Outdoor - specific square sauna room, equipped with an electric furnace. It is suitable for post - exercise recovery and for the elderly. It is a full - spectrum sauna room.

### Space Design The square structure is regular, which can effectively utilize the space and adapt to various outdoor environments. The interior space is spacious, and multiple rows of seats can be set up according to needs. It can accommodate multiple people using simultaneously, making it suitable for both family use and sharing with friends. ### Heating Method It is equipped with an electric furnace, which provides stable and efficient heating. The electric furnace has a precise temperature control system, allowing the temperature to be adjusted as required. Meanwhile, the full - spectrum far - infrared technology can emit light with a wavelength similar to that of the human body's own far - infrared rays. These rays can penetrate deep into the subcutaneous tissue of the human body, promote blood circulation, accelerate metabolism, help break down lactic acid after exercise, relieve muscle fatigue and soreness, and assist the body in recovering quickly. ### Material Selection High - quality woods such as red cedar and hemlock are usually selected. These woods are naturally anti - decay and insect - resistant, can adapt to outdoor environments, and have good heat - insulation performance, which can reduce energy consumption. The woods can also emit a natural aroma, creating a comfortable and relaxing atmosphere. ### Safety and Comfort For the elderly, the electric furnace heating has no open flame, ensuring high safety. The temperature in the full - spectrum sauna room is relatively mild. Unlike traditional saunas with high temperature and high humidity, it places less burden on the heart and has a more gentle impact on blood pressure. Ergonomic seats can be set up inside to provide comfortable support, making it less likely to cause fatigue even after sitting for a long time. At the same time, ventilation openings can be equipped to keep the air circulating and avoid stuffiness. Thoughtful small designs such as storage racks can also be added to facilitate the placement of items. ### Temperature and Humidity Control The temperature can be controlled within an appropriate range. Generally, the medium - low temperature environment is between 40 - 60°C, and the humidity is maintained at about 30% - 40%. This environment makes the elderly feel more comfortable and is also suitable for the relaxation and recovery of the body after exercise. It can make the human body produce fine, uniform, and deep sweating, excreting harmful substances.
