Question

Quizplus · Accepted Answer

A) Elevated levels of stress hormones, such as cortisol, can indeed make the body more vulnerable to chronic diseases by weakening the immune system and contributing to conditions like heart disease and diabetes. Telomeres actually shorten with each cell division, which limits cellular replication and is associated with aging. The stiffening of body tissues, such as arteries, actually contributes to the aging process and related health issues, not retards it. Elevated levels of free radicals in the body are associated with an increased risk of developing heart disease, not a lower risk, due to oxidative stress damaging cells.
