The Effect of Ageing on The Immune System, A Review

Abstract

The immune system's performance declines as we age, increasing our vulnerability to illnesses and perhaps lowering our quality of life. Stress and normal ageing both cause a decline in immune function. Social and psychological pressures are a regular component of life and the cause of significant events that alter direction. Throughout their lives, people are exposed to a variety of stressors, with effects that develop at various rates due to differences in stress exposure, stress buffering, stress reactivity, stress duration (recovery), and restorative mechanisms. The consequences of these processes on older persons' stress levels have been shown to mimic, aggravate, and possibly accelerate the immune system's ageing process. Therefore, it would be advantageous for aged people and less expensive for society to be able to renew the ageing immune system.
