In most cases, using a luxury spa hot tub when you have a cold is not a wise choice. While short, low-temperature soaks can provide some relief, if you have a fever, are dehydrated, or are weak, hot water therapy can worsen symptoms and delay recovery.

The luxury massage bathtub relies on jet nozzles and a circulating water system to achieve the massage effect. When the bath liquid produces a lot of foam, the foam can easily enter the nozzle pipes, causing blockages in the air pump or water pump, affecting the normal operation of the device.

The core effects of a luxury spa hot tub come from water temperature, bubbles, jets of water, and hydrostatic pressure. These physical factors have a comprehensive impact on the body, especially stimulating the blood and lymphatic circulatory systems.

Chlorine is currently the most widely used disinfectant, known for its strong bactericidal power and rapid action. Advantages: • Effectively kills bacteria, viruses, and algae; • Economical and readily available; • Continuously released chlorine tablets maintain disinfection effects for a long time.

Impact is a crucial step in ensuring water quality and proper functioning of the luxury spa hot tub. The impact time is generally 10–20 minutes, which can be extended to 30 minutes for larger water volumes or complex systems. Frequency is recommended once a week or after each use, depending on the actual situation.

• If you plan to use your luxury spa hot tub during the winter, ensure it's insulated enough to operate safely in cold temperatures. • If you plan to leave it unused for the entire winter, drain it thoroughly, clean it, and seal it tightly to prevent any residual water from freezing.
