In most cases, this is perfectly normal. A swim spa tub is essentially an open water system, especially when installed outdoors, where the water surface is directly exposed to the air. As long as the water surface is exposed, evaporation is inevitable.

Yes, a swim spa tub can absolutely function as a hot tub. A swim spa tub is an integrated spa device that typically possesses the following core features: • Large water volume • Constant temperature heating system • Powerful water flow system • Water circulation and filtration system etc.

Based on existing research, sauna therapy may help lower low-density lipoprotein cholesterol (LDL-C) and triglycerides (TG), and increase high-density lipoprotein cholesterol (HDL-C). This change has positive implications for the prevention of dyslipidemia and cardiovascular disease.

Swim spa hot tubs are typically maintained at a temperature of 33°C to 38°C. Warm water initially dilates blood vessels, followed by slight vasoconstriction as the body regulates temperature. This temperature cycle makes the nervous system more active, thus triggering a "wrinkle response."

The bactericidal effect of chlorine decreases significantly at pH > 7.8, while bromine remains effective within the pH range of 8.0–8.5. This means that users do not need to frequently adjust the water quality in a spa hot tub.

Studies show that adults can lose 0.8 to 1.5 liters of water per hour during light activity in hot and humid environments. Even if the use of a steam shower room typically does not exceed 30 minutes, it can still result in a loss of approximately 0.5 to 1 liter of body fluids, exceeding the range that normal drinking water can automatically regulate.
