How to Use a Sauna and Cold Plunge in Denver: A First-Time Guide to Contrast Therapy at The Skin Sanctum
Share
What happens during a session, why people alternate heat and cold, and how to use our private sanctuary room for recovery, stress relief, and nervous system regulation.
If you’ve ever looked at a cold plunge and thought, “Absolutely not,” you’re not alone.
One of the most common things we hear from first-time guests is that they feel intimidated by the idea of cold water, uncertain about how long they should stay in the sauna, or worried they’re somehow going to do the experience incorrectly. Social media often shows athletes plunging into near-freezing water for several minutes while wearing heart rate monitors and talking about discipline, resilience, or performance.
The reality is much simpler.
Contrast therapy, the practice of alternating heat and cold, is not reserved for professional athletes or extreme wellness enthusiasts. It can be adapted to nearly anyone, whether your goal is reducing stress, supporting recovery, improving sleep, or simply carving out an hour where your nervous system gets a chance to slow down.
At The Skin Sanctum, our sanctuary room was designed to feel less like a recovery
studio and more like a private retreat. The room is yours during your session. There is no instructor timing you, no group class, and no expectation that you use either the sauna or plunge a specific way.
Why Denver Residents Are Turning to Contrast Therapy
Living in Denver places unique demands on the body. The elevation, dry climate, active lifestyle, and constant stimulation of city life can leave many people feeling physically and mentally depleted.
Many of our guests arrive because they experience:
- Chronic stress.
- Difficulty relaxing.
- Poor sleep.
- Muscle tension.
- Recovery needs from exercise.
- Anxiety or nervous system overload.
- A desire to disconnect from screens and responsibilities.
Research surrounding both sauna therapy and cold exposure suggests these practices may support circulation, stress resilience, recovery, and nervous system regulation. The benefits appear to come not from the temperatures themselves, but from how the body adapts to them over time.
What Happens When You Enter the Sanctuary
When you arrive, we’ll walk you through the entire room so nothing feels intimidating.
You’ll find towels throughout the space, places to rest, hydration recommendations, and body care products to use after your session. Swimsuits are recommended, although the room remains entirely private during your reservation.
Many guests are surprised to learn that there is no required protocol.
Some people spend their entire session in the infrared sauna. Others use only the cold plunge. Some alternate between both several times. Others meditate, stretch, read, journal, or simply sit quietly between exposures.
The room is designed to support your goals rather than force you into a specific routine.
Beginning With Heat
For most first-time visitors, we recommend starting in the infrared sauna.
Unlike traditional saunas, infrared saunas heat the body directly through infrared wavelengths rather than simply heating the surrounding air. This often allows people to tolerate the experience more comfortably while still increasing core temperature and circulation. Research shows that infrared sauna use raises heart rate, increases blood flow, and stimulates sweating while operating at lower ambient temperatures than traditional saunas.
Most people begin with approximately ten to twenty minutes.
During this time, blood vessels widen through a process called vasodilation. Circulation increases, muscles begin to relax, and many individuals notice their breathing slowing naturally. Some researchers compare the cardiovascular response to moderate exercise because heart rate and circulation both increase substantially during heat exposure.
This is often the moment where people finally realize how tense they have been.
Entering the Cold Plunge
The cold plunge usually feels intimidating until you actually step into it.
Cold exposure creates an immediate response from the nervous system. Breathing becomes rapid, heart rate rises, and the body attempts to protect itself from the temperature change. After several controlled breaths, many people notice this reaction begins to settle.
The goal is not to “win” against the cold.
The goal is to remain calm while experiencing something uncomfortable.
Many first-time guests spend only thirty seconds to one minute in the plunge. Others stay longer as they build tolerance. Research suggests that even short exposures can stimulate norepinephrine release, increase alertness, and support recovery benefits.
The most important skill is breathing.
Slow inhales and extended exhales signal safety to the nervous system and help the body adapt to the cold.
Why Alternating Heat and Cold Feels So Good
One reason contrast therapy has become so popular is that heat and cold create opposite effects within the circulatory system.
Heat causes blood vessels to widen.
Cold causes blood vessels to narrow.
As you alternate between the two, your body repeatedly adjusts blood flow, circulation, and temperature regulation. Researchers often describe this process as a form of vascular exercise because the circulatory system continually adapts to these changing demands.
Many guests describe leaving the room feeling both relaxed and energized at the same time.
A Simple First-Time Protocol for Cold Plunge and Sauna in Denver
For someone visiting the sanctuary for the first time, we often suggest something simple:
Spend 8 to 10 minutes in the infrared sauna.
Rest briefly and hydrate.
Enter the cold plunge for 30 to 90 seconds.
Return to the sauna if desired.
Repeat one or two additional rounds if your body feels good.
Current recommendations for contrast therapy commonly suggest beginning with shorter sessions and gradually increasing tolerance over time rather than pursuing extreme temperatures or long exposures.
The experience should feel challenging, not overwhelming.
Beyond Recovery: The Nervous System Connection
While many people initially come for muscle recovery, they often continue because of how they feel afterward.
Modern life places many individuals into chronic sympathetic activation, commonly called the fight-or-flight state. Constant notifications, stress, work demands, parenting, and responsibilities keep the body activated for long periods.
Contrast therapy creates short, controlled stressors that encourage the body to return to a recovery state afterward. Over time, this may help improve stress resilience and autonomic nervous system flexibility. Researchers describe this process as hormesis, where manageable stress produces beneficial adaptations.
For some people, the greatest benefit isn’t physical recovery. It’s finally feeling relaxed.
Your Session, Your Ritual
The sanctuary room was intentionally designed to remove pressure. You do not need to plunge for five minutes. You do not need to complete multiple rounds. You do not need to be an athlete.
Some guests spend their time stretching. Some meditate. Some sit quietly in the sauna. Others alternate between hot and cold several times.
If you’ve watched our walkthrough video, you’ll see exactly how the room functions, what amenities are available, and how simple the experience truly is. The sanctuary belongs to you during your session, allowing you to move through heat, cold, rest, and recovery however your body needs.
