Andrew Huberman: My Exact Routine To Optimize Brain & Body, I Do All Of These Every Day!
The Diary of a CEO
· · Hosts: Steven Bartlett · Guests: Andrew Huberman
Summary
Andrew Huberman argues that the biggest gains in health, focus, and longevity come from aligning daily behavior with circadian biology and the stress system rather than trying to suppress cortisol altogether. He frames morning cortisol as useful, not harmful: waking with a sharp cortisol rise supports mood, attention, learning, and lower stress later in the day, while flattened or mistimed cortisol is linked to worse recovery and shorter lifespan. Hydration, early daylight, and exercise are presented as the first levers in that sequence.
A major theme is light exposure. He says sunlight or, if needed, 10,000 lux artificial light in the first hour of the day helps set the clock, while bright nights and evening screens are metabolically and sleep-disruptive. He also argues that long-wavelength light in sunlight may aid metabolism and even vision, especially in people over 40, and that getting light on skin as well as eyes has measurable benefits. Night-shift behavior, in his view, is broader than employment and includes evening device use.
He then moves to exercise, stressing that resistance training and cardio early in the day can improve alertness and learning afterward, while deliberate cold exposure mainly trains composure under adrenaline rather than dramatically raising cortisol. He closes by arguing that stress control is a skill: physiological sighs, long exhales, and deliberate hard things build the brain’s capacity for tenacity and calmer responses under pressure.
Key takeaways
- Huberman says high morning cortisol is beneficial because it improves mood, focus, learning, and the ability to fall asleep later.
- He recommends hydration, bright early light, and exercise as the highest-value low-cost daily protocols.
- He argues that bright nights and evening screens are strongly linked to worse metabolic and sleep outcomes, especially for kids and night-shift-like schedules.
- He says deliberate cold exposure mainly trains adrenal resilience and composure, not a major cortisol spike.
- He claims starches can lower cortisol at night and help some people sleep and feel less stressed.
Notable quotes
“You want this peak in cortisol as high as possible in the first 60 minutes of your day”
“The risk of dying early if you have bright nights goes up immensely”
“Deliberate cold exposure does not raise cortisol. This much. It's amazing to me”
How the episode opens
Here's the diabolical thing. The risk of dying early if you have bright nights goes up immensely. There have been a lot of studies on people after 6 p.m.
on devices getting artificial LED exposure. They live shorter lives. Cancer rates go up.
They're metabolically unhealthy. But here's the really scary thing. We have a generation of kids that are metabolically sick.
They cling to their iPads. They're on devices. But the problem is most things are designed to make people do less of what's good for them.
And we don't talk about this enough. And Andrew, you're one of the most trusted voices in health today. And we've waited many, many years for this protocols, an operating manual for the human body.
These 10 protocols are well established. They're the ones that are going to move the needle the most in terms of one's mental health, physical health, and performance. Okay, so let's get into it.
So protocol number one, you want to get sunlight because exposure each day to the skin, increases testosterone and estrogen in both women and men, and is important for libido. And then the second, and this is really key, is to reduce stress fast. And I'll explain how to do that in a moment.
And then number three, working out with weights for 45 minutes, taking your sets near to failure. It will triple or quadruple your cortisol levels. But a lot of people have been told, don't spike your cortisol.
It's the stress hormone, but it's a preparation hormone. You're preparing for adversity, but also great things. The next thing, and this is one of the most valuable skills.
If you do it for 5 minutes per day, you will experience a significant improvement in mental and physical health. And then sleeping on your side, very important for offsetting dementia, getting rid of bags under your eyes.
