With age, the immune systems naturally start to decline. This aging of the immune system, known as immunosenescence, may be a crucial part of age-related health difficulties such as cancer and cardiovascular disease, as well as older people’s less helpful response to vaccines.

However, not all immune systems degrade at the same rate. In a recently published study, researchers found that social stress is related to signs of quickened immune system aging.

HRS researchers have started collecting blood from a variety of participants, counting the number of varied types of immune cells present, comprising white blood cells. These cells are central in immune reactions to viruses, bacteria, and other invaders. This is the first comprehensive information about immune cells that have been obtained in an extensive national survey.
By evaluating the data from 5,744 HRS partakers who provided blood and also answered survey queries about stress, the research team has found that people who suffered more strain had a lower percentage of “naive” T cells, which are the fresh cells needed to take on new invaders that the immune system hasn’t confronted before

They also possess a more significant proportion of “late differentiated” T cells, which are older cells that have depleted their ability to fight invaders and produce proteins that can boost harmful inflammation. People with low amounts of newer T cells and high parts of older T cells have a more aged immune system.

However, after controlling the poor diet and low exercise, the connection between stress and stimulated immune aging wasn’t as powerful. This implies that enhancing these health behaviors might assist in neutralizing the hazards related to stress.
