Based on medical advice and the physical characteristics of the elderly, it is generally not recommended for people over 70 years old to stay in a steam sauna room for more than 10–15 minutes.

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.

Sweating Promotes Reduced Antidiuretic Hormone (ADH) Secretion However, in the high temperature and humidity environment of a steam sauna, increased body temperature and external stimuli temporarily inhibit ADH secretion.

A home steam sauna room possesses four physical characteristics: "medium-high temperature + high humidity + saturated steam + a sealed environment," posing a clear challenge to any electronic device without a professional protection rating.

A steam sauna room uses a steam generator to heat water, producing large amounts of moist, hot steam. This raises the humidity to over 80%, and the temperature is generally maintained between 40°C and 50°C. These characteristics have certain impacts on clothing. For example, high humidity makes cotton fabrics, which absorb moisture, unsuitable, and confined spaces require minimal clothing.

Water sprinklers are generally not necessary in steam sauna rooms for the following reasons: 1. The room is already saturated with water, so no additional water is needed; 2. The space is enclosed, and water sprinklers may cause water accumulation; 3. Water sprinklers increase the installation and maintenance burden; 4. Most usage needs can be met through the control of steam equipment.
