    Different weather makes people feel different. It influences health, intelligence (智力) and feelings. In

August, it is very hot and wet in the southern part of the United States. People there have heart trouble and

other kinds of health problems during this month. In the northeast and the middle west, it is very hot

sometimes and very cold sometimes. People in these states have more heart trouble after the weather changes

in February or March.

    The weather can also influence intelligence. For example, in a 1983 study by scientists showed that the

IQ of a group of students was very high when a very strong wind came, but after the strong wind, their IQ

was 10% lower. The wind can help people have more intelligence. Very hot weather, on the other hand, can

make it lower. Students in many schools of the United States often do worse on exams in the hot months of

the year (July and August). 

    Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They

usually feel cold these months. They might feel unhappy during cold weather. But big people may have a hard

time in hot summer. At about 18℃, people become stronger.

    Low air pressure (气压) may make people forgetful. People leave more bags on buses and in shops on

low-pressure days. There is "good weather" for work and health. People feel best at a temperature of about

18℃.

    Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather's fault.
