    Are you happy most of the time? Or do you easily get angry sometimes? Everyone has a different temperament(脾气). It’s usually believed that both genes(基因）and environment may influence people’s temperament in different ways. Scientists have found that the season of the birth also plays a role.

Scientists from Budapest, Hungary, studied 400 university students. In the study, the students needed to finish some questions to know which of four kinds of temperament they most had. From the questions, scientists found that the students always answered something like “my mood often changes for no reason” and “I love to deal with new projects. even if it is risky”. These answers were then connected with their birthdays.

They discovered that people born in summer easily change between sad and happy moods compared to people born in winter. Those who always feel positive are mostly born in spring or summer.

The study also found that those born in fall less probably had a mood of depression which may easily drive them to cry, while those in winter were not easier to be angry.

Scientists said that this was probably because the seasons had an influence on certain chemicals in the human body. And the chemicals are important to control people’s moods even in adult life. “It seems that when you are born may increase or decrease your change of developing certain mood, disorders, ” scientist Xenia Gonda told the Telegraph.
