【答案解析】[解析] 10-12 Sneezing fits can strike in any season. But are they caused by allergies, viruses, bacteria or something else? Ask your nose—it always knows. Consider the circumstances surrounding your sneezing episodes. Did your local weather forecaster issue a pollen warning? Did you recently clean the house, mow the lawn or snuggle your new kitten? If so, you may have allergies. Did you stare into oncoming car headlights or blast your stereo? Bright light and loud noises stimulate the cells in the nose that release histamines, which trigger sneezing. Note how your nose and eyes feel. If sneezing is accompanied by itching, it's most likely an allergy. If you have a sore throat or runny nose, but no itching, it's probably an infection. Evaluate the frequency and duration of your sneezes. Short bursts of sneezing suggest infection. Powerful, daily sneezing episodes are typical of allergies. Multiple, early-morning sneezes may mean you're allergic to dust mites. Figure out if your entire nose is in the action, sneezes from allergies or infection usually come out of both nostrils. If only one nostril is involved, it could signal a deviated septum or a nasal polyp, see your doctor for a checkup. If all else fails, ask yourself if you might be pregnant. The hormones associated with pregnancy can cause sneezing. Pregnant women also often have rhinitis a runny nose and may sneeze as a result. 10.
