People With Type A And O Blood Have A Harder Time Dealing With Stress
Because your blood type antigens help determine how much cortisol your body releases, your blood type actually impacts how you feel when you’re stressed. People with type A blood produce more cortisol than other blood types, which makes it harder for them to handle stressful situations. People with type O blood don’t produce excess cortisol, but they do pump out excess adrenaline under stress, which makes it harder for them to clear up any cortisol in their systems.
People with these blood types may need to pay special attention to how they manage their stress because their bodies are less likely to do it for them.
People With Type B Blood Are Swarming With Good Bacteria
If you have type B blood, you’re in luck; you’re full of bacteria – the good kind. The human body needs bacteria to help it perform a variety of functions, including digesting food and fighting off dangerous strains of bacteria.
People with type B blood have up to 50,000 times the amount of friendly bacteria that people with O and A blood have, which means better digestion and a more powerful immune system.
Mosquitos Like Some Blood Better Than Others
Have you ever noticed that some people seem to get way more mosquito bites than others? It’s not just because mosquitos are unfair jerks – it’s because of your blood type. According to a Japanese study published in the Journal of Medical Entomology, people with type O blood are twice as attractive to mosquitos than people with type A blood. Type B and type AB are less attractive as well.
Mosquitos can tell a person’s blood type before sucking any blood, through information passed on via skin secretions. If they don’t like your blood type, they might just fly away.
People With Type O Blood Might Have A Harder Time Getting Pregnant
Researchers at Yale University and New York’s Albert Einstein College of Medicine found that women with type O blood are twice as likely to produce poor quality eggs in lower amounts. They’re also more likely to have high levels of the reproductive hormone FSH, which indicates low fertility.
Women with type A blood, on the other hand, are better protected against their egg count decreasing with age. That said, blood type isn’t the only factor that contributes to fertility, and age is considered a more meaningful indicator of reproductive success.
People With Type O Blood Are Less Likely To Develop Heart Disease
Having type O blood can seem like a pretty raw deal, but fear not, there are some major advantages, one of them being that people with type O blood are 23% less likely to develop heart disease than people with other blood types. People with types AB and B blood are at the highest risk.
This may be because some blood groups are linked with higher rates of inflammation, which can contribute to the development of heart disease.
