What best describes the temperature range for a hot tub or spa environment?

The temperature range of 100°F to 104°F is best for a hot tub or spa environment because it aligns with the recommendations of health and safety organizations regarding safe soaking temperatures. This range provides a balance of comfort and therapeutic benefits, allowing users to enjoy relaxation and potential muscle relief without the risks associated with higher temperatures.

At temperatures lower than this range, such as 90°F to 100°F, the water may feel too cool for many users who seek the soothing heat typically associated with hot tubs. Likewise, temperatures approaching or exceeding 105°F can pose health risks, including overheating and dehydration. Therefore, maintaining the water temperature within the 100°F to 104°F range is essential to ensure a safe and enjoyable experience while maximizing the benefits of the hot tub or spa environment.
