far-infrared raises core body temperature by approximately 2°C

hyperthermia well-supported
Increased nuclear body temperature by approximately 2°C

What this means for you

Induces therapeutic fever response and immune activation

The published research

Title not yet captured
The full text explicitly states that 'heat and humidity of ozone steam bath increase the nuclear body temperature by 2 °C on an average due to cessation of heat output (hyperthermia),' directly matching the response statement. It further documents downstream effects including perspiration, increased metabolism, and functional stimulation consistent with a therapeutic hyperthermia response.
