Got this a few weeks ago and have been using it four to five times a day. I am a very active and train almost every day. I have used a sauna for years, but the cold plunge has helped eliminate inflation and pain from a shoulder and elbow injury. I am also sleeping better than before plunging and have notice more energy and am starting to look forward to using the plunge. Results exceed my expectation.

Would Recommend

3 Month Update: Been plunging 4 to 5 times a week for the last few months. So far, I haven't experienced any leaks or overall quality issues. I attached two photos of it empty after cleaning it, still in great shape. I add a cup of food-grade hydrogen peroxide to the water weekly and performing a thorough cleaning and draining once a month. I'm 6' and 215 pounds, I find I can comfortably sit cross-legged with the water level reaching my neck. Been freezing water in Tupperware for ice and find doing it in the morning requires less time and ice to cool the water. Based on my experience, I would still recommend this product to others.

Great tub

Have had no issues with it, I use it every other day. Its not that hard to get the water in the low 50s where I like to plunge at. I use a bucket of freezer ice and bunch of ice packs and let it sit for a bit.

Review of Penguin Chiller

Upgraded from a 1/3HP aqua after my pump burned out and its a night and day difference. Easily holds my 100 gallon tub at 45 degrees, is significantly more quite compared to my old one, and seems quite durable. Support at Plunge Junkies was amazing. They answered a lot of questions for me and it arrived within a week of ordering.

Really like the tub, it was pretty quick setup and has a bit more space than I thought. Has a just slight cushiony floor which is very nice.

ZenWave Ice Pod

Quick delivery, for the price its one of the best decisions I've made. I feel so freaking good doing this every morning for 5 minutes.

Was a great Father’s Day surprise and My husband loves it. He is 6.8 he its just bit enough to get his shoulders in. I asked about shipping to make sure it would be here on time and it arrived two days before they say it should take. Thank you!

Love it

Got this ice bath about 3 weeks ago and my BF and I love it! It has a ton of room and was easy to set up. I was scared it won't fit my boyfriend (who is 6f4) and he has lots of room. Even my cool cat seemed interested while we were setting it up lol

We Love Our Sauna

We love our Sauna. It is beautiful!
Delivery went smoothly and it was well packaged and of high quality. We are in our 60's and found it very easy to assemble. We would highly recommend.

Cold Showers and Dopamine

Cold Showers and Dopamine: The Science, Research, & Benefits

Dopamine, commonly referred to as the “feel-good” neurotransmitter, plays an essential role in our sensations of reward, motivation, and pleasure. Surprisingly, cold showers can be a potent stimulant of this neurotransmitter, turning the everyday act of showering into a powerful daily boost.

Cold showers increase dopamine levels in the body by triggering the “fight or flight” response, releasing norepinephrine, which also leads to dopamine release. This can positively impact mood, motivation, focus, and pleasure. Repeated cold exposure may enhance the brain’s dopamine response.

In fact, one study [1] found cold water at 14 degrees Celsius (57 degrees Fahrenheit) increased dopamine by 250%!

In this comprehensive article, we’ll plunge into the intriguing relationship between cold showers and dopamine. We’ll discover how cold showers can act as powerful stimulants and explore the science behind this neurochemical phenomenon, examining the potential benefits of heightened dopamine—including improved memory, creativity, energy levels, and stress reduction.

Additionally, we’ll investigate how cold showers might offer protection against neurodegenerative disorders and their potential role in treating depression and ADHD.

Let’s get to it!

How Do Cold Showers Increase Dopamine?

When you first step into a cold shower, your body goes into a slight state of shock. This is because the cold water is a stressor. To respond to this sudden drop in temperature, your body initiates the “fight or flight” response, which is essentially an evolutionary mechanism to handle immediate threats.

The “fight or flight” response prompts the release of norepinephrine, another neurotransmitter closely related to dopamine. Norepinephrine helps you stay alert and focused and plays a role in the body’s stress response. Interestingly, the pathways in the brain that produce norepinephrine also produce dopamine. So, when cold showers stimulate the release of norepinephrine, dopamine is often released as a byproduct.

