What is a Cold Plunge?

Cold plunging, a cryotherapy, involves immersing your body in cold water. Once your body is in the chilled water or even in an ice bath, your internal temperature drops, your body heat dissipates, and your blood flow changes. Cold plunging proponents believe these changes such as:

• Relieve muscle soreness
• Aid workout recovery
• Reduce inflammation
• Boost immunity

There is even some evidence that it may improve mental health and reduce anxiety.

The Benefits of Cold Plunging

While cold plunging has been around for years, interest in this potential health tool is still relatively new. Still, initial research into its benefits is encouraging. Here is an overview of some of its potential benefits.

Serves as a Workout Recovery Tool

It is expected to experience muscle soreness after an intense workout or athletic competition, mainly if you are a distance runner or engage in HIIT exercises. For this reason, many people turn to cold plunging to aid recovery. 

A review published in the Journal of Sports Medicine found that cold water immersion was an effective recovery tool after high-intensity exercises. Researchers noted that those who used cold water immersion also had lower markers of muscle damage and delayed-onset muscle soreness after high-intensity exercise than people who only used passive recovery.

Relieves Stress and Boosts Mood

Stress and anxiety affect many people. Having another tool to address those feelings and improve overall mood can benefit many people. One study found an association between winter sea swimming or bathing and lower levels of stress and higher overall well-being.

The Psychological Benefits of Cold Water Plunging

Researchers also found that those who engage in cold water plunging also have a heightened understanding of their health and wellness needs. Another team of researchers found that when adults were immersed in water that was 68 degrees Fahrenheit for five minutes, they emerged feeling alert and inspired.

They also had less stress and nervousness. A small study published in Lifestyle Medicine found that a one-time, 20-minute plunge into 56-degree Fahrenheit water helped reduce negative moods.

Reduces Inflammation and Pain

When you plunge into cold water, your blood vessels constrict, reducing blood flow to areas of inflammation. Once you get out of the water, your body naturally pushes blood back to the submerged areas. 

A randomized control study found that cold plunging impacted inflammation and reduced pain in people with gout arthritis, an auto-inflammatory arthritis that generates chronic long-term pain. The cold immersion also impacted their pain perception and improved their joint mobility and quality of life.

Amps up Metabolism

When you are freezing, you tend to shiver, which researchers have found generates extra heat in the body. This shivering may also cause a rise in your metabolic rate, helping you burn more calories at rest. Researchers note that blood also flows to your brown adipose tissue when your body is extremely cold. Also known as brown fat, this tissue helps keep you warm when you are cold and could also help you burn calories.

Regular cold plunging might help you lose weight. It may also help regulate blood sugar and improve insulin sensitivity. However, more research is needed to determine if cold plunging is an effective weight management tool.

Does Cold Plunge Work?

When you plunge into cold water, the cold water immediately removes your body heat, drops your internal temperatures, and changes blood flow. This process has long been thought to treat primary and secondary tissue damage and inflammatory response. It's also why many athletes use ice baths and cold plunges to recover.

But does it work? While evidence is still thin, there is some scientific support that cold plunging may have some beneficial health effects. That said, many of the potential health benefits are based on small studies. For this reason, more evidence-based scientific research documenting the possible health benefits is needed.

What is the Ideal Cold Plunge Water Temp?

Cold is the key term in cold water therapy, not warm, semi-cold, or in-between cold temperatures. The kind of cold used in cold therapy is freezing. The ideal water temperature means you will get maximum benefits from a successful immersion session.

The water's freezing temperature has to be within reason; anything lower than the stipulated temperature range mark is considered extreme. Staying within the correct temperature range is essential not only for the benefits but also for your safety. We cannot emphasize this enough, especially for a beginner.

If you plunge into water without the correct parameters, your body can go into shock, leading to:

• Spike in your heart rate
• High blood pressure
• Hyperventilation

The Search for the Optimal Range for Cold Plunge Water Temp

To jump into freezing water or not to jump? We already know the benefits of cold water therapy, so at this point, we know we will be jumping into the freezing water.

The whole idea of a cold plunge is to challenge your body and activate and trigger specific beneficial actions. The water's temperature range shouldn’t risk your health or push your body beyond its limits.

The temperature has to be in the right range: 

• Not too warm, which defeats the purpose of the cold plunge
• Not too cold, which puts you at risk of some health conditions
  

As a beginner, you should ideally start plunging for shorter durations with water at 60 degrees or near it. Conditioning your body and allowing yourself to adapt slowly will help you get used to the cold temperatures.

Once you become acclimatized, you can gradually move to much cooler temperatures. At this point, you can plunge for a few minutes (2-3). Eventually, you can comfortably plunge at 60 degrees for longer immersions. 

