Saunas have long been used to induce the process of sweating.. They are also therapeutically used to treat bodily conditionsThe normal temperature range for a sauna is 70° to 100° Celsius, or 158° to 212° Fahrenheit.

Dry heat is typically used in traditional Finnish saunas, which typically have a relative humidity of 10 to 20%. The moisture content is higher in other types of saunas. For instance, Turkish-style saunas have higher humidity levels.  

The temperature of the skin can rise to about 40° Celsius (104° Fahrenheit) when using a sauna. Severe perspiration also happens as the skin temperature rises. 

Types of sauna

Wood burning: Sauna rocks and the sauna room are heated by wood. Saunas that burn wood typically have high temperatures and low humidity levels.

Electrically heated: Electrically heated saunas have high temperatures and low humidity, much like wood-burning saunas. The sauna chamber is heated by an electrical heater that is fixed to the floor.

Infrared room: Wood-burning and electrically heated saunas are not the same as far-infrared saunas (FIRS). Certain lamps heat a person's body rather than the entire space by using light waves. Although the temperature is usually lower than in other saunas, perspiration occurs similarly. Infrared saunas typically have a temperature of 60° Celsius.

How does a sauna bath work?

Heat exposure: The sauna room is heated to temperatures typically between 150°F (66°C) and 195°F (90°C). The air humidity is usually low to promote sweating.

Sweating: As the body heats up, it begins to sweat profusely. This sweating helps to eliminate toxins and impurities from the body.

Relaxation: The combination of heat and humidity can promote relaxation and reduce stress.

Benefits of sauna baths

• Improved circulation: The increased blood flow can help improve circulation and overall cardiovascular health.

• Stress reduction: Sauna baths can help reduce stress and anxiety.

• Muscle relaxation: The heat can help relax tense muscles and alleviate pain.

• Skin benefits: Sweating can help cleanse the skin and improve its appearance.

• Weight loss: Sauna baths can help promote weight loss by increasing metabolism and burning calories.

Important considerations

• Hydration: It's crucial to stay hydrated before, during, and after a sauna session. Drink plenty of water to avoid dehydration.

• Duration: The recommended duration of a sauna session varies, but it's typically between 10 and 20 minutes.

• Heart health: People with certain heart conditions or high blood pressure should consult with a doctor before using a sauna.

• Temperature: The sauna temperature should be comfortable for you. If it's too hot, you can take a break or adjust the temperature.
