Is there a sauna protocol I should follow?

Proper sauna use is important; just like we warm up and cool down our bodies when we exercise, there are some basic steps to follow to ensure you gain maximum benefits of using a sauna. 

Before Sauna Use:

  • Drink a minimum of 8 oz. of water to prepare your body for an increase in core body temperature.
  • Prep your sauna: Pre-heat your sauna for 45-60 minutes. Your sauna will heat up approximately one degree per minute, depending on room temperature. You can use automatic start up for the Signature or Amplify infrared sauna by setting it in Reservation Mode, or schedule a start time or simply use the preheat setting of any program in the mPulse intelligent sauna.
  • Lay down towels on the bench to absorb sweat. It’s also nice to have an extra around to wipe your face during sessions. We recommend using our CELLIANT® towels from our sauna linens collection.

During Sauna Use:

  • Watch your time: Make sure to adjust your session length in accordance to your body’s needs. If you are just beginning with regular sauna use, it is important to start slow and get your body accustomed to infrared therapy. We recommend beginning with 10-15 minute sessions at 100°F every other day. Gradually increase toward 40 minute daily sessions in the optimal temperature range. Always listen to your body and adjust based on what it’s telling you.
  • Stick with it for long-term benefits: Just as with exercise or eating healthy, sauna use takes time and consistency to see results. You may not even sweat the first few times you use your sauna, but know that sweating (and the detox that comes with it) will increase over time, leaving you feeling rejuvenated and healthy.

After Sauna Use:

  • Rehydrate with at least 24 oz. of water or electrolyte drink.
  • Dry off and cool down naturally, or with a refreshing shower.
  • Keep it clean: Using CELLIANT towels on the bench to absorb sweat and excess moisture will help keep your sauna clean during regular use. Clean the wood and glass in your sauna every six months with our Natural Sauna Cleaning Kit.

What health benefits are associated with infrared heat, and which have been proven and documented?

Like nutrition and exercise, infrared saunas are a lifestyle choice that deliver both heat and light, and both provide a wide range of health benefits, which can vary by individual. All of the health benefits Sunlighten saunas may provide have been either clinically shown on our heaters or are based on studies of infrared wavelengths that we precisely mimic in our heaters. Sunlighten saunas are proven up to 99% effective at emitting the highest quality and quantity of infrared heat required for delivery of a number of health benefits.
