How Much Weight Can You Lose in a Week with a Sauna Suit? The Ultimate Guide
Hey there! I‘m Lillie, a home improvement expert who also happens to be fascinated by health and fitness. Lately, I‘ve had lots of readers asking if sauna suits really help you lose weight quickly. I did some deep research and wanted to share everything I learned with you in one super detailed guide.
Get ready for stats, science-backed facts, and plenty of tips from my own experience trying sauna suits!
How Exactly Do Sauna Suits Work?
Sauna suits are made of thick, non-breathable neoprene or vinyl that trap heat close to your body and make you sweat profusely during exercise. Think of the sauna suits as creating a portable sauna around your body!
The trapped heat causes your core body temperature to rise, making your heart beat faster to cool you down. Your sweat glands also go into overdrive!
This combination of increased heart rate and sweating makes your body burn extra calories as it tries to reach a normal temperature again.
Most experts agree that wearing a sauna suit during cardio can boost your calorie burn by around 30-50% compared to exercising normally (source). So if you‘d usually burn 300 calories by walking for an hour, wearing a sauna suit could increase that to 390-450 calories burned in the same time.
The excessive sweat you produce also causes you to lose water weight as the water leaves your body through perspiration.
This is why sauna suits provide that tempting quick and drastic weight loss in the short term. But remember – it’s mostly just water!
Just How Much Weight Can You Lose in 1 Week?
Now, let’s get to the real question – exactly how much weight can you expect to lose by wearing a sauna suit for a week while exercising?
Here are the typical results based on scientific studies:
-
In one study of wrestlers using sauna suits 2 hours daily for 5 days, the average water weight loss was 5 lbs (2.3 kg) (source).
-
A similar 6 day study on runners wearing sauna suits for 30 minutes during workouts showed an average weight loss of 3.7 lbs (1.7 kg) (source).
-
Most studies show that wearing a sauna suit 3 times per week during 30 minute workouts leads to about 2-5 lbs (0.9-2.3 kg) of water weight loss over a 1 week period (source).
However, your individual results can vary quite a bit based on factors like:
Your Starting Weight
The more overweight you are, the more you tend to sweat and the faster you‘ll shed water weight using a sauna suit.
If you‘re very overweight, you may lose on the higher end of the scale – maybe around 4-5 lbs in a week.
But for someone who is already at a healthy weight, they may only lose 1-2 lbs over the same period.
Your Diet
What you eat (or don‘t eat) has a BIG impact on water weight loss.
Eating a diet higher in processed carbs and sodium causes your body to retain more water.
So try to cut out junk food, reduce sodium intake, and follow a lower carb diet to enhance water weight loss from sauna suit sweating.
Exercise Intensity
Vigorous cardio that really gets your heart pumping results in more sweating and greater water loss compared to low intensity exercise.
So push yourself with challenging workouts like HIIT, running, and bootcamp-style classes to maximize the sauna suit benefits.
Environment
Hot and humid weather essentially turbocharges your sauna suit!
Working out outdoors during the summer will make you sweat buckets more than exercising in an air conditioned gym.
Take advantage of the heat and get outside for your workouts with a sauna suit when you can.
Hydration Status
This one is counterintuitive, but drinking MORE water actually helps you flush out excess water from your body.
Aim for at least 16 oz (500ml) before, during and after workouts so you sweat out more with the sauna suit.
Your Fitness Level
People who workout frequently tend to sweat more than deconditioned beginners.
So if you’re new to exercise, you may lose less than a seasoned gym rat utilizing a sauna suit for the first time.
Using a Sauna Suit Safely and Effectively
While sauna suits provide the tantalizing prospect of accelerated weight loss, they do carry health risks if used incorrectly.
It’s so important to use proper safety precautions. Here are my top tips:
Stay Hydrated
Drink at least 16 oz (500ml) of water before, during and after your sauna suit workout to avoid dehydration.
I also suggest sipping on a sports drink or electrolyte tablets in your water to replenish the minerals lost through heavy sweating.
Don’t Overheat
Listen to your body carefully during workouts. Take breaks whenever you feel yourself overheating or getting lightheaded.
And have a plan for how to quickly cool down – whether it’s removing layers, hydrating, or seeking shade.
Better safe than sorry when it comes to overheating!
Limit Sessions to 30 Minutes
Research shows that sauna suit sessions longer than 30 minutes provide minimal extra water loss but substantially increase risk of overheating and dehydration (source).
So keep your workouts short and remove the suit immediately if you feel unwell.
Talk to Your Doctor First
Anyone with pre-existing health conditions like diabetes, hypertension, heart disease, etc. should get medical clearance before using a sauna suit.
The doctor can advise on any precautions to keep you safe. Don’t take chances with your health!
Exercise Lightly
Vigorous, intensive cardio requires caution with a sauna suit due to overheating risk. Focus on lower intensity activities like walking.
Save the hardcore HIIT workouts for your non-sauna suit days!
Weigh Yourself First
Sauna suits are only recommended if you have weight to lose.
If you‘re underweight or at a healthy weight, avoid using a sauna suit – it‘s unnecessary and risky.
Eat in a Calorie Deficit
No matter what the ads claim, sauna suits alone won’t cause meaningful fat or weight loss. You need a calorie deficit for that!
So be sure to reduce your calorie intake below your Daily Total Energy Expenditure along with the sauna suit to maximize real results.
How to Get the Most Out of Your Sauna Suit
These tips will help accelerate your temporary water weight loss:
- Exercise outdoors on hot/humid days
- Combine HIIT and steady state cardio workouts
- Follow a low-carb diet to reduce water retention
- Take occasional ice baths to further boost calorie burn
- Get 8 hours of sleep nightly to recover properly
- Consider alternating day fasting to increase calorie deficit
- Engage your core during cardio for greater sweat response
- Wear moisture-wicking fabrics over the suit to soak up sweat
With this comprehensive approach, you can probably lose up to 5 pounds in a week through increased water loss and calorie burn.
But always listen to your body and don‘t overdo it! Slow and steady consistency is key.
Limitations to Be Aware Of
While sauna suits have temporary benefits, it’s vital to be realistic about their limitations too:
Water Weight Comes Back Quickly
Any water weight you lose from sweating in the suit will rapidly return after you rehydrate normally again.
The number on the scale goes right back up! This is why sauna suits only provide short-term water loss.
No Direct Fat Loss
Unfortunately, sauna suits do not directly burn stored fat – they simply make you lose water weight via sweating.
You still need to be in an overall calorie deficit through diet and exercise to actually lose body and belly fat.
Adaptation Happens Fast
Research shows the body adapts to sauna suits within 1-2 weeks of consistent use, after which the water weight benefits decrease substantially (source).
So they lose effectiveness quickly.
Health Risks
Using sauna suits too frequently or intensely can lead to dehydration, overheating, dizziness, electrolyte imbalance and impaired recovery.
It’s so important to use proper caution and not overdo it.
No True Fitness Benefits
Despite claims, sauna suits don’t actually improve cardio endurance or boost strength and muscle growth compared to exercise without them.
Don’t use sauna suits as a replacement for proper training.
The takeaway? Approach sauna suits as a supplemental tool for accelerated temporary water weight loss, not a fix-all solution in themselves.
Answers to Common Sauna Suit Questions
Here are direct answers to some of the most frequently asked questions I get:
