Don’t Die Podcast #7: How Sauna Improved Bryan Johnson’s Vascular Health
This episode explores how daily 200°F sauna sessions led to major improvements in blood pressure, detoxification, and cellular health in just three weeks.
Today, we explore how 20 minutes a day in a 200°F dry sauna impacted Bryan Johnson’s body and biomarkers.
In Don’t Die Podcast #7, Bryan Johnson shares results from his latest self-experiment: a 21-day high-heat sauna protocol. While most people use a sauna to relax, Johnson’s team treated it like a clinical trial, tracking blood pressure, inflammation, mitochondrial health, and toxin excretion.
The results? Bryan and his team discuss measurable improvements in cardiovascular markers, potential reductions in toxin levels, and elevated heat shock proteins that play a role in cellular repair and longevity. The experience, however, was far from easy and required ice packs on his head and testicles to endure the heat.
Why sauna? The science behind the sweat
Research from Finland and other countries shows sauna use is associated with:
- 50 to 70 percent lower risk of cardiovascular disease
- 40 percent reduction in all-cause mortality
- Reduced dementia and Alzheimer’s risk
Most of these benefits are tied to heat stress, not just sweating. The body responds by increasing nitric oxide, dilating blood vessels, boosting circulation, and mimicking some of the effects of cardiovascular exercise. It also activates heat shock proteins, which repair damaged proteins and reduce inflammation.
Mimicking exercise without moving
Sauna exposure raises heart rate and mimics light aerobic activity like zone one cardio. It’s an “exercise mimetic,” producing cardiovascular effects without physical movement. Bryan saw:
- A 5.8 percent drop in central systolic blood pressure
- A 21 percent improvement in aortic flexibility
- A decrease in arterial stiffness based on augmentation index
These changes came after just 7 sessions and were maintained through 18 to 21 sessions, suggesting sauna is a fast-acting tool for vascular health.
The detox protocol and early biomarker shifts
Bryan and his team tracked 100+ biomarkers including inflammation (CRP), growth hormone, cortisol, vascular age, and mitochondrial function. Highlights included:
- CRP dropped approximately 30 percent
- Blood flow visibly improved during blood draws
- Bryan’s vascular age decreased from 29 to early 20s
Although not all markers changed (his baseline was already elite), the sauna appeared to boost the body’s ability to detox. They expect to see drops in heavy metals, phthalates, and persistent organic pollutants in upcoming urine toxin panels.
Icing testicles, sleepless nights, and cramping
This wasn’t a spa day. For the first two weeks, Bryan felt exhausted, had disrupted sleep, and suffered intense cramps due to electrolyte loss. To mitigate the effects:
- He used ice packs on his head and genitals
- He added 600–700 mg sodium, plus potassium and magnesium, post-sauna
- He wore cotton clothing to avoid plastic toxins
- He shifted his sauna timing away from bedtime to improve sleep
He also avoided pouring water on sauna rocks, due to concerns over toxins in tap water becoming airborne in steam.
Dry vs. wet sauna and how to replicate the protocol at home
Bryan’s team chose a dry Finnish-style sauna at 200°F with 10–20 percent humidity. This style has the strongest research backing. Wet or infrared saunas can still provide benefit, but often don’t reach therapeutic heat levels.
His at-home protocol is:
- 20 minutes at 200°F
- Every day or nearly every day
- Ice packs on sensitive areas
- Electrolyte hydration before and after
- Immediate shower after to wash off toxins
Anyone can start this protocol with modifications. The key is to ease in slowly. Start with 140°F, limit sessions to 2 to 3 per week, and gradually build up.
Who should avoid sauna use?
Bryan’s team flagged several populations who should proceed with caution:
- Pregnant individuals
- People with unmanaged cardiovascular conditions
- Those with electrolyte disorders or dizziness-prone conditions like POTS
Always consult a physician before starting an intense heat therapy protocol.
Sauna and the broader longevity mission
Bryan frames his sauna protocol as more than health optimization. It is part of a broader movement to reduce death in all its forms and extend human potential. The Don’t Die mission is to reject default aging and experiment with new systems of living that improve vitality, brain function, and emotional wellbeing.
Final Thoughts
Bryan Johnson’s sauna protocol isn’t for the faint of heart, but the early results are compelling. From a drop in blood pressure to signs of toxin elimination and increased heat shock protein activity, 20-minute dry sauna sessions may offer one of the simplest, most accessible longevity interventions available today. Whether you’re optimizing for cardiovascular health, brain performance, or detoxification, sauna might be your next great protocol.

