Hello, Efflorescent Friends**! I hope your chilly days of winter have yielded to awakening conversation, warm embraces, and stirring energy. I wrote this next post on a day recognized as Imbolc, the Celtic festival representing the halfway point between Winter Solstice and the Spring Equinox. Imbolc is a time to reflect on transition and letting go, so I humbly offer an opportunity to analyze:
What do you need to let go of that no longer serves you?
What would bring you more balance?
What do you work hard on that DOESN'T serve your dreams?
(Yikes, I feel targeted by this last one! "I should really try taking my own good advice," muses Miss Forever-Spinning-Her-Wheels...)
In this season, I am cultivating balance in part by integrating contrast therapy into my wellness routine. Contrast therapy is a treatment modality where the body is exposed to alternating hot and cold temperatures to trigger rapid response in the body. Let's exploring the potential benefits of this protocol. We'll analyze the effects of a heated environment -- achieved through sauna - and then rapid cooling via cold plunge.
** Efflorescent = someone or something in bloom, flourishing or bursting into flower.
Benefits of Sauna
There's something undeniably magical that happens when you step into a sauna. The heat inches up your arms like an embrace, your Prana comes alive, and beads of sweat bloom across your skin. For a few concentrated moments time slows and all that surrounds you is heat, breath, and heartbeat. This ancient ritual is cathartic and restorative - purging waste while restoring hormonal homeostasis.
For the purpose of setting a baseline, an effective sauna interval exceeds a minimum temperature of 170° F for at least 10 minutes. As you sit in the cloud of heat, your body temperature rises commensurately. In response, your integumentary system produces sweat that excretes from the dedicated glands placed strategically around your body. The moisture brings your body heat down, which, in and of itself, is really incredible, but that's not all! Here's what's going on in your body as you sweat it out:
Detoxification
Sweating is one of the body’s most primal, effective ways to detoxify. The composition of our skin juice (okay, ew, but accurate) is primarily water, but also includes electrolytes (sodium, potassium, and chloride), which facilitate the sweating process, and toxins being evacuated from the body. Most importantly, sweat can help us purge the heavy metals (i.e. lead, zinc, arsenic, mercury) we ingest and absorb from our environment on a daily basis.
Cardiovascular Function
Saunas produce thermal stress, and in response, the cardiovascular system ramps up in an attempt to regulate body temperature. This response involves vasodilation - a widening of the blood vessels - which allows for increased blood flow and lowered blood pressure, to send more oxygen and nutrients to the muscles, organs, and the tissues that hold it all together.
Reduced Inflammation
The thermal stress environment created by exposure to persistent elevated temperatures triggers the body to respond by releasing Heat Shock Proteins (HSPs) and cytokines, both structures comprised of amino acids [[this is a long ass sentence]]. HSPs are present in cells and facilitate protein transfer throughout the body. Additionally, they assist in functionally refolding damaged proteins in cells (holy epic shit). Cytokines are signaling molecules that regulate inflammation and immune responses. Cytokine response includes both pro- AND anti-inflammatory response (separate cytokines for the opposite responses). Sauna use has been shown to increase a type of pro-inflamatory ctyokine (IL-6) temporarily, and then stimulates an anti-inflamatory- triggering cytokine (IL-10). This helps regulate inflammation over time.
Nervous System Regulation
One of the lesser-discussed but deeply felt benefits of sauna use is its effect on the nervous system. The heat encourages parasympathetic dominance—a fancy way of saying it helps your body switch into “rest and digest” mode. You may find that your thoughts slow, your breath deepens, and that subtle internal hum of stress or urgency quiets down. It's like the heat melts away not just physical tension, but mental static, too. Your body, quite literally, learns how to relax in a high-stress environment—and that’s a skill you carry out of the sauna and into your day.
[do we need a few sentence transition here from the benefits to the banter? probably.]
