Astrology-related? Nope. In fact, it’s not even a new concept. But looking back through research history, findings are muddled and confusing.
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.
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.
The study is being presented at the annual conference of the European College of Neuropsychopharmacology (ECNP) in Berlin, Germany, on Sunday.
I recalled such statements from years ago. So, off to trusty Google search:
Research into environmental factors and brain development has been going on for a long time. This paper by Richard Wiseman from 2005 summarizes the research into neuropsychology. It’s complicated but there may be something to it as a small trend based on various environmental factors AND where you live, obviously.
As an example of the complication, take a look at these results…
Spring and early summer means a 3% higher risk for conceiving a child with birth defects in the U.S. possibly due to pesticide load but this has not been solidly confirmed.
A mice study showed that animals born in winter showed dramatic disruptions in their biological clocks possibly leading to the higher risk associated with Winter birth and mental health disorders.
Spring babies are more likely to suffer from anorexia nervosa as adults but also schizophrenia, multiple sclerosis and even Type 1 diabetes. Babies born in the fall have a higher risk of having food allergies,
The season of birth may affect everything from eyesight and eating habits to birth defects and personality later in life. Past research has also hinted the season one is born in might affect mental health, with scientists suggesting a number of reasons for this apparent effect.
The rate of contracting flu or lacking Vitamin D were mentioned as possible reasons. Once again, mental disorders like schizophrenia and bipolar disorder had statistically significant peaks in January, and lows in the summer.
In other words, there is a gigantic array of reasons why your birth month MAY leave you more susceptible to certain conditions but the statistical effects are small. It’s got nothing to do with astrology and it’s not worth worrying about. So do not read this thinking, “Oh, I was born in Winter so I’ll have psychological disorders”. That’s not how it works.
