Who Is Prone to Sinus Problems?
People who have very narrow sinus cavities can have impaired drainage so that any swelling or infection creates a blockage that causes sinus infection.
If your sinus passageways are narrow then what happens is if you get any kind of inflammation whether it’s from pollution, allergy or infection or just dry air, the sinus shuts down, the mucus sits there and pools, and you start feeling the sinus problem.
Those with allergies and food sensitivities are predisposed to sinus infections since the offending allergens like cigarette smoke, pollution or food triggers enter the body and turn on cells, make proteins and release chemicals that cause the sinuses to swell, leading to infection.
Also, those with lowered immunity (as when you’ve had a cold) may be at higher risk for developing sinusitis. Since your immune system helps fight infection, when its lowered from any cause they can’t keep bacteria or viruses away. Then bacteria have an easier time coming in and causing a full-fledged infection.
