Some say that the type of blood only matters at the time of a transfusion, but science has been looking further. Researchers have analyzed data from thousands of people over the last few decades and found curious evidence: there is a blood type that appears to be associated with greater longevity.
Can blood influence life expectancy?
According to a study conducted in Japan in 2004, quoted by several scientific publications, individuals with blood type B appear to have a life expectancy higher than average. Researchers observed that this group had a lower incidence of degenerative diseases at advanced ages.
According to the same source, the results aroused the interest of scientists in different countries, leading to new studies to deepen the possible relationship between blood type and aging.
Type B and resistance to cellular aging
Blood type B is defined by the presence of antigen B on the surface of the red blood cells. As the investigation continued, hypotheses began to emerge on the impact of this antigen on cell metabolism and health. Writes the scientific portal Healthline That one of the possible explanations may be related to the immune response and greater resistance to oxidative stress, one of the processes responsible for premature cell aging.
In addition, according to the same source, type B blood may have better responses to inflammatory processes, which helps explain the lowest rate of chronic inflammatory diseases between this group.
Rare but interesting
Although it is less common than types A or O, group B is more prevalent in certain regions of Central Asia. Refers to the Site Medical News Today that this data has driven investigations in populations with high concentration of this blood type.
The scientific interest in this group has increased, not only for the possible connection with longevity, but also by the differentiated immune response observed in other contexts, such as virus resistance or infections.
Other factors that also count
Despite this data, experts stress that the blood type is just one of the puzzle pieces. Lifestyle, diet and exercise are still decisive.
Refers to the Site EatingWell That maintaining a balanced diet, avoiding tobacco and managing stress well are elements that directly impact cardiovascular health, the immune system and longevity. According to the same source, genetic predisposition can be moderate by conscious choices, and the environment where you live (with access to health care, pollution or climate) also influences.
Life expectancy is multifactorial
It is not, therefore, a destination written in the blood. Longevity results from the interaction between genetics, environment and behavior. Even within the same blood type, there are significant variations between people with different habits.
Adds the publication That, despite the relationship identified in large -scale studies, it is not possible to say that the blood type determines, by itself, a longer life.

A field still under investigation
The relationship between blood types and health has been studied in multiple contexts, from susceptibility to cardiovascular disease to the risk of certain types of cancer. According to the same source, there are also studies that try to understand if certain blood types influence the response to vaccines, medications or even specific diets.
What if your type is not B?
There is no reason for alarm. Even if its blood type is not associated with these discoveries, evidence points to the predominant role of healthy habits in promoting longevity. According to the same source, regular exercise, quality sleep and positive social contact remain the most solid pillars to grow old.
Blood Types Curiosities
The four main blood groups are A, B, AB and O, and each can be positive or negative HR. This combination influences compatibilities in transfusions, but has also been studied in relation to disease and genetic profiles. For example, people with type O Type O have a lower risk of heart disease, according to some studies, while type AB may be more associated with age deficits with age.
Scientific research continues to collect data and test hypotheses, and new studies are likely to reveal more links between genetics, blood and longevity. Until then, known conclusions should be interpreted with caution and always in the context of a healthy and balanced lifestyle.
