The last sauna belt that we recommend you to use comes from Velform and it’s a renowned product that has pleased many users. The quality leather it’s made of guarantees that it will last for many years of use and that the heat will be evenly distributed. Still, it will not feel as hot as the other models so it’s best to use it as a relaxation and detoxification means rather than as a weight loss aid.

How to Operate a Slim Belt

These belts are incredibly easy to operate, which is good news for those who are interested in using them. In order to use this product, all that you have to do is to place it around your abdominal area and adjust it so you get a snug fit. Fitting is the most important part, so make sure it fits you perfectly and offers you a comfortable experience while wearing it. After you put on the item, you must adjust the temperature as you please. What we recommend is that you take it slow in your first sessions, and try to not exceed 120°F for your body to get accustomed to the temperature. After a couple of sessions, you can slowly raise the operating temperature of the product for the sweating to be more intense. In case you have a model that features an automatic shut-off timer, set it to shut off after the desired period of time. Just like the temperature settings, it’s best that you take it slow the first couple of sessions to allow your body to get accustomed to this experience. In case the model that you have invested in doesn’t come with an automatic shut-off timer, you will have to do this procedure manually when you want to turn it off.

What Are the Cons of Using It?

You know what are the pros of using an innovative unit like this, but are there any disadvantages at all? The truth is that there are. For example, if it is not being used properly it can cause chafing, acne, or heat rash. These health affections can also appear if you have a very sensitive skin and if you keep using it even if you are not allowed to. Furthermore, there are users who say that it is quite uncomfortable to wear an infrared sauna belt. It also seems to increase the risk of heat-related illness, and the overexposure can cause dehydration. There are voices who say that this belt does not provide long-term results and that it can also cause electrolyte imbalance which may cause cramping. However, you as a user should draw your own conclusion, especially because it is not scientifically proven to be effective.

Common side effects:

Although not very often, sauna slim belts can hide some unpleasant side effects either due to improper use, a malfunction, or incompatibility with your body. Knowing which these side effects are can help you avoid them, so here are the most common ones experienced by users.


The most frequent problem with overexposure to a slim belt is burning your skin. Due to the direct contact with the skin, the sauna belt can get very hot and cause burns. This is why it’s advisable to wear a shirt to protect your skin from the intense heat and never exceed 45 minutes of use. Also, if the sauna shows any signs of damage or tear, stop using it as it could cause shortcuts that can cause severe burns.


The main effect of the sauna belt is sweating and in case you use it for a prolonged time, too much water will come out of your body. To prevent this from happening, drink plenty of water prior and during using the belt. If you feel weakened and dehydrated, stop using the sauna and drink water to restore your body water level.

Increased body temperature

Because of the high temperatures reached by the sauna belt, your body could also become hotter as the core temperature rises. Although it can have great results in relaxing the muscles and accelerating blood circulation, overly increasing your body temperature can also result in heat exhaustion and heat stroke. The best way to prevent such a problem is to avoid using the sauna belt with warm clothes and in high temperatures. Ensure proper ventilation in the room and wear light clothes so you will not feel too hot.

Electrolyte imbalances

Another serious problem that many people ignore is the electrolyte balance of your body that manifests through muscle cramps. In such cases, you must stop using the belt and drink a sports drink that is rich in electrolytes to restore your body’s natural balance.

Skin conditions

The side effects of the sauna belt can also be visible on the outside in skin conditions such as rashes and irritations. While you have the belt on, sweat is held against your skin, keeping fresh air from reaching that area of your body. If you use it for too long, your skin might become sensitive and develop acne or rashes.
