Many Wrongly Think Tap Water Is Safe for At-Home Medical Use


Could 11, 2022 – Whereas water out of your faucet usually is protected to drink, you shouldn’t use it for at-home medical functions like sinus rinsing, washing contact lenses, and filling respiratory gadgets. However new analysis means that many Individuals – wrongly – suppose faucet water is protected for such makes use of.

In a survey of 1,004 adults within the U.S., about one in three individuals mentioned that faucet water didn’t comprise micro organism or different dwelling organisms, and 26% mentioned water filters eliminated these microbes and thus sterilized water. Each statements are false: Faucet water might comprise some microbes, and water filters can not take away these dwelling organisms from water.

Faucet water goes by way of a multistep therapy course of that makes it protected for us to drink, and it should meet strict security requirements earlier than leaving a water therapy plant. However germs that naturally exist within the surroundings can stay.

As faucet water travels by way of miles of pipes all the way in which to your faucet, it may well decide up waterborne microbes, says Shanna Miko, DNP, of the Waterborne Illness Prevention Department on the CDC’s Nationwide Heart for Rising and Zoonotic Infectious Ailments. Bottled water is held to the identical requirements and can be not thought of sterile, she says.

Our our bodies encounter germs each day, and most wholesome individuals uncovered to these present in pipes don’t get sick. However some teams may be at the next danger for an infection, like individuals age 50 or older, infants underneath 6 months previous, present and former people who smoke, individuals with a weakened immune system, or these with diabetes, liver failure, or kidney failure.

“When we’ve got this mix of susceptible populations and utilizing [tap water] in numerous methods, like placing it in our eyes or our nasal cavity or inhaling it into our lungs, that’s the place the chance happens,” Miko says.

The CDC advises that water used for nasal rinsing and the filling of respiratory gadgets must be sterile, that means that it doesn’t have any micro organism or different dwelling organisms. Contact lenses ought to solely be washed and saved in recent contact lens resolution, and wearers ought to keep away from any water touching their lenses, which incorporates swimming and bathing.

Nonetheless, there are instances the place individuals have gotten infections attributable to misusing faucet water for medical functions, Miko says. In one extreme case, a lady died after contracting a brain-eating amoeba whereas utilizing faucet water in a nasal-flushing neti pot.

These kind of instances are uncommon, however it will be important that the general public understands the right way to “decrease their publicity to these germs at dwelling,” she says, particularly if they’re notably susceptible to an infection.

Survey Outcomes

To seize how the American public understands water sterility and the way they use faucet water at dwelling, Miko and colleagues designed a survey that they despatched to individuals ages 18 and above from Aug. 16 by way of Aug. 18, 2021. The nationwide pattern was then weighted to symbolize of the U.S. inhabitants in gender, age, area, training, race, and ethnicity.

The outcomes of the survey have been offered on Could 5, 2022, on the CDC’s annual Epidemic Intelligence Service Convention.

About 63% of individuals appropriately answered that sterile water doesn’t comprise any micro organism or different microorganisms, and two-thirds knew that faucet water may comprise these microbes. However there was a disconnect on what was protected for at-home medical use, Miko says.

“Regardless that they acknowledged that faucet water is not sterile, they nonetheless agreed that it was OK to make use of for nasal rinsing and speak to lens rinsing or storage and even in respiratory gadgets like dwelling humidifiers, just like the CPAP machines that some individuals use at nighttime,” she says.

Greater than half of individuals (62.4%) mentioned faucet water was protected for nasal rinsing, half (50.1%) mentioned it was protected for rinsing contact lenses, and 41.5% mentioned that it might be safely used for medical respirator gadgets and humidifiers.

However far fewer individuals reported truly utilizing faucet water for these duties. About one in 4 (24%) mentioned they stuffed medical respirator gadgets with faucet water, 12.7% mentioned they used faucet water for nasal rinsing, and about 9% mentioned they used it to rinse contact lenses.

The outcomes present “there’s a actually dramatic want for training of the general public referring to faucet water,” says Rachel Noble, PhD, who does analysis on water high quality and public well being on the College of North Carolina at Chapel Hill. She was not concerned within the examine.

“It’s fairly clear that most individuals know that sterile signifies that nothing is rising in your water,” she says. The confusion, she says, lies in whether or not faucet water may be safely used for medical functions.

Protected, Sterile Water

Whereas water straight out of the faucet shouldn’t be used for these procedures, boiling the water is a straightforward approach to kill any micro organism, viruses, or different microbes and make it protected for nasal rising or filling medical respiratory gadgets, Miko says. The water must be boiled for 1 minute after which left to chill.

If you happen to don’t need to boil your water, you can even buy sterile or distilled water, that are each protected for at-home medical use. The CDC’s Healthy Water site additionally has info on cleansing water at dwelling.

Whereas the survey was meant to indicate the right way to deal with water that’s for at-home medical use, Miko says that faucet water is handled and sanitized and “is supposed to be protected for ingesting, cooking, and self-care like bathing, tooth brushing, and laundry.”

Whereas most wholesome individuals won’t get sick from germs they may discover in water, the small steps of boiling it or shopping for sterilized water for at-home medical use may help stop infections, particularly in individuals at increased danger.

“We don’t need to scare individuals,” she says. “We simply need individuals to be as wholesome as they are often.”
