Sure! When the body is immersed in hot water at 38-40℃, the blood vessels in the skin naturally dilate due to the heat. The blood vessels enlarge, increasing blood flow and delivering more heat to the limbs, gradually relieving the feeling of coldness.

Clogged masssage jets not only affect the user experience but can also cause the following problems: 1. Reduced water flow and decreased massage effect 2. Increased load on the heating system 3. Increased risk of bacterial growth 4. Increased noise

Thermal therapy studies have shown that immersion in water around 40°C for 15 to 30 minutes can increase skin blood flow by 30% to 50%. Combining a spa hot tub with jet massage can enhance local muscle blood flow and accelerate the excretion of metabolic waste.

Chlorine is suitable for users with limited budgets who value rapid disinfection, but it is not the best choice for those sensitive to odors and skin irritation. Bromine is ideal for users who use whirlpools, spas, and hot tubs frequently and prioritize comfort and water quality stability.

Professionals recommend that pregnant women keep the water temperature between 36°C and 37.5°C when using a whirlpool spa hot tub. This temperature ensures a comfortable spa experience without causing hyperthermia.
