Why You’re Tired, Stressed & Unfocussed (and how to fix it) - Dr Andrew Huberman
10 protocols for killing fatigue, stress and brain fog. The fix isn't more willpower, it's timing your cortisol, your exhale, and your attention on purpose.
"with things that spike your cortisol at the beginning and lower your cortisol at the end is really it it really is the if there is a cheat code to life" — Dr Andrew Huberman
Dr Andrew Huberman, on the episode
Andrew Huberman sits down with Chris Williamson to unpack the operating system behind his new book, focusing specifically on why so many people feel foggy, wired, and unfocused by mid-afternoon. The pop framing of fatigue and stress is that you need more sleep, more supplements, or more willpower. Huberman's actual model is almost entirely architectural: shape the cortisol curve at the start and end of the day, manage stress through a single breathing mechanism rather than mindset, and treat presence as a trainable perceptual skill rather than a vague state you either have or don't. Across the conversation he keeps returning to the same idea, that small, repeatable, mechanistic interventions beat big, occasional, motivational ones. This protocol pulls the three tactics from that conversation that most directly target tiredness, stress, and brain fog.

Bookend Your Day With Cortisol
The play
Spike cortisol in the first 30-90 minutes with light, hydration, caffeine and exercise, then dim lights and screens in the final hour before bed.
Dr Andrew Huberman says
I set up my morning to spike cortisol and my evening to lower it. I use bright light, hydration, caffeine, and exercise in the first three hours of the day. At night I dim the lights, dim my screen, and limit caffeine to reverse that curve.
Try this
Spike cortisol each morning with light and movement, then dim everything at night.
