Contact your Finnish Sauna Builders Specialist today for personalized guidance in selecting the perfect sauna configuration for your space, lifestyle, and wellness goals.
Traditional (Finnish) Saunas: Typically operate between 150°F and 190°F (65--88°C), with a median standard between 165--180°F.
Infrared Saunas: Operate at lower, radiant heat temperatures, generally between 120°F and 150°F.
Beginners: Start with 10 to 15 minutes per session.
Advanced: You can stay longer (up to 20 minutes), but it is best done in "innings". Do a 15-minute session, exit to cool down and rehydrate for 5 minutes, and then return for another round. Always listen to your body and exit immediately if you feel dizzy or nauseous.
This is a matter of personal preference. Traditional saunas use heated rocks where you can add water to create steam and instantly increase the humidity. Infrared saunas are run dry without rocks or steam. You can also add essential oils to your water for aromatherapy.
Before: Yes, shower beforehand to rinse off perfumes, lotions, and oils to keep the sauna sanitary and help your skin sweat freely.
After: Yes, rinse off the sweat, salts, and toxins, and help your pores close back up.
Regular sauna use supports:
Traditional Saunas: Heat the air in the room to high temperatures using electric or wood-burning heaters.
Infrared Saunas: Use invisible light spectrum wavelengths to heat your body directly rather than superheating the surrounding air.
Sauna therapy is generally safe, but you should consult a doctor first if you have underlying cardiovascular conditions, take certain medications, or are pregnant. Never use a sauna if you have a fever, are under the influence of alcohol, or feel lightheaded.