Cold exposure, especially through cold showers, activates the brain’s “blue spot,” technically called the locus coeruleus. This area is the primary source of norepinephrine in the brain, and as we’ve mentioned earlier, where there’s norepinephrine, there’s dopamine.

How Do Cold Showers Increase Dopamine

When your body is exposed to cold, it employs a process called thermogenesis to produce heat. There are two types of thermogenesis: shivering and non-shivering. While shivering thermogenesis causes muscles to contract rapidly (you shake or shiver), non-shivering thermogenesis primarily involves the brown adipose tissue (brown fat) generating heat. The process of activating brown fat is regulated by the sympathetic nervous system, which again, taps into the norepinephrine and dopamine-producing pathways.

Cold showers can be both painful (due to the initial shock) and pleasurable (because of the dopamine release). When the body endures a short-term, controlled stressor like a cold shower, it can lead to a phenomenon known as “eustress.” This is a beneficial form of stress that, paradoxically, can make us feel good. The dopamine released in response to the cold shower plays a crucial role in this pleasure sensation.

Just like exercise can “train” the body, repeated cold exposure may enhance the brain’s dopamine response. Over time, with consistent cold showers, your brain becomes more adept at releasing dopamine in response to cold. This doesn’t necessarily mean more dopamine is produced, but rather the sensitivity or response might become more pronounced.

Cold Showers and Dopamine Research

A study titled “Human physiological responses to immersion into water of different temperatures” [1] aimed to understand how different water temperatures affect the hormone and cardiovascular functions of young men. Specifically, it focused on differentiating the effects of cold and hydrostatic pressure (pressure exerted by water due to its weight) on the body. One of the hormones of interest in this study was dopamine.

When participants were immersed in cold water at 14 degrees Celsius (57.2 degrees Fahrenheit), dopamine concentrations in the plasma increased significantly by 250%. This suggests that exposure to cold water triggered a significant release of dopamine in the body, which is a part of the body’s response to cold stress.

Interestingly, when participants were immersed in thermoneutral water at 32 degrees Celsius (89.6 degrees Fahrenheit), dopamine concentrations remained unchanged. This indicates that exposure to water at a comfortable temperature did not elicit the same dopamine response as exposure to cold water.

These findings highlight the link between water temperature and dopamine release in the body during immersion. Cold water immersion seems to stimulate the release of dopamine, while thermoneutral water does not have the same effect on dopamine levels.

How Cold Showers Help Depression

Another study, titled “Adapted Cold Shower as a Potential Treatment for Depression,” explored the hypothesis that depression may be caused by a lifestyle lacking certain physiological stressors that have been experienced by primates through evolution, such as brief changes in body temperature.

Researchers proposed an approach to treating depression using adapted cold showers, with specific parameters: 20 degrees Celsius temperature, 2-3 minutes duration, preceded by a 5-minute gradual adaptation to reduce the shock.

The study found that adapted cold showers increased dopamine levels in the brain. The researchers believe that this is because exposure to cold activates the sympathetic nervous system, which releases noradrenaline. Noradrenaline then binds to receptors in the brain, which increases dopamine production.

It was also found that adapted cold showers reduced symptoms of depression. This suggests that increasing dopamine levels may be an effective way to treat depression.

9 Benefits of Increased Dopamine From Cold Showers

This section explores nine benefits of increased dopamine resulting from cold showers. We’ll discover how cold showers can positively impact mood, motivation, focus, memory, learning, energy levels, stress reduction, creativity, motor control, and even potentially protect against neurodegenerative disorders.

1. Improved Mood, Motivation, and Focus

The increased dopamine and noradrenaline from cold showers could positively impact mood, motivation, focus, and pleasure. Dopamine is involved in reward and motivation, leading to engagement in activities and positive emotions like happiness and excitement.

Similarly, cold showers boost noradrenaline production, aiding mood regulation. This dopamine surge promotes focus, a sense of satisfaction, and a drive to accomplish tasks.

