FAQ
Does the sauna suit work?
The training suit helps you sweat more during exercise. When you wear the suit, your body sweats more because it's covered in insulation. This causes you to lose water weight and can lead to weight loss.
You can also refer to the description of sauna suits in WEBMD literature - What Is a Sauna Suit?
Is a sauna suit good for weight loss?
Yes, it is a good option for weight loss. It can help you burn more calories, and it can also help to sweat out toxins. However, it's important to use it safely, and you should always consult with your doctor before using it. So, buy a sauna suit today and experience the difference!
[Another study compared fitness results between groups of participants, some of whom wore sauna suits to exercise and some of whom did not. Both groups engaged in similar exercise routines. At the end of the study, the group that wore the sauna suits showed an 11.7%improvement in VO2 max, or the amount of oxygen their body used when exercising as hard as possible, compared to a 7.3% improvement in the exercise-only group. The sauna suit group also had an average 2.6% reduction in body weight and 13.8% decrease in body fat. The exercise-only group averaged a 0.9% reduction in body weight and an 8.3% decrease in body fat.] Literature source: WEBMD
What to Wear under a sauna suit?
Traditional sauna suit and HOTSUIT 904 classicdo not have a sweat-absorbing function, which will cause sweat and fabric to stick to the skin, causing discomfort. We recommend wearing a HOTSUIT sweat-absorbing shirt
It is worth mentioning that HOTSUIT has broken through this problem and broken the discomfort of wearing traditional sweat-inducing clothing. HOTSUIT 904 PRO/MAX both have sweat-absorbing and breathable functions, allowing you to train without burden.
How long should we wear a sauna suit?
Some people recommend wearing a slimming suit for as little as 10 minutes, while others recommend wearing it for up to an hour. It all depends on your own personal tolerance and what you are hoping to achieve by wearing it.
If you are looking to lose weight, you will likely see better results if you wear the suit for a longer duration (up to 60 minutes). However, if you are just looking for general health and fitness benefits, then 10-15 minutes should be sufficient.
