Science Explains How Stress Damages Your Memory (And 5 Ways to Get It Back)

Our brain is a pretty amazing thing, no doubt. Weighing in at just over three pounds, the brain generates so much energy that it could power a low-voltage light bulb. It is capable of cellular growth throughout life, This almost superhuman ability is known as neuroplasticity . Stretched out, the number of blood vessels in your brain would extend over 100,000 miles – a distance capable of circling the earth four times! Amazing organ. But not without some flaws. Take for example the stress response. The stress response is vital to human survival. Without it, we wouldn’t bother safeguarding ourselves in life. It doesn’t take much brainstorming (unintentional pun) to think of ways this would be problematic. “Oh, an oncoming bus? No problem…” The End. While our natural stress response – sometimes known as the fight-or-flight response – has been good to us throughout evolution, it has some kinks. For one, we’re not jumping away from every moving bush, fearing it may be a leopard or tiger. Despite the disappearance of predators, our brain is still capable of reaching “high alert” lickity-split. All of that intelligence, all of those remarkable neurons, all of those years of evolution, and our brain still can’t tell the difference between real and perceived threats! But don’t worry, because it gets worse (before it gets better!). Stress and Brain Function Our brain and body are not designed to sustain a constant state of alert. When in a state of high alert, nearly all of your energy is redirected to your brain and muscles, which is fueled by the stress hormone cortisol. In turn, too much cortisol can damage a vital part of the brain called the hippocampus (pronounced “hippo-camp-us”). Cortisol has been shown to damage and kill cells in the hippocampus, the brain area […]
