In the quest for better health and a slimmer physique, infrared saunas are becoming a hot topic—literally. Unlike traditional saunas, these high-tech versions use infrared light to heat your body directly, promising a host of wellness benefits. But can they really help you lose weight?
Let’s explore the science behind infrared sauna weight loss, including what studies say, how the process works, and whether it’s worth adding to your health routine.
What Is an Infrared Sauna?
An infrared sauna uses infrared heaters to emit light that your body absorbs as radiant heat. This heat penetrates deeper than the hot air in traditional steam saunas, warming your body from the inside out.
Because they operate at lower temperatures (typically between 110°F and 140°F), infrared saunas are generally more comfortable for longer sessions. But it’s not just about comfort—advocates believe this method may enhance calorie burning, detoxification, and even boost metabolic rate.
The Science Behind Infrared Sauna Weight Loss
Increased Caloric Burn
Several sources suggest that a session in an infrared sauna may help you burn a significant number of calories. According to a study published in the Journal of the American Medical Association, a 30-minute infrared sauna session can burn as many as 600 calories [source]. The reason? As your body works to cool itself, your heart rate, cardiac output, and metabolic rate increase—similar to moderate exercise.
This effect mimics what happens during aerobic workouts, making infrared sauna weight loss an appealing option for those with limited mobility or recovering from injuries.
Water Weight and Sweating
Sweating helps your body eliminate excess water and salt. A single session in an infrared sauna can make you sweat profusely, leading to temporary weight loss. However, it’s essential to note that this is mostly water weight, not fat loss. Once you rehydrate, that weight typically returns.
Still, regular use may help with overall body composition when combined with a healthy lifestyle, as shown in this 2019 study from Complementary Therapies in Medicine [source].
Improved Circulation and Metabolism
Infrared heat increases circulation, which can improve oxygen delivery and nutrient transport throughout the body. A faster metabolism means your body burns more calories even at rest. One study in Alternative Medicine Review found that subjects who used infrared saunas regularly experienced improvements in cardiovascular health and basal metabolic rate.
This provides another mechanism through which infrared sauna weight loss might be possible over time.
Infrared Saunas vs. Traditional Saunas for Weight Loss
While both types of saunas cause sweating and temporary water loss, infrared saunas have a few distinct advantages when it comes to potential weight loss:
- Lower temperatures make sessions more tolerable, especially for beginners.
- Deeper tissue penetration may help mobilize subcutaneous fat more effectively.
- Longer session duration allows for more sustained cardiovascular stimulation.
One comparative study by Mayo Clinic Proceedings found that infrared therapy could enhance detoxification and reduce inflammation more effectively than traditional saunas, possibly leading to more long-term benefits.
Realistic Expectations: What Infrared Saunas Can and Can’t Do
Let’s be clear—infrared sauna weight loss is not a magic bullet. If your lifestyle includes poor diet choices and a sedentary routine, an infrared sauna alone won’t lead to dramatic weight loss. However, as part of a holistic approach that includes exercise, healthy eating, and hydration, it can be a valuable complementary tool.
What You Can Expect:
✅ Calorie burn similar to cardio
✅ Detoxification through sweat
✅ Improved circulation and metabolic boost
✅ Temporary water weight loss
✅ Potential long-term body composition changes
How Often Should You Use an Infrared Sauna for Weight Loss?
For best results, experts recommend using an infrared sauna 3–4 times per week, with sessions lasting 30 to 45 minutes. Always stay hydrated and listen to your body. Start with shorter sessions if you’re new, and gradually increase duration as you acclimate.
A wellness report by Cleveland Clinic suggests that regular use can support a range of health outcomes, including weight management, especially when combined with diet and exercise.
Safety Tips and Contraindications
Before you begin your infrared sauna weight loss journey, consult with your healthcare provider, especially if you have underlying health conditions such as cardiovascular disease or low blood pressure. Pregnant individuals and those on certain medications should avoid sauna use.
Always prioritize safety by:
- Staying hydrated
- Cooling down properly
- Avoiding alcohol before use
- Not exceeding recommended session lengths
Final Thoughts: Is It Worth Trying?
So, can infrared saunas help with weight loss? Science says yes—with caveats. While the weight you lose during a single session may largely be water, consistent use can support fat loss, improved metabolism, and better overall health when paired with lifestyle changes.
If you’re already investing in wellness practices like nutrition and movement, adding an infrared sauna to your routine could help amplify your results. It’s not a miracle solution—but it might just be the boost your wellness routine needs.