2. Better Memory and Learning

Improved dopamine levels resulting from cold showers have a positive impact on memory and learning processes. There is strong evidence to support that dopamine plays a crucial role in memory formation, retrieval, and working memory functions.[2]

By enhancing dopamine activity, cold showers could potentially strengthen the brain’s ability to encode and recall information effectively.

Furthermore, dopamine’s influence on attention and focus may lead to better concentration during learning tasks. This heightened focus can enhance information retention and comprehension, ultimately improving learning outcomes.

3. Elevated Energy Levels

Cold showers can lead to elevated energy levels through increased release of noradrenaline and improved blood circulation. Noradrenaline, a neurotransmitter and hormone, is known to boost alertness and energy. When exposed to cold water, the body activates its sympathetic nervous system, triggering the release of noradrenaline, providing a natural energy boost.

Additionally, the cold water constricts blood vessels, forcing the heart to pump harder, increasing blood flow to vital organs. This improved circulation delivers more oxygen and nutrients, revitalizing the body and promoting a sense of invigoration.

While the effects may vary from person to person, incorporating cold showers into your routine could potentially help combat fatigue and enhance overall energy levels throughout the day.

Cold Showers Increased Energy

4. Reduced Stress and Anxiety

Cold showers may contribute to reduced stress and anxiety due to their impact on the body’s stress response system. Exposure to cold water stimulates the parasympathetic nervous system, which promotes relaxation and counteracts the fight-or-flight response triggered by stress.

Moreover, cold showers have been shown to lower levels of cortisol, the primary stress hormone. By decreasing cortisol, cold showers can help alleviate feelings of anxiety and tension.

The cold water immersion also activates the body’s endorphin system, leading to the release of feel-good chemicals that can elevate mood and reduce stress.

Incorporating cold showers into your routine, along with other stress-reducing practices, could potentially contribute to a calmer and more balanced state of mind.

5. Enhanced Creativity

Cold showers have the potential to enhance creativity by influencing brain activity and neurotransmitter release. The shock of cold water triggers the body’s stress response, leading to increased alertness and focus. There is evidence that cold water exposure supports interactions between large-scale networks to positively affect brain functioning [3].

Furthermore, cold showers are known to stimulate the release of dopamine, which plays a crucial role in the brain’s reward and pleasure pathways. Dopamine’s involvement in creative thinking and problem-solving suggests that cold showers might facilitate a more innovative and imaginative thought process.

6. Better Motor Control

Improved dopamine levels from cold showers may lead to enhanced motor control and coordination. Dopamine, a neurotransmitter involved in movement regulation, plays a crucial role in fine-tuning motor skills and facilitating smooth movements.

The dopamine surge experienced during and after a cold shower could potentially optimize the brain’s ability to signal motor commands, resulting in more precise and efficient motor control.

Furthermore, dopamine’s influence on motivation and focus could contribute to increased dedication to practice and training, leading to further refinement of motor skills over time.

7. Positive Social Interactions

The increased dopamine from a cold shower could help us to be more open and engaged in social interactions.

When dopamine levels are high, people are more likely to feel motivated and engaged in activities. They may also be more likely to experience positive emotions, such as happiness and excitement.

Positive social interactions can also trigger the release of dopamine. When we interact with others in a positive way, it releases dopamine, which makes us feel good. This can lead to a cycle of positive reinforcement, where we are more likely to seek out social interactions because they make us feel good.

8. Protection Against Neurodegenerative Disorders

The potential link between improved dopamine regulation and cold showers suggests a possible protective effect against neurodegenerative disorders. Dopamine plays a critical role in maintaining brain health, and its dysregulation is associated with various neurological conditions.

By promoting the release of dopamine through cold exposure, cold showers may support the brain’s natural defense mechanisms. Dopamine’s antioxidant properties can help neutralize harmful free radicals, reducing oxidative stress that contributes to neurodegeneration.

Furthermore, dopamine’s influence on mood, motivation, and focus could positively impact cognitive function and delay cognitive decline associated with neurodegenerative disorders.

9. Boosts Testosterone in Men

Cold showers may benefit testosterone levels through their influence on norepinephrine and dopamine. When exposed to cold water, the body responds with a release of norepinephrine and activates the sympathetic nervous system.

