The Science of Hand Washing
Information and Resources For Parents
Teaching kids about hand washing is not just important to keep them
healthier in childhood... but all through life. The sad fact is that many, many adults don't
seem to believe that hand washing is important, including the adults who
prepare our food! Middle school teacher
John Lundgren
found this out for himself when he discovered that the same guy he'd seen
earlier in the restroom -- a guy who left without washing his hands -- was about
to serve him food in the mall food court! The experience prompted him to
create his own website devoted to this important topic.
But many teachers, and parents, have had their own experience with
lapses in hand washing hygiene, including the huge absentee problem that
is generated by the unchecked spread of germs. Oftentimes the
illness that is spread is a mild to moderate form of the common cold or
the flu. But from time to time we do hear about outbreaks of much
scarier illnesses, like meningitis. And with scientists warning
about the potential for new, more serious, flu strains and strange
hybrid diseases, we owe it to the children in our care to promote the
effective and deceptively simple skill of hand washing.
How To Teach
Young Children
To Wash Their Hands
The best way to teach
anything to young children is to make if fun, make a game out of it,
and by teaching and modeling what to do through your own behavior.
Making It Fun
Try some of these...
Have the hand washing area set up for comfort -- a stool or
low wash basin.
Have fun soaps and scrubbers. (Be aware that fingernail
scrubbers can spread germs if not properly maintained and
are better suited to the home environment than classrooms.)
Put "no touch" items out of reach and out of sight.
Create an appealing environment through kid-friendly decor
like Sponge Bob or Little Mermaid.
Make It A
Game
Have child
sing a fun song while washing to help mark the time, so
he/she knows just how long to wash (15-20 seconds).
Keep a hand
washing chart and encourage the child to see many squares
he/she can fill in. (The emphasis should be positive,
never shaming -- "Look what you did, wow!")
Refer to a
printable poster, or homemade poster, that shows the proper
steps for hand washing. Make a game out of following
each step. You can approach it quiz style, "What
do we do first? ....And what's Step Two?" Or just be
silly, "Okay, first we ....dry our hands-- right? No?"
Teaching
What To Do
Keep in mind
that young children are visual and kinetic learners.
This means they learn best by seeing and doing -- rather
than just hearing.
Have your
young child watch your or another child wash hands, while
you talk about what to do.
Then have your
child do it, while you again explain the basic steps.
Don't forget
to keep it fun and simple. Don't try to cram in
all the facts at once. Start with the bare basics, and
then add different pieces of information in later
installments. (Note that 1st-3rd and 4th-6th
graders will each have higher levels of attention span and
greater tolerance for getting a lot at once.)
Small children
learn best through repetition and reinforcement. You
can follow up your first lesson with story books about germs
and hand washing; by looking at pictures of germs; by making
pictures or posters (collages are great for preschoolers who
can glue stick but not draw); and by acting out silly little
skits about getting germs on your hands, hand washing,
getting sick, and etc.
Modeling
What to Do-- And When to Do It
Always
remember that small children are impressed by what we do
(enjoy it while it lasts!), and that older children learn
more from what we do than what we say. So if you want
to teach the importance of hand washing...wash your hands!
Kids can't
always see what we do, so be sure to talk about it.
Tell a little story about when you wash your hands, about
something icky you touched and how you washed afterwards,
and don't forget to tattle on yourself once in a while.
Sometimes sharing about mistakes you've made (in a funny and
forgiving way) and talking about why you wish you'd done it
differently is more effective than pretending you do the
right thing all the time. After all, who can relate to
someone who's perfect!
Washing hands
together!
Point out or
talk about other people who wash their hands: your doctor
and dentist, people who work in restaurants, etc.
Have a
Routine
Make hand
washing a regular part of toileting, meal time, diaper
changing, and etc.
Additional Safety
Considerations
Don't forget
to put locks on bathroom cabinets that contain medicines,
cleaners, or anything else that could harm a child.
Talk to your child about why these areas are off limits and
what to do if they find anything dangerous laying about
(meds, razor, etc.).
Please
remember to talk to children about the dangers of very hot
water and to turn your water heater down! It should
never be higher than 120°F.
Note that some sources say that 130°F is safe enough, but as
you can see below, the difference between 120°F and temps
nearer to 130°F is huge, in terms of how much harm can be
done to a child. Furthermore, 120°F should be more
than sufficient to run your dishwasher and laundry.
The
following chart shows just
how dangerous hot water can
be.
Temperature Time to Cause
of Water a Bad Burn
-------------------------------------
150°F (66°C) 2 seconds
140°F (60°C) 6 seconds
125°F (52°C) 2 minutes
120°F (49°C) 10 minutes
-------------------------------------
Use soap and running water. Warm to hot water is
best.
Wet hands thoroughly and lather with soap.
Rub hands vigorously for at least 10-15 seconds as
you wash them.
Pay attention to the backs of hands, wrists, between
fingers, and under fingernails.
Rinse hands well under running water.
Dry hands with a disposable paper towel or a clean
towel. To minimise chapping (reddening, roughening
or cracking of skin) of hands, pat dry rather than
rub them. Electric hand driers may be used. If cloth
towels are used, select a fresh towel each time, or
if a roller towel is used, select a fresh portion of
towel.
Turn off the tap with the used towel.
Use skin lotion, if necessary, to prevent dry
cracked skin.
If you use skin lotion, it should be rinsed off
before preparing or handling food.
Parents should wash their hands:
·before preparing, serving food, or eating food
·after caring for a sick child (blowing their noses or wiping eyes
·after diapering a child
·after cleaning up a mess
·after helping a child with toileting
·after cleaning up spills
·after other cleaning activities
·after smoking
Handwashing No Longer Necessary?
Alan Greene MD FAAP
The days
of "wash
your hands before dinner" are (at least partially) coming to an end!
True,
many infections are spread by the hands.
True, we have been urging people to increase handwashing to prevent these
infections. True, even in hospitals people have not been following guidelines
adequately. (I was seen by a doc in an ER recently who did not wash between
examining the contagious person next to me and examining me.) But on November 9,
2001 the CDC released draft guidelines for hand hygiene in hospitals and other
healthcare settings, calling for a switch AWAY from handwashing, toward using
alcohol-based, waterless antiseptic gels on the hands (unless the hands are
visibly dirty or contaminated). When compared to soap and water, or
antibacterial soap and water, the hand
gels are MORE effective and LESS irritating or drying. They are even an
improvement over the time-honored 'surgical scrub'. They are also more
convenient and easier to get kids (and doctors) to use. The CDC recommends that
waterless antiseptic gels be kept at all patient bedsides, and that individual
pocket-size containers be carried by all healthcare personnel. I admit that we
have already made this switch in my family -- even before the studies came out

Project Handwashing, a
program of Colorado State University Extension
, is available online for free. It
includes a "script" for doing a presentation on
germs and handwashing as well as a pictorial quiz to
give the kids and some coloring pages.
