This week is National Handwashing Awareness Week. This special week (always the first full week in December) focuses on the value of the simple but important act of
washing your hands. According to the
Centers for Disease Control and Prevention,
"the most important thing you can do to keep from getting sick is to
wash your hands." Here are some interesting statistics for you about handwashing:
- 2/3 of adults in the US wash hands after using the bathroom.
- 1 in 4 adults don’t wash hands after changing diapers.
- Less than 1/2 of Americans wash hands after cleaning up after pets.
- 1 in 3 wash hands after sneezing/coughing.
- Less than 1 in 5 wash hands after touching money.
- 1 in 3 E.coli occurrences is caused from not washing hands before handling food.
This week, take some time to talk with your children about the importance of hand washing. You can even introduce them to
Henry the Hand, Champion Handwasher...the
spokesperson for National Handwashing Awareness Week. Henry has a site
with lots of information about keeping your hands germ free. Check out
Henry's site

Here is a simple activity that will help to explain the importance of washing your hands.
Here’s What You Need
Here’s What You DoPlace
a few drops of the Glo Germ on your palm rub your hands together. Make
sure you rub the liquid all over your hands (e.g. the back of your
hands, around fingernails, etc.). Turn off all of the lights and shine
the Ultra Violet lamp on your hands. They should be glowing in the UV
light. The Glo Germ simulates germs on your hands. Now, it is time to
get rid of all of those germs with a good old fashion hand washing!
If you want to clean your hands, soap and water is the best thing to use. Follow these steps:
- Get a paper towel and set it next to the faucet. You will need it in a little while.
- Turn on the water. Check to make sure it isn’t too hot.
- Wet your hands, grab the soap, and start scrubbing and making suds.
- Scrub for the length of time that it takes to sing your ABC's
- Rinse hands.
- Grab the paper towel and use it to turn off the faucet (do not touch faucet with clean hands).
After
you have washed your hands, use the UV lamp to check them. You
shouldn’t see any glowing areas on your hands. Usually, people forget to
wash the back of their hands, under their finger nails, and between
their fingers. If you missed any of these areas, don’t feel bad. Head
back to the sink and wash your hands again. Just make sure you pay
special attention to those areas this time!
Here’s What You Do (if you don’t have Glo Germ)Use
a spray bottle filled with clean water. Spray water on your hands. This
water represents the germs that come out of your mouths when you cough
or sneeze. Now, touch an object (e.g. your shirt, a table, the doorknob)
or person. What happened to the object or person you touched? Is the
object or person damp? What happened? What would happen if a friend or
family member touched the object or person in the same place that you
touched? Germs are spread in the same way that the water was spread from
you to the object or person. The best way to stop germs from spreading
is to keep your hands clean with warm water and soap!
Things to Remember:
- Germs are everywhere.
- Germs are so small that you can’t see them.
- Germs can make you sick.
- You can get rid of germs by washing your hands.
- When to Wash Your Hands: after using the toilet, before eating or touching food, after playing with animals.
The Science of SoapSoap is a
surfactant.
Basically, it makes the water wetter. If you were to look very closely at a soap molecule, you would see something that looks like a big head with a long tail. The head is
hydrophilic or
water loving. This means that it really loves to link up with water molecules. The tail of the water molecule is
hydrophobic or
water fearing. Instead of attaching to water, the tail would rather link up with oils and grease. Generally, oil and water don't really mix with each other. By linking to the oil and grease as well as the water, soap helps water to wash away the oil, grease, dirt, and germs on our skin. As the water carries away the dirt, it also kills and
carries away the germs that can make you sick.
Wondershop Fast Fact: Germs, Germs, Germs
- Until
the 1860’s, people didn’t know about germs. They also didn’t know that
cleaning cuts and keeping them covered was a good way to prevent
infections. Doctors didn’t even wash their hands before operating. Ignaz Semmelweis figured out that washing hands prevented sickness in the 1840’s, but didn’t have a way to explain why. Joseph Lister
is recognized by many to be the first surgeon to clean instruments and
his hands with antiseptic chemicals that kill germs. However, there is
evidence that other cultures may have understood the value of
antiseptics prior to Lister's discovery. In 1879, for example, one
British traveler, R.W. Felkin, witnessed cesarean section performed by
Ugandans. The healer used banana wine to semi-intoxicate the woman and
to cleanse his hands and her abdomen prior to surgery.
- Medical
workers today wear gloves to protect themselves from germs. Medical
workers also wear masks over their nose and mouth so they don’t breathe
germs on their patients.
