Kelly McGonigal is a health psychologist who discusses stress in her TED talk. She says that she used to see stress as an enemy, but she has changed her perspective. She cites a study that tracked 30,000 people throughout a year. In the study, people who had a high level a stress and also believed stress was bad for your health were 43% more likely to die, but people who had high levels of stress and did not consider stress to be bad for you did not have a higher rate of death. The study estimated that over the eight years they tracked deaths, 182,000 people died prematurely from believing stress is bad for you. She also discusses the social stress test which involves a speech and a math test while people are giving negative feedback. People who viewed their body’s responses as helpful were less stressed out and their physical stress response changed. Normally, people’s blood vessels constrict when under stress which is bad for the person’s health, but if a person saw their stress as helpful, their blood vessels did not constrict.
She then discusses oxytocin which is a stress hormone that promotes social contact. In the stress response, it directs you to find support. It is an anti-inflammatory hormone, and it helps heart cells to regenerate and heal from damage from stress. The benefits of this hormone are increased from social support. She then discusses another study that tracked 1,000 individuals. They found that every major stressful experience increased the rate of dying by 30%, but the people who spent time with others found no stress-related increase in dying. She concludes that choosing the way we view stress and act can change our lives for the better.
I really enjoyed this TED talk. I thought the speaker was credible since she is a health psychologist and backed her claims up with scientific studies. I think for me to fully believe her claim that your perception of stress can change your physiological reaction to it, I would need to see more studies done, but she points out something really interesting that I had never considered before. I found the message to be reasonable, and I want to believe her claim. It seems evolutionarily beneficial for the stress response to help, rather than to hurt you, and I thought the studies she cited helped her claim to seem reasonable. She did not discuss how these findings may differ for people with anxiety or depression, and I would imagine that having a mental disorder would make it much more difficult to simply change the way you view stress.
I definitely want to try having this more positive outlook on stress! I find myself being so stressed out that I become stressed about having stress, which is a cycle I would like to break out of. There is no harm in viewing stress from a more positive angle, and I hope this helps me to use stress to my advantage.
