If You Need an Excuse to Go for a Walk, Science Just Provided One

Want to improve your mood? This study recommends you get walking, even for a short time, and even if your surroundings aren't picturesque.

If you have ever wanted a pick-me-up and an excuse to move a little, you finally have it. A new study from Iowa State University has found that simply walking for a short period of time can improve mood substantially. This effect remained even when attempts to make the walk less pleasant were instituted. Jeffrey Conrath Miller and Zlatan Krizan, professors in psychology, published their study in Emotion and suggest that walking by itself, rather than setting, pace, or other external factors, is the key element in the resulting mood enhancement. 

The study involved 232 undergraduate students who were first asked to either sit or walk around during a viewing of a familiar and unfamiliar environment. During the second phase of the study the participants were asked to tour a “drab” setting, again while either sitting or walking. In the final section, they simply walked on a treadmill in a small controlled room. Mood was measured by means of the PANAS (Positive And Negative Affect Schedule) test at various points before and after the activities were completed.

The results were clear: merely walking dramatically improved the moods of the students involved, especially when compared to the students who did a similar activity while seated. The effect remained even when the environment changed to the duller possibilities.

In the second part of the study, the researchers decided to add another element to see how strong the effect was: they tested whether the mood boost measured before could withstand the knowledge of something unpleasant while walking. Being that the test subjects were students who were participating as part of a research-participation course requirement; the dread-causing idea was:

“After the tour you will have 10 minutes to write an essay that is 2 full pages in length about the structural elements of the building”.

Even this terrifying idea, which was intended to sour their opinion of the walk they were taking, was unable to reduce the positive gains of walking by much, despite the expressed expectation by the subjects that they would feel worse. The students found out after their mood was measured that they also didn’t have to write the essay. This elation was not recorded.

The authors did, however, have to conceal the purpose of the actions from the subjects during the experiment to avoid corrupted data. Because of this they cannot say for certain that it was the walking that caused the improved mood, but they can rule out several other possible factors.

The idea that movement improves mood goes back to long ago. Charles Darwin himself supposed that: “Now with animals of all kinds, the acquirement of almost all their pleasures, with the exception of those of warmth and rest, are associated with active movements.” This study seems to support this. So if you want to feel better, get moving.

And if you need another reason to stretch your legs:

 

The “new normal” paradox: What COVID-19 has revealed about higher education

Higher education faces challenges that are unlike any other industry. What path will ASU, and universities like ASU, take in a post-COVID world?

  • Everywhere you turn, the idea that coronavirus has brought on a "new normal" is present and true. But for higher education, COVID-19 exposes a long list of pernicious old problems more than it presents new problems.
  • It was widely known, yet ignored, that digital instruction must be embraced. When combined with traditional, in-person teaching, it can enhance student learning outcomes at scale.
  • COVID-19 has forced institutions to understand that far too many higher education outcomes are determined by a student's family income, and in the context of COVID-19 this means that lower-income students, first-generation students and students of color will be disproportionately afflicted.

Masturbation boosts your immune system, helping you fight off infection and illness

Can an orgasm a day really keep the doctor away?

Sexual arousal and orgasm increase the number of white blood cells in the body, making it easier to fight infection and illness.

  • Achieving orgasm through masturbation provides a rush of feel-good hormones (such as dopamine, serotonin and oxytocin) and can re-balance our levels of cortisol (a stress-inducing hormone). This helps our immune system function at a higher level.
  • The surge in "feel-good" hormones also promotes a more relaxed and calm state of being, making it easier to achieve restful sleep, which is a critical part in maintaining a high-functioning immune system.
  • Just as bad habits can slow your immune system, positive habits (such as a healthy sleep schedule and active sex life) can help boost your immune system which can prevent you from becoming sick.
