The birth season can predict so many things

Be born in different months, will it affect our personality and behavior?

This is not a question related to astrology.

But it does involve shining on the planet we grew up on: the sun. Even in the dark womb, the fetal brain may be affected by seasonal fluctuations ( changes in the length of sunlight ). Scientists have been attracted by this idea for decades.

Studies have found that babies born in autumn and winter ( October to March in the northern hemisphere ) are more interested in sensory stimulation than babies born in spring and summer. If a child is born in these months, her sensory seeking scale is likely to be relatively high. His desire for sensory stimulation was strongest when he was 26 to 30 years old.

They don’t mind going to a new place without preparation. They are eager to explore and experiment. When dating, they appreciate more ” sensory stimulation” and ” earthy” body odor. In aesthetics, compared with the clarity and harmony of classical art, they often prefer the color conflicts and uneven chaos of modern art. They are eager for impact.

At least when they were young, they were like this. Some studies show that compared with those in their 30s, women in their 40s born in autumn and winter will change this wavering mentality and have less pursuit of sensory stimulation than their peers. Compared with people born in other months, people born between October and March will have a great increase in their interest in seeking novelty in adolescence, but this interest will suddenly drop in middle age.

Emotion is closely related to the intensity of emotion and the desire to seek stimulation. Emotions are also regulated by dopamine. This neurotransmitter plays a certain role in extroversion or introversion, nobility or tact, workaholism or family care. Dopamine is concentrated in the ” emotional brain” or limbic system, enabling us to pursue happiness and rewards ( such as food, drinks, sex, praise, etc. ). Literally, this is something that pushes and shocks us.

When dopamine is exhausted, we can hardly move, just like patients with Parkinson’s disease.

By testing the blood of infants and young people, scientists found that those born in November to December had the highest level of dopamine metabolism, while those born in May to June had the lowest level of dopamine metabolism ( opposite in the southern hemisphere in these months ). This indicates that the increase in excitement may be related to a sharp increase in dopamine activity in people born in autumn and winter. Just as their interest in new things plummets in adulthood, so may their dopamine levels. Perhaps this helps to explain why people born in winter are more likely to suffer bipolar depression and schizophrenia and score lower on the consistency test.

What the hell happened? The main ideas will all involve the ” biological clock”. How effective the biological clock can be depends on how much sunlight the mother can shine during pregnancy or shortly after the baby is born. No one knows exactly how the biological clock of the fetus works and is set, which genes are silenced and which are activated. However, the mechanism of operation may involve melatonin, a hormone that can infiltrate through the placenta and affect the fetal brain. Melatonin levels depend on sunlight exposure. Melatonin levels are highest at night and during the darkest months of the year. Your melatonin level tells your fetus the time of day and the season of the year, and your fetus uses this information to set its own rhythm.

In dark months when melatonin levels are highest, dopamine levels are lowest. In sunny months, the days are longer and dopamine levels rise. For babies born in autumn and winter, the biological clock setting starts during the period when the daytime is getting longer during pregnancy.

During this period, pregnant women are exposed to more light and produce less melatonin. Does this signal increase the dopamine activity of the fetus? This is unknown, but once the biological clock is set, it will remain in operation for a long time after the baby is born.

Some researchers believe that the biological clock can explain why those born in autumn and winter ( in the northern hemisphere ) are more likely to get up earlier, to have bright eyes at dawn and to be energetic at dusk.

A popular theory holds that people born in autumn and winter are more likely than those born in spring and summer to adjust their life rhythm to receive sunshine for a long time in order to get more light to adapt to the weak light conditions in winter. Men born between April and September are more likely to suffer from seasonal affective disorder ( SAD ), and depression usually occurs in late autumn and winter.

People born in warm months are luckier than those born in other months if their mood is not affected by seasons. A survey of more than 22,000 adults shows that most adults over the age of 30 think they are the luckiest to be born in spring. Compared with those born in dark months, those born in spring ( especially those born in may ) are more optimistic, outgoing and sunny. They are more likely to expect good things to happen to themselves.

Interestingly, among those born in November, the number of people who think they are lucky is the least. The authors of the study believe that it may also be related to dopamine. Maybe people born in spring can avoid the sharp decline of dopamine activity as those born in autumn and winter when they approach middle age.

Anthropologist Dan Eisenberg believes that there may be evolutionary reasons for the influence of birth season on personality traits. Nearly 12,000 years ago, the earth experienced colder and darker periods for decades to hundreds of years, which is equivalent to a semi-permanent autumn or winter. Even people born in spring and summer will be pushed into a world with less sunlight.

At a time when there is less food available, wars are frequent, and life expectancy is low ( most people may not live beyond the age of 30 ), those behaviors seeking stimulation may be more conducive to survival. Under such circumstances, young people are more likely to stir up agitation, are more willing to try exciting travel, and rely on their own strength to explore the unknown world.

The relevant research results on the relationship between birth season and behavior are striking. However, psychiatrist Jayanti Chotai warned us after many studies that the difference caused by the birth season is very small and we cannot predict the future development of each baby based on it. These models are only statistically significant. Other factors in life obviously have more influence on personality.

Is it just a coincidence that young sensual pursuers may be Sagittarians? Sagittarius ( born November – December ) is a famous traveling explorer. At the same time, Taurus ( April – May ) has a stable personality. These personality traits roughly correspond to the previous research results: babies born in autumn are more adventurous, and babies born in spring have stable dopamine levels throughout their lives.

Astrologers may be right in some ways, but their explanations are wrong.

The predictions made by these astrologers are difficult to find evidence at a deeper level. A well-received study involved 2100 ” time twins,” people who were born one after another in London within five minutes on a certain day in March 1958. After testing hundreds of behavioral variables ( including intelligence, social skills and physical fitness ) of Pisces, the researchers concluded that they did not have much in common with any random group of Londoners. Other studies involving astrology try to match birth periods with individuals or require subjects to choose which of the three birth periods they are in. All these tests failed.

The birth period was written in the language of circus manager barnum, using a vague ” one size fits all” expression ( inappropriate expressions will be ignored ). As the great treacherous little man himself said: ” A good circus should have something that applies to everyone.” This is the case with astrology.
