’ve been talking a lot about the freeze nervous system state as a root cause of digestive issues like slow motility and poor digestion. What’s interesting is that the frozen weather conditions in the Northern Hemisphere often mirror—and even amplify—this internal state.
When it’s cold outside, the body diverts more resources toward keeping vital organs warm. That energy has to come from somewhere, and digestion is often what gets deprioritized. Reduced circulation to the gut, slower enzyme activity, and sluggish motility are common outcomes during colder months, especially for bodies already stuck in survival mode.
There’s a powerful healing tool I’ve used year-round for years, but I find it especially supportive during this time of year: the sauna.
Most people think of sauna as a place to relax or unwind after a workout. But from a healing perspective, sauna does something much deeper. It acts as a hormetic stressor—a gentle, intentional stress that signals the body to adapt, repair, and become more resilient.
Heat sends a clear message to your cells: turn on detoxification, circulation, immune function, and repair.
For people dealing with chronic gut issues, sluggish liver function, stagnant lymph, or a nervous system stuck in survival or freeze, this kind of controlled stress can be profoundly therapeutic. It certainly has been for me, which is why I’m sharing it with you now.
What Heat Turns On Inside the Body
When you sit in a sauna, detoxification comes online almost immediately. Sweat isn’t just water—it carries out heavy metals, environmental toxins, excess hormones, and inflammatory waste products that would otherwise need to be processed by the liver and eliminated through the gut.
For anyone with compromised digestion or bile flow (which is common in people with SIBO), this is significant support. Sauna provides an alternate exit route for toxins, reducing the burden on organs that are already working overtime.
Heat also stimulates the lymphatic system. Unlike blood, lymph doesn’t have a pump; it only moves when we move, breathe deeply, or experience temperature changes. Sauna gently dilates lymph vessels and encourages stagnant fluid to drain, helping clear immune debris and inflammatory byproducts that can leave you feeling puffy, heavy, foggy, or chronically inflamed.
Heat also softens and hydrates fascia, the connective tissue web that surrounds every muscle, nerve, and organ. When fascia becomes tight or dehydrated, circulation is restricted and tension gets trapped in the body. Sauna allows tissues to soften and glide again, which is why it can feel emotionally soothing as well as physically relieving.
Sauna Is Exercise Without Moving
There’s also a cardiovascular effect that surprises people. Sitting in a sauna raises your heart rate and increases blood flow in a way that’s similar to gentle to moderate exercise. Blood vessels learn to dilate, oxygen delivery improves, and the heart becomes more efficient without stressing the joints or muscles.
For people who are too inflamed, exhausted, or dysregulated to exercise, sauna becomes a bridge back to circulation and cardiovascular health. It creates movement even when you are still.
At a cellular level, heat triggers the production of heat shock proteins, which help repair damaged cells, support mitochondrial function, regulate inflammation, and strengthen immune defenses. This is part of why regular sauna use is associated with better metabolic health, improved stress resilience, and long-term neurological and cardiovascular protection.
There is a reason why sauna is so popular in many parts of the world. And I always feel lighter and my body moves easier after a 15 minute session.
Minerals Matter More Than You Think
There’s an important piece that often gets missed. When you sweat, you don’t only lose toxins, you also lose minerals. Sodium, potassium, magnesium, calcium, and trace minerals all leave through sweat, and without replacing them, sauna can start to feel depleting rather than healing.
That’s why I always drink water with electrolytes and trace minerals while I’m in the sauna. It keeps my nervous system and heart steady while detoxification is happening.
Why You Should Take a Binder After Sauna
Sauna mobilizes toxins into circulation. If you don’t bind them, they can be reabsorbed through the gut and sent right back to the liver. Taking a binder afterward helps escort those toxins out so they don’t get recycled.
I think of it as completing the detox loop: heat releases, the binder removes.
An example of a binder is chlorella, activated charcoal or my favorite: Biotoxin Binder made by Cellcore.
Infrared vs. Traditional Sauna
Both types of sauna are powerful, but they feel different in the body. Infrared penetrates more deeply into tissues and tends to be gentler and less hot, which can be good if you’re sensitive, inflamed, or dealing with nervous system dysregulation. I suggest starting with infrared sauna if you are heat intolerant or have trouble sweating.
Traditional saunas are hotter and produce a more intense cardiovascular and sweating response. Some people thrive on that intensity, while others do better with the softer infrared approach.
Who Should Be Careful with Sauna
Sauna is powerful, which means if you have very low blood pressure, severe adrenal or nervous system exhaustion, active infections, are pregnant, or have unstable heart conditions, you should use the sauna with caution or guidance. And your body should feel better afterward, not worse.
How to Use Sauna Safely
If you’re new to sauna, start small. Five minutes is enough to wake up detox and circulation. Gradually work up to fifteen or twenty minutes, then cool off with a rinse or cool air and rest for ten to fifteen minutes.
You can do multiple rounds, but shorter sessions are better than pushing yourself to stay in too long.
One rule matters more than all the others: if you feel dizzy, nauseous, weak, or off then get out. Healing never happens through force or pushing.
Get unstuck with Sauna
At its core, sauna is a way of restoring movement where the body has become stuck. It moves blood, lymph, fascia, and detox pathways even when you’re sitting still.
For bodies that have spent too long inflamed, frozen, or overwhelmed, that internal movement can be the doorway back into flow. 🔥
