More than two dozen companies have developed products to protect against the risk of getting sick from exposure to dead sea salts.
And some have been able to develop new ways of preventing the spread of bacteria that can be deadly to people.
But in a study published Monday in the journal JAMA Internal Medicine, scientists from Johns Hopkins University School of Medicine, Massachusetts General Hospital and Massachusetts General University looked at the risk from the three-day exposure to seawater at the end of the year, the year after and in 2022.
The researchers said there was a “clear, albeit modest, increase” in the risk for people exposed to seawaters in 2022 compared with the year before.
They said this could be because the risk was higher because of more people who drank the contaminated seawater.
The study, which was conducted by the researchers, examined a group of people who were hospitalized in Florida in late February 2022.
It said the risk did not change significantly for those who drank seawater that had been exposed to salt water.
But the risk increased in those who had not had the exposure, the researchers said.
The risk increased for people who had consumed seawater contaminated with boric acid, a chemical found in seawater used for cooking and baking.
Boric acid is one of the most dangerous chemicals in seawaters.
It can cause kidney damage and lead to the death of the organism that creates the acid, called bicarbonate of soda.
The chemical is also found in some organic products and in some industrial processes.
But experts said there is no proof that the risk is related to drinking seawater, and there are also no proven protective measures for those exposed to it.
The Centers for Disease Control and Prevention recommends limiting your exposure to saltwater to 10 times the recommended daily limit of 7.5 milligrams of bicarbons per kilogram of body weight.
