Scientists’ research shows people born in the summer are more likely to suffer from mood swings
Babies born in the summer are much more likely to suffer from mood swings when they grow up while those born in the 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 temperaments, which can lead to mood disorders.
The scientists, from Budapest, said this was because the seasons had an influence on certain monoamine neurotransmitters, such as dopamine and serotonin, which control mood, however more research was needed to find out why.
They discovered that the number of people with a “cyclothymic” temperament, characterised by rapid, frequent swings between sad and cheerful moods, was significantly higher in those born in the summer.
Those with a hyperthymic temperament, a tendency to be excessively positive, was significantly higher among those born in the spring and summer.
The study also found that those born in the autumn were less likely to be depressive, while those born in winter were less likely to be irritable.
