Sauna in the Summer: Training the Body Through Heat and Breath

It’s 96 degrees outside, and I’m sitting in the sauna.

I’ll admit—I didn’t push the temperature as high as I normally would. In the summer, I tend to keep it around 160 degrees. Still, for most people, the idea of stepping into that kind of heat when it’s already scorching outside feels excessive, if not absurd.

But sauna has never just been about comfort.

The Practice of Voluntary Discomfort

Part of sauna is learning how to sit with intensity. Heat becomes a kind of teacher. At first, it’s overwhelming. Your body resists. Your mind looks for escape.

But over time, something shifts.

You adapt.

What once felt unbearable becomes tolerable, even familiar. And when you step back out into 96-degree air, it no longer feels oppressive—it feels cool, almost refreshing. That contrast isn’t just psychological, though perception plays a role. There’s a real physiological adaptation happening underneath.

How the Body Learns Heat

With repeated exposure, the body becomes more efficient at regulating temperature. Sweating begins earlier and more effective. Circulation improves. The stress response becomes more controlled.

Many people notice this progression clearly:

• Early sessions feel stifling, with minimal sweating and quick fatigue

• Over time, sweat response increases and tolerance improves

• Eventually, the body handles heat with far less strain

  
  

It’s adaptation through exposure. The same principle shows up everywhere in nature.

A tree doesn’t grow strong without wind.

And humans don’t grow resilient without some degree of stress.

Comfort vs. Strength

We live in a world that prioritizes comfort—temperature-controlled environments, constant access to convenience, minimal friction.

But too much comfort has a cost.

Without resistance, systems weaken. Physically, mentally, even emotionally. Sauna becomes one simple, controlled way to reintroduce stress in a way that builds capacity rather than breaks it down.

Breathwork: Expanding the Edge

Lately, I’ve been pairing sauna with another form of controlled stress: breathwork.

Specifically, I’ve been experimenting with Wim Hof breathing—a method that incorporates cycles of deep breathing followed by breath retention. At its core, it’s a form of intermittent hypoxia training, gradually exposing the body to lower oxygen states.

After about seven sessions, I’ve worked up to a breath hold of 2 minutes and 25 seconds.

Like sauna, the process is incremental. You don’t force it—you expand your limits slowly.

This kind of training mirrors high-altitude adaptation. The goal is to improve how efficiently the body uses oxygen, with the broader intention of supporting long-term health, recovery, and resilience.

A Simple Goal

Right now, I’m working toward a 3-minute breath hold by the end of summer.

Not as a performance metric, but as a marker of adaptation—proof that the body, when challenged consistently and intelligently, responds.

Heat. Breath. Stress. Recovery.

These aren’t just practices. They’re reminders that growth doesn’t come from avoiding discomfort—it comes from learning how to move through it.
