Cryotherapy can burn calories by stimulating the body’s metabolism through cold exposure, but the effect is modest and varies per individual.
Understanding Cryotherapy and Its Caloric Impact
Cryotherapy, often referred to as “cryo,” involves exposing the body to extremely cold temperatures for short periods. This method has gained popularity for its potential benefits in recovery, inflammation reduction, and even weight management. But does cryo actually burn calories? The answer lies in how the body reacts to cold stress.
When exposed to cold, the body works harder to maintain its core temperature. This process, known as thermogenesis, requires energy—meaning calories are burned. The main mechanism behind this is shivering thermogenesis and non-shivering thermogenesis. Shivering involves rapid muscle contractions to generate heat, while non-shivering thermogenesis activates brown adipose tissue (BAT), a special type of fat that burns calories to produce heat.
Shivering and Non-Shivering Thermogenesis Explained
Shivering is an involuntary response that can significantly increase calorie expenditure. However, it is uncomfortable and not sustainable for long periods. Non-shivering thermogenesis, on the other hand, is subtler but more efficient. Brown fat cells contain mitochondria rich in iron, which gives them their brown color and unique ability to convert stored fat into heat energy.
Cold exposure triggers the sympathetic nervous system to activate BAT, increasing metabolic rate even without shivering. This means your body burns more calories at rest when exposed to cold environments or cryotherapy sessions.
How Many Calories Does Cryotherapy Burn?
Quantifying calorie burn during cryotherapy can be tricky because it depends on factors such as temperature, duration of exposure, individual metabolism, and body composition. Studies suggest that short whole-body cryotherapy sessions (2-4 minutes at temperatures between -110°C and -140°C) can increase metabolic rate by 10-30% for a short period after exposure.
In practical terms:
- A typical 3-minute session might burn between 50-150 extra calories.
- Longer or repeated exposures may slightly increase total calorie expenditure.
- The afterburn effect (increased metabolism post-session) can last up to an hour or more.
While these numbers sound promising, they are relatively modest compared to traditional exercise methods like running or cycling.
Table: Estimated Calorie Burn Comparison
| Activity | Duration | Approximate Calories Burned |
|---|---|---|
| Whole-body Cryotherapy Session | 3 minutes | 50-150 calories |
| Running (Moderate Pace) | 30 minutes | 250-350 calories |
| Walking (Brisk) | 30 minutes | 120-160 calories |
This table highlights that while cryo burns calories faster per minute than resting at room temperature, it doesn’t match traditional cardio workouts in total calorie expenditure.
The Role of Brown Fat Activation in Calorie Burning
Brown adipose tissue (BAT) plays a pivotal role in how cryotherapy influences metabolism. Unlike white fat that stores energy, brown fat burns energy by producing heat through mitochondrial activity. Adults have small amounts of BAT mostly located around the neck and upper back.
Cold exposure stimulates BAT activity through norepinephrine release from the sympathetic nervous system. This activation increases glucose uptake and fatty acid oxidation in brown fat cells—both processes consume calories.
Interestingly, people with higher amounts of active brown fat tend to have better metabolic health markers such as improved insulin sensitivity and lower body fat percentage. Regular cold exposure could potentially enhance BAT function over time, leading to a higher baseline metabolic rate.
However, BAT activation varies widely among individuals due to genetics, age, gender, and lifestyle factors. Younger people and women typically have more active brown fat compared to older adults or men.
Cryotherapy vs Cold Showers: Which Burns More Calories?
Both cryotherapy and cold showers expose the body to cold stimuli but differ in intensity and duration.
Cryotherapy sessions involve extremely low temperatures (-110°C or lower) but only last a few minutes. Cold showers are longer but usually milder (10–20°C). The intense cold shock from cryo triggers a stronger acute metabolic response but lasts briefly.
Cold showers induce continuous mild shivering and sustained non-shivering thermogenesis over a longer period. This may result in comparable calorie burn if done regularly for several minutes daily.
Ultimately, both methods stimulate calorie burning through similar physiological pathways; however, cryotherapy’s extreme cold offers a more concentrated burst of metabolic activity.
The Science Behind Cryo’s Afterburn Effect
The afterburn effect—officially called excess post-exercise oxygen consumption (EPOC)—refers to elevated metabolism following physical activity or other stressors like cold exposure.
During cryotherapy:
- The body continues generating heat internally after leaving the chamber.
