Do you easily become stressed out and anxious? If so, you’re probably thinking that you’re just a bit more fearful and burdened by life’s stresses than other people; however, your blood type could actually be the culprit of your anxiety.
The hormone cortisol, which plays a huge role in your stress and anxiety levels, is determined by your blood type. People who have type A blood naturally have higher levels of cortisol in their bodies, and they also produce cortisol in response to stressful situations as a result.

On the other hand, people with type O blood are prone to the “fight or flight” reaction to stress, which means more adrenaline floods their system than necessary, leading to panic and anxiety.
Understanding how your blood type affects your production of cortisol plays a key role in helping you manage your stress.
For instance, if you are Type O, you may need to understand that it will probably take you longer to recover from stress because it is more difficult for you to ease the adrenaline that your body produces. In order to help you alleviate your stress levels, try meditating first thing in the morning for an hour or more.
You can also pinpoint something that will calm you down and spend more time doing it, like reading a book or taking a walk. Dealing with too much stress on a regular basis can be just as negative on your health as any disease, so form a battle plan to help you combat the stress levels.
That’s just one of the ways that your blood type can impact your health. Another way is that it can play a big part on the bacteria in your gut.
New studies have found that your blood type can actually play a big part on the way your intestines break down the bacteria in your gut. This is a pretty big deal because if a doctor can identify what types of bacteria you are storing in your gut based on your blood type, your diet can be adjusted accordingly.
Your blood type can also play a major part in your risk for developing alcoholism. Studies have found that people who are type A have a higher risk of developing this disorder. That’s because specific components in the blood – antigens – are linked to the disease, and type A antigens can actually transform the way your immune system reacts with alcohol.
Blood type can also gauge how anal you are. People with type A blood are more likely to be obsessive-compulsive. In other words, if you have type A blood, you’re probably a lot more persistent than someone with type O blood.
Your blood type can attract mosquitoes, too. People with type O blood are two times more likely to attract specific types of mosquitoes than people with other blood types. However, on the positive side, while you may get more bites, you’re less likely to suffer from illnesses that are related to mosquitoes, including malaria.
