Month of Birth Can Affect Health


Numerous studies have shown an association between temperament and health with a person’s birth month. In people who are overweight, it could be because he was born during the winter.

Horoscope or forecast based on the zodiac and the time of birth is contradicted by science. But in fact, affect the life time of a person’s birth.

Hundreds of studies published in various journals have shown that a person’s month of birth associated with characteristics such as temperament, longevity and susceptibility to certain diseases.

Scientists say that some of these findings may be false, but if you see the facts, some things have a suitability which could be coincidence.

Other effects can be very real and not caused by the alignment of the planets, but due to environmental influences during pregnancy and early life.

Here is the effect of season on the health and personality of someone who has been found in several scientific journals as reported by the LA Times:

1. Winter (December 22-March 20):

Weight loss:
The man who was born in this month tend to be obese. David Phillips of the University of Southampton in England analyzed the body weight of 1,750 British elderly people and found that 13.8% of men born in the month of January to March are obese.

Only 9.4% of those born in October through December. but in women, this trend becomes less clear.

Phillips argues that exposure to cold temperatures early in life may trigger the development of fat tissue and the influence of obesity in adulthood. Laboratory studies support this theory.

Rats exposed to cold temperatures before or shortly after birth store more energy in the form of fat, even when the temperature is no longer cold.

Temperament:
2004 study of 448 people found that people aged 20-45 years who were born during the winter (October-March) are more likely to have the property looking like new things, curious, do not like things that are tedious, and tend to choose a hobby of diving than Sudoku .

But when he was over 45 years, people born in winter are less interested in new things than those born in the summer. This indicates that they are faster settling.

“Season of birth affects the temperament, but we do not know exactly why. Maybe something to do with the levels of serotonin and dopamine, brain chemicals that are important in the formation of personality. Throughout the year, production of these hormones fluctuate in the mother’s body and can affect fetal development. Studies in animals shows the fluctuations caused by changes in day length, “says Lars-Göran Nilsson, psychologist at the University of Stockholm in Sweden.

Schizophrenia:
Percentage of mental illness in the general population is about 1%, but the people who were born in winter are more prone to experience it.

The observations, published in 1999 in the New England Journal of Medicine, found that people born in early March in the northern hemisphere has the possibility of 11% more likely to develop schizophrenia than those born in early June or early December.

But in the southern hemisphere the equator, the pattern is reversed. People born in August and September have the lowest risk for having schizophrenia.

2. Spring (March 22-June 21)

Height:
According to Gerhard Weber, an anthropologist at the University of Vienna, people born in the spring tend to be more height. He analyzed the measurements made on the Austrian Federal Army over half a million men.

Weber found that the recruitment of men is highest in people who were born in April, and the shortest was born in October.

Although the average difference is small enough (0.2 inches or 0.5 cm), whose findings were reported in 1998 in the journal Nature this was statistically significant.

Weber in his study speculated that this effect could be due to the concentration of the hormone melatonin in the body of the mother.This hormone dependent by light exposure and induced stimulation of growth hormone.

Multiple sclerosis:
Spring births have a higher risk of disease multiple sclerosis. The disease is caused by a combination of genetic and environmental factors. Research has established that the higher the latitude location of a country, the higher prevalence of multiple sclerosis.

Among the countries of Australia, the risk in subtropical Queensland five-fold greater than in the tropical Tasmania.

A 2005 study of 17 874 Canadian patients and 11 502 British patients found that those born in the month of May has 23% increased risk of multiple sclerosis compared with those born in November.

The cause is presumably because the concentration of vitamin D deficiency in the mother when the end of the second or third trimester of pregnancy

3. Summer (June 22-September 22)

Sleep Habits:
The study found that people who repeat the year in June to September would rather stay up compared to those born in winter.

A 5720 survey of European college students published in 2009 in the journal Sleep shows that people born in August to start sleep 19 minutes slower than average.

The researcher, Vincenzo Natale from the University of Bologna, Italy, argues that the body’s internal clock has been set at first people were born.

According to Natale, in summer, abundant sunshine and maturity affect the biological clock. But the tendency to sleep late at night is also strongly influenced by genes.

“If someone has a gene that tends to like to sleep late at night were born during the summer, he will be a night of extreme type. But if he was born in the winter, he will be in the middle,” said Natale.

Left:
People born in the summer and spring greater kemungkinnya become left-handed.

A study published in 1994 in the journal Perceptual and Motor Skills examine the trend of left-handedness among men conscripted French, American baseball player, and from data collected by the U.S. Census Bureau.

The result, 41.2% of all left-handed people born in March through July.

Maryanne Martin professor of psychology at the University of Oxford and Gregory Jones of the University of Warwick confirm these results in 1999. They still can not explain why these differences occur.

Factors that may affect the variation of maternal nutrition during pregnancy, exposure to sunlight, temperature, or seasonal infections during the second trimester of pregnancy.

Diabetes:
Children who are born in summer are more likely to develop type 1 diabetes. In this disease, the immune system kills the cells of the pancreas that produce insulin.

In a 1999 study of 1248 children with diabetes in Sweden, published the journal Archives of Disease in Childhood, children who were born in August are more likely to develop this disease.

4. Autumn (September 23-December 21)

Life span:
People born in the fall have a greater chance of living into old age. A study in 2011 that was published in the Journal of Aging Research analyzed the birth month of 1574 people who live to be 100 more then compare with his brother.

“Siblings of people who can live to 100 years of age who were born in the month of September to November have an opportunity of 30% – 50% higher can live to 100 years compared to those born in March,” said the researcher, Leonid Gavrilov of the Center on the Demography and Economics of Aging at the University of Chicago.

According to him, various factors can explain this, among others: maternal nutrition during the last months of pregnancy, seasonal infections, the temperature during birth or conception and levels of vitamin D.

Allergy:
Research conducted in Scandinavia, the Netherlands and Japan showed that the risk of higher food allergy found in children born in autumn or winter than those born in the summer.

Allergist, Dr. Milo Vassallo from Brooklyn, NY, 1000 saw more cases associated with acute food allergy reactions in a Boston hospital. He found that the birth of autumn and winter have the possibility of having food allergies 53% higher. According to him, it could be caused by seasonal fluctuations of vitamin D. Vitamin D deficiency can weaken the immune system.

“Because this is a good source of vitamins and supplements from the sun, then the risk of allergy depends on the place of residence. The latitudes higher and excessive fluctuations in exposure to sunlight causes a child born in the fall and winter in Boston has a higher risk of allergies compared with children in Los Angeles, “said Dr Vassallo.
