hands with clean running water. Apply liquid soap (not gel) and lather well. Rub your hands together vigorously for at least 20 seconds, ensuring you cover all surfaces, including the backs of your hands, between your fingers, and under your nails. Rinse your hands thoroughly under running water. Dry your hands completely using a clean towel or air dryer.

By following these steps, you can effectively remove a wide variety of pathogens that may be present on your hands. It is crucial to use enough soap and thoroughly rinse your hands to ensure all residue is removed.

Benefits of Using Hand Sanitizer

While hand sanitizer is not as effective as hand washing, it is still a valuable alternative when hand washing is not possible. Hand sanitizers are especially helpful in public spaces and situations where soap and water are unavailable. The key to using hand sanitizer effectively is to apply enough product and rub it into your hands thoroughly until it is completely dry. This process should take at least 15 to 30 seconds, ensuring all germs are killed.

The Impact of Proper Hand Hygiene on Health

Proper hand hygiene can significantly reduce the risk of contracting and spreading infections. Studies have shown that the regular use of hand sanitizers can reduce the number of harmful bacteria and viruses on the skin by up to 97%. In addition, using hand sanitizer four to five times a day has been linked to a 67% reduction in sickness.

Conclusion: A Balanced Approach

In conclusion, while both hand washing and hand sanitizers are important tools in preventing the spread of the coronavirus, hand washing remains the gold standard. However, hand sanitizers can be a valuable supplement when hand washing is not feasible. By combining these two methods, you can create a comprehensive hand hygiene routine that effectively protects you and your community.
