Furthermore, submerging your head in the water can cause suffocation, burns, ear damage, or microbial infection. Children and the elderly are particularly at risk and must be strictly supervised.

Human circadian sleep rhythms are closely linked to changes in body temperature. Body temperature typically drops gradually during the night, signaling to the brain that it's time to rest. However, soaking in a whirlpool spa hot tub increases your body's surface temperature, causing your capillaries to dilate. Afterward, your body temperature drops rapidly.

Based on existing research and experimental data, static soaking in a spa hot tub for 30 minutes can burn approximately 80 to 130 calories. This is influenced by factors such as: · Water temperature; · User body type and metabolic rate; · Duration of soaking; · Whether or not light exercise is combined with soaking.

Based on the above analysis, whether an outdoor spa hot tub is a luxury item really depends on one's perspective: • From the perspective of price and non-essential attributes, it has a luxury element. • From the perspective of health, relaxation, and functionality, it's more of a high-end lifestyle amenity.
