...also common among Holocaust survivors, rape victims and soldiers suffering from PTSD. The difference seems to be that people with PTSD are much more sensitive to cortisol at even these low levels than those with burnout. "We used to blame everything on high cortisol," says Rachel Yehuda, a neurochemist and PTSD expert at the Mount Sinai School of Medicine in New York City. "Now we can blame things on low cortisol as well...
...great performance of Hamlet-all can unleash the same stress hormones as do less uplifting experiences, sending the blood pressure soaring and causing the heart to palpitate madly. But who among us would give them up? "A certain amount of stress is a positive and pleasurable thing," says Neurochemist Barchas. "It leads to productivity in the human race...
...massive dose of acute stress," says Dr. Fred Goodwin, director of intramural research at the National Institute of Mental Health (NIMH). "Where we fall down is in our ability to mobilize for recurrent stressful episodes." Today the physiology of stress is being worked out in extraordinary detail. Says Neurochemist Jack Barchas of Stanford: "We have learned that even subtle behavior can markedly influence biochemistry...
...impact of major life events on health has been reconfirmed many times. A study published earlier this year in the British medical journal Lancet reported that the incidence of fatal heart attacks rose sharply in Athens in the days following the 1981 earthquake there. Stanford Neurochemist Barchas has found that a high score on the Holmes-Rahe scale is linked to elevated levels of the hormones associated with stress: adrenaline (which scientists have re-christened epinephrine), norepinephrine and beta-endorphin. An Australian study of bereavement has shown that eight weeks after the death of their spouses, widows and widowers have...
...pathways shown in the illustration above some 40 years ago. Since then, scientists have found that stress provokes a number of even subtler chemical changes in the body that may have profound effects on health, both physical and mental. "There is a constant intertwining of stress systems," says Stanford Neurochemist Jack Barchas. "It's much like a symphony...
