Cold Plunge vs. Contrast Therapy: Which Is Better?
By Michele Brooks, DNP, RN | Balance by Brooks Recovery & Wellness
From professional athletes to recreational runners, people are taking the plunge in hopes of reducing soreness, improving recovery, and feeling better after tough workouts. But what about contrast therapy, which alternates heat and cold exposure? Is one better than the other? Does combining sauna and cold plunge provide additional benefits? And could cold exposure actually interfere with some of the training adaptations you're working so hard to achieve?
The answer depends on your goals.
Recovery is not simply about feeling better after exercise. It's about creating the conditions that allow your body to adapt and perform better over time.
Let's examine what research tells us about cold plunge versus contrast therapy, when each may be useful, and when cold exposure deserves a more cautious approach.
1. What Is Cold Plunge Therapy?
Cold plunge therapy is immersing part or most of the body in cold water for a controlled time period. Research protocols commonly use water temperatures below 59°F (15°C), although temperatures and exposure durations vary considerably. When you enter cold water, your body responds rapidly.
Several physiological changes occur:
Blood vessels near the skin constrict to reduce heat loss.
Heart rate, breathing, and blood pressure may increase sharply during the initial cold shock response.
Skin temperature decreases, and muscle temperature may decrease depending on immersion depth and duration.
Cold exposure can temporarily reduce the sensation of discomfort.
Your body activates thermoregulatory responses to maintain its core temperature.
It is no wonder cold plunging feels different from other recovery methods. However, a strong physiological response does not automatically mean greater recovery benefits.
2. What Is Contrast Therapy?
Contrast therapy involves alternating exposure to warm and cold temperatures. Traditionally, research on contrast water therapy has involved alternating immersion in warm and cold water. At Balance by Brooks Recovery & Wellness, our contrast therapy experience combines infrared sauna and cold plunge. As with all research, we have to be careful when looking at research that is not specifically these methods. We can look at similar research and pose questions but just because a study looked at contrast therapy with warm water and cold water does not atomatically associate those observations with sauna and cold plunge. As would be expected, heat and cold produce different physiological responses. Heat exposure generally increases skin blood flow through vasodilation and promotes sweating. Cold exposure initially causes peripheral vasoconstriction and a cold shock response. Alternating between these environments changes the demands placed on the body's temperature-regulation systems. Contrast therapy is popular among athletes seeking a structured recovery experience, but researchers have not established one universally superior temperature, duration, or sequence. I have noted in other articles that much of the research I have read from major sports science publications have established a temperature of 50-55 degrees F for their studies.
3. Cold Plunge vs. Contrast Therapy: What's the Difference?
Feature | Cold Plunge | Contrast Therapy |
Typical experience | Cold immersion | Infrared sauna followed by cold plunge cycles |
Physiological response | Cooling, vasoconstriction, and cold shock | Alternating heating and cooling responses (vasodilation/heat vs. vasoconstriction/cold) |
Muscle soreness | Evidence supports possible short-term reductions | Some evidence for perceived recovery, with mixed findings |
Athletic performance | Benefits depend on exercise and timing | No consistent evidence of superiority |
Muscle growth | Frequent immediate post-lifting use may interfere by decreasing the adaptation response | Effects of sauna-plus-plunge protocols remain uncertain |
Best consideration | Targeted use when short-term recovery matters | Preference-based recovery with appropriate screening |
Neither approach should be considered automatically better for every person.
4. What Does Research Say About Cold Plunge and Muscle Recovery?
Cold water immersion has been investigated extensively in sports recovery research. A systematic review and meta-analysis involving 52 studies found that cold water immersion improved several recovery outcomes following strenuous exercise, particularly after high-intensity exercise. Reported benefits included improvements in perceived recovery, reductions in delayed-onset muscle soreness, and some improvements in muscular power recovery. However, benefits were not consistent across all outcomes, and improvements in muscular strength were less convincing. A separate review comparing cold water immersion with other recovery methods found that cold immersion performed favorably for some soreness-related outcomes, while performance differences were often small or inconsistent. These findings suggest that cold water immersion can be useful when reducing short-term soreness or preparing for another demanding event is the priority. This does fall in line with popular belielfs that while cold plunge may help with discomfort, it may effect performance through altering the adaptation response that many athletes work toward by participating in a demanding workout. So timing may be key!
What About Contrast Therapy?
Research on contrast therapy is less conclusive. Some studies report improvements in perceived fatigue, while others notice little difference compared with cold water immersion, active recovery, or other interventions. There is currently insufficient evidence to claim that alternating infrared sauna and cold plunge is superior to cold immersion alone. For some people, the combination may simply provide a more enjoyable or relaxing experience. And that preference can matter when developing a sustainable recovery routine.
5. When Cold Exposure May Not Support Your Training Goals
This is one of the most important considerations for athletes.
The goal of reducing soreness immediately after a workout is not always compatible with maximizing the adaptations from that workout.
In other words, exercise creates physiological stress. Your body responds by activating signaling pathways involved in repair, remodeling, and adaptation. Some of those responses are necessary for developing greater strength, muscle mass, and endurance capacity. Cold exposure may influence certain aspects of that process.
A. When Your Primary Goal Is Muscle Growth
If your training goal is to increase muscle mass, cold plunge recovery directly after your resistance workouts may not be your best choice. A 2024 systematic review and meta-analysis found that cold water immersion immediately after resistance training may negate efforts meant to build muscle. Although the available studies had limitations, the findings raise a legitimate concern about using cold immersion after every lifting session.
This is particularly relevant for masters athletes and adults over 50 who are actively working to preserve or increase muscle mass.
Practical recommendation: If building muscle is a major priority, avoid the routine habit of recovery cold plunges directly following your workouts. A better recommendation is to schedule cold exposure on non-lifting days or at a different time, (some experts recommend a time-lapse of at least 3-4 hours) recognizing that research has not established an exact interval that eliminates the potential interference.
B. When You're Trying to Maximize Strength Gains
Research also suggests that repeated cold water immersion immediately after resistance training may reduce some strength adaptations. This does not mean that a single cold plunge will undo your workout. It means that regularly using cold exposure after strength sessions may create a trade-off between short-term comfort and long-term adaptation. For athletes in a progressive strength-building phase, that trade-off deserves consideration.
C. When You're Training for Endurance Adaptations
Endurance athletes often use cold plunges after long runs, races, and demanding training sessions. Cold immersion may reduce soreness and perceived fatigue, particularly when another hard effort is approaching. However, evidence that routine post-exercise cold immersion improves long-term endurance adaptations is limited. For an athlete preparing for a marathon or ultramarathon, recovery decisions should reflect the purpose of the training session.
Ask yourself, is my goal to do this training and have it be a meaningful stimulus which will cause my body to build and adaption to it? If so, then routinely trying to suppress every post-exercise response may not be necessary. If your goal is to recover quickly between closely scheduled races or competitions, then short-term recovery may hold greater value.
D. When You're Working on Tendon or Connective Tissue Adaptation
With a couple tendon/connective tissue injuries this past six months, I dug to really find out where and how do I integrate contrast therapy into my training and rehab shcedule. Tendons and other connective tissues respond to appropriately progressive mechanical loading. Though cold exposure may temporarily reduce discomfort, it is important to know reduced pain does not necessarily indicate that a tendon or other tissue has recovered sufficiently for additional loading. Research has not established that routine cold plunging improves tendon healing or remodeling. For athletes returning from tendon or other musculoskeletal injuries, cold immersion should not replace a progressive rehabilitation program or be used to justify training through worsening symptoms. I, personally, have continued to use contrast therapy on recovery days, approximately 24 hours away from past tendon loading so that I can make the fullest adaptation possible within that time while experiencing the anti-inflammatory benefits from the cold, and the improved circulation from the overall rotation of hot and cold.
