Transcript

Welcome to Startup Brainframe, where we translate brain science for startups who wanna build the future. Today we're doing a deep dive into something every single founder knows, maybe too well. Stress. Mm-hmm. It's pretty much unavoidable. Right. But, uh, instead of just talking about how to avoid it, we're looking at it differently.

The idea is stress as a strategic asset channeling cortisol for high performance. Exactly. It's about turning that pressure that, you know, that constant hum into something useful like a power source instead of just dread. Precisely because if you're building something ambitious, stress will be part of the equation.

The real game changer is understanding how your brain actually reacts. Okay, so how does it react in a way that could be well strategic? It mostly just feels like overwhelm. Yeah, that's the common experience. But it starts with the basic neurobiology. When you face a challenge, could be a big pitch, a sudden code crisis.

Even just making payroll, all familiar scenarios. Totally. Your brain fires  up something called the HPA Axis hypothalamic, pituitary adrenal axis, fancy name. But basically it's the command center for stress response. And that leads to, that leads to the release of cortisol. Now cortisol gets this really bad reputation, you know, the stress hormone.

Yeah, definitely heard that. But here's the thing. In the short term, it's designed to be helpful. Really helpful. Actually how? Seems counterintuitive. Well, think of it like a biological performance boost. Cortisol sharpens your focus, makes glucose readily available, so you have quick energy and it ramps up your alertness.

Ah, okay. Like your brain saying, pay attention, this matters. Exactly. It primes you for action. The problem isn't cortisol itself, it's when that system gets stuck in the on position. Chronic fight or flight system failure, basically. That's a good way to put it. It's designed for sprints, not marathons. So it's the management of the stress response, not the response itself.

That's key. You got it. And that brings us nicely to the  idea of the stress curve. You might've heard of it, the Yerkes Dodson Law. Isn't it like an upside down U shape? That's the one. So imagine that curve on the far left. You've got very low stress. What happens then? Huh? Not much. Maybe boredom, lack of motivation, like a lazy Sunday precisely under stimulation.

Performance is pretty low. Not ideal if you're trying to, you know, change the world with your startup. Right? Definitely need some pressure. Okay, so as stress increases a bit, you move up the curve towards the middle, the top of that upside down U. The sweet spot. That's it. The optimal stress zone. This is where you feel alert, focused, energized.

You might even hit that state of flow. It's where peak performance often happens. Okay. I recognize that. Feeling. High stakes, but you're handling it. You're sharp, that's the zone, but push past that peak, keep ramping up the stress, and you start sliding down the other side. Exactly. You enter the high stress zone, overwhelm kicks in.

You feel reactive instead of proactive decision. Fatigue starts.  Yeah. Making bad calls, snapping at people. Performance just tanks. So the crucial insight here isn't that stress is bad, it's that some stress, the right amount of stress is actually necessary for you to do your best work. So we need it, but we need to control it.

Control it, or maybe surf it. Learn to ride that wave, those controlled bursts of cortisol we talked about. Yeah, they genuinely sharpen cognition, boost your working memory, help you prioritize. Okay, so surfing the stress curve, not drowning in it. I like that. How does cortisol actually enhance thinking though?

On a brain level. Good question. When it's in that optimal range, cortisol can actually stimulate activity in your prefrontal cortex. The thinking part of the brain, right? Planning logic. Exactly. That means clear thinking under pressure. You start seeing opportunities in what looks like chaos. It also engages the hippocampus Memory Center.

Yep. Helps you consolidate and recall critical information, stuff from meetings, articles you read, investor feedback, all vital, so it helps  you learn and adapt faster. And there's another piece, emotional salience. Balanced cortisol helps your brain tag what's important. Filter out the noise. Super valuable when you're bombarded with information like a built-in priority filter getting turned up, you could say that.

Now, contrast that with chronically high cortisol. Okay? What happens then? The downside, that prefrontal cortex function, it can actually decrease. You might become more impulsive, make rash decisions. Memory recall suffers blanking in a key moment. Ugh. Yeah. And you might misinterpret signals.

