Moments of Acute Stress Can Cause Molecular Alterations in Immune Response

Findings come from study that involved participants jumping out of planes —

Chronic psychosocial and emotional stress has well-documented negative effects upon the human immune system, measurably increasing the risk of disease. Much less is known about the health effects of acute but transitory episodes of stress, such as jumping out of an airplane. Do these panic-inducing moments also raise the risk of stress-related conditions and disorders, such as cardiovascular disease, sleep dysfunction, impaired wound healing, depression and obesity?

A team of researchers at University of California, San Diego School of Medicine, Stony Brook University in New York and elsewhere addressed that question by asking study participants to literally jump out of a plane, taking blood samples before and after to measure key immune response indicators.

Their findings are published in the March 4 issue of Brain, Behavior and Immunity. … Read the Full Story from the UC San Diego Newsroom
