Physical Recovery Benefits
Muscle Recovery and Inflammation Reduction
Cold water immersion has been shown to effectively reduce delayed onset muscle soreness (DOMS) and accelerate recovery after intense exercise. A 2018 research review of 99 studies suggested that cold water immersion after strenuous exercise may reduce delayed onset muscle soreness, self-perceived feelings of fatigue, and inflammation—but only immersion in water lower than 59°F had a beneficial effect on inflammation1.
A 2023 systematic review found that cold water immersion can effectively reduce muscle soreness and accelerate fatigue recovery when used immediately after exercise2. The researchers recommended athletes immerse in cold water immediately after exercise to experience these benefits.
Performance Enhancement
Cold plunges, as discussed in various sources including Chill Soak, may help maintain athletic performance between training sessions. A 2022 research review of 52 studies suggests that cold water immersion following high-intensity exercise has positive outcomes for muscular power, perceived recovery, and reduced muscle soreness 24 hours later. This is particularly beneficial for athletes competing in back-to-back races or same-day training sessions.
A 2014 study found that engaging in 10 minutes of cold water immersion at 50°F following high-intensity resistance exercise "enhanced recovery of submaximal muscle function." Participants in the cold water group were able to lift more weight in muscle function tests compared to those who had engaged in active recovery methods.
Physiological Mechanisms
Cold water immersion works by triggering several physiological responses:
- Vasoconstriction (narrowing of blood vessels)
- Decreased metabolic activity
- Alterations in hormone production and blood flow
- Activation of the immune system11
These responses help reduce exercise-induced muscle damage, which leads to less inflammation and faster recovery of physical performance.
Mental Health Benefits
Mood Enhancement
Research indicates cold plunging results in significant mood improvements. A 2021 study found that students who engaged in cold water immersion experienced a significant decrease in negative emotions like tension, anger, depression, fatigue, and confusion, while experiencing boosts in positive emotions such as vigor and self-esteem4.
Another study involving thirty-three adults new to cold-water swimming highlighted similar benefits. After immersing in a cold bath for just five minutes, participants reported feeling more active, alert, attentive, proud, and inspired4.
For those interested in trying out cold water immersion for its mental health benefits, the ColdCore Inflatable Ice Bath Tub could be an excellent investment. This inflatable ice bath tub offers durability, health benefits, and an easy setup for effective cryotherapy at home.
Stress Reduction
Cold water immersion has been shown to decrease cortisol levels (the primary stress hormone) significantly. According to Dr. David Merrill, psychiatrist and neuroscientist, "The cold shock triggers a surge of norepinephrine, which can boost focus, energy, and stress resilience. It also activates the body's natural recovery processes, reducing inflammation and improving circulation"9.
A recent research review published in PLOS ONE found that while no effects on stress were shown immediately after cold-water exposure, stress levels were improved within 24 to 48 hours afterward9.
Mental Resilience
Regular cold plunging helps train the mind to become comfortable with discomfort, potentially improving overall stress management capabilities. Cold exposure increases the production of norepinephrine, which enhances focus, attention, vigilance, and mood3.
Immune System Support
Cold plunges may strengthen the immune system through several mechanisms:
- Enhanced Circulation: Cold water immersion stimulates blood circulation, helping flush out toxins and bringing oxygen-rich blood to tissues. This is just one of the science-backed benefits of cold plunge therapy.
- White Blood Cell Production: Some studies suggest that cold exposure can increase the count of white blood cells, which are crucial for fighting infections. In fact, research indicates that cold plunges can significantly boost your immune system.
- Reduced Sick Days: A study found that those who regularly take cold showers experienced a 29 percent reduction in sick days from work compared to those who didn't have cold exposure, highlighting another benefit of cold plunges.
- Lymphatic Circulation: Cold water immersion stimulates the lymphatic system, which plays a vital role in immune function. When exposed to cold water, lymphatic vessels contract and force the lymph fluid through the lymph nodes more effectively.
For those looking to explore this therapeutic approach further, cold plunge tubs are a great option. They provide an optimal recovery experience and can be used conveniently indoor or outdoor.
Comparing Recovery Methods
Cold Plunge vs. Hot Tub
Feature | Cold Plunge | Hot Tub |
Temperature | 39-59°F (4-15°C) | 100-104°F (38-40°C) |
Primary Effect | Vasoconstriction | Vasodilation |
Recovery Focus | Reduces inflammation, muscle soreness | Relaxes tight muscles, alleviates pain |
Best For | Post-workout recovery, inflammation reduction | Muscle relaxation, stress relief |
Session Length | 5-15 minutes | 15-30 minutes |
Mental Effect | Alertness, focus | Relaxation, stress reduction |
Both methods improve blood circulation and aid muscle recovery but through different mechanisms. Cold plunges reduce inflammation through vasoconstriction, while hot tubs relax muscles through vasodilation.
For those considering cold plunge therapy, it's worth noting that there are various options available such as the HIEMAL32 cold plunge tub, which is ideal for ice baths at home.

In conclusion, whether you opt for a cold plunge or a hot tub
Contrast Therapy (Hot/Cold)
Contrast therapy—alternating between hot and cold water—combines benefits of both approaches. This method can enhance circulation, reduce muscle soreness, improve recovery times, and provide both relaxation and invigoration.
To perform contrast therapy:
- Start with heat (hot tub or sauna) for 5 minutes
- Switch to cold water for 1-2 minutes
- Repeat the cycle up to five times
For a seamless transition between hot and cold, the Valaris contrast therapy tub from Michael Phelps Chilly GOAT Cold Tubs offers both hot and cold sections in one unit.
When it comes to the cold water portion of the therapy, consider using a cold plunge tub, which is specifically designed for such purposes. These tubs not only offer an immersive cold therapy experience but also come with built-in filtration systems to maintain cleanliness. If you're wondering about the sanitation of these tubs, our guide on whether cold plunge tubs require chlorine explores various sanitation options available.