This activation indirectly stimulates the hypothalamic-pituitary-gonadal axis, which regulates the production and release of testosterone from the testes.

Additionally, dopamine’s role in reward and motivation might play a part in supporting healthy testosterone levels. As dopamine promotes engagement in activities and positive emotions, it may contribute to overall well-being and hormonal balance, including testosterone synthesis.

Best Cold Showers Temperatures and Time For Dopamine?

Best Cold Showers Temperatures and Time

The ideal temperature and duration for cold showers to stimulate dopamine release can vary from person to person, as individual responses to cold exposure differ. However, based on existing research and common practices, here are some guidelines to consider:

  • Temperature: The water temperature for a cold shower typically ranges between 10 to 15 degrees Celsius (50 to 59 degrees Fahrenheit). This temperature range is cold enough to trigger the body’s stress response and initiate the release of norepinephrine, which is closely related to dopamine release. However, it should be a temperature that you find challenging but manageable.
  • Duration: The duration of a cold shower can vary based on personal preference and tolerance. Generally, a cold shower lasting between 2 to 5 minutes is considered effective. During this time, the body should experience the shock of the cold water, which will activate the sympathetic nervous system and lead to the release of norepinephrine and dopamine.

Remember that the goal of taking cold showers for dopamine release should be a controlled and brief exposure to cold, not prolonged discomfort or extreme cold exposure.

Can You Take a Cold Shower on a Dopamine Detox?

Yes, you can take a cold shower during a dopamine detox.

A dopamine detox is a concept that involves limiting or avoiding activities that provide instant gratification or excessive stimulation in order to reset and regulate dopamine levels in the brain. The goal is to reduce the desensitization to everyday pleasures and to improve focus, motivation, and overall well-being.

Cold showers can be a part of this detox for a couple of reasons:

  1. Building Discipline: Taking a cold shower requires discipline and the ability to resist the immediate comfort of warm water. It can be seen as a challenge to your willpower, which aligns with the idea of reducing instant gratification during a dopamine detox.
  2. Mindfulness and Awareness: Cold showers can be an opportunity to practice mindfulness and be fully present in the moment. The shock of the cold water can bring your focus to the sensations of the body, helping you stay present and mindful.
  3. Boosting Mood and Reducing Stress: Cold showers have been linked to potential benefits for mental health. Exposure to cold water has been found to activate the sympathetic nervous system and increase blood circulation, which may lead to mood improvement and a reduction in stress.

Do Cold Showers Help Depression?

Cold showers have been proposed as a potential intervention for depression[4] due to their ability to stimulate the release of norepinephrine, a neurotransmitter that can elevate mood. When exposed to cold water, the body’s “fight or flight” system is activated, leading to increased alertness and a boost in mood for some individuals.

Additionally, cold exposure activates the brain’s “blue spot” or locus coeruleus, the primary source of norepinephrine. Some research suggests that consistent cold exposure may enhance mood and act as a form of hydrotherapy for depression. However, it’s crucial to note that individual reactions can vary widely.

Cold Showers - Dopamine and Depression

While some people with depression might find cold showers beneficial, others might find them distressing or exacerbating.

As with any self-administered therapy, it’s essential to consult with a healthcare professional to understand the potential benefits and risks in the context of individual health needs.

Do Cold Showers Help ADHD?

Dopamine plays a big role in treating ADHD. Popular ADHD medicines like Ritalin and Adderall boost dopamine in the brain. So, it makes sense to think that cold showers, which can also increase dopamine, might help with ADHD symptoms.

Many people say they feel more alert and focused after a cold shower. This suggests that cold showers could have some of the same benefits as ADHD medications. Of course, the effects of a cold shower might not be as strong or long-lasting as medicine. But the idea of using something simple and drug-free, like cold showers, to help with ADHD is pretty exciting.

In short, cold showers could be a helpful tool for those with ADHD. While more research would be great, trying a cold shower to see if it helps can’t hurt. Plus, cold showers have other benefits too!
