It's time to clear up the doubts
Sauna use is not merely a relaxing pastime – it’s a conscious form of wellness with proven health benefits. It improves circulation, supports detoxification, reduces stress, and strengthens the immune system. Yet, despite decades of scientific evidence, many people still avoid saunas due to common misconceptions or misinformation. Below, we explore three widespread myths to clarify the real effects of sauna use.
This is one of the most frequent misunderstandings used to downplay the benefits of sauna bathing. While it is true that the body loses fluids through sweat, this is not the whole story. In a traditional sauna, the sweat consists primarily of water. However, in an infrared sauna, the deeper heat penetration significantly increases the amount of toxins released through perspiration.
Research shows that up to 20% of sweat produced in an infrared sauna can contain toxins, heavy metals, and environmental pollutants the rest is water. This deep-tissue heat helps to cleanse the body on a cellular level and removes harmful substances that accumulate in the subcutaneous layers.
Many people believe sauna use is only safe for those in top physical condition. This is not entirely true. While it’s essential to consult a doctor if you have certain medical conditions, there are many types of saunas that are suitable and even beneficial for people with health issues such as heart conditions, prosthetics, or implants.
The bio sauna, for example, is a gentler option that operates at lower temperatures (around 45–60°C) with higher humidity. It provides a pleasant yet effective form of relaxation, even for those who may find traditional Finnish saunas too intense. The moderate heat may also trigger a mild artificial fever response, which stimulates the immune system, supports the body’s self-healing processes, and may help alleviate respiratory symptoms.
This claim is only partially true. Yes, sauna use primarily causes fluid loss, but with regular and extended use, it also boosts metabolism and promotes calorie burning. In an infrared sauna, the body can burn up to 300 kilocalories per hour comparable to moderate physical exercise, especially when the sweating is deep and prolonged.
Additionally, heat exposure enhances blood circulation, improves lymphatic flow, and accelerates metabolism. These effects support long-term body composition improvement and the elimination of waste materials. While saunas do not replace exercise or a healthy diet, they are an excellent complement to a wellness-focused lifestyle.
