The price of ambition

There is always a price to pay for ambition. It might be all the late nights and overtime to secure that promotion. Maybe it was all the extra study that ate into your weekends. How many holidays have been used to catch up on all the stuff you should have done but couldn’t because you put it on hold, which meant you never had the downtime you needed to reset?

And this sort of slow burn erosion has led to you functioning on cortisol to meet those demands, but the problem with that is it has led directly to the brain fog, the loss of motivation, the loss of curiosity, the loss of your sex drive, and the direct hit your health has taken, not just mentally but also physically.

What cortisol is actually for

Most people think stress is the problem. I don’t. I think we’ve become so used to blaming stress that we’ve stopped asking a more useful question: what is actually happening inside the body?

My way of thinking about it is simple. Every day places demands on us. Some are physical, some are emotional, some are psychological. A demanding meeting, a poor night’s sleep, an illness, an intense workout, caring for a loved one, an exciting opportunity or even planning a wedding all ask something of the brain and body.

Each demand prompts the brain to decide what is needed. If more energy, focus or vigilance is required, it triggers the release of cortisol. That’s exactly what cortisol evolved to do. It isn’t the villain of the story; it’s one of the body’s most important adaptation hormones.

Where the rhythm breaks down

The problem isn’t that cortisol is released. The problem is that modern life rarely allows the system to finish one response before the next demand arrives. Cortisol is triggered again and again, until its natural daily rhythm begins to break down. And that is the shift almost nobody notices happening, because each individual demand looks reasonable on its own. It’s the fact that they never stop coming that does the damage, not any single one of them.

This is where I think the conversation needs to change. Rather than asking, “How do I reduce stress?”, I think we should be asking, “Are the demands I’m placing on my body greater than my capacity to recover?” That one question moves you from fighting a feeling to looking at something you can actually measure and change.

That’s the basis of what I call the Demand and Capacity model. When demand is balanced by recovery, cortisol rises when it’s needed and returns to its natural rhythm afterwards. That’s a reset, and it’s what a healthy day is supposed to look like. When demand repeatedly outstrips your capacity to recover, cortisol is triggered again before it has had the chance to settle, and the rhythm stops righting itself.

What happens when it doesn’t reset

Left like that, the disruption starts to reach the very brain circuits responsible for keeping you calm, motivated and thinking clearly. The threat side of the brain grows more dominant, while curiosity, reward and motivation begin to fade. That’s the fog, the flatness and the lost drive, not signs that something is wrong with you, but the predictable result of a rhythm that has not been allowed to reset in a very long time. Your sex drive tends to go the same way, and the physical toll follows, the creeping blood pressure, the sleep that no longer restores, the body catching everything going, because a body that is still running on demand quietly puts its ordinary repair work to one side.

Demand is not the enemy. A life without demand would probably be a life without growth, purpose or achievement, and the drive that got you here is not something to apologise for. The trouble begins only when demand consistently outpaces recovery, because that is the point at which the body’s most useful adaptation hormone starts becoming part of the problem rather than part of the solution.

Why the holiday works, and why it doesn’t last

The holiday works because it hacks through all those expectations that have sucked your capacity dry. A different environment, with time to be free from the usual demands, whether that’s days out exploring, enjoying good food at a leisurely pace or finally doing all those things you’ve been meaning to do but kept putting off. The reason it works is that it allows a world of different sensory input to flood in, bringing curiosity back online as your imagination explores a new vista. Your amygdala has a whole new set of data to process and it can’t keep up with the part of you that’s simply enjoying the day. It allows you to regain capacity, shed some of the load and give yourself the mental breathing space you’ve been missing.

That gives you the capacity to meet the demands when you return to work. For a while. But the reality is that recovered capacity only lasts so long before those same demands begin overwhelming you again, unless you deliberately build in brakes that interrupt the patterns driving cortisol. I promise you, there isn’t a hidden grail. You do, however, have to make small changes to your day.
