Why We Get Anxious (And What To Do About It)

Obviously, a lot of us are feeling anxious these days, with lingering political uncertainty on top of the pandemic on top of everything else in our lives.

Of course, some of that anxiety – and related feelings of caution, concern, and uneasiness – is useful. It’s certainly understandable. But worrying again and again about things that are out of control just creates needless suffering in ourselves. Worse, feeling on edge all the time makes us less able to cope with the challenges we can do something about.

All of this leads to an interesting question for scientists and healthcare professionals: Why are we like this? And what can we do about it?

In an evolutionary framework, anxiety is adaptive. Our ancestors who could experience a sense of alarm at a threat, or at the risk of losing rewards, were more likely to survive than those who could not. These creatures lived and reproduced more often than creatures who were not as worried. The blissed-out caveman or early mammal that didn’t pick up the slither in the bushes got eaten.

So, anxiety helps us do the fundamental things any animal needs to do if it wants to see the sunrise: avoid threats, approach rewards, and attach to others. Some of the ways it does this are pretty obvious, including in the classic fight-flight-freeze reactions. But some are less obvious. A little anxiety, for example, helps us remember to get some more milk at the store, or to get that work task done on time.

Anxiety also helps us maintain and strengthen our relationships. For instance, young children get anxious at being separated from their parents, which motivates them to stay close – which is safer for them today much as it was back in the Stone Age. With my wife, if I can start to tell that she was rattled or hurt by something I said, the uneasiness and even alarm that this stirs up in me prods me to reach out to her and find out what went wrong, and how to make it right.

And all this happens in the blink of an eye. The brain labels a phenomenon: that rustling in the grass is a snake! Two parts of the brain in particular, the amygdala and the hippocampus in the limbic system, quickly categorize it as pleasant (approach!), unpleasant (avoid!), or neutral (move on). And based on this labeling, the brain initiates a two-pronged reaction through both the autonomic nervous system and the endocrine (hormonal) system.

For example, the sympathetic branch of the nervous system could speed up the heart to bring more blood to muscles for fighting or fleeing, and meanwhile the hypothalamic – pituitary – adrenal axis could start sending a cascade of adrenaline and cortisol coursing through your veins.

Now, how can we apply all this to become more skillful at dealing with things that make us fearful, anxious, worried or alarmed?

First, we can accept and love the parts of ourselves that feel frightened. Often we’re ashamed of these and scorn them. What happens when you befriend them instead? These instincts may not always be helpful, but they’re here to help.  Everyone has them. It’s evolutionarily helpful to be afraid sometimes. This is natural.

Most importantly, don’t beat yourself up for having a hard time. These are hard times.

Second, see if you can get to know another part of yourself, too: the part of you that does know how to cope.

Here’s how that works—you can try it right now if you like. Step back and recall a time you were determined and hung in there and got through a tough situation or period in your life. Take a moment to get in touch with what this felt like—in the body as well as in the mind. What does it feel like to be determined? To be patient and enduring? To make a good plan and take skillful action?

By calling up these states of being that are at the heart of resilience, you “light up” their underlying neural circuitry. And when you repeatedly activate this neural circuitry, you strengthen it through what’s called “experience-dependent neuroplasticity” – which means, in plain English, that you can hardwire greater resilience into your own brain. This really works.

Lastly, I’d like to finish with a brief passage from one of my favorite books, Dune, by Frank Herbert:

I will face my fear.

I will permit it to pass over me and through me.

And when it has gone past, I will turn the inner eye to see its path.

Where the fear has gone there will be nothing.

Only I will remain.
