Saunasuits / Sweatsuits

Sweatsuits or Saunasuits are waterproof clothes designed to make you sweat a lot during exercise and help your body to detoxify the skin, enhance immune system, and reduce stress.

The reason why saunasuits are so famous is this little twist: They make you sweat profusely. If you don't get soaking wet inside during exercise, then you're not doing it right.

Weight Loss

The primary benefit of using saunasuits is that they can help you lose weight, but only for the short term through water loss, which is why they are commonly used by boxers and weightlifters before competing for such an event. Because of all the liquid lost, your weight on the scales may suddenly look very optimistic, The weight that is lost is immediately gained right back once you are rehydrated again. In the long term, there are is no weight loss caused by this suit.

Saunasuit Types

Sauna suits are a relatively new form of fashion, though they aren’t exactly designed to look fashionable. They usually come in a two-piece setup similar to a typical sweat suit or tracksuit, with elastic waistbands, ankles, and wrists. The suits vary in their construction material, but most are designed to prevent sweat or heat from escaping the body.

Sauna suits are also built to be durable to standup to the demands of various forms of workouts. As such, they are not solely designed for use simply sitting in a sauna. Sauna suits can benefit a variety of individuals and can help just about anyone shed the body of toxins and help relax and calm their muscles.

Saunasuit Fabrics

Saunasuits are made of either rubberised vinyl or nylon. These materials aren’t breathable or let vapour through which makes you sweat even more. They soak up almost no water. Choose one that feels good on your skin when wet.

How Does a Saunasuit Work?

They are like a sauna you can wear. When you run, or do any workout, your body heats up. Adjusting to the rise in core temperature, your body produces sweat that would then evaporate and cool you down. Add a saunasuit and we may just screw up the system big time.

When you exercise in a saunasuit, sweat is trapped and unable to evaporate. Hence, the body will produce even more sweat in a desperate attempt to prevent overheating. The profuse sweating can give that cleansing or purifying feel you get after a sauna session.

How to wear a Saunasuit?

Put on your saunasuit like any other normal article of clothing. Don’t tuck the top into the pants or water will collect above your waistline.

Adjust the saunasuit so that the closures fall on your ankles, waist, wrists, and collarbone. If it has a hood, put it up and tie it close around your face.

Under your suit, you could wear some body-hugging and moisture wicking clothes, such as sports shirts and shorts.

After exercise, rinse the sweat off your suit and your body. Turn the suit inside out for that.

Does working out in a Saunasuit burn more Calories?

Unfortunately, no, unless you swim in it. Sweat is mostly water and salt, not fat. Working out in a saunasuit will not help you burn more calories. You may initially lose water weight from perspiring more, but you are not actually losing more body fat than doing the same exercise in sportswear. The water weight you lose will quickly be replaced once you start drinking water following your workout.

Do Swimmers Sweat While They Train?

Yes, a lot. It is tempting to think that because we train in water and because we don’t see any sweat streaming out of our pores that we don’t need to pay attention to our water bottle over the course of our swimming workout.

You can definitely sweat while swimming. Sweating is a biological function used by the body to cool itself down. That means, during high-intensity workouts, the body will break a sweat to cool down, even in the water. However, swimmers are less likely to notice the sweat because the water washes it off immediately.

Strength Training Burns Calories

A saunasuit is also good for resistance swim training. The best way to burn more calories is to participate in water activities that will raise your heart rate, as well as strength training activities that target your large muscle groups.

Swimming in your saunasuit burns more calories than sweating in it, as you have to work harder to swim each length, due to the drag resistance of the suit in the water. It spreads the resistance load evenly over your body which is better than weight lifting. Although not strictly waterwear, you can use saunasuits for many water sports whilst enjoying their health benefits.

Stay Hydrated

Working out in a saunasuit on can lead to dehydration and overheating. You lose a lot of fluid when exercising which needs to be replaced. It is vital that you are sufficiently hydrated before beginning your exercise routine and also that you remember to hydrate during and after the routine as well. Drink at least half a litre of water before starting your exercise routine and then again after you finished your routine.

You can sweat as much as your hydration will allow. That means you can just keep on sweating until your water runs out. Then you are in deep trouble.

At room temperature your body sweats around half a litre of sweat an hour, but it depends on the surrounding temperature, humidity, level and intensity of the activity. This can go up to a 3 litres during exercise, when you are stressing hard about something, or when it is hot outside.

Given a certain exercise, you actually sweat the same amount on a cold, dry day as you do on a humid day. The difference is that in high humdity the sweat isn't able to evaporate as quickly because of how much moisture is already in the air.

Even if you are only 2% dehydrated, your performance will start to drop. When training in warmer environments, like indoor pools, you are particularly susceptible.

Dehydration

The warning signs of dehydration can be especially difficult for swimmers to notice. Dry mouth? A little bit of pool water in the mouth covers that up in a hurry. Lots of sweat? Can’t really tell. Overheating? Let me just dunk my head under the water for a couple seconds to cool off.

The double whammy of thinking that because we don’t need to hydrate because we swim in a pool, and because the symptoms of dehydration often end up going unnoticed until much later, makes it critical for swimmers to stay on top of their fluid intake.

Most professionals recommend that you do not do any prolongued dry exercise while wearing a saunasuit. The National Collegiate Athletic Association has banned the use of saunasuits in 1998 after the death of two wrestlers who exercised while wearing them, due to excessive dehydration.
