Before you eat:
This habit is one of the more obvious, yet neglected habits. Cleaning your hands before eating is probably the most important habit to build. Germs can double every twenty minutes in food ranging from 40℉ - 140℉ (USDA). Wash your hands, whether with soap and water or with an alcohol-based hand sanitizer, before eating!
After you use the bathroom:
Again, this one is fairly straightforward. However, did you know only 19% of people wash their hands after using the toilet, globally (CDC)? Germs like e-coli, salmonella, and norovirus (Cleveland) can be particularly problematic in the bathroom, stemming from fecal matter (gross). It’s recommended you wash your hands for at least 20 seconds.
After touching an item in a public space:
This one is more geared toward the current pandemic, but can also be rather useful normally. Objects that might have been touched often, like credit card register screens, gas pumps, shopping carts, and door handles might have germs that cause sickness. Studies show that COVID-19 seems to behave like other coronaviruses, which can last on surfaces for a few hours to a couple days, depending on a number of conditions like temperature and humidity (WHO).
After sneezing, coughing, or blowing your nose:
This habit is much more pertinent because of the novel coronavirus. Since some people can remain symptom free, washing your hands after sneezing, coughing, or blowing your nose is especially important so that you don’t spread any unnecessary germs.
