What is a “Cold Plunge?”

A cold plunge, also known as cold water immersion (CWI) or ice bathing, involves submerging the body in cold water, typically at temperatures ranging from 50-60°F (10-15°C).

This practice has gained popularity for its potential health benefits, including improved recovery from physical exertion, enhanced mood, and increased alertness. Cold water immersion can be performed in natural bodies of water, specially designed cold plunge pools, or even at home using a bathtub filled with cold water and ice.

Why is a cold plunge beneficial?

Cold water immersion challenges the body’s organ systems, requiring adjustments to maintain core temperature. This includes mechanisms like peripheral vasoconstriction, where blood vessels in the extremities constrict to preserve core temperature, and metabolic adjustments to generate heat. 

Regular exposure to cold water has been associated with acclimatization effects, such as reduced heat loss and increased resting metabolism in populations habituated to cold water exposure, like the Ama divers of Japan.1

What are the benefits of cold water immersion?

Cold plunging offers numerous health benefits, though the practice isn’t for everyone. The following are the most common and scientifically supported.

  1. Improved Recovery and Reduced Muscle Soreness: Research shows that CWI can significantly reduce muscle soreness after exercise. A systematic review and meta-analysis found that cold water immersion effectively reduces delayed onset muscle soreness (DOMS) after exercise.2 This is believed to be due to the cold’s effect on reducing inflammation and slowing down the metabolic processes associated with muscle damage. However, research also shows that cold water immersion may compromise muscle growth, so strength athletes or those looking to build muscle may be better off utilizing other recovery tools.3
  2. Reduced Inflammation and Enhanced Immune System Function: Cold exposure has been linked to reduced inflammation and improved immune response. A study demonstrated that regular cold water immersions increased white blood cell count and other immune system markers, suggesting an enhanced immune response.4
  3. Improved Mood and Mental Well-being: Engaging in cold water immersion can also have positive effects on mental health. It’s been reported to release endorphins, the body’s natural painkillers, which can lead to improved mood and a sense of well-being. A study highlighted the potential of cold water immersion in treating depression symptoms, showing a significant mood boost among participants.5
  4. Increased Metabolic Rate: Cold exposure through CWI has been suggested to stimulate brown fat activity, which plays a role in thermogenesis and fat burning. This could potentially aid in weight management and improve metabolic health.6

Cold Plunge Time, Temp, and Frequency

The recommended duration and frequency of cold plunges, or cold water immersion (CWI), can vary based on the individual’s goals, tolerance, and physical condition. Scientific studies have investigated various protocols, offering insights into effective practices for recovery, performance enhancement, and health benefits. Here are some guidelines based on scientific literature:


  • Short-duration CWI: Research suggests that even short immersions of around 1 to 5 minutes in cold water (10°C to 15°C) can be beneficial for recovery and the immune system without causing excessive stress.7 Beginners should err on the side of shorter immersions and work up to longer ones.
  • Longer-duration CWI: For acclimation to cold and to get metabolic benefits like increased brown fat activity, durations can extend up to 10-15 minutes. However, these longer durations should be approached with caution and gradually increased as one’s tolerance improves.


  • 10°C to 15°C (50°F to 59°F): This temperature range is commonly recommended for CWI, especially in the context of recovery from physical exertion. Studies have shown that immersing in water within this range can effectively reduce muscle soreness and inflammation post-exercise.8 This temperature range strikes a balance between providing the therapeutic benefits of cold exposure without inducing excessive thermal stress on the body.
  • Below 10°C (50°F): Some research suggests that temperatures lower than 10°C might be used for short durations to enhance mental toughness, increase alertness, and potentially stimulate the production of brown adipose tissue, contributing to improved metabolic activity.9 However, colder temperatures are associated with higher risks, such as hypothermia and cardiovascular strain, especially for individuals not acclimatized to cold exposure.


  • Post-exercise recovery: For athletes or individuals using CWI for recovery purposes, immersions immediately after training or physical activity, ranging from 3 times a week to after every intense training session, have been reported.10 However, as mentioned above, cold plunging may reduce hypertrophy gains, so if you’re interested in building muscle or you’re a strength athlete, CWI may not be the best recovery tool.
  • Health and wellness routines: For general health and wellness, including mental health benefits and immune system enhancement, a frequency of 3-4 times per week is often cited. This allows for adaptation to the cold and the realization of health benefits without overexposure.


  • Individual Variation: It’s important to note that individual responses to CWI can vary widely based on factors like body composition, age, and existing health conditions. What works for one person may not be suitable for another.
  • Gradual Adaptation: If you’re new to cold plunging, the ideal time and temp is to start with shorter, warmer cold plunges. For example, start with one minute at 60° F, then, each week, either increase your time or decrease the temperature.
  • Consultation with Health Professionals: Before starting a CWI regimen, particularly for longer durations or higher frequencies, consulting with a healthcare professional is advisable, especially for individuals with cardiovascular conditions or other health concerns.

In conclusion, while there’s no one-size-fits-all recommendation for the ideal cold plunge time and temp, starting with shorter, more frequent sessions and adjusting based on personal goals and responses appears to be effective. Engaging in CWI as part of a balanced wellness routine, with attention to safety and personal health status, can maximize the benefits while minimizing risks.
