In high-end spa jacuzzi bathtubs, the two are often used in combination to create a dual hydrotherapy experience: first, bubbles soothe the nerves, then water flow deeply relaxes the muscles, achieving balanced relaxation throughout the body.

Most spa hot tubs are equipped with electric heaters or heat pumps, using a temperature sensor to monitor the water temperature in real time. When the water temperature drops below the set value, the system automatically heats up; once the target temperature is reached, heating stops to maintain a stable temperature.

For patients with heart disease, high blood pressure, or low blood pressure, the use of a hydrotherapy spa tub requires special caution. The temperature of a hydrotherapy spa tub is usually between 36°C and 40°C. Soaking in hot water can cause vasodilation, leading to fluctuations in blood pressure.

The temperature of a whirlpool spa hot tub is usually slightly higher than body temperature. The heat stimulates the dilation of capillaries, accelerating blood flow. The heat also increases the metabolic rate of epidermal cells, making it easier for dead skin cells to shed, resulting in a smoother new cell layer.

General Recommendation: Flush the swim spa hot tub after every 3 to 5 uses, or at least once a week. This achieves a good balance between maintaining water quality and maintenance costs.

Using excessively high concentrations of hydrogen peroxide in swim spa hot tubs may corrode or irritate bath equipment, pipes, and human skin. Therefore, the concentration must be strictly controlled during disinfection; a low concentration (1%~5%) added in stages is generally recommended.
