5 Subtle Causes of Sinusitis That You Should Know

You come down with a nasty cold and before long it develops into an even nastier sinus infection.

Your head pounds and feels like it’s going to explode. Your first reaction is “oh, this happens every time.” But for you and the other 37 million Americans who suffer from this problem, there are many other causes of sinusitis you might not be aware of.

Swimming and Diving

Many sinus infections occur during the summer due to the chlorine in pools. Chlorine causes irritation and swelling of the nasal passages as it gets into the ears and nose. Once there is swelling, mucus gets trapped and a blockage occurs. In this moist dark environment, bacteria can grow causing an infection. It is best to avoid swimming if you have a cold or a sinus infection since can exacerbate your symptoms.

Nasal Polyps

Polyps are tiny benign growths that can interfere with the sinus passages causing blockages and swelling. Headaches are a typical symptom of polyps. Use nasal steroid sprays as treatment, and sometimes surgery may be recommended.


Besides all the other negative consequences of smoking, you can now add these. Smoking also irritates the nasal passages, lowers the body’s ability to resist infections, and causes swelling and inflammation. Smokers also experience more severe symptoms from sinusitis than non-smokers.


If you suffer with spring and fall allergies, your allergy symptoms may block sinus passages and increase sinus inflammations leading to sinusitis. In addition, allergies make the symptoms even more acute.

Bacteria and Viruses

However, if the infection is viral and usually the result of a cold, an antibiotic will not help your symptoms. Use an OTC decongestant, get a flu shot, and wash your hands frequently to avoid a viral sinus infection. Discovering the cause of the infection defines the treatment.
