There have been a few scientific research studies on the relation between blood type and traits of a human. Some of these researches, especially those coming from Japan have claimed that there’s closer relation between the blood type of a person and their temperament, chances of becoming sick or a few other characteristics.
In fact, the Japanese scientists have been studying this area since the 1930s. Although the relation is not precise, the researches have helped make some fascinating findings, some of which are described here.
O Type Blood
According to the Japanese Institute of Technology, which conducted many researches, people having O type blood are more likely to attract certain kinds of mosquitoes compared those having other type of blood. Such people have lesser resilience to stress, as cortisol (a hormone) lasts longer within their body and speeds up the process of aging. This group of people are open minded and outgoing.
A Type Blood
As per Neuropsychobiology (a leading magazine), those having type A blood are more likely to have obsessive compulsive disorders. One of their key traits includes highest level of persistence among people with all types of blood. They are also reserved and intelligent.
B Type Blood
The Japanese scientists claim that those with type B blood are fascinating. These are considered more contradictory kind of people than any other blood group. If you have B type blood, you are strong, highly passionate and creative. At the same time, you could be impulsive and selfish.
AB Type Blood
Neurology (another leading magazine) published that people with AB type blood group have increased chances of difficulties and issues in memorizing through the years. Tests involving older people found that those having AB type blood faced issues when it came to learning and memorizing information. But the good things with these people is that they are highly concerned about their environment. They have also shown good ability in adjusting to new changes without their personality getting affected.
