Do what you can to avoid exposure to colds and flu. Whenever possible, take more time to rest when you feel something “coming on.”
Wash your hands often, especially during cold and flu season.
As much as possible, stay away from infected people.
Follow these standbys for beating the “bugs”: eat balanced meals, exercise regularly, and get plenty of sleep.
First find out what substances you’re allergic to. Then take steps to minimize exposure to allergens or irritants in the air such as dust, pollution, and pollen.
Wear a mask when you clean, or consider hiring a housecleaner to help minimize your exposure to dust.
Sit in the nonsmoking sections of restaurants.
Avoid the outdoors during peak pollution hours such as rush hour.
Keep an air conditioner on during allergy season and clean its filter regularly.
Keeping your sinuses moist makes your mucus thinner, allowing your sinuses to drain better. This, in turn, helps prevent infection. Ask your doctor about these suggestions:
Use a humidifier, regularly cleaning out any mold or mildew in the reservoir.
Drink several glasses of water a day.
Avoid drying substances such as alcohol and coffee.
Avoid smoke, which dries out sinus linings.
Use saltwater rinses.
