A large study by scientists at the University of California, Los Angeles, USA, sought to better understand why people of the same age may have different immune ages. American experts have found that social stress is linked to the accelerated aging of the immune system and that is why it is recommended that people improve their lifestyle.
As people get older, their immune system naturally begins to decline. This process related to the immune system, immunosecretion, may be an important part of such age-related health problems as cancer and cardiovascular disease, as well as the less effective response to vaccines, according to Science Alert.
The study, led by Dr. Eric Klopack of the University of Southern California, looked at 5,744 participants over the age of 50 in the United States. Researchers at the Health and Retirement Study looked at the different types of stressors that people have experienced.
They also included stressful life events, such as job loss, discrimination, major trauma over the years, such as an illness that endangers a family member, chronic stress, such as financial stress. .
Analyzing the data of the participants, who provided blood and answered the questions related to stress, the team of experts found that people who faced more stress had a small proportion of “naive” T cells needed to cope. new invaders of the human body, of the immune system, whom he has never met before.

It has been found that people with lower proportions of newer T cells and high levels of older T cells have an older immune system.
The study helps clarify the association between social stress and faster immune aging. It also highlights potential ways to slow the aging of immunity, such as changing the way people cope with stress and improving life behaviors, such as dietsmoking and exercise.
Let us mention the fact that stress is a psychosocial phenomenon that arises from the person’s confrontation with requirements, tasks, situations, which are perceived as difficult, painful or of great importance for the person in question.
