Why Nasal Irrigation May Help With a COVID Infection - Lifehacker

In a recent study, twice daily nasal irrigation was found to reduce the severity of COVID-19 symptoms.

By that logic, it makes sense that nasal irrigation can be a strategy for reducing the severity of COVID-19 symptoms.

Since a lot of the viruses that cause upper respiratory tract infections, which includes COVID-19, tend to proliferate in the sinuses, getting rid of them through nasal irrigation can help cut down on the overall viral load, which is known to help with symptom severity.

In the COVID-19 study, researchers had participants perform nasal irrigation with either a sodium bicarbonate solution or a saline solution with iodine added in, using a pressurized nasal irrigation system, where you squirt the solution into the nostrils.

For a nasal irrigation system, the options are to either use a neti pot, where you pour the solution into one nostril, or a nasal irrigation bottle, where you squirt the solution into one nostril.
