Using & care
Simple to use, easy to keep
Your session
- Traditional Finnish heat is typically enjoyed around 160–195°F
- Ladle water onto the stones for soft bursts of steam
- Sit higher for more heat, lower for less
Stay comfortable
- Drink water before, during and after
- Sit on a towel and keep one on the floor
- Cool down slowly between rounds, or pair with a cold plunge
Care
- Wipe benches with plain water and a soft cloth
- Leave the door ajar after use so the wood can dry
- Avoid chemical cleaners on the wood
Drink water before, during and after. If you have a heart condition, low or high blood pressure, are pregnant, take medication or have another medical condition, check with your clinician before using a sauna. Never use a sauna after alcohol, and leave right away if you feel dizzy or unwell.
Research
What regular sauna use may support
Heart health over time
In a long-term Finnish study, people who used a sauna 4 to 7 times a week had lower rates of heart-related death than those who went once a week. Read the study
Healthy blood pressure
Adding a short sauna after exercise lowered blood pressure more than exercise alone. Read the study
Stroke risk
In a 15-year study of Finnish men and women, frequent sauna users had a lower rate of stroke than people who went once a week. Read the study
Memory with age
In a 20-year study of Finnish men, those who used a sauna 4 to 7 times a week had lower rates of dementia. Read the study
Tension relief
Regular sauna sessions reduced the intensity of tension-type headaches in adults who had them often. Read the study
The bigger picture
A review of sauna research summarizes what is known about regular sauna bathing and health. Read the review
These studies looked at traditional Finnish saunas, mostly in Finnish adults, as part of a healthy lifestyle. They show links, not guarantees, and a sauna complements care from your healthcare team rather than replacing it.
