Stress gets to everyone, but it could have a bigger impact than you think.
Stress can have devastating effects on our health and well-being, from the health of our cardiovascular and immune systems to our mental and cognitive fitness.
With the media constantly broadcasting that "stress kills," most of us know this. So here's a question for you: Why don't we give stress the respect it deserves? Why do we take it for granted, especially when managing stress is well within our control?
On the one hand, we're all familiar with stress. We use the word often - "My daughter is so stressed!" - and most of us experience stress on a regular basis. Maybe it's because we talk about it so much that we don't take it as seriously as we should. Everyone has stress, so why should I worry about it?
I think there's a reason we take stress for granted: because stress is elusive and difficult to grasp. It's invisible. You can't see it or touch it, and therefore it's hard to believe it could actually harm you. Stress can also seem psychological - more mental than physical, right? And if stress is in the mind, how can it get into the body and brain? But psychological stress affects physical wellbeing.
Here's a common example: you're stuck in traffic. There's nothing physically threatening about this - it's certainly not the same as being chased by an angry bear. But it's frustrating and associated with thoughts like "I'm never going to get home in time to make dinner" or "I'm going to be late for work and make my boss angry again." These are just thoughts, but just like the bear, they can trigger a stress response, which is very much physical.
The stress response begins with the release of hormones called cortisol and noradrenaline. Cortisol increases blood glucose to provide energy, and, if the stress lasts, stores that energy in the form of fat in the arteries and abdomen. Noradrenaline - also known as norepinephrine - causes your heart to race and your blood pressure to rise. In the short term, increased blood pressure and glucose are good things, helping you react efficiently to a threat and get out of harm's way. But in the long run, these same hormones that evolved to help can begin to hurt instead.
It's critical to understand that stress can have physical effects on you. Noradrenaline and cortisol can be secreted just by thinking stressful thoughts. Once elevated, they have an impact on both the body and the brain. Your health and memory suffers.
Next time you're stuck in traffic, count your breaths, turn on the radio, or listen to a book on tape. Whatever small efforts you make to control your stress, your body, brain, and memory will benefit.
