Over 90,000 tech layoffs have already been reported in 2026. Between 2024 and 2025, that number was already past 150,000. Teams are shrinking. Workload for the ones who stay is growing. And for the ones who don't — repeated rejection and prolonged job searches are quietly eroding wellbeing. Most of what I see written about this moment focuses on productivity. Output. How to use AI to do the work of three people now that three people are gone.

Nobody's asking the more interesting question: how do you sustain that?
The Real Problem Isn't Productivity. It's the Model.
We're asking people to operate at higher intensity, for longer periods, in increasingly isolated, AI-assisted setups. Whether you're employed and absorbing the workload of three people who were let go, or job hunting and treating the search like a full-time job, the cognitive demand is the same. High, relentless, and largely invisible. The standard response to that demand is to squeeze more out of the day. More hours. More hustle. More output. More prompts to AI. That model has a ceiling. And the ceiling is you. Your brain runs on biology, not willpower. Ignore that long enough and what you lose isn't just energy, it's decision quality, emotional regulation, creative thinking, the ability to prioritize under pressure. All the things that make senior tech professionals valuable in the first place. Sleep, nutrition, movement, and stress management aren't just wellness tips anymore. They're performance infrastructure. And treating them as optional is one of the most expensive mistakes I see high performers make.

What I'm Actually Doing to Stay Consistent
These aren't hacks in the hustle-culture sense. They're the seven things I've found to be non-negotiable for maintaining cognitive performance during a period of constant change. I'll explain the science behind each one, because understanding why something works is what makes it stick.

1. Sleep Prioritization
This is the baseline everything else builds on. During sleep, your brain clears metabolic waste through the glymphatic system, consolidates memory, and restores neural efficiency. Skimp on it and you're not just tired — you're cognitively impaired in ways that are genuinely hard to self-detect. Research consistently shows that sleep-deprived individuals rate their own performance much higher than it actually is. You don't feel as broken as you are. The target is 7–8 hours of quality sleep. Not as a nice-to-have, but as a non-negotiable baseline. One good night will do more for your output than the extra two hours you'd gain by staying up. If you fix nothing else, fix this first. It creates a domino effect: better sleep forces you to audit your evenings, your eating schedule, your wind-down routine. It pulls other habits into alignment.

Scientific study
A study by Van Dongen et al. restricted participants to 6 hours of sleep per night for 14 days. Cognitive performance declined progressively — equivalent to two full nights of total sleep deprivation. The striking finding: participants consistently rated their own sleepiness as having stabilised, even as their performance kept getting worse. In other words, you lose the ability to accurately perceive how impaired you are. The damage is real. The self-awareness isn't. Ref: Van Dongen HPA, et al. The cumulative cost of additional wakefulness. Sleep. 2003;26(2):117–126. doi:10.1093/sleep/26.2.117.

2. Batch Cooking
Nutrition is probably the most underrated cognitive performance lever in tech. The problem isn't that people don't know what to eat. It's that decision fatigue around food — what to make, when to cook, whether there's anything in the fridge — burns cognitive bandwidth that should be going to actual work. Batch cooking eliminates that. Cooking two or three times a week instead of daily removes dozens of micro-decisions from your week. It keeps you eating consistently instead of defaulting to whatever's fastest when you're already depleted. Less daily decision-making = more cognitive bandwidth for deep work. That's it.

3. Walking (This Isn't About Fitness)
Walking is one of the most effective, most sustainable, and most underused cognitive performance tools available to you. It's low-impact, accessible, requires zero equipment, and has a well-documented effect on blood glucose regulation, mood, and mental clarity. A 20-minute walk after lunch does more to flatten your afternoon energy crash than any amount of coffee. The target I use: 7,000+ steps a day as a consistent baseline. It's not a performance benchmark — it's a floor. A commitment to keeping the system running. For job-seekers especially: if you're spending 8 hours a day at a screen, this matters even more. Movement is the reset that keeps the next session sharp.

4. Strength Training
The research here is so consistent that I couldn't leave it off the list. Strength training is one of the few interventions with solid evidence linking it to improved memory and executive brain function — the kind of higher-order thinking that matters most in senior tech roles. Planning, prioritization, working under ambiguity. The cognitive domains that get squeezed hardest when pressure is high. The barrier most people hit is time. Which is why I want to be specific: you don't need a long session to get the cognitive benefits. Research suggests 15–20 minutes of intentional resistance work, done consistently, is enough to move the needle. Two to three sessions a week is the target I work around.

No equipment required. No gym membership needed. Just consistency and progressive overload — showing up and making it slightly harder over time. It's the highest ROI physical habit I've found for cognitive performance. The time investment is genuinely small for what it gives back.

