Discoloration Caused by Excessive Metal Content in the Water This is one of the most common reasons for water yellowing in whirlpool spa hot tubs. • Iron (Fe) • Manganese (Mn) These metals typically originate from: • Tap water pipes • Well water • Untreated water sources used for refilling

Saunas are typically experienced at higher temperatures, resulting in a more pronounced increase in heart rate and a more direct stimulus to the cardiovascular system. In contrast, the water temperature in a spa hot tub is generally more controllable, leading to a milder and more gradual cardiovascular response.

Spa hot tubs are typically set to temperatures between 37°C and 40°C (98°F and 104°F). While this temperature range is comfortable and relaxing for non-pregnant adults, it may pose risks to pregnant women. Consequently, the medical consensus is that one should avoid prolonged immersion in high-temperature spa hot tubs while pregnant.
