Try High-intensity Interval Exercise: Your Brain Might Thank You
Credit: iStock Imagine burning 30 percent more calories in half the amount of time you usually spend working out—and continuing to burn calories after the workout ends. High-intensity interval exercise (HIIE)—a type of workout that alternates bursts of intense cardiovascular exercise with brief breaks—does just that. A recent study from Brazil suggests that HIIE does … Continue reading Try High-intensity Interval Exercise: Your Brain Might Thank You
Spotlight On: The Nervous System
Credit: iStock Of all the organs in our bodies, the brain is the most complex and deeply tied to what makes us human. Billions of nerve cells (neurons) in the nervous system make trillions of connections that are the basis of our thoughts, feelings and actions. Our genes make sure our nervous system is generally … Continue reading Spotlight On: The Nervous System

It is the buildup of CO2 more than the lack of fresh oxygen that makes you feel a strong urge to inhale when you hold your breath—like … Continue reading Time to Breathe

The word homeostasis comes from the Latin roots homeo, meaning similar, and stasis, meaning condition. Homeostasis is the ability of the body to keep everything in balance. It’s important for the body to always monitor what is going on, correcting functions that are out of balance and bringing them back to normal. Homeostasis and regulation … Continue reading Spotlight On: Homeostasis
Running on Empty: No Oxygen Needed!
Take a deep breath in. Now breathe out. Each time we breathe, oxygen enters the bloodstream to keep our organs alive and working. When oxygen can’t get to our body’s tissues, they begin to fail. This is true of all organs, but most of all the brain. In conditions like stroke and cardiac arrest—when the … Continue reading Running on Empty: No Oxygen Needed!