Scientific study
A meta-analysis by Northey et al. reviewed the effects of exercise on cognitive function across 39 studies. Resistance training showed significant positive effects on cognitive performance — particularly in executive function and memory. Critically, benefits were observed across a range of session durations and frequencies, including moderate volumes. The takeaway: you don't need to train like an athlete to protect your brain. You need to train consistently. Ref: Northey JM, et al. Exercise interventions for cognitive function in adults older than 50. Br J Sports Med. 2018;52(3):154–160. doi:10.1136/bjsports-2016-096587.

5. Direct Sunlight Exposure
This one sounds simple because it is — and it's frequently ignored. Morning sunlight exposure helps anchor your circadian rhythm, which directly affects sleep quality, cortisol timing, and your parasympathetic nervous system — the rest-and-recovery state that enables clearer thinking and better decision-making. The mechanism is straightforward: light signals reaching the retina early in the day set the biological clock that regulates energy, alertness, and mood across the full 24-hour cycle. Get it wrong and you spend the day slightly out of phase — foggy, flat, running on fumes. Ten to fifteen minutes of direct morning sunlight is enough to make a meaningful difference. It costs nothing.

Get it wrong and you spend the day slightly out of phase — foggy, flat, running on fumes. Ten to fifteen minutes of direct morning sunlight is enough to make a meaningful difference. It costs nothing.

6. Body-Weight Control
Excess body fat has been linked to lower metabolic efficiency, higher systemic inflammation, and increased energy fluctuations — all of which translate directly into reduced cognitive performance. Research linking brain insulin sensitivity to adiposity (Kullmann et al., 2020, Nature Communications) gives a clear mechanistic picture: metabolic health and cognitive function are not separate systems. When one is compromised, the other follows. I'm not talking about aesthetics. I'm talking about maintaining the metabolic conditions your brain needs to function at the level your role demands. Body-weight control in this context isn't a fitness goal — it's keeping the hardware in good condition.

Scientific study
A study by Kullmann et al. used neuroimaging to examine the relationship between brain insulin sensitivity and body fat distribution in healthy adults. Higher adiposity — particularly visceral fat — was associated with reduced insulin signalling in brain regions responsible for executive function and self-regulation. The finding matters because brain insulin resistance doesn't just affect metabolism. It directly impacts the cognitive systems you rely on for decision-making and focus. Ref: Kullmann S, et al. Brain insulin sensitivity is linked to adiposity and body fat distribution. Nat Commun. 2020;11:1–10. doi:10.1038/s41467-020-15846-0.

7. Creatine
This one surprised me when I first looked into it. I'd always associated creatine with the gym. But the mechanism that makes it useful there — supporting ATP regeneration during high-demand bursts — also applies to the brain. And once I understood that, it made sense to experiment with it. Your brain runs on ATP. When cognitive demand is sustained and high, ATP availability can become a limiting factor. That's the context in which I started paying attention to the research — specifically the RCT review by Avgerinos et al. (2018, Experimental Gerontology), which looks at creatine supplementation and cognitive function and suggests it may support brain energy availability under exactly these conditions. I'm not going to tell you the effect is dramatic, because for me it isn't. What I can say is that it's become part of my daily stack for the same reason the other five habits are: it's a low-friction, evidence-adjacent thing I can do consistently to keep the system running well under sustained pressure. Whether it makes sense for you is worth looking into with someone who actually knows your full picture.

Scientific study
A systematic review and meta-analysis by Avgerinos et al. examined the effects of creatine supplementation on cognitive function across randomised controlled trials in healthy individuals. The review found that supplementation improved short-term memory and reasoning ability, with effects most pronounced during conditions of metabolic stress or sleep deprivation — precisely the conditions under which cognitive demand is highest. The mechanism proposed: creatine supports the regeneration of ATP in brain tissue, helping maintain energy availability when demand spikes. Ref: Avgerinos KI, et al.

The Bigger Picture
The AI-driven restructuring of the tech industry isn't slowing down. Teams will stay lean. Expectations will keep rising. The people who remain competitive, whether employed or in transition, will be the ones who can maintain high cognitive output over time, not just in short bursts. That requires a systems approach to performance. Not occasional gym sessions and better coffee. Actual infrastructure: sleep, nutrition, movement, stress management, treated with the same rigor you'd apply to any other system that's critical to delivery. Physical debt compounds just like technical debt. Skip the maintenance long enough and you're not just performing worse — you're quietly becoming the ceiling on your own capacity. The seven pillars above aren't about optimizing your way to superhuman performance. They're about keeping the system running well enough to stay in the game, consistently, through a period of real pressure. That's what sustainable high performance actually looks like.
