Whether you're an athlete seeking optimal performance or an individual looking to rejuvenate your body and mind, the Cryospring Cold-Hot Plunge System offers a refreshing and invigorating experience. Here's what makes it stand out:

Enhanced Athletic Performance and Faster Recovery

Reduce inflammation, lower muscle soreness and improve physical performance.

A meta-analysis of cold-water immersion effects on recovery found that cold exposure can be a highly effective recovery tool after high-intensity exercise or endurance training. Short interval (< 5 mins), cold water immersion demonstrated positive outcomes for muscle power, perceived recovery, and decreased muscle soreness (in part due to a reduction in circulating creatine kinases). 

NOTE: Cold water immersion can limit some of the gains in hypertrophy, strength or endurance if done in the 4 hours or so after training. It’s better to wait 6 to 8 or more hours until after training, or do it before training UNLESS your goal is simply to recover without adaptation (for instance, when in a competition mode and not trying to get better, stronger, etc.) 

Increased Focus and Energy

Own the day.

Deliberate cold exposure causes a significant release of epinephrine (aka adrenaline) and norepinephrine (aka noradrenaline) in the brain and body. These neurochemicals make us feel alert and can make us feel agitated and as if we need to move or vocalize during the cold exposure. Cold causes their levels to stay elevated for some time and their ongoing effect after the exposure is to increase your level of energy and focus, which can be applied to other mental and/or physical activities. 

Greater Stress Resilience

Develop a healthier stress response.

By forcing yourself to embrace the stress of cold exposure as a meaningful self-directed challenge (i.e., stressor), you exert what is called ‘top-down control’ over deeper brain centers that regulate reflexive states. This top-down control process involves your prefrontal cortex – an area of your brain involved in planning and suppressing impulsivity. That ‘top-down’ control is the basis of what people refer to when they talk about “resilience and grit.” Importantly, it is a skill that carries over to situations outside of the deliberate cold environment, allowing you to cope better and maintain a calm, clear mind when confronted with real-world stressors. In other words, deliberate cold exposure is great training for the mind.

Improved Mood

Have more awesome days.

While not true of every stress, cold exposure causes the prolonged release of dopamine. Dopamine is a powerful molecule capable of elevating mood, enhancing focus, attention, goal-directed behavior, etc.

Listen to Episode #39 of the Huberman Lab podcast to learn more about dopamine’s role in the body. 

Boosted Metabolism

Burn more calories.

In the short-term, cold exposure increases metabolism as the body has to burn calories to increase core body temperature. The total calories burned from the cold exposure are not that significant. However, the conversion of white fat (energy storage) to beige or brown fat (which are highly metabolically active) can be beneficial for: 

  • Allowing people to feel more comfortable in the cold (i.e., cold adaptation)
  • Triggering further and more sustained increases in metabolism

Of course, calories in (consumed) versus calories out (metabolized) or “CICO” governs whether you gain, lose, or maintain weight. There is no escaping the laws of thermodynamics.

    Cold Exposure FAQs

    How Cold?

    This is the most common question, and it makes sense to ask that. However, it is truly impossible to answer, as some people tolerate cold better than others. The key is to aim for a temperature that evokes the thought, “This is really cold(!), and I want to get out, BUT I can safely stay in.” For some people, that temperature might be 60°F, whereas for others, 45°F.

    Here is the key: the colder the stimulus (water immersion, shower, etc.), the shorter amount of time you need to expose yourself to the cold. One study showed significant and prolonged increases in dopamine when people were in cool (60°F) water for about an hour up to their neck, with their head above water. Other studies describe significant increases in epinephrine from just 20 seconds in very cold water (~40°F). The good news is that as you do deliberate cold exposure more often, you will be more comfortable in the cold at all times and can start to use colder temperatures with more confidence, just like exercise.

    How Long and How Often?

    Consider doing deliberate cold exposure for 11 minutes per week TOTAL. NOT per session, but rather, 2-4 sessions lasting 1-5 mins each distributed across the week. Again, the water temperature should be uncomfortably cold yet safe to stay in for a few minutes. You can do more, but this should be the minimum to achieve the benefits of cold exposure. You can do very cold, very brief exposures for adrenaline release too, but the 11 minutes is based on a recent study by Susanna Søberg that explored a range of effects and is a good solid, basic protocol for ongoing use.

    How Do I Endure the Cold?

    Undoubtedly, during (or before) cold exposure, you will find your mind pushing back against the challenge. Your mind will say, “I really don’t want to do this,” even before getting in, or “Get me out of here.”

    You can imagine those mental barriers as ‘walls.’ Those walls are, in fact, the effects of adrenaline pulses in your brain and body, which in this case is what triggers the eventual adaptive response. After all, if it were easy, then there is no stimulus for your body to change (adapt).

    By maintaining top-down control of your reflexive urge to exit the cold environment, you will have successfully traversed that wall.

    Challenge yourself by counting walls and setting a goal of “walls” to traverse (e.g., 3-5 walls) during the round of cold exposure. You can also go for time. Up to you. The advantage of the walls approach is that it carries over to other scenarios more seamlessly, as most of life’s stressors don’t lend themselves so well to merely timing the duration until it passes. It also enhances your sense of mind-body connection to do it this way.

    What Should I Do After a Plunge?

    The Søberg Principle based on deliberate cold researcher Dr. Susanna Søberg is: To enhance the metabolic effects of cold, force your body to reheat on its own. Or “End With Cold.”

    Also, allowing your body to shiver may enhance metabolic increases from cold. Shivering causes the release of succinate from muscles and further activates brown fat thermogenesis. 

    Try this protocol to increase shivering, either during or immediately after cold exposure:

    Don’t huddle or cross your arms while in the cold or after getting out. Also, don’t towel off. Let your body reheat and dry off naturally.

    About Cryospring

    Our Founder's Story

    It was 2021 and I had a great career, a nice home, a loving family, and a group of supportive friends. By all accounts, I had made it. "The good life". Yet there I was, at my lowest. Anxious. Depressed. Feeling hopeless. I was living in my head, and it was a terrible place to be.

    Then, completely by chance, I found it. The cold. A winter plunge into our frigid pool changed me.

    To be honest, I hated it. It hurt. I panicked. I struggled. Why do people do this!? I thought.

    But when I got out, I felt alive. Electric. So I kept at it, and over time, I began to appreciate the cold. I learned to let go. I couldn't beat it. I could only accept it. The cold wasn't something I could control, but I could control how I reacted to it. Just like life.

    I want everyone to experience the life-enhancing benefits of cold water therapy. It isn't just for pro athletes or the "elite". It's for EVERYONE that wants to feel better.
