Sweating the Numbers: Exactly How Many Calories Do You Burn in a Sauna?

Sweating the Numbers: Exactly How Many Calories Do You Burn in a Sauna?

Wondering ‘how many calories do you burn in a sauna’? On average, you may burn around 200-500 calories in a 20-minute traditional sauna session, a number that varies based on body weight, muscle mass, and sauna type.


This article unpacks these factors to help you understand what to expect from your sauna experience in terms of calorie expenditure.

Key Takeaways


  • Saunas increase heart rate and sweating, which leads to a minor calorie burn; however, they are not a significant contributor to fat loss when compared to exercise.
  • Various factors affect calorie burn in a sauna, including the type of sauna (with infrared saunas potentially offering a higher calorie burn), session duration, body weight, muscle mass, and individual health conditions.
  • While saunas can aid in weight loss predominantly by increasing metabolic rates and enhancing exercise performance, actual fat loss is minimal, and most weight lost during sauna sessions is water weight, which is regained upon rehydration.

Saunas are more than just a relaxing experience. They are a hotbed for calorie burn! When you sit in a sauna, your heart rate increases, your blood vessels dilate, and your body works up a sweat - all of which require energy.


This energy is drawn from your body’s calorie reserves, thus leading to a sauna burn. In fact, saunas burn calories effectively, making them a popular choice for those looking to shed some pounds.


But how exactly do these factors contribute to calorie burn? Let’s break it down.

The Science Behind Heat and Calorie Expenditure

In a sauna, the heat drives up your body temperature, leading to an increased heart rate and triggering the sweating process. It’s akin to your body running a marathon while you’re simply sitting and soaking up the warmth. As your body works to cool down, it burns calories.



But remember, the calorie burn from sitting in a sauna is only slightly higher than resting, indicating that while it contributes to calorie burn, it’s not a significant contributor to fat loss.

Now, let’s talk about infrared saunas. These saunas penetrate the skin more deeply and increase the metabolic rate more than traditional saunas, potentially leading to a greater calorie burn.


For instance, a 30-minute session in a traditional sauna could burn between 300 and 500 calories. But in an infrared sauna, you could burn between 66 to 198 calories in just 10 minutes!


Clearly, when we compare infrared saunas to traditional ones, it’s evident that they offer a higher potential for calorie burn.

Factors That Affect Calorie Burn in a Sauna

The number of calories you burn in a sauna isn’t just about the sauna type or length of the session. It also depends on individual factors like your body weight, muscle mass, and even your health conditions.


People with higher body weight or muscle mass typically burn more calories in a sauna compared to those with less.


Similarly, the duration of your time in the sauna and your individual health conditions also play a role in determining the effectiveness of your sauna session in terms of calorie burn.

Deciphering the Calorie Count

How many calories you burn in a sauna depends on various factors such as the duration of your session, the temperature of the sauna, and your own metabolism. Generally, a 20-minute sauna session can burn around 200-500 calories. 


The answer isn’t straightforward. Estimates for calories burned in a sauna range from 25 to 300 calories for a 30-minute session, depending on various factors.In an average 20-30 minute sauna session, a person can expect to sauna burn calories, with estimates ranging between 130 to 160 calories.


But remember, these are just estimates and the actual number can vary based on factors like your body weight, muscle mass, and individual health conditions.

Estimating the number of calories you burn in a sauna involves a little bit of math. To calculate your burn rate, you need to consider factors like the length of your sauna session, your body weight, and the temperature of the sauna. 


For a more accurate estimate, you can use a sauna calorie calculator that takes into account these variables.

Body Composition and Caloric Output

Your body composition - the amount of muscle versus fat you have - plays an integral role in determining how many calories you burn during a sauna session. 


Typically, individuals with more muscle mass burn more calories in a sauna compared to those with less muscle mass. Even factors like low heat tolerance can affect the number of calories burned.

Real Numbers: Average Calorie Burn Rates

Now that we understand how to estimate calories burned in a sauna, let’s talk about some real numbers. A 30-minute session in a traditional sauna may burn between 46.5 and 62 calories depending on the individual’s basal metabolic rate.


On the other hand, in an infrared sauna, the estimated calorie burn per 30-minute session ranges from 200 to 600 calories. However, remember that these numbers are still estimates and the true caloric burn can often be lower than portrayed.