E. When You Have Another High-Power Workout Immediately Ahead
Cold exposure can temporarily reduce muscle temperature and affect neuromuscular performance. If you're preparing for sprinting, jumping, heavy lifting, or another explosive workout, entering that session while your muscles remain cooled may work against your immediate performance goals. Allow adequate rewarming before high-power exercise. If you experience stiffness and decreased range of motion in the morning, some athletes find the cold immersion can take away that stiffness and they state they actually move better after therapy.
The Important Takeaway
Cold exposure is a tool, not a requirement.
The right recovery strategy depends on whether your priority is feeling better today, performing again tomorrow, or maximizing adaptation over the coming months.
Those goals are related, but they are not always identical.
6. When Might Cold Plunge Be a Good Choice?
Cold water immersion may be worth considering in several situations.
After a race or unusually demanding workout: When reducing short-term soreness is a priority and the immediate training-adaptation trade-off is less important.
During tournaments or closely spaced competitions: When athletes need to manage fatigue between events with limited recovery time.
During certain high-volume training periods: When soreness or perceived fatigue becomes a practical barrier to completing the next planned session, provided cold exposure fits the athlete's broader training goals.
As a personal wellness experience: Some people enjoy the sensation of cold immersion and choose it as part of their routine.
Outcomes are individual based on any underlying disease processes ie. inflammation, arthritis, autoimmune disorders.
7. When Might Contrast Therapy Be a Good Choice?
Contrast therapy may appeal to people who enjoy both heat and cold exposure.
Potential reasons to choose it include:
A preference for the combination of infrared sauna and cold plunge.
A history of positive performance, pain relief, or improved function with therapy.
An interest in experiencing both heating and cooling sensations.
A scheduled opportunity to step away from daily stress and focus on recovery.
8. Is Cold Plunging Safe for Everyone?
No.
Sudden cold water immersion can trigger a rapid increase in breathing, heart rate, and blood pressure. This cold shock response can be dangerous, especially for people with certain cardiovascular conditions. Cold immersion may also increase the risk of dizziness, loss of coordination, and hypothermia. People with heart disease, arrhythmias, uncontrolled blood pressure, fainting disorders, significant circulation problems, or other relevant medical concerns should obtain appropriate medical guidance before participating. Contrast therapy introduces additional temperature changes and is not automatically safer. Never plunge alone, avoid breath-holding or hyperventilation exercises in the water, keep your head above water, and exit immediately if you experience chest pain, severe dizziness, unusual shortness of breath, or other concerning symptoms.
Longer and colder are not necessarily better.
9. Which Recovery Therapy Should You Choose?
Rather than asking which therapy is best, consider asking:
What am I trying to accomplish with this recovery session?
If your primary goal is reducing soreness after a race, cold water immersion may be worth considering.
If your goal is relaxation and you enjoy alternating temperatures, contrast therapy may be an appealing option.
If you're in a muscle-building phase, routine immediate post-strength-training cold immersion may not be ideal.
And if you're returning from injury, recovery decisions should support—not replace—appropriate rehabilitation and progressive loading.
The best recovery approach should reflect your training schedule, health status, and long-term goals.

Frequently Asked Questions
Is contrast therapy better than a cold plunge?
Not necessarily. Both may offer perceived recovery benefits, but research has not established that contrast therapy is consistently superior to cold water immersion alone.
Should I cold plunge after lifting weights?
If maximizing muscle growth or strength is your primary goal, frequent cold immersion immediately after resistance training may interfere with some adaptations. Consider separating cold exposure from your lifting sessions.
Can cold plunging help after a long run?
Cold water immersion may reduce muscle soreness after strenuous exercise, but the benefits vary. Whether to use it depends on your next training session and overall goals.
Does contrast therapy help with inflammation?
Evidence does not establish that contrast therapy reliably reduces harmful inflammation or accelerates tissue healing. However, heat and cold influence physiological responses associated with circulation and temperature regulation. Cold application is an established measure to decrease inflammation from injury or overuse and improved circulation can bring proper oxygen and nutrients to aid in tissue healing.
How long should I stay in a cold plunge?
There is no universally appropriate duration. Water temperature, individual tolerance, health status, and the intended purpose all matter. Beginners should use conservative exposure under appropriate supervision.