Red Mode Is Live: Become a Professional Sleeper
Deep red night screen in one tap, plus Autopilot scheduling that makes it set-and-forget.
Today, I shipped a new iPhone app today called Red Mode.
It’s built for one thing: making it ridiculously easy to get a deep red screen at night, on demand or automatically, without turning your evening into a settings scavenger hunt.

If you’ve been following Bryan Johnson’s longevity work, you’ve probably heard him talk about becoming a professional sleeper. That phrase stuck with me because it’s not about hacks, it’s about building a simple routine you can actually stick to.
Red Mode is my tiny contribution to that idea.
Why I Built It
A lot of people want the benefits of a night friendly screen, but the setup friction is real. iOS can do deep red with Color Filters, and Shortcuts can automate it, but most people never bother because it feels like a hassle.
So I built Red Mode to make the whole thing feel like a product:
- clear setup steps
- one tap actions
- a simple Autopilot schedule
- a clean Wind Down button for nights when you just want it now
The goal is not perfection. The goal is consistency.
What Red Mode Does
Deep Red, One Tap
If you scroll in bed, check your phone in a dark room, or just want a calmer screen at night, this is the main event.
Tap once and your screen goes deep red.
Set It Once with Autopilot
This is the feature I recommend for almost everyone.
Autopilot turns Red Mode on at night and off in the morning. It’s genuinely set-and-forget once you enable it.
Setup is intentionally fast. Installing the included Shortcuts and creating the automations takes about 2 minutes if you follow the steps.
Wind Down Before Bed
Wind Down is for the nights you want an immediate reset.
Use it when:
- you did not set up Autopilot yet
- you are traveling or your schedule is different
- you want a quick, intentional “I’m done for the night” moment
If you do not set up Autopilot, Wind Down is what you will run each night.
If you do set up Autopilot, Wind Down becomes optional, like a manual override.
Morning Red Session
This one is different and very intentional.
Morning Red Session is a bright, timed red screen you can run in the morning. It’s built to support a simple routine with a timer, without overthinking it.
Instant On or Off
You can always toggle red on or off anytime. No ceremony, no digging.
Who It’s For
- bedtime scrollers who want a calmer screen at night
- parents checking a phone in a dark room
- night shift users
- stargazers and anyone protecting dark adaptation
- photographers and darkroom folks who want red light options
- anyone trying to build better sleep habits and a consistent evening routine
Design Notes
I thought a lot about keeping the design quiet and obvious. The app should feel like it belongs on your phone, not like a gadget.
It was a fun project to build, and I hope it’s genuinely useful for anyone who cares about sleep, routines, and longevity.
Price
Red Mode is a $0.99 one-time purchase. No subscription.
Download
You can grab it here:

If you try it, I’d love your feedback. And if you find it useful, a quick App Store review really helps.

The Sleep Blueprint: Bryan Johnson’s Data-Backed Guide to Better Rest
Bryan Johnson shares his personal protocol for mastering sleep, backed by data, wearables, and years of experimentation.
Today, sleep isn’t just rest. It’s a skill you can master. Bryan Johnson calls it the greatest performance enhancing drug on Earth. Not a supplement or a superfood, but something you already do or should do every night.
In his latest video podcast episode, Bryan lays out the advanced sleep system he used to get eight consecutive months of perfect sleep. This isn’t a gimmick or another top 10 list. It’s a personal science experiment, honed by data and habit, that anyone can learn from.
Let’s break down what makes his protocol different and how you can apply it to your life.
Why Sleep Matters More Than You Think
Bryan makes it clear: sleep isn’t just a pillar of health, it’s the foundation. It influences your mood, your memory, your relationships, even your earning potential. And yet, most people treat sleep as optional, sacrificing it for work, social events, or binge watching stressful TV shows.
His point is simple: you wouldn’t show up late to a work meeting, so why show up late to your own bedtime?
Resting Heart Rate is Your Sleep Report Card
The secret weapon of Bryan’s sleep mastery is his resting heart rate before bed. Unlike typical wearables that track heart rate during sleep, Bryan focuses on what it’s doing right before his head hits the pillow.
If your heart rate is low at that moment, you’re primed for a great night. If it’s high, you’re headed for poor recovery. Food, stress, screens, arguments, anything that raises heart rate before bed is the enemy.
He uses this single metric to simplify the chaos of health and behavior. It’s the north star of his evening routine.
Food is the Number One Sleep Killer
According to Bryan and his team, nothing wrecks sleep like eating too close to bedtime, even if the food is “healthy.” Digestion activates the nervous system and raises heart rate. In Bryan’s case, even hummus and vegetables at the wrong time led to poor sleep data.
The takeaway: finish your final meal at least four hours before bed. For best results, aim for six to eight.
Become a Professional Sleeper
One of the most useful mindset shifts Bryan promotes is treating sleep like a job. Schedule it. Protect it. Track it. Improve it.
Here are his 10 essential tips for achieving elite sleep:
- Adopt a professional mindset – Sleep is your job.
- Stop eating early – Final meal 4 to 8 hours before bed.
- Start a wind down routine – 30 to 60 minutes of screen free calm.
- Use light to reset your clock – Get morning light or use a 10,000 lux lamp.
- Stick to a bedtime – Same time every night, ideally within a few minutes.
- Avoid caffeine late in the day – Its half life can destroy sleep quality.
- Eliminate blue light – Use red or amber lighting in the evening.
- Cool your room – 69 to 71°F is optimal.
- Control noise – Use sound machines or earplugs if needed.
- Track your data – Wearables help create powerful sleep habits.
Bonus Tips That Make a Big Difference
The team added a few more actionable strategies:
- Move your phone away from your bed to reduce the temptation to scroll.
- Try journaling before bed to unload mental clutter or anxiety.
- Use your bed only for sleep and sex to train your brain for rest.
- Sleep separately from your partner if necessary and if possible for higher quality rest.
These are the habits that support a long life, strong mind, and healthy body.
Final Thoughts
There’s no magic pill for better sleep. But there is a repeatable protocol, tested by Bryan and fine tuned with real data, that can help you get there. If you’re tired of feeling tired, his approach offers something powerful: control.
Track your heart rate. Experiment with your evening routine. Make one small change today. And most of all, treat sleep with the seriousness it deserves.
If you want to live longer, think sharper, and feel your best, it all starts with sleep. Got a sleep tip that works for you? Share it in the comments below.