And Then… the Cold
Just when you're fully steeped in the glow and slowness of the sauna, it’s time to pull the ultimate plot twist: the cold plunge. The moment you immerse yourself in cold water, your entire body wakes up. Your breath catches, your mind protests...but if you dare stay—if you breathe—something incredible happens. The cold becomes a teacher. It asks you to be present. It challenges your control. It rewards your courage.
In the next section, I’ll explore what happens physiologically and emotionally in cold plunge, and why this 'yang' to the sauna’s 'yin' might be exactly what your body and spirit are craving this season.
Benefits of Cold Plunge
Cold water is the disruptor, the initiator. Where the sauna lulls you into surrender, the plunge demands you rise. The moment your skin touches the water, your entire system goes on high alert. Your heart races. Your breath shallows. It’s sooo uncomfortable—sometimes even a little terrifying. But here’s the paradox: on the other side of that initial jolt is an immense sense of peace, like you’ve just walked through fire and emerged cleansed by ice.
Let’s dive into what’s really happening when you make that brave decision to step in and stay:
Circulatory + Lymphatic Activation
Cold exposure causes immediate vasoconstriction, narrowing the blood vessels and redirecting blood to your core to protect vital organs. Once you exit the cold, vasodilation follows—flooding fresh, oxygen-rich blood back out to your extremities. This process not only boosts circulation but stimulates the lymphatic system to flush stagnant waste. Think of it as an internal rinse cycle, energizing every system with newfound vitality.
Nervous System Reset
While the cold initially activates the sympathetic nervous system (“fight or flight”), intentional breathing can invite parasympathetic reactivation, essentially rewiring your stress response. You teach your body that it’s safe, even in discomfort. Over time, this strengthens emotional resilience, increases stress tolerance, and enhances mental clarity. It's like biohacking your courage: the more you do it, the more calm you find in chaos.
Mood Elevation
Immersion in cold water triggers a surge of endorphins, dopamine, and norepinephrine—neurochemicals associated with mood and focus. With the rise in dopamine levels, many cold plunge practitioners describe the aftermath of a cold plunge as a full-body high—buzzing, grounded, and fully alive.
Inflammation + Recovery
Cold immersion reduces systemic inflammation and supports muscle recovery by lowering tissue temperature and constricting blood vessels, which minimizes swelling. This makes it an essential practice for athletes, but also for anyone whose body holds the daily weight of modern life—tight shoulders, sore hips, jaw tension from clenching through one too many 'meetings that could have been an email'.
The Ritual of Return
After your plunge, you may notice the world feels crisper, more vivid. Your skin tingles. Your heart softens. There is something sacred in the re-entry—the towel, the tea, the warmth of a blanket, or the way the sun kisses your face with new appreciation. This is where contrast therapy becomes a ceremony: not just hot and cold, but surrender and grit, softness and strength.
The Practice of Contrast
While both sauna and cold plunge offer profound benefits on their own, it’s the intentional alternation between the two that creates a powerful, synergistic effect. This is contrast therapy in its fullest form: exposing the body to extremes in temperature to encourage adaptability, regulation, and renewal.
Moving between hot and cold environments causes your circulatory system, lymphatic system, and nervous system to respond in quick succession—expanding, contracting, flushing, recalibrating. This mimics the natural stress-recovery cycles our bodies evolved with but are often deprived of in modern, climate-controlled life.
In essence, contrast therapy teaches your body to pivot with grace—to feel discomfort without panic, to find stillness in chaos, to recover faster and bounce back stronger.
A common protocol might look like:
10–15 minutes in the sauna
2–3 minutes in a cold plunge
Repeat for 2–3 rounds
End on cold if you want a bracing wake-up, or warm if you're winding down
As all things on your wellness path, let this process be intuitive. Some days you’ll crave the fire more than the ice. Some days the ice will call you home. Let the ritual evolve. Let your body speak.
In the dance between hot and cold, we find a middle place—a pulsing, vital aliveness. Maybe that’s the point: not to choose comfort or challenge, but to let both refine us.
Thanks for reading!
