Ever wonder why someone, somewhere decided to figure out if all human blood is the same? Thank goodness they did tough, because otherwise we’d never have known that there are basically four main blood group types. We wouldn’t have known about blood group compatibility and that our health and habits sort of depend on our blood group type.
Susceptibility to Diseases
People with O blood type have low risk of heart diseases but have high chances of developing stomach ulcers. Blood type A means higher risks of microbial infections whereas those belonging to AB and B have higher chances of developing pancreatic cancer.
Response to Stress
Blood type A has more cortisol in it, thus people belonging to this group tend to be more responsive to stress. O blood type people get flooded with adrenaline, which makes them resort to the “flight or fight” technique in dealing with stress.
Compulsive Disorders
Research had found link between blood type A and tendencies to have obsessive compulsive disorders.
Alcoholism
Recent studies have shown that the type A antigens may alter the reaction of the immune system to alcohol, which affects the effect of intoxication.
Attracting Mosquitoes
It has been found that people who belong to O blood type are more likely to attract mosquitoes. But lucky for them, they are found to be less susceptible to malaria than others, which is spread by mosquitoes.