A neutral comment feels like harsh criticism. It scrambles your processing. So it's really about engineering your relationship with stress, not just pushing harder. That's the shift in mindset. It's not about avoiding pressure, it's about understanding how to use it. This makes me think those really tough moments in building a company.

Sometimes the clarity after pushing through them is intense. It wasn't fun. But something clicked. That's a perfect  example of the next idea. Stress combined with meaning equals drive. There's that great quote from Viktor Frankl. Man search for meaning. Yes. When we are no longer able to change a situation, we are challenged to change ourselves.

The most resilient founders often find purpose in the struggle. So seeing the stress, not just as a barrier, but as feedback. An opportunity. Exactly. Reframing it that way actually changes your brain's response. Cortisol stops being just a threat signal and becomes more like a signal for action. Turning tension into traction.

Beautifully put, it fuels you rather than drains you. Okay. This is all fascinating, but let's get practical. Yeah. What can founders actually do to, you know, surf this curve? Right. Actionable playbook. Time tip number one. When a big, new, stressful problem hits, don't react immediately. Resist that urge to make a snap decision, right then.

Why isn't speed important? It is, but problems often look way bigger and scarier up close in that initial moment of panic. Your  thinking isn't optimal then. Okay, so pause what? Then give it some time, a few hours, maybe even sleep on it. If you can use that buffer to gather more info. Talk to advisors. Just think, brainstorm options.

This lets you shift from that panic state back towards the optimal zone. Makes sense. Create some distance. Okay, tip two. Tip two is the overnight neuro detox. We touched on sleep, but it's huge, right? Things looking better in the morning. It's not just a feeling, it's neuroscience. During deep sleep, your brain has this amazing cleaning system called the glymphatic system.

Think of it like. Flushing the pipes flushing what? Cerebrospinal fluid washes away the metabolic junk that builds up during the day, including cortisol byproducts and inflammatory stuff linked to stress. Wow. A literal brainwash pretty much. Plus, your cortisol levels naturally drop during sleep while growth hormone peaks helping repair synapses.

And memory gets reindexed moving from short-term to long-term storage, often softening the emotional charge.  So you wake up with less emotional baggage and a cleaner slate. Exactly. Fresh perspective isn't just psychological, it's physiological powerful. Okay, tip number three, track your stress like data.

Seriously, like you track your KPIs. Stress isn't just random, bad luck. How do you track it? Journaling could be ask yourself, when did I feel that stress spike? What exactly triggered it? What was I doing , how did I react physically, emotionally? Look for the patterns. Yes, patterns will emerge. Maybe it's always after certain meetings or when you switch context too quickly or after getting negative feedback.

And once you see the pattern, visibility is power. Once you see it, you can design simple rules or interventions to break the cycle. Maybe it's scheduling buffer time or a specific routine after tough calls. Treating yourself like part of the startup experiment, you are your own internal operating system is critical to the whole venture.

Managing stress is part of optimizing that system. These are  fantastic actionable tips. Pause. Sleep track, understand the system, work with it. That's the core idea. And look, if you're feeling totally buried right now, remember the principle. Don't try to fix everything at once. Just start small. Just the first step.

Open the scary document. Draft one sentence of the hard email. Define the problem in one line, that initial action breaks. The inertia reminds me of Stephen Pressfield in the war's art. Oh, the resistance quote? Yeah, it's not the writing part. That's hard. What's hard is sitting down to write. What keeps us from sitting down is resistance.

Such a great line. It applies to so much in startups. Totally. Don't fight the whole war today. Just start. Resistance hates it when you just begin. Well said. And, uh, before we sign off, just a quick mention, we've actually launched a premium membership. Right. Tell folks about that. Yeah. So if you find these deep dives valuable, the premium option gives you eight extra ones each month.

That's two additional discussions like this every single week. So more brain science for startups. Exactly. It's a way to  go deeper, and frankly, it helps support Neoteq's mission to get this kind of neuro entrepreneurship insight out there. If that sounds interesting, check it out. Definitely worth considering if you're getting value here.

Yeah. Okay. That wraps up our deep dive on using stress strategically. Hmm. Thanks for taking the time to tune in on today's episode. See you in the next one.
