Scientists: People with This Blood Type Age More Slowly
People around the world want to extend their years of healthy living, but many are still unaware that their blood type may play a role in how quickly they age.
Results from a new study suggest that individuals with blood type B may age more slowly, raising many questions about what sets this group apart from others.
Tony Wyss-Coray from Stanford University has been studying these biological mysteries for years, with a special focus on the role of blood factors in maintaining vitality. His research emphasizes how blood can reveal important information about the “wear and tear” our bodies undergo as we age, reports Nova.rs.
Understanding Blood Type B
Blood types are determined by specific markers on red blood cells and antibodies circulating in the bloodstream. In the ABO blood type system, individuals with type B have B antigens on their red blood cells and produce antibodies against A antigens.
Only about 10 percent of the global population falls into this category. Scientists have investigated whether this unique marker may contribute to a more efficient response to metabolic changes, potentially helping these individuals age more slowly, according to the report by the National Library of Medicine.
Longevity Factors
Several decades ago, scientists began exploring the connection between blood types and lifespan.
"Our findings suggest that blood type B may be associated with exceptional longevity," concluded Shimizu and colleagues in Tokyo as early as 2004. Experts further analyzed why this group might outperform others in terms of longevity.
Some point to more efficient cellular repair mechanisms, while others believe their bodies cope better with metabolic stress, potentially protecting them from certain aging-related health issues.
Possible Downsides
Scientists note that people with blood type B are not immune to health risks. Research has shown a slightly increased likelihood of cardiovascular issues in these individuals. Good dietary habits, regular physical activity, and stress management can reduce this vulnerability. Additionally, this group is reputed to be more emotionally sensitive, and some believe they need a strong support network to maintain mental well-being.
Insight into Organ Aging
There is growing evidence that aging does not affect all parts of the body equally. Some organs may deteriorate faster than others, increasing disease risk even in people who appear outwardly healthy. One large-scale study analyzed over 5,000 volunteers to determine the biological age of 11 organs based on more than 4,000 proteins in their blood.
The study found that about 20% of the population experiences accelerated aging in at least one organ.
Blood as an Assessment Tool
Current methods often rely on epigenetic changes in DNA to assess aging, but these require tissue samples that are hard to obtain from every organ. Blood, however, is easily accessible and can provide instant insight into protein levels associated with various internal systems.
AI-based tools analyze thousands of these proteins and link specific levels to individual organs, revealing which body parts are aging faster than they should.
This data could be used in the future to develop personalized strategies for slowing down organ decline.
Practical Implications
The idea of detecting organ aging before serious symptoms appear is attractive but also raises important dilemmas. Knowing you're at risk for kidney or heart disease might prompt extra care, but it could also cause anxiety if there's no concrete treatment.
Experts advise combining such knowledge with preventive steps. For people with blood type B, special attention to heart health and stress management is recommended, as emotional well-being may be more vulnerable.
More Than Just Statistics
While statistics can be intriguing, daily habits usually determine how these findings impact life. A balanced diet, physical activity, sufficient sleep, and strong interpersonal relationships contribute to stable physical and emotional health.
Scientists encourage everyone curious about their own aging process to consider all possible factors. Blood type B may explain certain traits, but it is not the only factor in the equation. Advanced blood-based tests are not yet widely available. If they become common, people might be able to detect signs of organ aging earlier and respond in time.
Tony Wyss-Coray’s work shows that a simple blood draw can reveal hidden changes in different parts of the body — potentially opening the door to more targeted care, especially for those who want to maintain a high quality of life as they age, according to a study published in Experimental Gerontology.