The Optimal Cold Plunge Temperature

A recommended temperature range of 50-60 degrees Fahrenheit is considered optimal for a cold plunge; some individuals can plunge at water that is colder than 50 degrees because the tolerance for individuals varies and is also dependent on one’s experience. Some will be comfortable plunging at temperatures of around 60 degrees F, and others are comfortable with much colder temperatures of 50 degrees F.

Decoding The Temperature Range for Cold Plunge Water Temp

Fifty degrees Fahrenheit is also (10 degrees Celsius) and is considered the lowest temperature point where you can immerse yourself. Going beyond this point can cause harm and adverse reactions.

Sixty degrees Fahrenheit (15 degrees Celsius) is slightly warmer and is an ideal temperature range for beginners getting started on cold water therapy. Opting to go too low than 50 degrees F, believing you can get more benefits, might be dangerous. A temperature higher than 60 degrees F on the hand might not trigger the desired response. 

Studies and Expert Opinions on Ideal Temperatures for Cold Plunging

A journal published in Health Effects of Voluntary Exposure to Cold Water discusses several studies that were carried out to help ascertain the effects of voluntary cold water therapy at different temperature levels. 

Balancing Effectiveness and Safety

We briefly discussed the importance of considering certain factors and steps to ensure safety during a cold plunge. While the correct temperature ensures effectiveness and enhances the desired response, your safety cannot be compromised during and after immersion.

It’s well-known what extended cold exposure can do to you; issues like frostbite and frostbite are the most common. Other medical conditions might also be triggered, which provides good reason to keep your safety and well-being in mind. Some of the other steps to remember are:

• Give your body enough time to acclimatize to cold water gradually
• Pay attention to your body’s signals and avoid pushing it beyond its tolerance level
• Get into a plunge, feet in first, and then slowly immerse yourself. Don’t jump into the plunge
• Stay hydrated

Temperature Effects on Recovery and Wellness 

Cold plunge therapy is only effective at the correct temperature range (50°F- 60°F). If not done within this range, you will not be able to experience its effects and benefits. The proper temperature of the water you’d be immersing yourself in can help recover different areas of your body.

The different temperatures in the indicated range can trigger healing and recovery of various conditions in the body. For instance, a plunge at 10oC (50oF) can accelerate and promote healing after an intense workout. 

Physical Benefits at Different Temperatures for Cold Plunge Water Temp

Most of the benefits of cold water therapy can be immediate or long-term, depending on how you consistently plunge. Some of the benefits of cold plunging at different temperatures are:

• Reduced inflammation and muscle soreness
• Improved blood circulation and flow
• Helps to boost your body’s defense system
• Enhances metabolism, thus helping with weight management
• Boosts your mood by triggering the production of endorphins
• Improves your mental well-being and cognitive performance
• Improves your sleep patterns 

Muscle Recovery and Inflammation Reduction

If you aim to relieve aches and pains from athletic activity or an intense workout through plunging, the ideal temperature range would be between 10 and 14 degrees C. Unlike falling at 20-30 degrees, the above range effectively reduces inflammation, muscle soreness, and recovery.

The action above is possible because your blood vessels constrict, slowing blood flow to the affected area and allowing healing and relief. 

Mental Clarity and Stress Relief

Sometimes, life happens, and with it comes stress, feelings of nervousness, tension, and mood swings. The great thing about cold water therapy is that even a cold bath or shower improves your mood. But if you want to elevate your experience and get more benefits, cold plunging is a great option. 

Optimal Temperature for Mental Clarity

The ideal immersion temperature range to achieve mental clarity and reduce stress is between 50 degrees F – 60 degrees F. A five-minute plunge at these temperatures done even once will elevate your mood, reduce anxiety, and enhance alertness. And, as a plus, you might not have to use medication to help you achieve some of the above benefits of cold plunges. Some drugs require prolonged use to be effective, and they might become addictive; cold plunging is a better alternative.

Specific Cold Plunge Timing Strategies

Focus on duration and frequency. Cold plunge sessions typically last between 2 and 20 minutes, depending on individual goals and cold tolerance. Studies have shown that the colder the stimulus, the shorter the time needed for exposure to the cold. For example, one study found that dopamine levels increased significantly when people were in cool water (60°F) for about an hour with their heads above water. 

Other studies have shown that significant increases in epinephrine can occur after just 20 seconds in very cold water (~40°F). For the most benefits, aim for a temperature where you can stand cold, plunging between 2 and 5 minutes. It's essential to listen to your body and not overdo it. If you start to feel uncomfortable or experience any pain, it's time to get out. 

