Protocols turns the most useful material from Andrew Huberman's years of neuroscience teaching into routines you can actually follow. Instead of explaining biology for its own sake, each part of the book starts with something you want, such as better sleep, steadier energy or longer focus, and works back to the small daily habits that support it.
I'm still reading it, so these notes will grow. What follows is what has stuck with me so far.
Why an engineer should care
Most of us treat our own body the way bad teams treat production: ignore it until something breaks. Long hours, poor sleep and a screen until midnight feel normal in this industry. Protocols makes a simple case that attention, mood and judgement are biological, and that a few habits move them more than any productivity app.
The foundations come first
The book keeps returning to the same base layer before anything clever:
- Light. Getting outside in morning daylight, and keeping evenings dim, anchors your body clock.
- Sleep. Consistent timing matters as much as duration, and almost everything else gets easier when sleep is right.
- Movement. Regular exercise, including some that's genuinely hard, supports energy and mood, not just fitness.
- Food and caffeine timing. When you eat and when you drink coffee change how alert you feel across the day.
Fix the foundations before you reach for anything clever. Most of the gains are in the boring habits.
Protocols, not rules
What I appreciate is the tone. These are offered as experiments: try one change for a couple of weeks, notice the effect, keep what works. It's the same approach good teams take to process. Change one variable, observe, iterate.
Key ideas
Get morning light.
Daylight early in the day sets your body clock, which shapes alertness, mood and sleep later on.
Protect consistent sleep.
Regular sleep and wake times do more than chasing extra hours on weekends.
Time your caffeine.
Delaying coffee a little after waking, and stopping well before bed, avoids the afternoon crash and protects sleep.
Train focus like a skill.
Attention improves with deliberate practice and recovery, not just willpower.
Treat changes as experiments.
Try one protocol at a time, for long enough to tell whether it works for you.
My take
The maintenance manual most engineers never read.
I'm reading this slowly, one section at a time, and trying the habits as I go, starting with morning light and an earlier cut-off for coffee.
It's not a leadership book, but it belongs on this shelf. The quality of my decisions at work depends far more on how I slept than I'd like to admit.
Who should read it
- Engineers and managers running on too little sleep and too much coffee.
- Anyone who wants practical habits rather than theory.
- Leaders who want to model sustainable pace for their teams.
