Recently, the Guangdong provincial population and family planning officer, maple in a thematic report noted, 10, 11, 12 3 months baby, born than the other seasons.

Zhang believes that autumn is the season of the "windfall", in the autumn and early winter of childbirth, consistent with the nature of climate rhythm.

However, a "windfall" used in the human body is not appropriate.

In General, the natural conditions of temperate fauna is not suitable for reproduction in the autumn. In fact, the old saying goes: election day than the day hit.

In accordance with the General rules of mammalian nature, autumn is the best time to descendants.

Birth statistics

Germany Munich University of Ron Schneeberg (Roenneberg) and the Max Planck Institute of joash Hough (JürgenAschoff) in 1990 published famous thesis human reproductive cycle of the year — biological, sociological or both "in the time span of up to 3000 years of human birth month data made a detailed study, they pointed out that the peak of the birth of mankind, took place in the spring equinox day each year, is also nearby, in late March.

It is conceived for 40 weeks on, birth peaks appear in January of each year – in February.

Fujian medical epidemiology studies of Xu to Jeffrey and Wu Rong under the Chinese population statistics yearbook 1990 "in 1944-1989, China's population born statistical analysis showed that the Chinese population birth peaks in mid-November.

The fourth military medical University of Yu ya in statistics "17000 than thinkers, politicians, scientists, literary artists, social activists, as well as the personalities of birth month," think "was born in the winter month (that is, 10, 11, 12, 1, 2, 3-month) than was born in the summer months (4, 5, 6,

7, 8, 9) the number of people."

United States the biggest birthday card manufacturer Hallmark company statistics are displayed for the month of August in the United States men's birthday, 9.07%; and at least February, 7.55%.

Is no basis

The most obvious impact on fertility and month-related factor is the temperature, the temperature will reduce sperm survival.

Human testis "temperature" in the 34 ° c, slightly lower than the temperature. In 1967, Robinson and Roque (RobinsonD & RockJ) study found, through continuous wear can increase the testicular temperature of one degree centigrade of tight underwear for seven weeks, the decline in the number of sperm of 25%. Hence temperate universal hot summer also led to a decline in human pregnancy rates, taking into account the main world population lived in summer for June, July, August in the Northern temperate zone, so all of the statistics above, corresponds to the three-month 4, 5, 6, is born.

Another factor is the lighting.

Lighting time changes affect human melatonin secretion, melatonin is an ability to adjust the gonad function of substances.

Research has shown that when day length near the night length and continue to grow longer, before and after the vernal equinox, human activities are the most exuberant sexual glands. It is not difficult to explain why the "Spring" and reproduction activities related to always.

Social factors on the birth of even greater than the above these natural factors.

In China, for example, since our Spring 1 of each year, in February, this session is the peak of marriage is the "reunion", corresponding to 10 months later in November, December, nature has become a baby boom.

Associated with seasonal epidemic affects fetal development, scientists speculate, 1, 2, March-born people have a higher incidence of nervous system diseases are likely and the

ir mothers during pregnancy and late infection influenza related, because that happens to correspond to high incidence of influenza in winter. In addition, different seasons, people's diet is also no doubt influenced the development of the fetus.

Selected days as hit days

Just when the topic appropriate for pregnant, I consulted several colleagues mother.

Spring baby complain just when pregnant, hot weather in summer and pregnancy, restaurant not thinking; summer children's complaints are punished in the summer of confinement; autumn baby complaints bodies, the heat in summer and can't sleep, child full moon on the winter, cold all day; winter is complaining about the birth of confinement three months do not dare to take a bath. In short, the birth itself is a very hard thing.

The old saying goes, selected days gestation days than hit really is "ripe" and "windfall".

If you are saying according to Zhang, Director of the season "plan," birth, born in may, July, Marx was born of Caesar, Liu Xiang, born in September, this is actually the "plan". Pity it.

Birthday and disease — not a fortune teller

Scientists find birth month with certain diseases exist between some delicate touch.

In this context, they present a certain consensus. United Kingdom in Dyment, Willer, Poland bEmbenek, United States of Kolevzon, Knobler, Silverman and others, in recent years is considered to be part of the study focused on diseases among the population statistics, the following table summarizes their findings, showing the months born in common situations. Of course, you don't have to condemnation, because even if the evidence most definitely a schizophrenic, 1, 2, 3, born in the month than other persons born in higher incidence of only 6% to 8%. Please note that this is just the statistical significance of the conclusions.
