It may seem too simple, but keeping your hands clean with soap and water is one of the most important things you can do to stay healthy. That’s according to the Centers for Disease Control and Prevention (CDC), which has issued a reminder about the importance of washing hands – and backed it up with a toolkit to encourage handwashing within your community.

That and other resources are part of the CDC’s Life is Better with Clean Hands  campaign that’s designed to motivate adults to make clean hands part of their daily lives.

Why spread the word about something so basic?

The CDC says educating people about handwashing:

  • Reduces the number of people who get sick with diarrhea by 23-40% 2, 3, 6
  • Reduces diarrheal illness in people with weakened immune systems by 58%  4
  • Reduces respiratory illnesses, like colds, in the general population by 16-21% 3, 5
  • Reduces absenteeism due to gastrointestinal illness in schoolchildren by 29-57% 7

 

“Handwashing is a win for everyone, except the germs.”

 

 

Handwashing with soap removes germs from hands. This helps prevent infections because:

 

  • People frequently touch their eyes, nose, and mouth without even realizing it. Germs can get into the body through the eyes, nose and mouth and make us sick.
  • Germs from unwashed hands can get into foods and drinks while people prepare or consume them. Germs can multiply in some types of foods or drinks, under certain conditions, and make people sick.
  • Germs from unwashed hands can be transferred to other objects, like handrails, table tops, or toys, and then transferred to another person’s hands.
  • Removing germs through handwashing therefore helps prevent diarrhea and respiratory infections and may even help prevent skin and eye infections.

How to do it right

Handwashing involves five simple and effective steps (Wet, Lather, Scrub, Rinse, Dry). Regular handwashing, particularly before and after certain activities, is one of the best ways to remove germs, avoid getting sick, and prevent the spread of germs to others. It’s quick, it’s simple, and it can keep us all from getting sick.

“Handwashing is a win for everyone, except the germs,” according to the CDC.
