Sauna vs Steam Room Weight Loss: 2025 Study Results

Struggling to shed those stubborn pounds? You’ve tried diets, hit the gym, and maybe even dabbled in trendy workouts, but the scale still isn’t budging. What if a relaxing, sweaty session could give your weight loss journey a boost? Enter infrared saunas and steam rooms—two wellness powerhouses that promise more than just relaxation. But do infrared saunas work for weight loss, and how do they stack up against steam rooms?

In this article, we’ll dive into the latest 2025 research to uncover the truth about infrared saunas and steam rooms for weight loss. We’ll explore how they work, what science says, and which option might be your ticket to a slimmer, healthier you. Whether you’re curious about do infrared saunas work or wondering if a steam room is better, we’ve got you covered with practical insights and expert-backed data.

What Are Infrared Saunas and How Do They Work?

Unlike traditional saunas that heat the air around you, infrared saunas use infrared light to directly warm your body. This creates a gentler heat—typically between 120°F and 140°F—compared to the scorching 150°F to 190°F of traditional saunas. The result? A deeper sweat at a more comfortable temperature, which many find easier to tolerate.

Infrared light penetrates your skin, raising your core body temperature and potentially triggering benefits like detoxification, improved circulation, and—yes—weight loss. Curious about the mechanics? Check out our detailed guide on what is an infrared sauna for a deeper dive.

Sauna vs Steam Room: Key Differences

Before we get to the weight loss showdown, let’s clarify how infrared saunas and steam rooms differ:

Heat Type: Infrared saunas deliver dry, radiant heat; steam rooms provide moist, humid heat.
Temperature: Infrared saunas operate at 120°F to 140°F, while steam rooms hover around 110°F to 120°F but feel hotter due to high humidity (100%).
Heating Method: Infrared saunas use light to heat your body directly; steam rooms rely on a steam generator to fill the space with hot, humid air.
Experience: Infrared saunas feel like a warm, cozy hug; steam rooms are like stepping into a tropical mist.

These differences impact their effectiveness for weight loss and other health benefits. Want to explore more? Our sauna vs steam room page breaks it down.

Do Infrared Saunas Work for Weight Loss?

Let’s cut to the chase: do infrared saunas work for shedding pounds? The answer is a cautious yes, but it’s not a magic bullet.

A 2025 study from Binghamton University offers compelling evidence. In a two-phase trial, participants used a Clearlight Premier IS-3 infrared sauna:

Phase 1: Three 45-minute sessions per week for 16 weeks led to an average 4% body fat reduction.
Phase 2: Five 30-minute sessions per week for 8 weeks resulted in about 0.5% body fat loss per week, totaling roughly 4% overall.

The secret lies in how infrared saunas raise your core body temperature, mimicking the effects of moderate exercise. This process may stimulate human growth hormone (HGH) production, which aids fat breakdown. The study also noted that evening sessions amplified fat loss, possibly due to circadian rhythm effects.

However, the study didn’t control for diet or exercise, so results aren’t solely attributable to the sauna. Still, the data suggests infrared saunas can be a valuable tool when paired with a healthy lifestyle. Learn more about their potential at our infrared sauna benefits page.

Steam Rooms and Weight Loss: What’s the Deal?

Steam rooms, with their steamy, humid environment, are a staple in spas and gyms. But do they help with weight loss? The short answer: not as much as infrared saunas.

Steam rooms promote sweating, which can lead to temporary weight loss—think 1 to 2 pounds per 30-minute session. But this is mostly water weight, not fat. Once you rehydrate, the scale bounces back. A 2023 article from Healthline confirms that while steam rooms raise your heart rate (similar to light cardio), their direct impact on fat loss is minimal. They’re better suited for relaxation, muscle recovery, and skin health.

Infrared Sauna vs Steam Room: Which Is Better for Weight Loss?

The 2025 Binghamton study gives infrared saunas the edge for fat loss. Here’s why:

Deeper Heat Penetration: Infrared light targets fat cells beneath the skin, potentially releasing stored toxins and aiding fat breakdown. Steam rooms primarily cause water weight loss.
Metabolic Boost: Infrared saunas mimic exercise by raising core body temperature, which may enhance metabolism and HGH production. Steam rooms offer a milder cardio effect.
Comfort and Frequency: Lower temperatures in infrared saunas make them easier to use regularly, which is key for consistent results.

That said, steam rooms have their perks, like improving respiratory health and hydrating the skin. If your goal is strictly weight loss, infrared saunas are the smarter bet. Curious about other differences? Check out our difference between sauna and steam room page.

Maximizing Weight Loss with Infrared Saunas

To get the most out of an infrared sauna for weight loss, follow these research-backed tips:

Frequency: Aim for 3–5 sessions per week, as seen in the Binghamton study.
Duration: Stick to 30–45 minutes per session for optimal results.
Timing: Evening sessions may enhance fat loss due to hormonal responses.
Hydration: Drink water before, during, and after to prevent dehydration.
Lifestyle: Pair sauna use with a balanced diet and regular exercise for lasting results.
