What is the Ideal Temperature for a Hot Tub?

Public hot tubs and private spas should strictly follow the regulations regarding the hot tub temperatures prescribed by the United States Consumer Product Safety Commission (CPSC).

For everyone's safety, the temperature should not exceed 40 degrees Celsius (104 degrees Fahrenheit). The Commission extracts strict penalties on those who do not abide by this standard. This limit has been imposed in order to prevent hot tub related accidents, including drowning, scalding, dehydration and motor malfunction. However, the temperatures slightly vary according to the general climate of the location.

Why high temperatures are risky

In 2005, there were reportedly hundreds of accidents involving hot water tubs. Many of these cases were due to excessive water temperatures. It has been found out that bathing in very warm waters induce drowsiness, and if you fall asleep in the hot tub, there is a great possibility for you to slide down and drown. Moreover, if you are taking a dip in the hot tub after a hard day at the gym, then the hot tub can raise your body temperature to extremely critical levels, which may cause a lot of problems.

What safety precautions can you take?

To play safe, never exceed the maximum prescribed temperature for hot tub water. In addition, do not enter a hot tub immediately after coming home from an especially strenuous workout. Take some time to cool down for a while before bathing. Make sure you drink plenty of fluids before, during and after a hot tub session to replace the water you have lost in the form of sweat.

Other health-related risks aggravated by very hot tub water are lightheadedness, extreme weakness, nausea and dehydration. Pregnant women should be very cautious when bathing in hot tubs.
