Steam shower bathrooms, by creating a warm, high-humidity environment, affect the skin and facial tissues through the action of steam, having a certain impact on facial swelling, mainly in terms of blood circulation, lymphatic drainage, and water regulation.

A steam sauna shower room is a multi-functional bathroom device that integrates steam sauna and shower functions. It not only provides the high-temperature, humid environment of a traditional sauna but also allows for shower cleaning and hot/cold water alternation, enabling users to complete the entire sauna and shower experience in the same space.

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.
