Why Sweating More Is Actually the Point: The Real Benefits of Infrared Fitness Studios and Sauna Sessions
If you have ever walked out of a ROWDY class absolutely drenched and thought that felt different, you are not imagining things.
Training in an infrared-heated environment is not just a vibe, although the vibe is excellent. It is a fundamentally different way of moving your body, and the science behind it is genuinely compelling. The sweat you produce in our studio is not just a byproduct of hard work. It is part of the work itself.
Here is everything you need to know about what infrared heat actually does, why sweating matters more than most people realize, and why combining an infrared fitness class with a sauna session is one of the smartest things you can do for your body.
What Is Infrared Heat, and How Is It Different from a Regular Heated Studio?
This is the most common question we get from people trying us for the first time, and it is a good one.
Traditional heated fitness studios raise the temperature of the air in the room. You feel hot because the air around you is hot. Infrared heat works differently. Instead of heating the air, infrared light waves penetrate directly into your muscle tissue, warming your body from the inside out. The result is a more even, more effective heat that your body can actually use, rather than just sit inside.
At The ROWDY Mermaid, our classes are heated to up to 98 degrees using far-infrared technology. That temperature might sound intense, but because the heat is working with your body rather than just around it, most people find it more tolerable and more productive than a traditional hot room. Your muscles are warm from the start. Your circulation is already elevated. Your body is primed and ready to work before you even pick up a weight.
What Are the Benefits of Working Out in an Infrared Studio?
Your Muscles Perform Better When They Are Warm
Cold muscles are inefficient muscles. When your body temperature rises, blood vessels dilate, oxygen delivery to working muscles increases, and your muscle fibers become more pliable and responsive. This means better range of motion, more powerful contractions, and a lower risk of strain or injury right from the beginning of your workout.
In a traditional gym setting, it can take 10 to 15 minutes of movement before your muscles are truly warm and ready to perform at full capacity. In an infrared studio, that process is accelerated before class even begins. Every rep, every set, every movement you perform in that room is happening at a higher level of physiological readiness than it would in a standard environment.
You Burn More Calories
Your body works hard to regulate its internal temperature. When you exercise in an infrared-heated environment, your cardiovascular system is simultaneously managing the demands of the workout and the demands of the heat, which means your heart rate climbs faster and stays elevated longer. Research suggests that infrared heat exposure can significantly increase calorie burn compared to the same workout performed at room temperature, because your body is doing double duty the entire time.
This does not mean you should rely on heat alone. The combination of genuine effort in class plus the thermal effect of infrared is what produces results. But it does mean that every class you take in our studio is working harder for you than a comparable workout somewhere else.
Your Recovery Is Faster
This is where infrared heat really separates itself, and where the research is most convincing.
A study published in the journal Biology of Sport by researchers at the University of Jyväskylä in Finland found that a post-exercise infrared sauna session significantly improved recovery of neuromuscular performance and reduced muscle soreness following resistance training. In plain terms: your muscles bounce back faster, and you hurt less the next day.
The mechanism behind this is increased circulation. When infrared heat dilates your blood vessels and drives blood flow to your muscles, it accelerates the removal of metabolic waste products like lactic acid that accumulate during hard training. The faster those waste products are cleared, the faster your muscles can repair and rebuild. This is exactly why so many serious athletes and coaches have integrated infrared heat into their recovery protocols, and why our infrared sauna sessions at ROWDY are not just a luxury. They are strategy.
Inflammation Goes Down
Intense exercise creates micro-tears in muscle tissue, which is the process that leads to muscle growth, but it also triggers a localized inflammatory response. Chronic inflammation, when your body stays in that state too long or too often, is where things go wrong: persistent soreness, slower progress, higher injury risk.
Infrared heat has been studied for its anti-inflammatory effects, with research pointing to its ability to reduce inflammatory markers in the body following exercise. For anyone training multiple times per week, managing inflammation is not optional. It is the difference between being able to keep showing up and being forced to take time off.
Your Skin Benefits Too
Increased circulation driven by infrared heat means more blood flow to your skin as well as your muscles. This supports collagen production, improves skin tone, and gives your complexion that post-class glow that you genuinely cannot fake. Research has also pointed to infrared heat's potential role in supporting lymphatic drainage, which helps reduce the appearance of puffiness and water retention over time.
What Are the Benefits of Infrared Sauna Sessions?
A standalone infrared sauna session is a completely different experience from a workout, but the benefits are just as real. At ROWDY, our 30-minute sauna sessions are available to book on their own, and they are one of the most underused tools in our studio.
