Infrared saunas have become one of the fastest-growing wellness trends in recent years. Found in wellness clinics, recovery centres, luxury spas, gyms, and even private homes, infrared saunas are increasingly used for relaxation, recovery, and overall wellbeing.

Unlike traditional saunas that heat the air around you, infrared saunas use infrared light to warm the body directly. This creates a gentler heat experience while still promoting sweating and relaxation.

But what exactly do infrared saunas do, and what are the potential health benefits associated with regular use?

What Is an Infrared Sauna?

An infrared sauna therapy uses infrared heaters that emit infrared light waves designed to penetrate the body and generate heat internally. Traditional saunas typically heat the surrounding air to very high temperatures, while infrared saunas operate at lower temperatures but still encourage deep sweating.

Infrared saunas generally operate between:

  • 40°C and 65°C,
    while traditional saunas may exceed 80°C.

Because of the lower ambient heat, many users find infrared saunas more comfortable for longer sessions.

According to the Simply Oxygen Clinic, infrared saunas use light to create heat that penetrates the skin more directly than conventional heated air.

How Do Infrared Saunas Work?

Infrared heaters emit different wavelengths of infrared light, including:

  • near infrared,
  • mid infrared,
  • and far infrared.

These wavelengths are absorbed by the body, producing heat that may:

  • increase circulation,
  • stimulate sweating,
  • and promote relaxation.

Sessions usually last between 20 and 45 minutes depending on user preference and tolerance.
