The wind can help people have higher intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse in 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 during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer.