Don’t Die Takes Europe: London and Stockholm Host First Global Citizen Meetups
Bryan Johnson connects with Don’t Die followers in London and Stockholm, showing early traction for the movement aiming to reach 1 billion global citizens.

Today, Don’t Die went global as the movement held its first European meetups with in-person events in Stockholm, Sweden over the weekend and London, England earlier this morning. Bryan Johnson made the journey to connect face-to-face with early adopters of his data-driven longevity lifestyle and shared group photos from each location on X. These two gatherings mark a pivotal moment: Don’t Die is beginning to grow beyond its digital roots and build a real-world community.
By rough count, the Stockholm photo shows around 75 people, while the London group (featured above) appears to have about 125 attendees. While modest, these numbers are meaningful. They represent the very first in-person events outside of the United States, indicating the beginning of an international expansion of the Don’t Die Citizenship initiative.
With over 97,860 people following Bryan Johnson on the Don’t Die app, and 12,879 officially registered Don’t Die citizens, the movement is quickly gaining traction. For a mission aiming to reach 1 billion citizens, this growing engagement, now visible across Europe, is a powerful signal that momentum is building. It’s exciting to see the community come alive!
The Data Behind the Movement
When arriving in London, Johnson shared a snapshot of the UK’s health metrics, both strengths and challenges:
- Life Expectancy: The average in the UK is 81 years, well above the global average of 71.
- Infant Mortality: Just 3.8 per 1,000 births, compared to the global average of 27.
- Smoking Rates: Only 12% of UK adults smoke, outperforming the world average of around 20%.
However, the UK also faces serious health issues:
- Obesity: 28% of UK adults are clinically obese, a growing concern that contributes to heart disease, type 2 diabetes, and certain cancers.
- Mental Health: 35% of adults report being in a “distressed” mental state, highlighting a silent epidemic of psychological struggle.
These facts reinforce the need for radical health optimization, which is the core of Johnson’s mission. Don’t Die is not just about living longer, it’s about improving physical and mental performance at the biological level.
A Scientific Take: Why This Matters
While gatherings like these may seem small, they represent a crucial behavior change in health engagement. Science consistently shows that social accountability, group identity, and shared goals significantly improve adherence to health and behavior change programs. For example:
- A 2020 meta-analysis in JAMA Network Open found that social support improves outcomes in behavior-based interventions, including exercise, diet, and stress reduction.
- A 2021 study published in Nature Human Behaviour showed that shared goals in group settings can enhance motivation and resilience.
In other words, these events are more than health meetups. They’re a strategy. Don’t Die is combining quantified self-tracking with real-world social bonds. This is something no other health movement has done at this scale or with this much precision.
Final Thoughts
The Don’t Die gatherings in Stockholm and London are the clearest sign yet that Bryan Johnson’s vision is evolving from a personal protocol into a shared lifestyle. With nearly 13,000 registered citizens and over 97,000 people following Bryan on the Don’t Die app, the movement is picking up global interest and grassroots momentum. As more people join, track their data, and show up in person, Don’t Die is beginning to look less like an experiment and more like a revolution in how we approach health, longevity, and meaning.
