Studies Indicate That Individuals With This Blood Type Have a Higher Likelihood of Living to 100 — What Does the Research Really Say?
You may have seen claims that a particular blood type is linked to living longer, but the relationship between blood type and longevity is complex. While some studies have found associations between blood groups and certain health outcomes, no blood type guarantees a longer life or determines whether someone will reach 100.
Which Blood Type Is Sometimes Linked With Longevity?
Some research has suggested that people with blood type O may have certain health advantages, particularly related to cardiovascular risk. For example:
- People with type O blood may have a lower risk of some types of blood clots compared with non-O blood groups.
- Certain studies have observed differences in rates of heart disease, stroke, and other conditions among blood groups.
However, these differences are generally small, and they do not outweigh major factors that influence lifespan, such as:
- Genetics
- Diet
- Physical activity
- Smoking habits
- Blood pressure control
- Access to healthcare
- Social connections
- Stress management
Why Might Blood Type Matter?
Blood type is determined by variations in genes that affect molecules on the surface of red blood cells. These differences may influence:
- Blood clotting factors
- Inflammation
- Susceptibility to some diseases
For example, non-O blood types (A, B, and AB) tend to have higher average levels of certain clotting proteins, which may slightly increase clotting risk in some situations.
What Do Many Centenarians Have in Common?
People who live to 100 often share lifestyle and health patterns such as:
- Eating a nutrient-rich diet
- Remaining physically active
- Maintaining healthy relationships
- Avoiding smoking
- Managing chronic conditions
- Staying mentally engaged
- Having a sense of purpose
