Sauna suits, designed to boost internal temperature and induce sweating, have evolved significantly. No longer just the PVC or nylon nightmares of the past, modern sauna suits are constructed from materials like neoprene. While proponents tout benefits ranging from enhanced calorie burn to improved heat acclimation, it's crucial to separate fact from fiction and understand the potential risks involved.
What is a Sauna Suit?
A sauna suit is essentially a waterproof tracksuit designed to retain body heat and perspiration during workouts. Made from non-breathable materials, such as neoprene, PVC, or nylon, these suits create a thermogenic environment, increasing sweat output. Some come as full-body suits, while others are separates - shirts and pants - that can be worn together or individually.
Purported Benefits of Sauna Suits
Advocates of sauna suits claim a range of benefits, including:
- Increased Calorie Burn: Some studies suggest a marginal increase in calorie expenditure when wearing a sauna suit during exercise. A 2022 study in The Journal of Strength and Conditioning Research found that participants burned an additional 23 calories per hour when wearing a sauna suit during high-intensity interval exercise (HIIE).
- Enhanced Fat Oxidation: Fat oxidation, the process by which the body breaks down and uses fat stores, may also be increased with sauna suit use. The same 2022 study noted a significant increase in fat oxidation for 60 minutes after HIIE while wearing a sauna suit.
- Improved Heat Acclimation: Training in a sauna suit can potentially help the body adapt to warmer climate conditions. A 2017 study found that participants who trained for 14 days in a sauna suit showed improved VO2 max, ventilatory threshold, and time trial performance.
- Increased VO2 Max and Ventilatory Threshold: The aforementioned 2017 study also demonstrated improvements in VO2 max (the body's oxygen uptake) and ventilatory threshold (the point at which oxygen delivery to the muscles limits exercise ability).
The Science Behind the Sweat
The primary mechanism behind these purported benefits lies in the suit's ability to trap heat. As you exercise, heat and sweat build up inside the suit, leading to:
- Increased Physiological Strain: Exercising in a sauna suit increases physiological strain.
- Elevated Heart Rate and Oxygen Use: Research confirms that exercising in a sauna suit raises heart rate, oxygen use, and perceived effort.
- Greater Sweat Losses: Sauna suits induce larger sweat losses compared to exercising without them.
The Reality of Weight Loss
It's important to distinguish between water weight loss and actual fat loss. While sauna suits can lead to a rapid drop in weight due to increased perspiration, this is primarily fluid loss that will be regained upon rehydration.

True fat loss occurs when you consistently burn more calories than you consume. A sauna suit may contribute to this process by:
- Creating a Thermogenic Environment: By trapping body heat, the suit forces the body to work harder to cool down, potentially increasing caloric expenditure.
- Increasing Workout Intensity: The added heat can make workouts feel more intense, leading to a greater overall calorie burn.
Potential Risks and Precautions
Despite the potential benefits, sauna suits come with significant risks that require careful consideration:
- Dehydration: Sauna suits increase perspiration, which can quickly lead to dehydration if fluids are not adequately replenished.
- Hyperthermia (Overheating): By preventing the body from cooling itself, sauna suits can cause hyperthermia, a dangerous condition that can escalate rapidly.
- Electrolyte Imbalance: Excessive sweating can deplete electrolytes, potentially leading to muscle cramps and other complications.
- Cardiovascular Strain: Exercising in a sauna suit can put extra stress on the cardiovascular system.
To mitigate these risks, it's crucial to:
- Consult a Medical Professional: Talk to your doctor before using a sauna suit, especially if you have any underlying health conditions.
- Stay Hydrated: Drink plenty of water before, during, and after workouts in a sauna suit.
- Avoid Extreme Temperatures: Do not wear a sauna suit in hot workout conditions or weather.
- Limit Duration: Start with short sessions (10-15 minutes) and gradually increase the duration as your body adapts.
- Listen to Your Body: Stop exercising immediately if you experience any symptoms of overheating or dehydration.
Sauna Suits and Heat Acclimation
One area where sauna suits show promise is in heat acclimation. Athletes training for events in hot climates may use sauna suits to prepare their bodies for the challenging conditions.
A study by the American Council on Exercise (ACE) found that athletes who trained in sauna suits for two weeks saw a 3% increase in their speed. The participants also lost significantly more weight through sweat and had lower core temperatures during heated assessments.
Heat acclimation leads to several physiological adaptations, including:

- Augmented Sweating: The body becomes more efficient at sweating, allowing for better heat dissipation.
- Reduced Body Temperature: The body's core temperature decreases, increasing the capacity for heat storage.
- Improved Endurance Performance: Heat-acclimated individuals tend to perform better in hot environments due to their improved ability to regulate body temperature.
Sauna Suits vs. Traditional Saunas
While both sauna suits and traditional saunas raise core body temperature, they do so in different ways. Saunas use steam or dry heat to create a hot environment, while sauna suits trap the body's own heat during exercise.
Some proponents suggest that saunas offer similar health benefits to exercise, but research in this area is limited. Studies have shown that regular sauna use can lower blood pressure, reduce symptoms of congestive heart failure, and improve chronic pain. However, more research is needed to determine whether sauna suits offer the same benefits as traditional saunas.
Sauna Suits in Specific Sports
Historically, sauna suits have been popular among athletes in sports like boxing, MMA, and wrestling, where rapid weight loss is sometimes necessary to meet weight class requirements. However, some athletic governing bodies, such as the NCAA, prohibit the use of sauna suits due to safety concerns.
In these sports, sauna suits are typically used to shed water weight temporarily before competitions. It's crucial to note that this practice should be approached with extreme caution and under the guidance of a medical professional to avoid dehydration and other health risks.
The Verdict: A Tool, Not a Magic Bullet
Sauna suits are not a magic bullet for weight loss. While they may offer some benefits in terms of increased calorie burn, fat oxidation, and heat acclimation, they also come with significant risks.

The decision to use a sauna suit should be made in consultation with a medical professional or certified fitness trainer. It's essential to prioritize safety and use the suit responsibly, focusing on hydration and listening to your body's signals.
Beyond Sauna Suits: Sustainable Weight Loss Strategies
For lasting weight loss and improved health, focus on sustainable strategies such as:
- Consistent Training: Engage in regular physical activity that you enjoy.
- Building Muscle: Incorporate strength training to increase muscle mass, which boosts metabolism.
- Fueling Well: Follow a balanced diet that provides adequate nutrients and supports your activity level.
- Staying Hydrated: Drink plenty of water throughout the day.
