Effectiveness of Cryotherapy for Weight Loss (2025)

Ever wondered if freezing your buns off could help you drop a few pounds? Enter cryotherapy—a trendy treatment where you step into subzero temperatures for a quick chill session. It’s all the rage for its supposed health perks, and one of the buzziest claims?

Weight loss. But is there any real science behind the hype? Let’s dive into the frosty facts and find out if cryotherapy can truly help you slim down.

What is Cryotherapy?

Cryotherapy, also known as cold therapy, is a treatment method that involves exposing the body to extremely low temperatures, typically between -110°C and -140°C (-166°F to -220°F), for a brief duration, usually a few minutes.

This is most commonly done in a cryotherapy chamber that encloses the entire body or through localized devices that target specific areas.

The extreme cold triggers physiological responses in the body, such as:

  • Reducing Inflammation: The cold can decrease swelling and pain by constricting blood vessels and slowing inflammatory processes.

  • Improving Circulation: Once the body warms up after treatment, blood flow increases to nourish tissues and promote healing.

  • Boosting Metabolism: The body works harder to maintain its core temperature during cryotherapy, potentially accelerating calorie burn.

  • Promoting Recovery: Athletes often use cryotherapy to speed up muscle recovery and reduce soreness after intense exercise.

These effects have also led to claims that cryotherapy may support weight loss by increasing the rate at which the body burns calories and potentially aiding fat loss.

However, the effectiveness of cryotherapy for weight loss remains a debated topic and may vary from person to person.

How Cryotherapy Might Promote Weight Loss

Cryotherapy’s potential for weight loss is based on two key physiological mechanisms:

1. Calorie Burn During and After Treatment

  • Thermogenesis:
    • When exposed to extremely low temperatures, the body engages in thermogenesis, a natural process where it works harder to maintain core body temperature.
    • This increased effort raises calorie expenditure during the session and potentially for a short time after.

  • Calorie Estimates:
    • Some studies suggest that a single cryotherapy session can burn 200 to 800 calories, depending on factors such as the individual’s metabolism, the duration of exposure, and the intensity of the cold.

2. Brown Fat Activation

  • What Is Brown Fat?
    • Brown adipose tissue (commonly called brown fat) is a specialized type of fat that burns calories to produce heat. Unlike white fat, which stores energy, brown fat helps regulate body temperature.

  • Cold Exposure Effect:
    • Extreme cold activates brown fat, prompting it to metabolize stored energy to generate heat.
    • This activation contributes to additional calorie burn and may support overall fat loss over time.

While these mechanisms show promise, the overall impact of cryotherapy on weight loss likely depends on other factors, such as individual metabolism, diet, and exercise habits.

Does Cryotherapy Lead to Significant Weight Loss?

While cryotherapy offers certain physiological benefits, its role in achieving significant weight loss is limited and should be considered as part of a broader health and fitness strategy.

Key factors include:

1. Temporary Calorie Burn

  • Short-Term Boost: Cryotherapy can increase calorie expenditure during and shortly after a session due to thermogenesis, but the overall calorie burn is relatively small.

  • Weight Loss Requirements: For sustainable weight loss, a consistent calorie deficit achieved through diet and exercise is essential. A single cryotherapy session alone cannot create the substantial deficit needed for significant weight reduction.

2. Lack of Direct Fat Reduction Evidence

  • Brown Fat Activation: While cryotherapy may activate brown fat and burn additional calories, the impact on total calorie expenditure is modest and unlikely to lead to dramatic fat loss.

  • No Targeted Fat Reduction: There is little scientific evidence supporting the idea that cryotherapy can directly reduce fat deposits or spot-reduce fat in specific areas.

3. Complementary Role in a Healthy Lifestyle

  • Exercise Support: Cryotherapy’s benefits, such as reduced inflammation and improved recovery, can make it easier to maintain a regular exercise routine by minimizing soreness and enhancing performance.

  • Wellness Boost: Its ability to improve circulation and reduce pain may encourage individuals to stay active and consistent with their health goals.

Pros and Cons of Cryotherapy for Weight Loss

Pros

  • Quick and Non-Invasive: Cryotherapy sessions are brief, typically lasting a few minutes, and do not require surgery or recovery time.

  • May Temporarily Boost Metabolism: Exposure to extreme cold can increase calorie burn through thermogenesis, providing a short-term metabolic boost.

  • Reduces Muscle Soreness and Inflammation: Helps alleviate post-exercise soreness and inflammation, making it easier to maintain a regular workout routine.

  • Enhances Recovery and Well-Being: Improves circulation and promotes relaxation, contributing to overall physical and mental recovery.

Cons

  • Limited Evidence of Significant or Long-Term Weight Loss: The calorie burn and fat reduction effects are modest, with no conclusive evidence supporting cryotherapy as a primary weight-loss method.

  • Costly Sessions: Each session can cost $30–$100, making consistent use an expensive commitment.

  • Not Suitable for Everyone: Individuals with certain medical conditions (e.g., cardiovascular issues, cold sensitivity) or pregnant individuals may need to avoid cryotherapy.

  • Temporary Effects: Benefits such as calorie burn and recovery are short-lived and require consistent sessions to sustain any potential advantages.

Who Might Benefit from Cryotherapy?

1. Active Individuals and Athletes

  • Why It’s Beneficial:
    • Helps reduce muscle soreness and inflammation after intense workouts.
    • Enhances recovery, enabling consistent and high-performance training sessions.
    • Alleviates joint pain, making it easier to stay active.

2. Those Seeking Recovery and Pain Relief

  • Why It’s Beneficial:
    • Offers relief for chronic pain conditions like arthritis or muscle stiffness.
    • Aids in post-injury recovery by reducing swelling and promoting circulation.
    • Can be helpful for those recovering from surgeries or physical therapy (with medical approval).

3. Individuals Looking for a Metabolism Boost

  • Why It’s Beneficial:
    • The cold exposure can temporarily increase calorie burn through thermogenesis.
    • May complement broader weight management efforts, such as a calorie deficit and regular exercise.

Conclusion

Cryotherapy offers intriguing potential for boosting metabolism and aiding recovery, but its effectiveness as a weight loss method remains limited.

While it may help burn extra calories and activate brown fat, these effects are insufficient to replace traditional approaches like diet and exercise.

For those interested in trying cryotherapy, it can serve as a supplemental tool to support overall wellness and weight management goals. Always consult a healthcare professional before starting any new treatment.
