Adding magnesium, such as magnesium sulfate (Epsom salt), to the water in a spa hot tub is only acceptable if the salt content does not exceed the recommended range. Especially when the total salinity exceeds 1500 ppm, it may cause corrosion or damage to the internal components of the hot tub.

In steam mode, a steam shower room primarily consumes water for steam generation: • The amount of water used to generate steam is relatively small, generally about 2-5 liters per hour. • The steam circulates within the enclosed space, preventing immediate water loss, thus reducing water consumption.

1. Preparation • Check water temperature • Check pH level • Wear protective equipment 2. Flushing Operation Steps • Calculate dosage • Dissolve the flushing agent evenly • Start the circulation system • Check residual chlorine or bromine concentration 3. Post-Flush Water Treatment • Maintain circulation • Clean the filter • Check and adjust pH level

Hot Tub Folliculitis (or Hot Tub Dermatitis) is a skin infection syndrome caused by contact with a contaminated hot tub. It is usually caused by a bacterium called "Pseudomonas aeruginosa". When people soak in a poorly maintained or inadequately disinfected hot tub, the bacteria enter the hair follicles or the stratum corneum of the skin.

A spa hot tub consists of multiple systems, and not all systems rely on heating elements. In other words, the term "hot tub" is merely a naming convention, not a limitation. Functionally speaking, a hot tub can also operate in cold water mode.

From a comprehensive medical and health perspective, a tea shower room can indeed provide positive relief in certain illness states, especially for early-stage colds, nasal congestion, muscle aches, and fatigue. However, it is not suitable for use in all "sick" states.