Cardiovascular Health
A landmark review published in Mayo Clinic Proceedings found that regular sauna use produces cardiovascular responses in the body that closely resemble those produced by moderate to high-intensity physical activity. Your heart rate rises, your blood vessels dilate, and your cardiovascular system gets a genuine workout without any of the muscular demand.
The same body of research, which drew on long-term Finnish cohort studies, found that people who used a sauna four to seven times per week had significantly reduced risk of cardiovascular mortality and a substantially lower risk of developing high blood pressure over time. These are not small effects. This is meaningful, measurable cardiovascular protection from consistent heat exposure.
Mental Health and Mood
This one is close to our hearts at ROWDY because we have always believed that more sweat equals stronger mental health. Now the science is catching up to what we have known all along.
A 2024 study of more than 20,000 adults found a measurable link between heat exposure and improvement in depressive symptoms, with researchers identifying an immune-signaling molecule called Interleukin-6 as a potential mechanism: an acute spike in IL-6 following heat exposure appears to correlate with how much depressive symptoms improve. Separate research published in peer-reviewed medical literature found that sauna use showed potential in the treatment of depression by improving objective depression scores.
Heat exposure also triggers the release of endorphins, the same mood-boosting neurochemicals your body produces during exercise. This is why you walk out of a sauna session feeling lighter, calmer, and more like yourself than when you walked in. It is not a coincidence. It is chemistry.
Brain Health and Longevity
The same Finnish research that tracked cardiovascular outcomes also found that frequent sauna use was associated with a dramatically reduced lifetime risk of developing dementia, with researchers pointing to heat shock proteins as a likely neuroprotective mechanism. Heat shock proteins are produced by your body in response to thermal stress and appear to play a protective role in brain cell function over time.
Regular infrared sauna use is, in effect, a long-game investment in the health of your brain. The fact that it also feels incredible is a bonus.
Stress and Cortisol
The parasympathetic nervous system, your body's rest-and-recover mode, is activated during and after infrared sauna sessions. This counteracts elevated cortisol, the stress hormone that, when chronically elevated, contributes to weight gain, poor sleep, immune suppression, and a general feeling of being completely overwhelmed. A 30-minute sauna session is one of the most efficient ways to bring your nervous system back to baseline after a hard day, a hard week, or a hard workout.
Why Combining an Infrared Workout with a Sauna Session Is the Smartest Move You Can Make
The research on this is clear: you stand to gain the most from infrared heat when you do both.
A study comparing eight weeks of exercise alone versus exercise combined with sauna found that the exercise plus sauna group showed greater improvement in cardiovascular fitness, total cholesterol, and blood pressure than the exercise-only group. Researchers also found a synergistic effect on cardiovascular mortality risk when aerobic exercise and regular sauna use were combined, meaning the two together produce outcomes that neither produces alone.
The protocol that experts recommend is simple: finish your workout, then spend 20 to 30 minutes in the sauna. Your heart rate is already elevated, your circulation is already pumping, and your muscles are primed to absorb the recovery benefits of the heat. This is the sequence we have built into our studio from the beginning, and it is why so many of our members book a sauna session immediately after class.
Common Questions About Infrared Fitness and Sauna
Is infrared heat safe? Yes, for the vast majority of healthy adults. Infrared heat operates at a lower temperature than traditional saunas and heats your body directly rather than the surrounding air, making it more tolerable for most people. As with any form of exercise or heat exposure, staying hydrated is essential. If you have an underlying health condition, check with your doctor before starting.
How much water should I drink before an infrared class or sauna session? Plan to drink at least 16 to 20 ounces of water in the hour before your session, and continue hydrating immediately after. You will sweat significantly more than you would in a standard workout, and replacing that fluid is not optional. Electrolytes are worth considering if you are training multiple days in a row.
Will I actually sweat more in an infrared studio? Yes. The infrared heat activates your sweat response earlier and more intensely than a room-temperature workout. This is by design. Sweating is one of your body's most important mechanisms for thermoregulation, waste removal, and skin health. Sweating more, done correctly and with proper hydration, is a feature of infrared training, not a side effect
How often should I use the infrared sauna? The research on frequency consistently shows that more is better, up to a point. Using the sauna two to four times per week produces meaningful cardiovascular and recovery benefits. Daily use is generally safe for healthy individuals. Starting with two sessions per week and building from there is a reasonable approach for most people.
Can I use the infrared sauna if I am not working out that day? Absolutely. A standalone sauna session is a complete recovery and wellness tool in its own right. Many of our members use it on rest days specifically because it supports the recovery process without adding muscular stress. It is also an excellent tool for managing stress, improving sleep, and maintaining the cardiovascular benefits of your training between sessions.
