Billions of bacteria live on your feet, so how often should you wash them?

LOS ANGELES (KABC) -- When you jump in the shower, it's fair to say not every body part gets an equal amount of cleaning.

Your feet can be easy to overlook, but experts say that feet are just as - if not more - deserving of attention.

The soles of your feet contain 600 sweat glands per square centimeter, more than any other region of the body.

"We call those eccrine glands," said Tanya Nino, a dermatologist with Providence St. Joseph Medical Heritage Group. "When you get over-moisture, over-occlusion of the eccrine skin on the hands and feet, that's when the skin can get macerated. Macerated means it's kind of broken down."

That opens the door to the overgrowth of fungus and yeast.



Doctors say the area between the toes can get quite humid, and if you're the type to always wear closed shoes, it can get pretty ripe in there.

For example, Krystal Malhotra, a nurse, is on her feet 10 to 12 hours a day and is required to wear closed toe shoes. So shower time is when she gets to baby her feet.

"I start at the top, then I do the bottom then I go in between the toes every day," she said.

The Centers for Disease Control and Prevention recommend Americans wash their feet daily, but Nino says a daily rinse is sufficient for most people.

"Some soaps can be harsh and can strip the skin of your natural skin barrier, so I don't really advocate for soaping everything down," said Nino.



But those with poor circulation due to conditions like diabetes should pay extra attention to foot hygiene.

"If you have a cut and you don't know it, then yes, it can become an infection," she said.

Just as important as washing is to make sure your feet are completely dry to prevent bacterial growth.

Even though she doesn't have to, Malhotra said she'll continue to wash her feet daily.

"I'm so scared of getting stinky feet!" she said.