To aid in recovery and achieve the best results, consider the following guidelines for cold exposure timing:

• Frequency: Ice bath sessions can be performed 2-3 times per week, depending on individual goals and recovery needs. Over time, you may increase frequency based on your cold tolerance and comfort.
• Post-Activity: Cold water immersion within 30 minutes following intense physical activity may yield the most beneficial outcomes, as the body is still in recovery mode. 
• Rest: Adequate rest and recovery between cold plunge sessions are essential to avoid the potential adverse effects of overexposure or cold. Adaptation is key to getting the most out of this therapy.

The ideal temperature for cold exposure varies from person to person, but the key is to aim for a temperature that is cold enough to be uncomfortable but safe to stay in. The colder the stimulus, the shorter the time needed for exposure to the cold. Individuals becoming more accustomed to cold exposure can use colder water more confidently.

Pre-Workout Plunge  

A pre-workout cold plunge can provide various benefits, such as improving alertness, reducing muscle inflammation, and enhancing athletic performance. A randomized controlled study found that a cold water plunge of 10°C before cycling may improve trial time. The timing and temperature of the pre-workout cold plunge are essential factors. 

It is suggested that the pre-workout cold plunge be begun 30-60 minutes before the workout session. This allows enough time for the body to recover and adapt to the changes induced by the cold temperature. The duration of the plunge should be approximately 5-10 minutes.

Post-Workout Plunge

A post-workout cold plunge is widely used to speed up muscle recovery, reduce inflammation, and reduce soreness and joint pain following an intense workout session. This process could also aid in flushing out waste products from the muscles and promoting oxygen and nutrient delivery. Recovery time and plunge temperature are crucial factors in making the post-workout cold plunge efficient. 

The post-workout cold plunge is usually done immediately after completing the workout session. For optimal recovery, a duration of 10-20 minutes is recommended. The temperature of the post-workout cold plunge may vary based on individual preferences. Here's a brief guide to the process: 

1. Prepare the plunge pool or bath with a water temperature of approximately 50°F-55°F (10°C-12.5°C).
2. Submerge the body into the cold water, ideally up to neck level.
3. Remain in the cold water for 10-20 minutes. 
4. Exit the water slowly and let the body dry.
5. Consider additional recovery strategies, like stretching or mild exercises.

Pre-Meeting Plunge

A pre-meeting or morning wake-up cold plunge will boost brain function, catecholamine, and adrenaline. Aim for 35°F- 45°F for 1-3 minutes. The blood vessels constrict, and the nervous system gets a jolt. 

The Effects of Different Cold Plunge Water Temp

The Ice Bath Sweet Spot: 60°F to 70°F

Ice baths at 68°F can significantly boost metabolic health. When exposed to mild cold within this range, the body increases thermogenesis, which means it burns additional calories to generate heat, supporting weight loss and overall metabolic health. 

Research shows mild cold exposure around 68°F to 72°F can enhance energy expenditure without causing significant discomfort. By maintaining indoor temperatures within this range, you can achieve beneficial increases in metabolic rate, promoting better weight management.

Adaptive Cold: 50°F to 60°F Ice Baths

Ice baths within the 50°F to 60°F range can accelerate muscle recovery, which is particularly beneficial for athletes. Studies, such as the one conducted on jiu-jitsu athletes, indicate that cold exposure can decrease muscle damage markers like serum lactate dehydrogenase (LDH) and creatine kinase (CK), reduce perceived muscle soreness, and aid in the recovery of muscle power. 

Optimal benefits are typically observed at temperatures around 6°C (42.8°F). Going colder than this recommended temperature does not appear to provide additional advantages and may even pose risks of cold-related injuries. This range is optimal for post-training recovery, helping you return to peak performance faster.

Extreme Cold: 30°F to 45°F

Ice baths at temperatures between 32°F and 45°F can markedly improve insulin sensitivity. Research shows cold-water immersion at around 39°F can reduce body fat and enhance insulin sensitivity, protecting against cardiovascular diseases and obesity. This temperature range activates brown adipose tissue (BAT), which consumes glucose and lipids, aiding in weight loss and improving metabolic health.

4 Factors to Consider When Choosing a Temperature

1. Individual Cold Tolerance: Know Thyself

Each person’s tolerance to cold water varies, making it crucial to consider individual comfort levels and physical responses when selecting a temperature for cold plunges. Gradually acclimate to more frigid temperatures over time, and be mindful of your body’s reactions to ensure a safe and practical experience.

2. Health Considerations: Proceed with Caution

Before starting cold water therapy, it is essential to consider any pre-existing health conditions. Consult with a healthcare professional to discuss any potential risks or contraindications related to cold water immersion, especially if you have a history of cardiovascular issues or other health concerns.

