How Exercise Benefits Your Brain

Japanese scientists have uncovered that the body overcompensates for the drain of physical activity by pumping the brain full of glycogen, a carbohydrate that acts as an energy store. 

What's the Latest Development?


Japanese scientists have just uncovered why exercising gives your brain such a powerful pick up. By examining the brains of animals on an exercise regimen, they saw that physical activity severely drains the energy resources that neurons need to fire, which in doing so provide for functions like thought and memory. Over time, however, the body begins to overcompensate for the resource drain by pumping higher-than-normal levels of glycogen, or stored carbohydrates, into higher-order regions of the brain like the frontal cortex and the hippocampus. 

What's the Big Idea?

Until ten years ago, scientists thought the brain subsisted entirely on glucose, or blood sugar. But then researchers found specialized brain cells, now known as astrocytes, which support neurons by storing carbohydrates near by. When neurons are sufficiently deprived of energy, through exercise or hunger, "their neighboring astrocytes undergo a complex physiological process that results in those cells' stores of glycogen being broken down into a form easily burned by neurons."

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.
