What is the maximum safe temperature for hot tubs to avoid health risks?

The maximum safe temperature for hot tubs is recommended to be not exceeding 100°F. This is primarily due to health risks associated with higher temperatures, particularly for vulnerable populations such as pregnant women, individuals with existing health conditions, or those who are sensitive to heat. At temperatures above 100°F, the risk of overheating and dehydration increases significantly, as well as the potential for heat-related illnesses like heat exhaustion or heat stroke.

Moreover, maintaining the temperature at this level allows for a more comfortable and safer soak, reducing the likelihood of adverse effects on heart rate and blood pressure. While some guidelines suggest a range of 103°F to 105°F might be tolerable for certain individuals, keeping the hot tub at or below 100°F is a precautionary approach that prioritizes safety and overall health.
