Handwashing is a cornerstone of personal and household hygiene, particularly in winter when viruses like influenza and norovirus are rampant. According to the Centers for Disease Control and Prevention (CDC), washing hands with soap and water removes germs, dirt, and chemicals more effectively than sanitizer alone. Soap molecules disrupt the lipid membranes of many viruses, allowing them to be washed away, while hand sanitizers with at least 60% alcohol can inactivate many pathogens but are less effective against certain germs and do not remove dirt or chemicals.

The CDC recommends washing hands for at least 20 seconds, especially after coughing, sneezing, using the restroom, or touching frequently handled surfaces. Focus on scrubbing all parts of the hands, including the backs, between fingers, and under nails. For times when soap and water are unavailable, use an alcohol-based hand sanitizer, but remember that sanitizers don’t eliminate all types of germs. Frequent and thorough handwashing significantly reduces the risk of transmitting illnesses in the home during winter. For more guidance, visit the CDC’s handwashing science resource.
