Study shows that season of birth affects personality – sounds like astrology

A new study to be presented at the European College of Neuropsychopharmacology (ECNP) suggests that there may be something in astrology after all. The study is being presented at the ECNP Congress in Berlin. The researchers from Hungary find statistically significant links between season of birth and mood disorders.


I have always thought of astrology being ridiculously fanciful and horoscopes just so much hokum. But a tiny little part of my brain is always a touch uncertain. Clearly the seasons are controlled by the Earth’s relative position and its motion around the Sun. If the season of birth can affect personality then the effects of the Sun and other celestial bodies become real. That the moon may have effects on the results of cardiac surgery is apparently not just rubbish. The lunar nodal cycle does seem to correlate with happenings on Earth. The mechanisms leading to most lunar effects on tides and sedimentation and geologic accumulations and tidal flows and sea surface temperatures and climate can be put down to some interplay of gravitational forces. It is not such a long stretch to think that the gravitational effects of the larger planets may have some quite unlooked for effects on life on Earth.

Back in the days of psychedelia and Hair, we used to think that strange things would take place as the age of Aquarius dawned,  “When the moon is in the seventh house, And Jupiter aligns with Mars”.

Neuropsychopharmacology however is something quite new for me and sounds almost as arcane as astrology.

 Neuropsychopharmacology, is an interdisciplinary science related to psychopharmacology (how drugs affect the mind) and fundamental neuroscience, and is the study of the neural mechanisms that drugs act upon to influence behavior.

Professor Xenia Gonda is a clinical psychologist and pharmacist currently working as assistant professor at the Department of Clinical and Theoretical Mental Health at Semmelweis University, Budapest.

AlphaGalileo: According to lead researcher, Assistant Professor Xenia Gonda 

“Biochemical studies have shown that the season in which you are born has an influence on certain monoamine neurotransmitters, such as dopamine and serotonin, which is detectable even in adult life. This led us to believe that birth season may have a longer-lasting effect. Our work looked at over 400 subjects and matched their birth season to personality types in later life. Basically, it seems that when you are born may increase or decrease your chance of developing certain mood disorders”.

“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 season of birth and mood disorder”.

The group found the following statistically significant trends:

  • cyclothymic temperament (characterized by rapid, frequent swings between sad and cheerful moods), is significantly higher in those born in the summer, in comparison with those born in the winter.
  • Hyperthymic temperament – a tendency to be excessively positive –  were significantly higher in those born in spring and summer
  • Those born in the winter were significantly less prone to irritable temperament than those born at other times of the year.
  • Those born in autumn show a significantly lower tendency to depressive temperament than those born in winter.

 Commenting for the European College of Neuropsychopharmacology, Professor Eduard Vieta (Barcelona) XY said:

“Seasons affect our mood and behavior. Even the season at our birth may influence our subsequent risk for developing certain medical conditions, including some mental disorders. What’s new from this group of researchers is the influence of season at birth and temperament. Temperaments are not disorders but biologically-driven behavioral and emotional trends. Although both genetic and environmental factors are involved in one’s temperament, now we know that the season at birth plays a role too. And the finding of “high mood” tendency (hyperthymic temperament) for those born in summer is quite intriguing.”
