My personal way of managing rhinitis

It's not severe, but every late autumn I suffer from a cold caused by rhinitis, almost like an annual event. A friend told me that gargling with salt water can not only help with rhinitis but also strengthen teeth. I have been gargling every morning and evening for several months. I mix about three teaspoons of salt into 1000ml of water, boil it, and then gargle. This way, I don't have to worry about cavities, and I think I can get through this fall without suffering from rhinitis. My breathing has also become easier. Stay healthy always.
