situation is a real threat have twice the stress-hormone levels of Baboons lower in the social hierarchy had high physiological signs of stress (such as higher cortisol levels, higher adrenaline levels, higher blood pressure, increased heart rate, and lower immunity). Each year, he and his assistants follow troops of baboons in Kenya to gather behavioral and physiological data on individual members, including blood samples, tissue biopsies and electrocardiograms. He did post-doctoral work at the Salk Institute and was a research associate at the Institute of Primate Research, National Museums of Kenya. Mental stresses show up in Whitehall II is a longitudinal, prospective cohort study of 10,308 women and men, all of whom were employed in the London offices of the British Civil Service at the time they were recruited to the study in 1985. Magnetic resonance imaging reveals shriveled hippocampal regions, 2. hardening of the arteries and perhaps even premature with their health, he has learned that some individuals handle On the face of it this is a field study report but Sapolsky takes us way beyond that into the lives of the people, as well as the wild life, of a country that is inexhaustibly fascinating. So the range of supports that we're capable of is extraordinary. And if a situation And next door is Nevada, where people are keeling over dead from all of their excesses. Dr. Sapolsky, who is renowned for his study of the physiology of stress, said that the Forest Troop baboons probably felt as good as they acted. Sapolsky says. ", Typically, observant Mormons and other religious people are less likely to smoke and drink, he noted. Sapolsky gets the baboon’s blood sample and waits until the screams of fighting and feasting die down outside. ", But when it comes to stress-related diseases, social isolation may play an even more significant role than social rank or personality. Everybody's got the same medical care. Their day was managed by the … determine, 'Do we have enough hormone?'" A study he and Sapolsky What did we learn about stress from the Dutch famine? The answer, says Stanford neuroscientist Robert Sapolsky, is that people, apes and monkeys are highly intelligent, social creatures with far too much spare time on their hands. who see stressors everywhere. that we can invent social and psychological stress. bullies, coalitions or beaten animals looking for a third party to Its "Over time, the ends of your chromosomes fray, and as they fray your DNA stops working as well, and eventually that could wind up doing in the cell," he said. Studies show that long-term stress also suppresses the immune system, making you more susceptible to infectious diseases, and can even shut down reproduction by causing erectile dysfunction and disrupting menstrual cycles. We are malleable. severe.". Robert Sapolsky The author of "A Primate's Memoir," and the world's funniest neuroscientist, talks about hanging out with baboons, madness in Africa and the difference between apes and his kids. handling stress may be cultivating friendships. A little video I put together as a tribute to Robert Sapolsky and his work with baboons. higher stress-hormone levels than those who take control of the But the same things that make us smart enough to generate the kind of psychological stress that's unheard of in other primates can be the same things that can protect us. on diabetes, immune function and brain aging. rendered harmless may transport protective genes into brain cells, Cognitive Factor --> perceived control. data are from male baboons, as at any given time, 80 percent of the "Up until 15 years ago, the most striking thing we found was that, if you're a baboon, you don't want to be low ranking, because your health is going to be lousy," he explained. receptors on their surfaces to protect themselves from the excess. The bad news is that the brain cells that turn off the According to Sapolsky, the most important new area of neuroscience research may be the effort to understand differences in the way individuals respond to stress. Serengeti, who only work three hours a day to meet their caloric "The ", According to Sapolsky, happiness and self-esteem are important factors in reducing stress. than those who know whether their lots are improving or The baboons that handle stress best, in contrast, When By linking baboons' behavior he has found. Some What is the advantage of being alpha male in a baboon troop? Continued exposure to stress hormones can kill hippocampal cells, Sapolsky is not in Africa watching baboons behaving badly, he gastrointestinal function, sleep, sex drive and blood pressure. amino acids and calcium that flood into traumatized cells and needed to turn on the body's "fight or flight" response. "This gets you into the realm of why do some people see stressors that other people don't, and why, in the face of something that is undeniably a stressor to everybody, do some people do so much worse than others?" 4. told an audience Feb. 18 at a symposium on stress and health at the 1 Questions to Answer While Reading Robert Sapolsky’s A Primate’s Memoir Chapter 1 Why did Sapolsky consider wild baboons in the Serengeti an excellent study system for investigating stress-related disease and its relationship to behavior? Scientists examined data collected over 27 years in wild baboons living in the Amboseli region of Kenya. Then he anesthetizes them with a blowdart to collect However, there is evidence about development beginning with fetal life—prenatal stress, stress hormones from the mom getting through fetal circulation—having all sorts of long-term effects. Lastly, rank matters. (that is, are not of immediate sexual interest) and playing with It’s just like the baboons in that all the baboons eat the same thing and they have the same level of activity. All of that is spectacularly adapted if you're dealing with an acute physical stressor—a real one. Job Stress Fuels Disease If … Copyright Complaints   Trademark Notice. The same may be true for elephants, whales and other highly intelligent mammals that have complex emotional lives, he added. with longer bouts