Gargling with salt water is indeed a well-established home remedy for sore throat, and it is supported by both anecdotal evidence and some clinical observations. The mechanism behind this practice involves several beneficial effects that can help alleviate the discomfort associated with a sore throat.

Mechanisms of Action

1. Osmotic Effect: Salt water creates a hypertonic solution that can draw excess fluid out of swollen tissues in the throat, potentially reducing inflammation and swelling. This can provide temporary relief from pain and discomfort.

2. Antimicrobial Properties: Salt has mild antimicrobial properties, which may help reduce the bacterial load in the throat. While it is not a substitute for antibiotics in cases of bacterial infections like strep throat, it can help in cases of viral infections or mild bacterial irritation.

3. Mucus Clearance: Gargling can help loosen mucus and debris in the throat, making it easier to expel. This can be particularly helpful if post-nasal drip is contributing to your sore throat.

4. Soothing Effect: The warm salt water can provide a soothing sensation, which may help ease the pain temporarily.

Practical Guidance

Given your current situation, where you suspect your sore throat may be related to dietary choices (such as consuming too many cookies), gargling with salt water could be a beneficial and easy remedy to try. Here’s how to do it effectively:

1. Prepare the Solution: Mix about 1/2 to 1 teaspoon of salt in a glass of warm water (8 ounces). Ensure the water is warm but not hot, as extreme temperatures can further irritate the throat.

2. Gargling Technique: Take a sip of the solution, tilt your head back slightly, and gargle for about 30 seconds before spitting it out. Repeat this process several times, ideally 2-3 times a day.

3. Hydration: Ensure you stay well-hydrated by drinking plenty of fluids, as this can also help soothe your throat and support your overall recovery.

Considerations

While gargling with salt water can provide symptomatic relief, it is important to monitor your symptoms. If your sore throat persists for more than a few days, worsens, or is accompanied by other concerning symptoms (such as high fever, difficulty swallowing, or swollen lymph nodes), it would be prudent to consult a healthcare professional for further evaluation.

In summary, your dad’s advice about salt water is not just an old wives’ tale; it can be a practical and effective home remedy for soothing a sore throat. Give it a try, and hopefully, you’ll find some relief!
