Rinsing your mouth with salt water when you have Covid can reduce your chance of ending up in hospital.
In a study presented last week, researchers measured the effect of gargling and rinsing the nose with a saline solution on symptoms and hospitalization rates in Covid patients.
They found that hospitalization rates for people who gargled or rinsed their nose with salt water were up to 40 percent lower than those who did not.
Dr. Jimmy Espinoza, study author and professor of obstetrics, gynecology and reproductive services at the University of Texas, said the goal was to see if gargling and nasal irrigation could improve respiratory symptoms associated with Covid.
Between 2020 and 2022, the team evaluated 9,398 adults between the ages of 18 and 65 who had tested positive for Covid via a PCR test. Of these, 58 were chosen to follow either a low-dose or high-dose saline regimen mixed with warm water.
The control group that was not instructed to gargle with salt water or nasal irrigation had a hospitalization rate of 58.8 percent.

They did not explain why the saline regimens resulted in fewer hospitalizations, but Rubin said that gargling and rinsing may help clear the virus from the sinuses and reduce the chance of it entering the lungs, which can result in pneumonia. a leading cause of hospitalization.
It is unclear whether gargling and nasal irrigation would have the same effect in mostly vaccinated patients, the researchers said.
The study was presented last week at the ACAAI Annual Meeting in Anaheim, California. /DailyMail