3. Desired Benefits: What’s Your Goal?

The benefits you hope to achieve through cold water immersion will influence your chosen temperature. For instance, colder temperatures may be more effective in reducing inflammation and muscle soreness, while warmer temperatures may provide a gentler introduction for those new to cold water therapy. Consider the outcomes you want to achieve and adjust the temperature accordingly to maximize the therapeutic effects.

4. Balancing Comfort and Challenge: Find Your Sweet Spot

Finding the right balance between comfort and challenge is key to a successful cold plunge experience. As you become more acclimated to the cold, gradually reduce the temperature to continue reaping the benefits while maintaining a manageable level of discomfort. This approach will help promote adaptation and resilience to cold exposure.

7 Tips for Safe Cold Plunges in Extreme Temperatures

1. Talk to Your Doctor Before Taking the Plunge

Before plunging into cold water, get a checkup from your doctor, especially if you are pregnant or have underlying health conditions, particularly concerning your heart and blood pressure. Cold plunging can stress your heart and cardiovascular system, so it’s best to err on the side of caution.

2. Protect Your Skin From the Cold

Before your cold plunge, get prepared by having warm, dry towels and clothing ready for afterward. Consider wearing a long-sleeved shirt and long shorts to protect your skin from the cold during your plunge.

3. Ease Into the Cold

When you get into an ice bath, don’t just jump in. Start by dipping your toes in, then gradually immerse your feet, followed by your legs, until you’re up to your waist. If you’ve done ice baths before, you can slowly dip your upper body under and even your head.

4. Short and Sweet Sessions

Know your limits. Begin with shorter ice bath sessions, gradually increasing the duration as your body becomes accustomed and your cold tolerance increases. Set an alarm to ensure you don’t stay in your ice tub too long. If you find yourself gasping, excessively shivering, or taking too long to warm up afterward, it’s a sign you should reduce your session length.

5. Mindfulness

Focus on your breath to take your mind off the cold and to help you stay calm. Be conscious of what you can see, hear, and smell.

6. Know the Signs of Hypothermia

Before using an ice bath, be aware of the signs of hypothermia. You could feel weak or lose coordination if your body temperature drops too low.

7. Have a Warm-Up Plan

After your ice bath, create a warm-up routine that raises your body temperature. Have a towel, bathrobe, and dry clothes ready to go. Ask your other half to get a cup of tea ready!

How to Safely Add Cold Plunges to Your Routine

Get Approved by Your Medical Professional

If you have any existing health conditions, especially heart problems, be sure to consult your medical professional before trying cold plunge therapy. Cold water therapy can be shocking to your system, and it is not uncommon for your heart rate and blood pressure to increase suddenly upon immersion. This may pose a risk for individuals with cardiovascular issues.

Start Slow and Take Precautions  

Cold plunges shouldn’t be treated like a game of chicken. Jumping into ice-cold water can be shocking to your system and potentially dangerous. Before you even get into the water, it’s crucial to have a plan. This should include your approach to entering the water, how long you plan to stay, and what you’ll do afterward. You can also take a few minutes to focus on breathing before entering the water to avoid hyperventilating.

Go for a Warm-Up First

If you plan to do cold plunge therapy after exercise, do an active warm-up first. This will help elevate your body temperature and make the transition to cold water easier.

Find Your Optimal Cold Plunge Water Temperature

Cold water can be defined as anything below 70°F. If you're new to cold plunges, you should aim for your water to be between 50 and 60°F, which is typically low enough to elicit benefits.

How Long Should You Cold Plunge?

To trigger the beneficial adaptations mentioned above, you must stay in for at least one minute, ideally two to three minutes, but not more than 10 minutes at a time.

How Often Should You Cold Plunge?

Consider cold plunging a maximum of 1-2 times per week until you notice that your body is acclimating and cold immersion feels less stressful. Finally, more cold plunging is not necessarily better. “You probably don’t need more than 11 minutes per week total of deliberate cold exposure,” says Dr. Maloof. “A lot of people try to go over this and do harm to their health,” she explains. “I had a patient doing long sauna sessions followed by 20-minute cold plunges. He developed major HPA axis dysfunction—a chronic stress condition that exhausts the adrenals and interferes with healthy cortisol output, causing many health issues, including chronic fatigue, depression, and frequent illness.”

How to DIY a Cold Plunge at Home

A DIY cold plunge, or do-it-yourself ice bath, is a therapeutic practice that involves immersing your body in cold water for a short duration. This age-old practice has gained popularity and interest due to its potential health benefits. Creating your cold plunge at home can be a cost-effective way to try cold water therapy and see if it’s something you want to pursue.

