Most nasal problems are the result of bacteria and viruses as well as other pollutants in the environment around us. In fact, more than 90% of infection causing bacteria enter the body through the nose and thrive in the nasal passages. Nasal problems, such as congestion and post nasal drip, can lead to ear, sinus, and upper respiratory infection. Nasal problems are also associated with headache, sore throat, and other unpleasant ailments.

The nose, ears, sinuses and throat form an interconnected whole. The sinuses and nasal passages produce mucous that acts as a lubricant and moisturiser for delicate tissue of the upper respiratory system. When viruses and other pollutants enter the nose, the body reacts by sending white blood cells to the lining of the nose and produces mucous to wash away irritants. Unfortunately, congestion, swelling of nasal passages, and other nasal problems often result. As we blow our nose, cough, and swallow phlegm, bacteria are forced into the ears, sinuses and throat.

Nasal problems can be avoided or at least reduced by regularly using a nasal wash. Most of us wouldn't go a day without washing our hands, at least a few times, but do nothing to flush away the harmful bacteria that lead to nasal problems. Saline nasal sprays are an excellent remedy for daily nasal cleansing. Although they moisturise and keep the nose healthy, saline nasal sprays, alone, do little to combat bacterial and viral growth in nasal passages.
