Weather can influence people’s intelligence. A report in 1983 showed that 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. That wind could help people have higher intelligence. Very hot weather, on the other hand, can make it lower. A recent report shows that students in many schools of the US often get lower marks 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 might feel unhappy during cold days. But fat people may have a hard time in hot summer.

Low air pressure may make people forgetful. People leave more bags on buses and in shops on low-pressure days. People feel best at a temperature of about 18℃.

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