What are the consequences of different weather changes on people?

The winter in the north is long and cold, the climate is dry, and there is little wind and rain. This harsh and changeable environment makes northerners like to drink hard liquor, which makes them irritable and emotional. Their mood is cheerful and straightforward, their movements are rough, and they are insensitive to the outside world. There have been many founding monarchs, generals, warriors and savage heroes in history.

The influence of rainfall on people's mood is also relatively direct and obvious. Continuous rainy days make people feel depressed and depressed. Before the storm comes, people will feel a sense of excitement, which is related to the large increase of charged particles in the air. Lightning increases negative ions and makes people feel happy. It is drizzling in winter and spring in the south of the Yangtze River, with an annual rainfall of 800 mm to 1700 mm, which makes Jiangnan people sentimental and plump.

Air pressure can also affect people. In the weather where the air pressure suddenly drops, people's mood will be restless, impulsive and irritable, and abnormal behavior will occur. After studying a large number of automobile accidents, Canadian scientists found that most accidents occurred when the air pressure dropped. Some studies even show that a sudden increase in temperature in low-pressure areas will lead to an increase in violence.
