Our Best Thinking Starts Below the Neck

August 18, 2025

---

In knowledge work, we treat the brain like it’s the only organ that matters. Strategy lives in the mind. Decisions happen in meetings. Insight comes through screens.

We’ve been professionally trained to live from the neck up.

But the truth is more embodied than that:

Our best thinking doesn't start in our heads. It starts in our bodies.

And when our bodies are depleted, stressed, overstimulated, or ignored - our minds don’t rise above it. They mirror it.

We’re Not Just Tired from the Workload.

We’re Tired Because Our Systems Are Overdrawn.

We often say we’re tired. Unfocused. Mentally fried.

And the standard fixes? More sleep. Less caffeine. A better calendar.

But most of us aren’t struggling because of a lack of willpower or scheduling skill.

We’re struggling because there’s a disconnect between what our brains demand and what our bodies can sustain.

Consider this:

The brain makes up only 2% of body mass, but consumes 20% of the body's total energy, even at rest.

The quality of our thinking depends on how we support the entire system - not just how hard we try to focus.

The Myth of Mental Overdrive

Many of us grew up believing the mind could power through anything.

Push harder. Focus longer. Out-think the fatigue.

But science - and experience - say otherwise.

When our bodies are overloaded or under-resourced, our cognitive performance suffers. We don’t get smarter under pressure. We get reactive, impulsive, foggy.

We don’t solve problems faster - we repeat them.

Productivity Is Physical First

If we’re in roles that require clarity, empathy, or decision-making, our physical state isn’t background noise. It’s the main signal.

• Want sharper thinking in a meeting? We can prep our bodies, not just our slides.

• Want creative insights? Let’s start with blood flow, not brainstorming prompts.

• Want stronger leadership presence? We need regulation, not just rehearsal.

Our productivity isn’t purely cognitive. It’s chemical. It’s physical. It’s embodied.

Try This: Shift the Input, Not Just the Output

Before the next big task or conversation, pause and ask:

“What physical state do I want to be in to lead this well?” “What input does my body need to support what my brain’s about to do?”

Maybe it’s movement. Maybe it’s hydration. Maybe it’s five minutes of nothing.

Let’s stop treating physical needs as optional. They’re strategic.

We’re not just heads in meetings. We’re systems - intricately wired, deeply human, and at our best when we honor the whole of who we are.

When we treat the body like a partner instead of a passenger, we don’t just feel better. We think better.
