We all have different choices when it comes to setting up temperatures for a bath. The same goes for setting up the temperature of the water in the hot tub. While some do not like the temperature less than 38 degrees celsius. Some are comfortable with more than 40 degrees celsius.

Your preference is entirely usual, but you should keep in mind that the hotter the temperature, the less time you should spend inside it.

2. Health Condition

It can cause the risk of drowning and also contains certain substances which can be harmful to babies.

For adults, if you are staying in a hot tub, make sure you are constantly hydrated and do not stay more than 30 minutes in one sitting or session. And after a session, if you want, you can have a shower to balance your temperature.

Changing your seat to a higher level where your torso is above the water line lets you cool down.
