19.Babies born in summer are much more likely to suffer from mood swings when they grow up while those born in winter are less likely to become irritable adults,scientists claim.
Researchers studied 400 people and matched their personality type to when in the year they were born.They claim that people born at certain times of the year have a far greater chance of developing certain types of temper,which can lead to mood disorders.
The scientists,from Budapest,said this was because the seasons had an influence on certain monoamine neurotransmitters (单胺类神经递质),which control mood;however,more research was needed to find out why.
They discovered that the number of people with a"cyclothymic"temper,characterized by rapid,frequent swings between sad and cheerful moods,was significantly higher in those born in summer.The number of those with a hyperthymic temper,a tendency to be excessively positive,was significantly higher among those born in spring and summer.
Lead researcher,assistant professor Xenia Gonda,said,"Biochemical studies have shown that the season in which you are born has an influence on certain monoamine neurotransmitters,which are detectable even in adult life."
Gonda added,"We can't yet say anything about the mechanisms involved.What we are now looking at is to see if there are genetic markers which are related to the season of birth and mood disorders."
The study may well provide a clue as to why some of the nation's best-known personalities are good-natured,while others are slightly grumpier.The Duchess of Cambridge was born in winter,on January 9,which according to the study,means she is less likely to be irritable while Roy Keane,the famously hot-headed former Manchester United footballer,was born in August,when the scientists say people are more likely to have mood swings.
Professor Eduard Vieta,from the ECNP,said,"Although both genetic and environmental factors are involved in one's temper,now we know that the season of birth plays a role too.And the finding of‘high mood'tendency for those born in summer is quite interesting."
