Blake Martin got the best news of his life on a Thursday and the worst news less than 24 hours later, while he sat in a parking lot waiting on a pizza. This is a reflection on what his story taught us about holding two big feelings at once, and what that has to do with the practice of sitting in heat, or cold, without flinching, plus an update on what's next for Contrast as we move from pop-up to a permanent home here in San Francisco.

I've spent thousands of hours in the sauna and cold baths. And I've watched what becomes possible when I shift how I relate to these practices.

In the beginning, the cold was unbearable. My entire nervous system was screaming escape... But something changed when I made a different choice.

I still drift back into default mode. I still feel the urge to escape, to fix, to grip. But here's what I discovered: when I decide to practice mindfully, when I actually choose to turn toward the sensation instead of away from it, everything shifts. The intensity doesn't get smaller. The cold is still cold. The heat is still hot. But in that moment of conscious choice, my relationship to the sensation transform.

Most people think of cardio as something you earn through sweat and sore legs. A run, a ride, a class that leaves you breathless. But what if your heart could get a genuine training stimulus while you sit perfectly still?

That's exactly what happens during contrast therapy.

During a recent session, we tracked an average of 122 bpm across three rounds of hot and cold. Peaks hit 183 bpm. No miles. No muscle fatigue. No joint impact.

When you enter a sauna, your body responds identically to vigorous exercise: blood vessels dilate, cardiac output rises, heart rate climbs. The cold plunge reverses it... Three rounds. Three peaks. Cardiovascular interval training driven entirely by temperature

As we closed out 2025, we just wanted to say thank you.

When we started Contrast, we had a clear vision: to create a sanctuary where people can practice an intentional wellness program that cultivates mental clarity, inner connection, and resilience.

Contrast exists because of you. In 2025, we guided 350+ people like you to cultivate presence and helped shape a modality that supports cleansing the mind and body in a noisy world that constantly asks us to do more.

Some of us cannot think our way into calm. When life presses in, the mind starts to spiral. It hunts for safety and resolution, but there is no solid platform for reactive thoughts to land... The way out is through.

We need safe intensity that drops us out of spiraling thoughts and into the body. That shows up in two places that look very different on the surface. In a guided sauna and cold session. In kink spaces where consent and sensation are central. The common thread is practicing presence under pressure, often misread as pain.

Picture this: A packed stadium, bottom of the ninth. Shohei Ohtani eats a 100-mile-per-hour fastball to the shoulder. The crowd roars, teammates surge to the rail, ready to brawl. Ohtani raises one gloved hand, waves them off, and jogs to first. No glare, no trash talk, just a quiet nod that says, 'I'm good.'

That tiny gesture is a masterclass in non-reactivity. In a fraction of a second, a jolt of pain and adrenaline tried to hijack his biology. Ohtani stayed captain of his own ship. He felt the spike but refused to let it write the next chapter.

Most of us start the day with a healthy shot of cortisol. It is the biochemical espresso that lifts the eyelids. Trouble begins when that surge lingers past breakfast, dragging tension, cravings, and fog into the afternoon.

A peer-reviewed study tracked thirty active men through four rounds of dry sauna at 90 degrees Celsius followed by a 1 minute cold plunge. Blood tests taken right before the first heat bout and immediately after the last plunge told a clear story: cortisol fell from 13.6 µg/dL to 9.7 µg/dL. That is roughly a 30 percent drop!

Peace isn’t finding calmer seas; it’s building a better boat.” In last week’s Huberman Lab episode, Andrew Huberman and Ryan Soave break down exactly why our sauna-to-plunge cycles rewire the nervous system—spiking adrenaline, teaching us to “stay put, keep breathing,” and snapping the prefrontal cortex right back online.