Weight Loss and Sauna Use

Weight Loss and Sauna Use

Many people turn to saunas with the hope of shedding a few extra pounds. While it’s true that saunas can aid in weight loss by increasing your metabolic rate, they should not be considered a primary source or substitute for calorie reduction necessary for weight loss.


Let’s break down the relationship between weight loss and sauna use.

Can Sauna Sessions Lead to Significant Weight Loss?

The weight loss observed during sauna sessions is often misconceived as fat loss, when it is predominantly due to the loss of water through sweating. As soon as you replenish your fluids, the weight comes back.


However, there are instances where sauna use can lead to some degree of fat loss. For example, overweight or obese individuals may see a more significant loss in body mass, including body fat, during sauna sessions as opposed to those with lower body weights.

Integrating Sauna into Your Weight Loss Plan

The key to achieving sustainable weight loss is to maintain a healthy diet and engage in regular exercise. However, integrating sauna sessions into your plan to lose weight can provide additional benefits.


Regular sauna use can aid weight loss by increasing your metabolic rate by roughly 20%, leading to more calories being burned during and after sessions. 


Plus, sauna sessions can improve your respiratory function and breathing capacity, potentially enhancing your exercise performance and capacity.

Expectations vs. Reality: How Much Weight Can You Lose?

While saunas can complement your weight loss plan, it’s important to have realistic expectations. The weight loss from sauna use is mostly water weight, which is usually regained once the individual rehydrates.


A balanced approach to weight loss includes recognizing that sauna sessions may contribute to calorie burn but should be complemented with a healthy diet and regular physical exercise.

Health Benefits Beyond Calorie Burning

Saunas aren’t just about calorie burning and weight loss. They offer a host of other health benefits that contribute to your overall well-being.


Let’s delve into these benefits.

Cardiovascular Health and Sauna Bathing

Regular sauna use can do wonders for your cardiovascular health. It can lower your blood pressure, improve your circulation, and even reduce your risk of heart-related illnesses.


This is because the heat from the sauna causes your blood vessels to widen, a process known as vasodilation, resulting in improved blood flow.

Saunas and Mental Well-being

Saunas can also boost your mental well-being. Regular sauna use helps reduce the production of cortisol, a hormone linked to increased stress and weight gain.


At the same time, saunas trigger the release of endorphins, the feel-good hormones, helping to alleviate feelings of stress and anxiety.

Sauna Use and Detoxification

Sauna Use and Detoxification

The heat experienced during sauna use can help with the management of pain and fatigue, while also acting as a stress reliever. However, the idea that saunas can detoxify your body by sweating out toxins is largely a myth.


While sweating does help rid the body of certain toxins, the amount and type of substances expelled through sweat are minimal and not enough to significantly impact health.

Sauna Safety and Best Practices

While saunas offer numerous health benefits, it’s important to use them safely. Here are some safety guidelines and best practices to ensure a beneficial and risk-free sauna experience.

Staying Hydrated: The Key to Safe Sauna Use

Dehydration is the greatest risk associated with regular sauna use. That’s why it’s crucial to stay hydrated before, during, and after your sauna session.


Begin hydrating several hours before a sauna session and choose hydrating beverages for rehydration afterwards.

Optimal Sauna Session Length

The length of your sauna session is another important factor to consider. For beginners, start with 5-10 minute sessions and gradually increase over time while avoiding sessions longer than 15 minutes.


Experienced users may stay longer as long as they don’t feel overly warm.

Sauna Calorie Calculator: A Handy Tool

So how can you estimate the number of calories you burn during a sauna session? A sauna calorie calculator can help. 


This tool is designed to estimate the number of calories you burn during a sauna session, taking into account factors like your weight, the duration of each sauna session, and the frequency of sessions.

How to Calculate Calories Burned

Calculating the calories you burn in a sauna is as simple as inputting your weight and session time into the sauna calorie calculator. The calculator uses these variables to give you a personalized estimate of your calorie burn.

Comparing Activities: Sauna vs Exercise

While saunas do burn calories, it’s important to note that they can’t replace exercise when it comes to calorie burning. 


For instance, high intensity interval training or strength training is significantly more effective at burning calories and elevating metabolism than sitting in a sauna.
