“Almost everything will work again if you unplug
it for a few minutes, including you.”
Anne Lamott
Rest is not a reward. It is a biological requirement.
I want to start there, because so much of what I see in my clinical work traces back to a single, deeply embedded cultural lie: that stillness is a form of failure. That if you are not moving, producing or optimizing, then you are falling behind. I hear it from the executive who cannot sit through a meal without checking her phone. I hear it from the mother who feels guilty the moment the house goes quiet. I hear it from the young professional who describes rest as something he will do “when things slow down”, which, of course, they never do.
This piece is for all of them. And perhaps for you.
What Chronic Rushing Is Actually Doing to Your Brain
Most people know, somewhere below the surface, that they are moving too fast. They feel it in the tension that takes up permanent residence in their shoulders, in the racing quality of their thoughts even at midnight when nothing is being asked of them.
But the cost runs deeper than that felt sense of exhaustion.
When we exist in a state of chronic time pressure, we are not simply tired; we are physiologically dysregulated. Sapolsky’s decades of research in stress neurobiology have demonstrated that glucocorticoids, particularly cortisol, are released in response not only to actual physical threat, but to perceived threat, including a packed calendar, a difficult email, or the anticipatory anxiety of tomorrow’s demands. In the short term, this hormonal response is adaptive. Cortisol sharpens focus, improves memory consolidation, and mobilizes energy. But sustained elevation, the kind that comes from living in permanent urgency, puts neurons in a state of chronic emergency, depleting their function and, over time, measurably shrinking the hippocampus, the brain structure central to both memory and emotional regulation.
The brain under chronic stress cannot access its most sophisticated capabilities. The prefrontal cortex, your seat of judgment, empathy, creative reasoning, and nuanced decision-making, is suppressed by prolonged cortisol exposure. This is not a metaphor. It is a structural, neurochemical reality. The breakthroughs do not come when you are sprinting. They come in the shower, on a slow walk, in the quiet space between tasks, because that is when the prefrontal cortex can actually work.
The Brain Does Not Rest When You Rest
Here is what changed my understanding of this permanently.
For years, neuroscientists assumed that the brain was essentially idle during rest, in that the mind wandering, the daydreaming, the unfocused gaze out the window, were forms of cognitive downtime. Research published using fMRI dismantled that assumption entirely, demonstrating that what is known as the Default Mode Network (DMN), a distributed set of brain regions most active during wakeful rest and mind-wandering, is far from quiet. During these so-called idle states, the brain is engaged in some of its most sophisticated work: consolidating memory, generating insight, constructing future scenarios, and deepening emotional and moral understanding.
Daydreaming, it turns out, is not wasted time. It is neurologically essential!
The researchers also documented strong associations between healthy DMN activity and cognitive capacities including reading comprehension, divergent thinking, and the processing of social emotions with moral weight. The capacity for empathy, for meaning-making, for complex ethical reasoning: these depend on the brain having space to turn inward. Which means that when we eliminate rest, we are not simply tired. We are quietly dismantling the very capacities that make us good at our work, our relationships, and our lives.
The Sleep Debt We Are Not Talking About Enough
Sleep is where this conversation becomes most urgent.
The research is now unambiguous: sleep deprivation more profoundly than almost any other single lifestyle factor. Studies consistently show that even modest sleep restriction, reducing nightly sleep by 90 minutes over several weeks, produces significant declines in working memory and response inhibition in otherwise healthy adults.
What concerns me clinically is not the person who pulls one late night. It is the person who has quietly normalized six hours, who no longer remembers what it feels like to be rested, and who interprets their chronic flatness or irritability as a personality trait rather than a physiological state. Sleep deprivation does not just make us tired. It makes us measurably less empathetic, less creative, less accurate in reading social cues, and significantly more reactive to ordinary stressors. We become, in a very real neurological sense, a lesser version of ourselves, and we rarely connect the dots.
Seven to nine hours of sleep is not an indulgence. It is the foundation upon which every other function in your life is built.
The Symptoms We Are Misreading
In clinical practice, I routinely see the downstream effects of lives lived at unsustainable velocity. They arrive looking like other things:
Persistent fatigue that sleep does not seem to resolve. Irritability that feels disproportionate. Difficulty concentrating, or a growing inability to make simple decisions. A sense of disconnection from yourself, from the people you love, from work that once felt meaningful. Physical symptoms: tension headaches, digestive irregularities, a body that is quietly keeping score. An anhedonia, a loss of pleasure, in things that used to bring joy.
These are not character flaws. They are not ingratitude. They are the predictable consequence of a nervous system that has been in activation for too long without adequate recovery. The body is not broken. It is doing exactly what it was designed to do under chronic stress. The question is: will we listen to it?
How to Begin: Practically
I am not in the business of prescribing a complete life overhaul. What I know from working with people is that sustainable change is built through small, consistent, intentional acts rather than dramatic transformations. Here is where I would start:
Build one deliberate pause into every day. Five minutes. No phone, no task, no agenda. Just you and the present moment. It will feel uncomfortable at first. That discomfort is data; it tells you how long you have been running.
Eat one meal this week without a screen. Presence at the table is one of the oldest practices in human culture, and the research on mindful eating, covering its effects on digestion, satiety, and emotional regulation, is consistent. It still works. It always has.
Say no to one thing that exceeds your current capacity. This is not selfishness. It is sustainability. Every yes to something depleting is a no to something that nourishes.
Protect your sleep as non-negotiable infrastructure. Not the first thing you sacrifice when life gets busy. The thing you protect precisely because life is busy.
Redefine what counts as productive. A deep conversation. A slow morning. A long walk without a destination. These are not wasted hours. In neurological terms, they may be some of the most productive hours of your week.
Notice the guilt and question it. When stillness feels wrong, ask yourself where that belief originated. Is it genuinely yours, or is it an inherited cultural message that confused worth with output? Most of us, if we are honest, absorbed the latter.
A Final Word
You cannot keep pouring from an empty vessel. This is not a metaphor about self-care. It is a statement about physiology.
The pace that many of us have quietly normalized is not ambition. It is survival mode wearing ambition’s clothes. Slowing down is not giving up. It is not falling behind. It is the deliberate act of choosing to live, and function, and feel, and connect, at a pace that is actually sustainable. Not just for your career, but for your nervous system. For your relationships. For the parts of yourself that deserve to exist beyond your productivity.
You do not have to do this work alone.