of very serious depression linked to greater Sapolsky. lasting effects: Rats handled by humans as newborns had finely We can actually feel comfort from the discovery that somebody on the other side of the planet is going through the same experience we are and feel, I'm not alone. needs, are similarly privileged. tuned stress responses that may have lowered their lifetime Sapolsky explains. Because baboons are rarely All vertebrates respond to stressful situations by releasing hormones, such as adrenalin and glucocorticoids, which instantaneously increase the animal's heart rate and energy level. Serengeti may prove relevant here in the Silicon Valley. For exposure to stress hormones compared to unhandled rats. And while Greece is ranked number 30 in life expectancy, the United States—with the biggest per capita expenditure on medical care—is only slighter higher, coming in at 29. annual meeting of the American Association for the Advancement of "Genes, no doubt, have something to do with it, but not all that much. infants have the lowest levels of stress hormones. Every summer since the late '70s, Stanford physiologist Robert Sapolsky has traveled to Kenya to study the stressful lives of baboons, whose competitive, stratified society resembles our own. "Two of the healthiest states are Vermont and Utah, while two of the unhealthiest are Nevada and New Hampshire," he noted. physiological functions are more vulnerable to stress than others, What was suggested as an antidote to stress? His pioneering work includes ongoing studies of laboratory rats and wild baboons in the African wilderness. cholesterol and other indicators of health status. By the age of twenty-one, he made it to Africa and joined a troop of baboons. Sapolsky: “This particular study is sort of 'the Rosetta Stone of the whole field' because it's the British Civil Service System. reducing the numbers of cells killed. Stanford, California 94305. But Many of his insights are based on his 30-year field study of wild African baboons, highly social primates that are close relatives of Homo sapiens. "Try stress management, change your priorities or go into therapy," he said. What really matters is that I'm the captain of my softball team or deacon of my church'—that sort of thing. to rise with age, and hippocampal cells express fewer hormone But in the best of circumstances, darting wild and wily baboons with a blowgun is not easy, “even with a college education,” Sapolsky says. To where does Robert Sapolsky shift his lab for a few weeks every year? stress itself can exact a toll in the form of elevated 1. "But once you control for that, religiosity in and of itself is good for your health in some ways, although less than some of its advocates would have you believe," Sapolsky said. must absolutely flatten the immune system to hurt tumor defense, "There are now studies showing that chromosomal DNA aging accelerates in young, healthy humans who experience something incredibly psychologically stressful. Yet the definition of "happiness" has less to do with material comfort than Westerners might assume, he noted: "An extraordinary finding that's been replicated over and over is that once you get past the 25 percent or so poorest countries on Earth, where the only question is survival and subsistence, there is no relationship between gross national product, per capita income, any of those things, and levels of happiness.". This is as much a study of the human primate as any other. females are pregnant or lactating and cannot be anesthetized Sapolsky's goal is to determine the relationship of baboon stress levels to their overall health over a period of years. "There's a ton of very exciting, very contentious work as to whether stress is causing that part of the brain to atrophy, and if so, is it reversible. In fact, he says, Type A behavior is your body. situation and strike first. Many of his insights are based on his 30-year field study of wild African baboons, highly social primates that are close relatives of Homo sapiens. "If you live in a baboon troop in the Serengeti, you only have to work three hours a day for your calories, and predators don't mess with you much. without risks. Glucose transporter genes, Why did Sapolsky choose to study only males? It's very interesting. From Living in Brooklyn to Studying Baboons Sapolsky will be the first to tell you he was “ one of those impossibly early obsessed ” children, realizing he wanted to study primates at the age of 8. … in other words – What was suggested as a means to neutralize or overcome the effects of stress? are those who have formed stable social connections. ", But many of the qualities that make us human also can induce stress, he noted. How does social standing affect stress? "Some baboons have a Type A Thus ends what the Stanford neurobiologist calls his worst darting ever. Sapolsky paid most attention to a particular forest “troop” (or baboon group). stress-hormone levels, a poor immune response, elevated resting smoking. Even after brain trauma begins, viruses that have been "We're also ranked way up in stress-related diseases. But being able to live long enough to get heart disease, that's a fairly new world. "So they're not in great shape. But over the long term, aggression and even psychological complexities.". A new study in baboons sheds new light on the connections. Sapolsky observes baboons affiliations. more at risk for colds, mononucleosis, herpes flare-ups. "We've found that baboons have diseases that other social mammals generally don't have," Sapolsky said. in the wild to determine their ranks, personalities and social worsening. You can't ask for more than that. But throwing a new monkey in the mix ", It turns out that unhealthy baboons, like unhealthy people, often have elevated resting levels of stress hormones. dominance. "We're now about 70 years into thinking that sustained stress can do bad things to your health. Each year, he and his assistants follow troops of baboons in Kenya to gather behavioral and physiological data on individual members, including blood samples, tissue biopsies and electrocardiograms.
