Medical Evidence of Schizophrenia

Prof. Dr. Ong Hean-Tatt 5th March 2009


We have discussed in a previous article that, in the Northern Hemisphere, the annual seasonal variations in the solar shadow form the Yin Yang, and also the 8 trigrams of the Early Heaven Bagua. The evolution of the Tai Chi into the Yin Yang and then 8 trigrams of the Early Heaven Bagua is actually a scientific flow chart of the transformation of the solar energy through the year. The so-called Wu Chi is nothing more than the Sun! This means that, for the Southern Hemisphere, the pattern of the Early Heaven Bagua needs to be changed for the Southern Hemisphere.

Surprisingly, there are scientific evidence of a medical nature that Feng Shui and astrology effects have to be reversed for the Southern Hemisphere. My book "Scientific and Statistical Proof of Chinese Astrology" discussed one such medical phenomenon is that of schizophrenia, as discussed again below.

Schizophrenia Associated with Months of Birth

Many independent researchers found that people who were born during certain times of the year (winter and early spring) have a higher than normal incidence of schizophrenia. The research suggests people who develop schizophrenia in Europe and North America are more likely to be born in the winter and early spring (February and March in the Northern Hemisphere).


Majority of practitioners are using the wrong directions for the Southern Hemisphere.

Subjects who were born during these months had a slightly higher than average rate of schizophrenia, while subjects born in August and September had a slightly lower than average rate. There is about a 10% difference in risk of schizophrenia between the high (Winter and Spring) and low risk months of birth.

Relative Risks of Schizophrenia according to Month of Birth


Using the sundial to measure the solar shadow to get the directions was the true ancient way of fixing the directions. The implications for the Southern Hemisphere have been missed out by most practitioners.

Statistical Analysis

The above Figure shows that the incidence of schizophrenia was highest among those born in March and lowest in those born in September. Statistical analysis of the birth data with the prevailing air temperatures and daylength shows that the incidence of schizophrenia was significantly associated with lower temperatures and shorter daylength, especially in the few months before birth. In fact, the coefficient of 0.916 means that, more than 84% of the variations in schizophrenia could be accounted for by daylength at 2 months before birth.

The statistical analysis supports the suggestion that the association between winter/spring births and schizophrenia may be related to sunlight exposure. The shorter days of winter will lead to a lack of sunlight, and in turn, can lead to vitamin D deficiency, which scientists believe could alter the development of a child's brain in the mother's womb and after birth.

  • A couple planning children may try to schedule the birth for a time outside the "winter and spring" time frame. As the research suggests that the birth months that have the highest risk of schizophrenia are February through April, conception should be avoided nine months before, during May to July.

  • It may not coincidence that the Chinese traditions identified the best months for marriage as in the 2nd Moon (around March) and 8th Moon (around September). The conception avoids the May to July period and this can reduce the risk of schizophrenia.

  • To further reduce risk of schizophrenia in the to be born child, a mother should get the recommended dose of vitamin D on a regular basis before and during pregnancy.

  • Chinese traditions recommend that during winter, people should eat food produced from seeds. These seed have very high levels of vitamins and can correct for the potential Vitamin D deficiency.

Some of the folklore therefore originated from wise observations of Nature. One laughs at the old mother's tales at one risk!

It has been suggested that the differences according to month of birth are due to prenatal influence. Some studies suggest that the susceptibility to circulatory heart diseases later in life may, among other things, also be determined by the nutrition of the mother during pregnancy. At the beginning of this century the food supply, like the availability of fresh fruits and vegetables in particular, differed from season to season. Mothers who gave birth in late autumn and early winter had access to fresh fruits and vegetables throughout most of the time of their pregnancy. But those who gave birth in spring and early summer may have experienced relatively longer periods of inadequate nutrition. "However, a study on the effect of the great famine in Finland in the years 1866-1868 showed that cohorts born shortly before or during the famine did not have a higher mortality risk later in life than those born after the famine."

Most do not really understand the Luopan. For example, some, like the Yang Gong people, do not understand Lai Bu Yi's Ren Pan and think he had created a useless Luopan ring. Well, these people are wrong as their knowledge is not deep enough for them to understand Lai Bu Yi's Ren Pan.

Reversal for Southern Hemisphere

The association of schizophrenia with the spring months in the Northern Hemisphere is reversed for the Southern Hemisphere:

  • A sample of 2514 adolescents and young adults presenting to general practitioners completed measures of depressive and suicidal symptoms. Patients' date and country of birth were recorded. Those born in the Southern hemisphere in September–November showed the highest suicidal and depressive symptoms, as did those born in the Northern hemisphere in March–May. Season of birth may be a risk factor for depressive and suicidal symptoms. (Joiner et al, 2002)

  • A review by Torrey et al. [19] consists of more than 250 studies covering 29 countries in the northern and 5 in the southern hemisphere. For the northern hemisphere most of these studies find a significant excess of births in winter and spring (December to May) for schizophrenia. A study on schizophrenia in Queensland, Australia, suggests for those born in the southern Hemisphere an excess birth in their winter (July to September), while those born in the northern Hemisphere had a March–April birth excess [13] . A recent study in Denmark on the effects of family history and place and season of birth on the risk of schizophrenia [16] found an excess of spring-births. The authors come to the conclusion that, although in most or all cases genetic factors are a necessary cause of schizophrenia, they are modulated by environmental factors such as the season of birth. (Doblhammer, Gabrielle. 1999 - 2000)

Reversals of association of diseases with months are also seen in other diseases like multiple sclerosis, suicides patterns and life span.

Astrological and Feng Shui Effects are Reversed for Southern Hemisphere!


Raptors are among the migratory birds which migrate from North Hemisphere to South Hemisphere and vice versa according to the different properties of the seasons. What nonsense to ignore the differences of the North and South Hemispheres.

Schizophrenia at Equator

What is interesting about these reversals in schizophrenia is that the reversal was not seen in a Singapore study, where there are no seasons due to the nearness to the equator:

  • 9,655 patients discharged from Singapore's national psychiatric hospital with a diagnosis of schizophrenia were included (year of birth range 1930-1984) (Gordon Parker et al. 2000.). The aggregated data was analysed, as well as the data of subsamples grouped according to birth-year periods, in order to examine secular trends. One patient subsample (those born 1960-84) allowed exact matching against the general population data set and close testing of any seasonal influence.

  • Monthly variation in births was evident for both patients and controls. The patterns were very similar, apart from the patient sample showing a trough in March-April. It was concluded that in an equatorial region, where there were no seasons, no seasonal excess in births of those later developing schizophrenia was evident.


It is quite clear that these associations of health parameters with the months of birth were influenced by seasonal factors impacting on foetal development during pregnancy. Thus, the seasonal reversal between the Northern and Southern Hemispheres causes similar reversals in the associations of health parameters with the months of birth.

This discussion confirms that Feng Shui and astrology effects would be reversed for the different hemispheres. It does also indicate that the Feng Shui and astrology effects may not be so pronounced at the equator.

Whatever it is, it is time to use scientific reasoning to unravel the true principles of Feng Shui and astrology. Most Feng Shui and astrology practitioners are rather unscientific and have much to catch up.
