  • When I need to unwind, there's nothing I love more than an "experience."


  • Snorkeling in the Great Barrier Reef, zip-lining or even just riding roller coasters at Coney Island.


  • These aren't relaxing activities by any stretch.


  • In fact, they get my adrenaline pumping, so physiologically I'm experiencing "stress," but I still enjoy them, and I still feel better after them.


  • Stress usually gets a bad rap.


  • Some studies have linked chronic stress to depression, obesity, and heart disease.


  • But my happy experiences with briefly stressful activities got me thinking...


  • Are there times when a little stress can be good for us?


  • I'm Vanessa and you're watching BrainCraft.

    私バネッサが、今日も BrainCraft をお送りします。

  • We explore the psychology in your every day life.


  • Now, scientists have actually done a lot of studies on the potential benefits of short-term, acute stress.


  • A group of researchers at the University of Wisconsin wanted to know if the stress hormone cortisol affects how well people learn and remember.


  • A study that's relevant for students cramming for exams all over the world!


  • Now, cortisol is naturally released when our "fight or flight" systems are activated.


  • Chronically high levels of cortisol are linked to high blood pressure, heart disease, digestive issues, anxiety and depression.


  • But in spurts, cortisol works as a signal to increase dopamine, which improves perception and attention.


  • In this study, researchers gave participants a placebo, 20 milligrams, or 40 milligrams of cortisol.

    この研究では、被験者には偽薬、20 ミリグラムのコルチゾール、そして 40 ミリグラムのコルチゾールが投与され、

  • Then they gave them a list of words to memorize.


  • Two days later, people who received a 20-milligram dose did the best job of recognizing the words that they'd been asked to memorize.

    2 日後に検査をしたところ、20 ミリグラムのコルチゾールを投与されたグループが単語の記憶タスクの結果が最も優れていました。

  • So a little stress, but not too much, can actually help us learn.


  • Beyond a boost in memory, researchers were curious about how these small bursts of stress could impact our relationships with others.


  • Would stress bring us together or push us apart?


  • So, they put people through stress-inducing tasks, and then measured their social behaviors compared to control participants.


  • The stressed participants were more trustworthy and more likely to share in a game where they could compete or cooperate to win money.


  • This result is supported by how communities respond to disasters in the real world.


  • Research shows that people are more cooperative, open, and giving after a disaster.


  • Acute stress can bring communities together too.


  • And the way that we think about stress can have a huge influence on the way it affects us.


  • People who view stress as potentially beneficial are less negatively impacted by adverse life events than people who think stress can only be bad. -[Stressfull events can help me grow as a person]


  • So, think about presenting or speaking in front of a crowd.


  • Everyone has a physiological stress response to public speaking: cortisol levels and heart rate go up, you might feel a little nauseous or jittery.


  • Would you describe this as anxiety or excitement?


  • The physical sensation is the same, but someone who describes that feeling as "excitement" is more likely to enjoy public speaking than someone who describes it as "anxiety."


  • Simply learning that symptoms of stress may be beneficial, and can lead to healthier responses to stress in the future.


  • So while chronic high stress is known to be harmful, short-term, acute stress isn't necessarily bad.


  • Instead of focusing on the negatives, think about a time that you enjoyed stress, like during a horror movie, or while riding a roller coaster.


  • Think of times when stress helped you cram for an exam or when a stressful experience brought you closer to a friend or colleague.


  • Reframing your thinking about stress can have real benefits for how you experience day-to-day challenges.


  • So instead of being stressed about stress, try to focus on how you can use it to your advantage!


  • Now, if you're trying to stress less, one thing that can help is password manager.
