The Many Reasons to Try a Salt Water Gargle

For thousands of years, healers have used salt as a remedy and as an ingredient to ward off illnesses. Today, medical practitioners still prescribe salt water gargles to ease the discomfort of a sore throat. Although sore throat pain usually goes away within a week, a warm salt water gargle can provide temporary relief for the scratchiness and discomfort.

How it Works

Gargling with salt water not only eases throat pain, but it reduces inflammation, loosens mucus, kills bacteria, and breaks down secretions that lead to irritation. Salt water is hypertonic, meaning that it carries a higher osmotic pressure than human cell fluid. When a person gargles salt water, it draws cellular fluid to the surface, along with the virus or bacteria in the throat.

Preparing a Salt Water Gargle

A salt water gargle is an inexpensive option for treating a sore throat at home. Physicians recommend stirring one-fourth to one-half teaspoon of salt into eight ounces of warm water. Continue stirring until the salt dissolves completely. Although any type of salt works, coarser salts like kosher or sea salt dissolve faster than table or iodized salts.

What it Accomplishes

Gargling with salt water does not cure a sore throat or get rid of an infection, but it does provide pain relief while the body fights off the underlying cause of the symptoms. Ear, nose, and throat experts recommend gargling at least three to four times a day or every three hours until the pain goes away. Because salt can cause cells to dry out, it is important to drink plenty of water in addition to the gargling regimen.

Don’t Swallow the Salt Water

After gargling with salt water, doctors say it is important to spit it out. This gets rid of some of the virus or bacteria causing the discomfort. Swallowing small amounts of salt water is not usually harmful. However, larger amounts can cause changes in the body’s sodium levels and lead to dehydration and other issues, so never swallow the gargling solution.
