SYDNEY, Nov. 28 (Xinhua) -- A new global study published Tuesday has found regions with an average temperature of 22 degrees celsius are the happiest and most social in the world.
Australia's University of Melbourne, along with Peking University in China, surveyed over 1.6 million people across the United States and China in order to test the relationship between ambient temperature and personality.
"Temperature is a crucial environmental factor that is associated with individuals' habitual behavioural patterns and, therefore, with fundamental dimensions of personality," the study said.
The research found that people living in areas where the temperature is closest to 22 degrees celsius, scored higher when it came to personality factors related to socialization and stability.
On average, those from cities around the 22degrees celsius mark are more likely to be extraverted and open to new experiences.
They are also statistically more emotionally stable, conscientious and agreeable.
"Clement (mild) temperatures encourage individuals to explore the outside environment, where both social interactions and new experiences abound," the research said.