How Big Should It Be?

For most people, a container around 5 feet long, 2 feet wide, and 2 feet deep is a good starting point. Taller options are also available for those who prefer to stand or sit more upright in the ice bath, so you should consider this factor. We typically recommend the seated or reclined position because of its:

• Comfort
• Accessibility
• Reduced risk of slipping while in the tub 

Plumbing Considerations for DIY Cold Plunge

Incorporating a reliable drainage system allows for easy emptying and refilling of your plunge and makes cleaning much more manageable. Beyond drainage, recirculation and filtering systems are also worth installing to prevent bacteria from growing in the water and improve temperature consistency.

Can You Convert Your Bathtub into a Cold Plunge?

While you can convert a standard bathtub into an ice bath, other DIY methods are often more popular. A bathtub is typically still used for showering and bathing, meaning that ice must be drained and refilled every time it’s used for cold plunging (which is time-consuming and costly). Bathtubs are also relatively shallow and lack adequate insulation, making body immersion and temperature control challenging. 

Different Approaches

Building DIY cold plunges opens the door to different approaches tailored to:

• Individual preferences
• Budget constraints
• Available space and more

The most popular directions for home ice baths are: 

Chest Freezer

Repurposing a chest freezer is a cost-effective method that often comes to mind because it’s a large container already designed to cool what’s inside. As a result, this approach may require fewer external components. However, you should ensure that it has:

• Proper insulation
• Effective drainage
• Lid sealing to contain the cold
  

Note: Due to safety hazards, we only recommend this method if you have someone else. Forgetting to unplug the freezer before getting in or the lid closing while you are inside are potentially dangerous situations that come with this category of cold plunges. 

Necessary Items

Besides the chest freezer (around $750 - $1,000 for one big enough), this approach will require:

• Installation Tools (hammer, screwdrivers, reciprocating saw, etc.)

Safety Considerations When Cold Plunging

While cold plunges offer numerous benefits, they also pose certain risks, mainly when water temperatures are extremely cold. It’s essential to prioritize safety when engaging in cold water immersion:

Check With Your Doctor First

Cold plunging isn’t for everyone. If you have any underlying health conditions, it’s crucial to consult your healthcare provider before taking the plunge. Cold exposure can affect heart rate and blood pressure, so individuals with cardiovascular issues should avoid cold plunges. Similarly, people with respiratory conditions like asthma may also be at risk, as the shock of cold water can trigger symptoms. It’s best to err on the side of caution and get the green light from your doctor before trying cold plunging. 

Know the Signs of Hypothermia

When engaging in cold-water therapy, monitoring your body’s response and paying attention to warning signs is essential. Prolonged exposure to cold water can lead to hypothermia, which occurs when your body temperature drops to dangerously low levels. 

According to the National Oceanic and Atmospheric Administration (NOAA), the symptoms of hypothermia include:

• Shivering
• Slow, shallow breathing
• Confusion and memory loss
• Drowsiness
• Slurred speech
• Weak pulse
• Loss of coordination
  

If you or anyone else exhibits signs of hypothermia while cold-plunging, getting out of the water immediately and seeking medical attention is crucial.

Understand Your Limits

Cold plunging isn’t a competition. Listening to your body and avoiding pushing yourself too hard is essential. Everyone’s tolerance for cold is different, and your limits can change daily. Factors like your physical fitness, the water temperature, how long you’ve been in the water, and mental state can all affect your response to cold water. If you feel pain or discomfort, it’s time to get out of the water. 

Never Cold Plunge Alone

Always have a partner when engaging in cold-water therapy. If anything goes wrong, they can assist you and call for help if necessary. This is especially important for individuals new to cold plunging or with underlying health conditions. 

Warm Up Before Cold Plunging

Warming up before a cold plunge can help reduce your risk of injury and create a more enjoyable experience. Cold water can shock your muscles and joints, and easing your way into the cold can promote better circulation and reduce the risk of muscle strain. 

Practice Breathwork

Breathwork is another crucial aspect of cold plunging. It involves controlling your breath to enhance your body’s response to the cold temperature. Focusing on deep, slow breaths can help regulate your heart rate and calm any anxiety or discomfort that may arise during the plunge. 

Taking slow, deliberate breaths helps activate the parasympathetic nervous system, which promotes relaxation and counteracts the fight-or-flight response. This allows you to stay present in the moment and fully embrace the refreshing sensation of the cold water surrounding you. So, next time you plunge into icy waters, remember to harness the power of your breath for an even more transformative experience.
