Researchers 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.
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.
We don’t know the exact mechanism for any of these phenomena, but researchers have suggested maternal infections, food availability during pregnancy, and sunlight exposure as possible reasons.

Influence on medical conditions
The season in which babies are born can have a dramatic effect on their future risk relating to the development of conditions such as neurological disorders, including seasonal affective disorder, bipolar depression, schizophrenia[2] and type I diabetes.[5] Research has shown that the season a baby is born in can have a major effect on whether or not you will become a heavy smoker. This even varies between men to women.[6]
As a factor in infant grown
The season during which a birth takes place has been linked to the weight development of the infant as well as initial weight.[7]
As a factor in academic development
There is evidence that suggests that children who are born earlier while they attend the same academic year with others, gain an advantage:
"In Britain the academic year begins in September, and there may be almost a year's chronological age difference between the eldest (September birthday) and youngest (August birthday) children in the same class. There is evidence that, in this context, children born in the autumn term (September to December birthdays) perform better academically, relative to their class peers, than those born in the spring term (January to April birthdays), who in turn outperform those born in the summer term (May to August birthdays)." [8]
As a suicide risk factor
Birth rates of people who later kill themselves show disproportionate excess for April, May and June compared with the other months. Overall, the risk of suicide increases by 17% for people born in the spring–early summer compared with those born in the autumn–early winter; this risk increase was larger for women (29.6%) than for men (13.7%).[9]
Research works in Sweden show that those who preferred hanging rather than poisoning or petrol gases were significantly more likely to be born during February–April. Maximum of the month-of-birth curve for preferring hanging was for March–April and the minimum was for September–October.[10]

- тогда все кто во Флориде родились должны быть с одним характером, а кто на Аляске - с другим...

Today is a first day of the rest of your life
не надо понимать текст с такими крайностями
посмотри, там все на вероятностях, не более
и разумеется ты права, люди родившиеся на юге в целом несколько отличаются по характеру от родившихся на севере
это уже тысячу лет как известно
даже наличие некоторых ключевых микроэлементов в почве той или иной ,местности оказывает влияние на развитие плода
