Prepare for your sauna session
Drink water. Make sure you’re hydrated before going into an infrared sauna. Drink a glass of water before your session. You can also bring water into the sauna, especially if you’re sensitive to higher heats.
Choose the temperature. The average temperature for an infrared sauna ranges from 100˚F to 150˚F, with beginners starting out at the lower end and more experienced users at the higher end. If this is your first time, start with 100˚F. You may want to stay at this temperature for a few sessions. You can always increase the temperature each session until you reach 150˚F.
Length of time. For first-time users, start with 10 to 15 minutes. You can add time each session until you reach the suggested time of 20 to 30 minutes. Saunas come with a timer, so make sure to set it. You don’t want to stay in there too long and risk becoming dehydrated.
Clothing. How you dress is your choice. Some people will wear bathing suits, while others prefer to go in naked.
What you can do while in the sauna. Relax, read, meditate, listen to music, or visit with friends. Just don’t go to sleep.
After the session is over. When your session is done, it’s suggested that you take your time and let your body cool down. Once cooled down, feel free to take a shower or bath. Just make sure you are drinking plenty of water.
Number of sessions per week. Most facilities that offer infrared sauna treatments recommend using the sauna three to four days per week. If you are healthy and tolerate the four days, you can use the sauna daily.