- Metabolic rate remains elevated as muscles recover from shivering.
- Hormonal responses stimulate lipolysis (fat breakdown) beyond the session’s end.
This means you keep burning extra calories for some time post-cryo—sometimes up to an hour depending on exposure length and intensity. However, this afterburn is still minor compared with EPOC from vigorous exercise sessions lasting 20+ minutes.
Hormonal Effects Linked To Calorie Burning In Cryo Sessions
Cold exposure triggers several hormones involved in metabolism regulation:
- Norepinephrine: Boosts heart rate and activates BAT.
- Cortisol: Released under stress; influences glucose availability.
- Irisin: A myokine released during shivering that promotes browning of white fat.
- Adrenaline: Increases lipolysis for energy supply.
These hormonal shifts contribute collectively toward increased energy expenditure during and after cryotherapy sessions.
Cryotherapy’s Limitations As A Weight Loss Tool
Despite its metabolic benefits, relying solely on cryotherapy for weight loss isn’t realistic or efficient:
- The total calorie burn per session is relatively low.
- It doesn’t replace cardiovascular exercise or strength training benefits.
- Weight loss requires sustained caloric deficit achieved through diet and physical activity.
Cryo serves better as a complementary tool rather than a primary method for burning large amounts of calories or losing significant weight quickly.
Moreover, frequent whole-body cryotherapy sessions can be costly and may not be accessible for everyone. Overhyping its effects risks misleading users about realistic expectations regarding fat loss results.
The Importance Of Combining Cryo With Lifestyle Changes
To maximize benefits:
- Pair cryotherapy with regular exercise: Boost overall calorie burn through aerobic workouts combined with strength training.
- Maintain balanced nutrition: Control caloric intake while supporting muscle recovery.
- Use cryo strategically: Employ sessions post-workout for inflammation reduction alongside slight metabolic boosts.
- Create sustainable habits: Consistency matters more than quick fixes.
Incorporating these elements will ensure that any incremental calorie burn from cryo contributes meaningfully toward broader health goals rather than being isolated efforts with limited impact.
The Safety And Practicality Of Using Cryotherapy For Calorie Burning
Cryotherapy is generally safe when performed correctly under professional supervision. However:
- Avoid prolonged exposure: Sessions typically last no longer than 4 minutes due to frostbite risk.
- Certain medical conditions contraindicate use: Cardiovascular diseases or Raynaud’s syndrome require caution.
- Mild discomfort common: Tingling or numbness during treatment is normal but should not be painful.
Practical considerations also include cost—each session can range from $30-$80—and accessibility since specialized equipment is required.
For those unable or unwilling to try whole-body cryotherapy chambers, localized cryo treatments targeting specific areas offer limited systemic calorie-burning effects but may assist with pain relief or skin tightening instead.

Does Shivering During Cryo Burn More Calories?
Shivering thermogenesis significantly increases calorie burn as muscles contract rapidly to produce heat. However, it is uncomfortable and not sustainable for long periods during cryotherapy sessions.
Can Non-Shivering Thermogenesis in Cryo Help With Weight Management?
Non-shivering thermogenesis activates brown adipose tissue (BAT), which burns calories efficiently without muscle contractions. This subtle process can increase metabolic rate and contribute to calorie burn during and after cryotherapy.
How Long Does the Calorie-Burning Effect of Cryo Last?
The afterburn effect from cryotherapy can last up to an hour or more post-session. During this time, the body’s metabolism remains elevated, continuing to burn extra calories even after leaving the cold environment.
The Bottom Line – Does Cryo Burn Calories?
Yes—cryotherapy does burn calories by activating thermogenic processes like shivering and brown fat stimulation during acute cold exposure. It elevates metabolic rate temporarily both during the session and afterward through hormonal responses that promote fat oxidation.
However, the total number of calories burned per session remains modest compared with traditional exercise routines. Cryo should be viewed as an adjunct rather than a standalone weight-loss solution. Its true value lies in recovery support combined with mild metabolic enhancement—not rapid fat melting magic.
Integrating regular physical activity alongside proper nutrition remains essential for sustainable weight management goals. Using cryotherapy strategically can complement these efforts by adding a small yet meaningful boost in calorie expenditure while improving overall wellness markers like inflammation control and muscle recovery.
So yes—does cryo burn calories? Absolutely—but don’t expect it alone to torch pounds without putting in some sweat elsewhere!
