Stress, immune system and age

As ageing is associated with immunological changes, the effects of stress and age are interlinked where a deregulation of the immune function can have a significant impact on physical health. On the other hand stess can both enhance and increase the effects of aging, with older adults often showing greater immunological impairment to stress than younger adults. Therefore a good immune response is essential to our good health. In the same way immunological alterations and disturbances can influence the progression and severity of a variety of disorders and diseases, including stress related disorders.

Also stressful experiences very early in life can alter the responsiveness of the nervous system and immune system. It is possible that prenatal or early life stress may increase the likelihood of altered immune responses to stress in late life. One such alteration to the immune system includes a decrease in the ability of white blood cells (immune cells) to carry out their key functions. One great example is temporary stress as seen in students during examination stress. This has been seen to slow down wound healing. Children of mothers who are routinely stressed during...
