WebMD Countdown: Dirtiest Things You Touch Every DayArm yourself with some soap and hand sanitizer, cause it’s a dirty world out there! These surfaces are just crawling with germs that can make you sick.185

SUBJECT: Every single day

we touch surfaces that are

crawling with germs.

And the germiest might not

be what you would expect.



For example, this has more

bacteria than this.

Now that I've got

your attention,

here are just a few

of the top sources of yuck

we come across every single day.



Did you know your kitchen sink

often contains 100,000 times

more germs than your bathroom?

One word, bleach.

Products with bleach

will keep those critters at bay.

That load of wet laundry

you just handled?

If it wasn't washed

in hot water, at least 140

degrees Fahrenheit, you could be

touching e.Coli, salmonella,

norovirus, or all kinds

of unwanted gook.



And make sure to put clothes

in the dryer right away,

or you'll need to wash again.

And you might want to wash

underwear in its own load.

Just sayin'.



Most people know

that the bathroom is a breeding

ground for germs.

But did you know a toilet flush

can spray micro droplets

of nasty water

up to eight feet away?

Eight feet.

Our suggestion?

Close the lid before you flush.

You're welcome.



And when you head out

for the day, don't forget

your hand sanitizer.

Every 60 seconds a working adult

touches 30 objects.

Your typical desk, second most

germ-laden

object after the phone.

No wonder work makes us so sick.

Solution?

Wipe it down.

And stop leaving crumbs

everywhere.

They make happy homes

for all kinds of bacteria.

Going out to lunch?

Well, cash is king when it comes

to bacteria.



The average dollar bill may have

up to-- get this-- 3,000 types

of bad bugs.

Consider leaving your money

in the bank and use your debit

card instead.

There's a good chance it has

less germs.



Going to hit the gym?

Remember, health club is just

an expression.

Yoga mats, cardio equipment,

and weights can sport lots

of germs including the MRSA

strain of the staphylococcus

bacteria, which is hard to say,

hard to beat even

with antibiotics.

Make sure to wipe down

the equipment before and after

you use it, and wash your hands.



Truth is, we haven't even

scratched the surface of all

the places germs linger.

But fret not.

Every day millions of us touch

millions of things and all

the germs they carry.

Most of the time we feel fine.

And with a little common sense,

you can stay that way.



It's pretty simple.

Wash your hands.

Yeah, I see you nodding,

but it's been shown that only 5%

of us are doing it right.

Guys, you're especially

bad at it.

Hot water, soap, scrub

for a full 20 seconds.

Then rinse, dry

on a clean towel,

and repeat a lot.



Do that, and those germs don't

stand a chance.

Most people get at least 2 colds a year. You might also be one of the 1 in 5 Americans who come down with the flu.

But if you take the right steps, you can beat those odds and make this cold and flu season different.

Do these 8 things to avoid the bugs that bring you down. Keep your sick days for when you might need them more.

You’re most likely to come down with a cold or flu between September and May. So be extra careful during those months, especially if:

  • You’re older than 65
  • You have an ongoing health condition (like asthma, diabetes, heart disease, or HIV/AIDS)
  • You take any medicine that affects your immune system
  • You’re around children younger than 2

The flu virus hits these groups hardest.

Time your flu vaccination to make it more effective. It will take two weeks for the protection to start. So get vaccinated in the early fall, before flu season begins.

The vaccine won’t stop you from catching colds, but it guards against the flu strains that experts expect to be common that year. It can also make your symptoms of the flu milder if you do get sick.

Cold and flu germs pass through the air from person to person.

When a sick person coughs, sneezes, or talks, tiny drops of mucus hit the air. You can take them in through your mouth or nose.

How far away should you stay from someone who's sick? Those droplets can spread out to about 6 feet. So, keep your distance, if you can.

People are most contagious when they first have symptoms like a runny nose, cough, or body aches.

You wouldn’t share a tissue with someone, but most of us forget that bathroom towels harbor germs too.

When someone in your home has the flu, put out an extra hand towel for others to use. Or, use paper towels.

If the air in your home or workplace is very dry, flu germs will stick around longer. Run a humidifier to make it harder for illness to spread. The moist air causes airborne germs to drop to the ground where they’re less likely to infect you.

Flu germs can live on hard surfaces like doorknobs and keyboards for up to 8 hours. Some viruses that cause the common cold can survive on surfaces -- even ones that have been cleaned -- for months. If you touch something that a sick person has coughed or sneezed on and then put your fingers near your eyes, nose, or mouth, you’re likely to get sick too.

Wash those bugs right off of your hands. Use warm water and soap, and scrub your hands for at least 20 seconds.

This is especially important after you’ve been in a crowded area like a school, shopping center, or office where you could have come into contact with someone who’s sick.

If soap and water aren’t available, use an alcohol-based hand rub.

Get a flu shot each season to help prevent you from contracting the virus.

Take care of yourself every day to help your body fight off cold and flu germs. You’ll want to get enough rest, to exercise, and to stay at a healthy weight.

Stick to a diet that’s high in fruits, vegetables, and whole grains. If you drink alcohol, limit it to small amounts. If you smoke, now would be a great time to quit because smoking can make flu and cold symptoms worse.
