New Delhi: Japan has consistently excelled in the global longevity charts, with its citizens living longer and healthier than those in any other country. While a healthy lifestyle remains very essential for vitality and overall well-being, one important question remains—Does blood type play a role in slowing the aging process? A 2004 Japanese study involving 269 centenarians in Tokyo found that blood type B was more prevalent among those over 100 years old compared to a control group. This study suggests that there can be a link between blood group B and exceptional longevity. However, subsequent studies have presented conflicting results.
Is there any link between blood type and longevity?
Humans have four main blood groups—A, B, AB, and O—determined by the presence or absence of specific antigens in the red blood cells(RBC). Scientists have been researching how blood type might influence aging and disease susceptibility.
Dr. Sumit Agarwal, Director & Head of Internal Medicine at Sarvodaya Hospital, Faridabad, said, “It is difficult to tell that blood type significantly impacts longevity. While some studies suggest a connection, there isn’t enough research to confirm that a particular blood group can slow aging. Lifestyle and genetics play a more critical role in determining overall health and well-being.”
Does blood type influence health risks?
Individuals with blood group B often have a stronger immune response, better metabolic efficiency, and improved stress resistance, which may reduce age deterioration. Studies suggest that blood type B may contribute to slower aging due to its role in immune function, circulation, and stress adaptability. On the other hand, blood group O is also known to reduce the risk of blood clot formation, lowering the chances of heart disease and stroke, thereby minimising cardiovascular diseases. Conversely, blood groups A and AB have been associated with higher risks of autoimmune diseases.
Dr. Sumit Agarwal further said, “Some blood groups may be more susceptible to certain diseases, but this is not absolute. Lifestyle factors, such as diet, exercise, and mental well-being, impact more in preventing illnesses and promoting healthy aging.”
While global studies have explored the link between blood type and longevity, research in India remains limited.
Dr. Sumit explains, “In India, research on blood groups and disease prevention is not as advanced as in some Western countries because the primary focus is managing mental and physical health. India is fast becoming the diabetes capital of the world due to unhealthy lifestyle choices. Addressing these factors is more critical than relying on blood group-related research. While blood type may indicate certain genetic predispositions, medical advice is generally not influenced based on blood type. Instead, doctors focus on lifestyle modifications and managing pre-existing conditions to ensure well-being.”
Key Factors for a Healthy Life
Regardless of blood type, factors that contribute to a healthy life:
- Healthy Eating Patterns: Consuming a diet rich in fruits, vegetables, lean proteins, and whole grains and avoiding excessive sugar intake helps to prevent chronic diseases.
- Prioritising Physical Activity: Doing daily exercise, be it walking, yoga, or strength training, promotes cardiovascular health and reduces the risk of metabolic disorders.
- Mental Health: Prioritising mental well-being through mindfulness, meditation, and maintaining social connections can significantly impact overall health and longevity.
“Regardless of the blood type, a positive approach to health—through proper diet, regular exercise, and mental well-being—is the most effective way to promote longevity and prevent diseases,” Dr. Sumit concluded.
