A nasal spray made from Atlantic Ocean seawater eased children’s cold symptoms, and slowed their return, according to European researchers.
The 12-week study involved nearly 400 children between the ages of 6 and 10 who had uncomplicated cold or flu symptoms. Some children received nasal decongestants or other standard treatments, while others received a saline nasal wash that had ions and trace elements at levels comparable with those in seawater.
Children who were given the nasal spray had less stuffy and runny noses, along with fewer severe sore throats, coughs, nasal obstructions and secretions, than those given standard treatments.
Further, those who used the nasal spray missed fewer school days, were sick less often and used fewer fever-reducing drugs, decongestants and antibiotics.
The researchers are not sure why the saline solution was effective, but suggested it could be due to a mechanical clearing of mucus, or could have something to do with the trace elements in the water.
Saline nasal washes have long been used as a treatment for colds, but evidence supporting their effectiveness is scarce.
