Why do the children of Samurai suffer from disabilities?

A new study reveals that it is the makeup of women who causes Japanese samurai warriors to be disabled and weaker than other children of the same age.

The famous Japanese samurai warriors are courageous, not afraid of anyone and always living with the mind will die like heroes in battle. However, they end up being cut down by an unexpected enemy: makeup.

Women's makeup powder is considered a source of infection
Lead poisoning is the children of Japanese samurai warriors.

Researchers found that children of samurai class had serious lead poisoning because of their cosmetic makeup. They grow up with disabilities, physical deformities and weak cognitive abilities.

It is these weaknesses that make the children of the samurai class unable to cope with political crises, leading to instability and ultimately the collapse of their feudal system, according to research. new research of Tamiji Nakashima from Japan University of Environmental and Occupational Health.

Mr. Nakashima studied the bones of children and adults of samurai class to discover their cause of death.

Based on chemical and X-ray analyzes, Mr. Nakashima and colleagues found that the bones of children in the study contained tens of times the lead levels detected in both adult male and female bones. . In particular, this index for children 3 years and under is 50 times higher than in their mothers.

White chalk for women is believed to be the cause of lead poisoning. German newspaper Der Spiegel quoted the research team as saying: 'During the Edo period (the reign of Edo or the Tokugawa shogunate in Japan, which lasted from 1603 - 1868), the use of make-up cosmetics became popular and fashionable. Representatives for this movement are often artists, geisha and luxury prostitutes as well as beauty experts'.

White powder powder applied to the face used at that time was made from mercury chloride and white lead. Lead levels in adult women 's bones are nearly double that of adult men in the study.

'And their milk is more likely to be highly toxic, leading to extremely high lead levels in the youngest children. High levels of lead in samurai-class children during the Edo period can cause them to suffer brain damage, intellectual weakness, and therefore are unable to cope with the final political crisis that takes place within from 1853 to 1867 and eventually led to the fall of the bakufu regime , 'said the team.

According to the World Health Organization (WHO), lead will cause many forms of disease and is especially harmful to children. Too much lead will damage the nervous system and reproductive system, causing high blood pressure and anemia and accumulation in the bones.

Lead is particularly harmful to developing brains of fetuses and young children. This chemical will interfere with the metabolism of calcium and Vitamin D, while causing irreversible effects, including learning disabilities, behavioral problems and mental retardation.

High levels of lead poisoning will lead to seizures, coma and eventually death.

'We think that lipstick is one of the main sources of lead poisoning in the samurai class because this face makeup is a luxury at the time. Inferior civilians (farmers and fishermen) are not eligible to use luxury products such as lipstick and the law also strictly prohibits cosmetic labor , 'Dr Nakashima told LiveScience.
