How Often Should You Change Your Underwear, Bath Towels, and Toothbrushes?

We all have personal items we use every day and we can not live without them. Through the bed sheets to our pajamas to our toothbrushes to our towels and even to our underwear, we use these exact things daily. But the majority of us overlook the fact these things also harbor bacteria and we need to change them as frequently as possible.

Perhaps you have heard about the above information, but the question is: when do you really have to change these items to avoid getting sick?


Here’s a disgusting fact: about 7% of women and 25% of men don’t change their underwear for two days straight. Unfortunately, this can cause urinary tract infections, blood infections, and even pneumonia due to the microbes the underwear contains. There are no exceptions; you have to change your underwear DAILY. Make sure you also replace them each year.


Regarding to a study, a lot of men who are 18 to 30 years old wear their pajamas for 13 nights. Amazingly, women wear theirs for 17 evenings straight. You will need to change once you’ve worn yours double. Or you can simply change and clean them at least once a week because:

  • People naturally shed skin cells and since we wear pajamas next to the skin, microorganisms fill them vastly with high speed.
  • The microorganisms are usually harmless, however they can cause problems if indeed they reach wrong places in the body.
  • Dirty pajamas can cause UTI and E. coli when bacterias enter the body.
  • In some instances, UTI due to bacteria can result in cystitis.

towelsYou almost certainly haven’t washed your bath towels, but this is a negative practice that you should be rid of. These towels absorb your skin cells which you have shed, combined with the natural bacterias from the body. Due to the warm and wet environment, bacterias easily thrive, so be sure you change towels after each THREE USES. Posting towels is also a large no-no because this can lead to:

  • Cold sores
  • Athlete’s foot
  • Staphylococcus aureus that can cause infections of the skin

Bed Sheets

According to a recent poll, less than 35% of us leave the bed sheets unwashed for two weeks. Sadly, this is a poor practice since mattresses contain the human being cells that we have discarded, along with our sweat and bacteria. So how often should you change your linens? Experts say you should do this every week. Also, every morning, open your windows after pulling back the duvet. This can help remove the captured humidity and wetness.


A couple of about 10 million germs in your toothbrush typically. These bacteria can be anything from flu trojan to bacteria and could even harbor fatal infections like Hepatitis C. It really is smart to change your toothbrush every 90 days or soon after you get unwell.
