Sore throat can disrupt your entire day—whether it’s caused by a cold, flu, allergies, or dry air. Among the simplest, safest, and most effective home remedies is the salt water gargle. It’s more than folklore: this technique is clinically supported, doctor-recommended, and globally practiced for relieving throat irritation, reducing inflammation, and flushing out microbes.
🌊 How Salt Water Gargling Works
Salt creates a hypertonic environment, pulling excess fluid from swollen tissues via osmosis. It:
👊 Reduces inflammation
🦠 Flushes out bacteria, viruses, and allergens
💧 Moisturizes dry throat lining
🚫 Prevents upper respiratory infections
🧬 Scientific Proof:
A 2019 study in American Journal of Preventive Medicine showed regular salt water gargling reduced respiratory infection risk by 40%.
Another 2021 RCT in Journal of Family Medicine confirmed faster recovery and pain relief in sore throat patients using salt water gargles 3× daily.
