Title: Understanding the Science Behind Gargling with Salt Water for Sore Throat Relief

What is the science behind gargling with salt water to relieve a sore throat?

Is it true that gargling with salt water causes swollen throat cells to shrink and feel better?

Answer:

Yes, gargling with salt water when you have a sore throat is indeed beneficial for reducing swelling and alleviating discomfort.

When you gargle with salt water, you create a hypertonic solution in your throat. This means that the salt concentration outside the cells in your swollen throat is higher than inside the cells. As a result, water moves out of the cells through a process called osmosis.

Osmosis is a biological process where water moves from an area of low solute concentration to an area of high solute concentration across a semipermeable membrane. In this case, the higher salt concentration outside the cells causes water to be drawn out of the swollen cells, leading to their shrinkage and thus relieving the soreness.

Gargling with salt water helps to reduce the swelling of the throat cells and also has antimicrobial properties that can help kill bacteria and reduce inflammation.
