Understanding Sauna Therapy
Heat therapy has been a cornerstone of wellness practices across civilisations, from ancient Greece and Rome to modern-day Finland and Japan. At its core, a sauna is a purpose-built space designed to induce therapeutic sweating. While traditional wisdom has long supported the benefits of sauna bathing, modern science now provides compelling evidence for its numerous health advantages.
Types of Saunas Explained
Today’s sauna landscape offers various options, each with its unique characteristics:
Traditional Saunas
Dry Saunas
Heated using fire, hot stones, gas, or electricity
Characterised by low humidity and high temperatures
Steam Saunas
Generate moisture by adding water to heating elements
Feature high humidity levels
Modern Innovations
Infrared Saunas
Near-infrared: Delivers surface-level heat therapy
Far-infrared (FIR): Provides deeper tissue penetration
Full-spectrum: Combines multiple infrared wavelengths
Hybrid Saunas
Integrate multiple heating methods
Offer versatility in treatment options
The Infrared Difference
Modern infrared technology differs from traditional saunas in several key ways:
Directs heat straight to the body rather than heating the air
Operates at lower temperatures while maintaining effectiveness
Offers varying penetration depths based on wavelength type
The Science Behind Sauna Benefits – Physiological Response
Regular sauna use triggers several beneficial responses in the body:
Increased heart rate (100-150 beats per minute)
