Waking up at 5 AM will transform your life. That's the promise. Celebrity culture has made it gospel — Mark Wahlberg, Tim Cook, the Rock — as if the act of rising before dawn is itself the source of their success. This video does something more honest: it tests that claim for 30 days and reports back with uncomfortable nuance.
The verdict? Productivity did improve. Sleep quality landed around 60 percent. Resting heart rate stayed flat at 43 beats per minute — no cardiovascular change whatsoever. And the social life? Strained. The girlfriend? Unhappy. This is a more truthful account than most early-riser evangelism, and I appreciate it for that.
Here's where I want to push back on the framing, though — because the question "does 5 AM matter?" is really a question about circadian biology, and the answer is more sophisticated than any 30-day challenge can reveal.
We have solid research showing that chronotype — your natural tendency toward morning or evening — is largely genetic. Forcing a night owl into a 5 AM schedule doesn't align them with their optimal cortisol curve. It just makes them a sleep-deprived night owl with a 5 AM alarm. The productivity gains some people experience from early rising come not from the hour itself, but from the quiet, the uninterrupted time, the psychological commitment that comes with the ritual.
Compare this to what we see in the Huberman morning routine research in our knowledge base. Huberman's protocol isn't about the clock — it's about anchoring cortisol to light exposure within 30 minutes of waking. The early hour matters only insofar as it gets you outside before artificial light drowns out the natural signal. The biology doesn't care if it's 5 AM or 7 AM. It cares about the sequence: light, movement, no food for a bit, no phone until your nervous system is settled.
There's genuine consensus that consistent sleep and wake times matter enormously for circadian health. Irregular schedules — sleeping until noon on weekends, up at 6 on weekdays — disrupt cortisol rhythms, impair glucose metabolism, and increase inflammatory markers over time. In that sense, the discipline of a fixed wake-up time, whatever that time is, carries real biological value.
But the 5 AM mythology specifically? The evidence doesn't support it as universally superior. What it does support is that mornings, for most people, are protected time — before email, before demands, before the noise of other people's priorities crowds out your own. That's the actual mechanism behind the productivity gains this person experienced. Not the hour. The protection.
If you're considering this challenge, ask yourself one question first: what do you actually want that first hour for? If the answer is "to feel like a high-performer," save yourself the sleep deprivation. If the answer is "to have time to move, think, and set intention before the world interrupts," then yes — anchor that time and protect it. Whether it's 5 AM or 6:30 AM is secondary.
One detail from the transcript I find telling: the participant built micro-tasks into the morning — making the bed, light movement — and those small acts created momentum. That's behavioral activation. Small wins early prime the dopamine (our guide to dopamine) system for larger effort later. That's the real mechanism. Use it at whatever hour your biology allows.
Here's what caught my attention from a different corner of our knowledge base: the cold shower practitioners who wake at 5 AM don't just credit the hour for their clarity — they credit the thermal shock. Cold water first thing in the morning spikes norepinephrine and cortisol in a way that's genuinely alerting, separate from the circadian effect of light. It compresses the grogginess window from 45 minutes to about five. If you're struggling with early rising, pairing it with a cold shower isn't masochism. It's neurochemistry. The two practices together are more powerful than either alone — and that combination is something any morning ritual, at any hour, can incorporate.
