Make sure your glasses fit well. Diet seems to affect sinus symptoms in some people, although no medical studies really support a connection between foods and sinusitis. If you believe your symptoms are related to a food, you might try avoiding that food to see if it helps. Air pollution can make sinus symptoms much worse. Special air filters, called high-efficiency particulate air filters and electrostatic filters, can be helpful in reducing irritants inside buildings.
Some climates are worse than others for people who have chronic sinusitis.
The damp weather in northern areas is usually the worst. Changes in air pressure can also cause symptoms in some people. For example, some people with chronic sinusitis feel worse just before a rainstorm, when the air pressure is changing. Steam can be very helpful in relieving congestion. You can use steam inhalations with or without astringents such as eucalyptus, pine oil or menthol.
