Is Overwork Changing Your Brain?

Feeling overworked? You’re not alone—and it might be doing more than just leaving you drained.

We’ve known for years that overwork causes stress. But new research shows it also changes the brain. Yes, really—working too much can shift how your brain functions, and not in a good way.

A recent article in CNN Health shared results from a study that looked at people working 52 hours a week or more. What did they find? Big changes in parts of the brain that control how we think and manage emotions.

Let’s break it down.

Emotional regulation takes a hit.

The study found changes in brain areas that help with emotional control. When you’re overworked, it’s harder to stay calm under pressure, handle conflict, or bounce back from frustration. That’s tough for anyone, but especially if you’re leading a team or making big decisions.

Cognitive function slows down.

Overwork impacts the middle frontal gyrus—a part of the brain that helps with memory, focus, and problem-solving. So if you’ve noticed you’re more forgetful, distracted, or struggling to express yourself clearly, the long hours could be to blame.

Self-awareness fades.

Another area, the insula, helps us understand ourselves and how we relate to others. It’s linked to emotional intelligence. When overwork clouds this part of the brain, we lose touch with what we need, how we’re really feeling, and how our actions affect others.

So what can you do about it?

This isn’t about bubble baths or a weekend golf game—though those can help, too. It’s about using your emotional intelligence in a deeper way. That means checking in with yourself regularly.

What’s working? What isn’t? Why?

Maybe you realize your priorities have shifted, or that some tasks no longer match what you value. Small changes—like delegating, setting firmer boundaries, or adjusting your schedule—can make a big difference.

It’s also important to recognize your stress signals. Knowing your tipping point can help you pause before burnout takes over. And when you speak up for what you need, it sets a healthier tone in all your relationships, not just at work.

You can’t lead well when you’re running on empty. And you can’t connect with others if you’re disconnected from yourself.
