People in these states will have heart trouble after the weather changes in February or March. The weather can also influence intelligence. For example, in a 1983 study by scientists, the IQ scores （智商分数）of some college students were very high during a storm, but after the storm, their scores were low. Storms can increase intelligence. Very hot weather, on the other hand, can lower it . Students in many schools of the United States often do badly on exams in the hot months of the year(July and August). Weather also has a strong effect on people’s feeling. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel depressed（沮丧的） during cold weather.
