Have you ever wondered why experts insist on proper hand washing as a cornerstone of cold and flu prevention? Let’s explore the science behind this essential practice and why it’s more critical than ever as the cold and flu season approaches. 

Understanding the Germ Transmission Chain: 

Cold and flu viruses are primarily transmitted through respiratory droplets when an infected person coughs or sneezes. But they can also survive on surfaces for hours, waiting to hitch a ride on your hands. This is where proper hand washing comes into play. 

How Hand Washing Works: 

When you wash your hands with soap and water, you create a powerful chemical reaction. Soap molecules have two parts: one that attracts water (hydrophilic) and another that repels it (hydrophobic). These two parts work together to lift and remove germs from your skin. 

Why 20 Seconds Matters: 

It takes time for soap to break down the lipid (fat) layers that protect the virus. That’s why experts recommend washing for at least 20 seconds. During this time, the soap disrupts the virus’s structure, rendering it harmless. 

Proper Hand Washing: A Shield Against Infection: 

By practicing proper hand washing, you disrupt the transmission chain of cold and flu viruses. It’s not just about protecting yourself; it’s about protecting those around you, particularly vulnerable individuals like the elderly and young children.
