[The Epoch Times, June 15, 2022](Reported by The Epoch Times reporter Chen Juncun) People encounter all kinds ofpressure, these pressures will not only affect the psychological level, but also have an impact on physical health.A recent study in the United States found that stress acceleratesimmune systemofAgeingincreasing the risk of disease.
According to the University of Southern California website, as people’sAgeinghumanimmune systemIt also declines naturally, a phenomenon known as immunosenescence.
Aging of the immune system has been linked not only to cancer, but also to cardiovascular disease and pneumonia, reducing the efficacy of vaccines and causing aging of organs.
but the sameageThe functioning of the immune system varies from person to person, apparently due to factors other than natural aging.
to understand the lifepressureUSC researchers analyzed data from the University of Michigan’s Health and Retirement Study to see if there is a relationship between aging and the immune system.
The Health and Retirement Study is a national study of the economy, health, marital and family status of older Americans.
USC researchers examined responses to a questionnaire from 5,744 adults over the age of 50 to measure their exposure to different forms of social stress, including stressful events in their lives, chronic diseases and discrimination.
The researchers also analyzed blood samples from the participants using a laboratory technique called flow cytometry to count and classify their blood cells.
As the researchers expected, those who were more stressed had older immune systems that seemed to have worn outleukocyteThe ratio is relatively high.
The researchers found that stressful events in life were still significantly associated with a reduction in naive T cells in the body when factors such as education, smoking, alcohol consumption, body mass index (BMI) and ethnicity were controlled for. strong connection. T cells are a type of lymphocytes that play an important role in the immune response.
Researcher Eric Klopack said people who were more stressed tended to have poorer diet and exercise habits, which is part of the reason their immune systems age faster.
Therefore, improved diet and exercise habits in older adults may offset the aging immune system that accompanies stress.
