A new study has found that most Americans think it's OK to put tap water in medical devices such as humidifiers and neti pots, but experts say this is unsafe.
The journal Emerging Infectious Diseases found in a survey published earlier this month that 50 percent of respondents said it was OK to use tap water for nasal rinsing. However, because tap water is not sterile, this practice can lead to serious and sometimes deadly brain infections.
"If you think about how we smell, those nerves go directly from the top of our nose up into our brain," Dr. Kara Wada, an allergist and immunologist with the University of Ohio, told Cheddar News. “In some instances, that might be a direct conduit for infection."
Some easy ways to stay safe, Wada explained, include buying distilled water from a grocery store. For nasal rinsing, she advised buying premixed saline solution from a medical supplier.
You can also always boil your tap water and make your own salt-water solution.
"It needs to boil for about one minute," said Wada. "If you're at a higher elevation, that will need to be extended to about three minutes."
She added: "I wouldn't get too scared, but I would also just take these extra steps to ensure that you are doing this safely."
Volunteers worked frantically on a second day Wednesday to save dozens of pilot whales that have stranded themselves on a beach in Western Australia, but more than 50 have already died.
The water temperature on the tip of Florida hit hot tub levels, exceeding 100 degrees (37.8 degrees Celsius) two days in a row. And meteorologists say that could potentially be the hottest seawater ever measured, although there are some issues with the reading.
Plastic-Free July is being observed to highlight the use of plastic and its effects. Cheddar News' Michelle Castillo gave up using single-use plastic for the day and spoke with Kathyrn Kellogg, founder of Going Zero Waste, to get her take.
