Does Bryan Johnson Use a Sauna in His Longevity Protocol?

Yes. Bryan Johnson, the entrepreneur behind Blueprint and the “Don’t Die” longevity movement, uses a sauna every single day as a core part of his anti-aging protocol. He sits in a traditional dry sauna at about 200°F for 20 minutes each morning. He does this for the same reasons many others do. Namely, because there’s research linking frequent sauna use to a roughly 40% lower all-cause mortality.

Sauna usage has quietly become one of the most talked-about tools in the longevity world (yes, that exists), and Bryan Johnson is a big reason why. Below, we go into exactly how he uses heat, why he does it, what the science actually shows, and how you can achieve the same benefits at home, all without needing a 200°F room.

What is Bryan Johnson’s exact sauna protocol?

Bryan Johnson uses a traditional dry sauna at 200°F (93°C) for 20 minutes, once a day, in the morning after his workout.

According to his published Blueprint sauna protocol, the humidity stays low (roughly 5–20%). He adds a few signature tweaks: ice packs on his head and testicles to protect his hair and fertility from the heat, Blueprint skincare before and after, and about 36 ounces of mineral-supplemented water when he’s done to rehydrate.

Now, you are probably not a “biohacker,” so you won’t need all of that. The core idea, however, is simple: hot, dry heat, 20 minutes, every day.

Why does Bryan Johnson use a sauna?

He uses heat as a form of “hormesis.” That’s the word for a controlled, beneficial stress that pushes the body to repair itself. His headline mechanism is heat shock proteins.

“When your core body temperature reaches 102.2°F (39°C), your body releases heat shock proteins, which correct damaged and misfolded proteins.” — Bryan Johnson

Beyond heat shock proteins, Johnson credits regular sauna use with improved blood flow, lower inflammation, better metabolic function, and cellular “autophagy” (that’s the word for the process by which the body clears out damaged cells). The through-line through all of this is that a brief, repeated heat stress trains the body to become more resilient. If that sounds familiar, there’s a reason for that: it’s the same logic behind exercise.

What does the science say about sauna use and living longer?

The strongest evidence comes from a 20-year Finnish study: men who used a sauna 4–7 times a week had about 40% lower all-cause mortality and 63% lower risk of sudden cardiac death than men who used it just once a week.

That study, published in JAMA Internal Medicine (Laukkanen et al., 2015), followed 2,315 middle-aged men for a median of 20.7 years. Sudden cardiac death for these men fell from about 10% in once-a-week users to 5% in the 4–7x group, and longer sessions mattered, too.

In fact, sessions over 19 minutes were associated with a larger drop in cardiac risk than sessions under 11 minutes. It’s important to read these as strong associations rather than ironclad proof. After all, the research mostly involved traditional Finnish saunas. However, the “more often, a little longer” process is exactly what Johnson follows.

Bryan Johnson’s dry sauna vs. home infrared sauna

You don’t need a 200°F room to get the same benefits. Here’s how his traditional setup compares with a home infrared sauna.

Can you get Bryan Johnson-style benefits from an infrared sauna?

Yes. The longevity mechanisms Johnson is chasing, raising core body temperature, triggering heat shock proteins, and improving cardiovascular function, don’t require 200°F. They require consistently getting your core temperature up.

Infrared saunas heat the body directly rather than superheating the air, so you reach that core-temperature threshold at a far more comfortable 120–150°F. For most people, that’s the difference between a routine they can actually do every day and one they quietly abandon after a week. It also opens heat therapy up to older adults, beginners, and anyone who finds a traditional sauna overwhelming. If EMF is a concern for a daily-use device, look for independently tested low-EMF units like those in the Health Mate infrared lineup.

How to build your own daily sauna longevity routine

Start conservative and build the habit before you chase intensity.

Aim for 4 or more sessions per week. Frequency is what drove the mortality benefit in the research.

Work up to 19–30 minutes per session, since longer sessions were associated with bigger benefits.

Use a comfortable temperature (115–140°F for infrared); consistency beats extreme heat.

Hydrate before and after, and replace electrolytes if you sweat heavily.

Evening sessions can double as a sleep aid; morning sessions (like Johnson’s) add an energy and circulation boost.

Takeaways

Bryan Johnson uses a traditional dry sauna at ~200°F for 20 minutes, daily.

His stated goal is triggering heat shock proteins and other repair processes through controlled heat stress.

A 20-year Finnish study links frequent sauna use (4–7x/week) with ~40% lower all-cause mortality and 63% lower sudden cardiac death.

You don’t need 200°F. Infrared saunas reach the same core-temperature threshold at 120–150°F, making a daily habit far more sustainable.

Frequency and consistency matter more than extreme heat.

Frequently Asked Questions

Does Bryan Johnson use an infrared sauna or a traditional sauna?

He uses a traditional dry sauna at about 200°F with low humidity. That said, the mechanisms he’s targeting, core-temperature elevation and heat shock proteins, can also be reached with an infrared sauna at a lower, more tolerable temperature.

How hot is Bryan Johnson’s sauna?

Around 200°F (93°C), with relative humidity kept low (roughly 5–20%).

How often and how long does Bryan Johnson use his sauna?

Every day, for 20 minutes, usually in the morning after his workout.

Do you need a 200°F sauna to get the longevity benefits?

No. The research points to core-temperature elevation, frequency, and session length as what matters and not the air temperature itself. Infrared saunas reach that threshold at 120–150°F.

How many times a week should I use a sauna for longevity?

The strongest benefits in the Finnish research appeared at 4–7 sessions per week, with sessions longer than 19 minutes. Even 2–3 times a week showed measurable benefit over once a week.

Is sauna use actually proven to make you live longer?

The evidence is strong but associational. Large observational studies consistently link frequent sauna use with lower mortality and cardiovascular risk, but they can’t prove cause and effect. Treat sauna use as a well-supported complement to exercise, sleep, and diet, not a magic bullet. Check with your doctor if you have a heart condition.

Why does Bryan Johnson put ice on his head and testicles in the sauna?

To shield his hair and his fertility from the heat while still exposing the rest of his body to the beneficial thermal stress. It’s a personal optimization, not a requirement for benefits.
