Can a Sauna Help You Lose Weight? The Truth Behind the Sweat

Saunas have been used for centuries as a tool for relaxation, detoxification, and overall well-being. But can a sauna actually help you lose weight? If you’ve ever stepped out of a sauna feeling lighter, you’re not imagining things but there’s more to the story than just sweating it out. Let’s break down the science, the benefits, and the limitations of using a sauna for weight loss to learn if saunas can help you lose weight.

Can a Sauna Help You Lose Weight?

The short answer: Yes, but not in the way you might think. We hate to break it to you, but saunas can temporarily reduce body weight by causing water loss through sweating, but they’re not a magic fat-burning solution. The real benefits of saunas for weight management come from their impact on metabolism, circulation, and recovery, all of which can support a healthy lifestyle and have a direct impact on weight loss.

What the Science Says

Don’t just take our word on if saunas can help you lose weight, let’s look at the science. Several studies have explored the effects of saunas on metabolism and calorie burn:

• A study published in the Journal of the American Medical Association found that a 30-minute sauna session can burn approximately 300-600 calories, depending on factors like gender, body weight, heat exposure, and individual metabolism.

• Research in the European Journal of Preventive Cardiology suggests that regular sauna use may improve cardiovascular health and metabolic function, both of which play a role in maintaining a healthy weight.

• A 2019 study in Complementary Therapies in Medicine found that infrared sauna sessions can increase resting energy expenditure (calories burned at rest) due to the heat’s impact on the body’s thermoregulatory processes, which is a fancy way of saying how our body’s maintain a stable body temperature.

How Many Calories Can You Burn in an Infrared Sauna?

Infrared saunas, which heat the body from within rather than just warming the air around you, are particularly effective at increasing heart rate and calorie burn when compared to a traditional sauna.

On average:

• Men can burn between 400-600 calories in a 30-minute infrared sauna session.

• Women can burn between 200-400 calories in the same timeframe.

The exact number varies based on body composition, hydration levels, and the temperature of the sauna. While this calorie burn is comparable to light to moderate exercise, it’s important to understand that sauna induced calorie burn isn’t a replacement for traditional workouts. The weight loss you experience in a sauna is water weight, and after you polish off a large glass of water following up your session, you may find you’re right back to where you started weight wise.

Limitations of Using a Sauna for Weight Loss

This may sound like conflicting information, saunas do in fact burn calories but are not necessarily helping you learn lose weight. Let’s break down what this means exactly and the considerations to have when it comes to weight loss and saunas.

1. Water Weight vs. Fat Loss

Most of the immediate weight loss from a sauna session comes from water loss through sweating, not fat burning. Once you rehydrate, much of that weight will return.

2. No Muscle Engagement

Unlike exercise, which builds muscle and boosts metabolism, sitting in a sauna doesn’t engage muscles or improve cardiovascular endurance.

3. Temporary Metabolic Boost

While saunas can temporarily increase your metabolic rate, the effect doesn’t last long enough to replace the benefits of regular physical activity and proper nutrition. They are really more of a complimentary effort to an overall holistic lifestyle focused on wellness.

4. Overheating & Dehydration Risks

Spending too much time in a sauna can lead to dehydration, dizziness, or heat exhaustion. This may lead to sluggish feelings, making it much harder to want to workout and move the body properly. Always hydrate properly before and after a session.

The Best Weight Loss Strategy: Sauna + Healthy Habits

Saunas can be a powerful tool in a well-rounded weight loss plan, but they work best when combined with:

1. Regular Exercise

• Strength training and cardio burn more calories and build lean muscle, increasing your resting metabolism.

• Incorporating sauna sessions after workouts may aid recovery and circulation, helping you stay consistent with your fitness routine but they are not going to be the source of your calories burned.

2. Balanced Nutrition

• Weight loss comes down to a caloric deficit which means burning more calories than you consume.

• Focus on whole foods, lean proteins, healthy fats, and complex carbs to fuel your body properly.

3. Hydration & Recovery

• Since saunas promote sweating, staying properly hydrated is essential for both performance and weight management.

• Using saunas post-workout may help reduce muscle soreness and keep you feeling refreshed for your next session.

The Verdict: Can a Sauna Help You Lose Weight?
