Temperatures vary by type. Traditional Finnish saunas require at least 65 degrees Celsius and infrared saunas range between 49-60 degrees Celsius. 

Choosing Between a Hot Tub and a Sauna 

When deciding between a hot tub and a sauna, consider your specific health goals and personal preferences. If you suffer from muscle or joint pain, a hot tub might be more beneficial due to the buoyancy and warmth of the water, which can alleviate pressure on joints and improve circulation. Additionally, hot tubs are excellent for socialising, making them a great choice if you enjoy relaxing with friends or family. 

On the other hand, if cardiovascular health and overall stress reduction are your primary concerns, a sauna may be more suitable. The high heat and sweating in a sauna can mimic the effects of moderate exercise, improving heart health and promoting relaxation. Saunas also offer the added benefit of potentially enhancing respiratory health and reducing the risk of chronic diseases.
