Podbit · The Diary Of A CEO with Steven Bartlett
By exhaling fully and holding an empty breath, you can feel your mitochondria consuming the last of your available oxygen in real time. The mounting discomfort — waves, pressure, panic — is the direct sensory experience of electrons losing their destination. Picard calls developing this awareness 'mitoception.'

With Bartlett's Bon Charge face mask as a live prop, Picard explains the cellular mechanism of red light therapy: infrared photons penetrate skin and skull, interact with cytochrome c oxidase in the mitochondrial electron transport chain, and appear to improve energy flow. He cites a compelling recent study where red light on participants' backs during glucose ingestion blunted the blood sugar spike while simultaneously increasing measurable mitochondrial metabolic rate through breath analysis. But Picard immediately introduces a warning: the relationship between light dose and benefit follows the same bell curve as exercise — low to moderate doses trigger healthy adaptive responses; excessive doses create massive reactive oxygen species that overwhelm the cell's defenses and cause apoptosis. Bartlett admits to occasionally using the device for hours at a time, unaware of the risk. The chapter reinforces Picard's broader point that the body is a dynamic equilibrium and that more is almost never better.
Shining red light on the back of participants as they ingested glucose blunted the blood glucose spike, with metabolic measurements suggesting enhanced mitochondrial energy flow was responsible.
Injecting lactate — a signal of high cellular energy resistance — into humans can trigger panic attacks and reawaken traumatic memories in people with PTSD, suggesting anxiety is partly a mitochondrial energy disorder.
Self-help fails because people are sold one universal cure by the hyper-responders who had a transformative result from it. The real problem is context: every method works for the right person at the right time, which is almost never you just because the author says so.
Spencer Greenberg was once so socially anxious his heart pounded just approaching a stranger. His therapist gave him homework: go to a bar alone, talk to 5 strangers. Starting with asking for the time, he worked up to asking men for hugs — and his anxiety fell dramatically in 6 months.
A person who flies regularly but obsessively checks weather forecasts before every flight is not doing exposure therapy — they're teaching their brain that flying is only safe with the ritual. Safety behaviors prevent the brain from ever learning that the feared thing is actually fine.
The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.
In a randomized study of 20 habit techniques, 'habit reflection' stood out: recall a past habit you successfully built, write down what helped you succeed, then apply those same strategies to your new habit. It works because it's self-adapting — it uses whatever worked for YOU.
The tiny habits technique — always having a minimal version of your habit you can do when life gets in the way — keeps the mental machinery of habit formation from breaking. Paradoxically, people given a tiny-habit fallback option were MORE successful at the full habit, not less.
Fears and worries act like playground bullies — they want to ambush you. But when you deliberately seek them out and choose the time of engagement, they lose their power. The volitional act of starting the fight on your own terms is one of CBT's most underappreciated insights.
Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
You rarely control your first reactive thought. But you can train your second thought — the response to the trigger — by asking whether your initial reaction is the most helpful one and replacing it with something equally true but more constructive. Over time, that second thought becomes automatic.
