A Brief History Of Infrared Saunas

Infrared saunas represent a major chapter in the history of wellness and technology. Emerging from the discovery of infrared radiation in the late 19th century, the infrared sauna has materialized through a blend of scientific research and technological creativity.

This article traces their journey from the initial observations by Sir William Herschel to the sophisticated health promoting tools they are today, highlighting key developments and contributions that have shaped their current form. 

The Advent of Infrared: Sir William Herschel's study (Late 1800s)

The journey of infrared saunas begins when Sir William Herschel chanced upon infrared radiation in 1800. Herschel, an astronomer by profession, conducted an experiment using a prism and a thermometer, leading to the identification of a type of heat invisible to the naked eye.

This groundbreaking find opened new avenues in the study of the electromagnetic spectrum and laid the foundation for future progress in heat-based therapy. Herschel's work is detailed in this comprehensive piece on space.com [1]. 

John Harvey Kellogg’s Radiant Heat Bath (Early 20th Century)

Transitioning from Herschel's work, the early 20th century saw John Harvey Kellogg, a prominent physician and health-food pioneer, invent the Radiant Heat Bath. Using incandescent light bulbs to generate infrared heat, Kellogg revolutionized the concept of saunas.

This form of heat therapy differed significantly from traditional steam-based saunas, offering deeper tissue penetration and more pronounced health benefits. Kellogg's more wacky inventions in health treatments are further explored at the History Channel's website [2]. 

Nowadays, infrared saunas are available in the most beautiful designs

Far Infrared Technology: Dr. Tadashi Ishikawa in Japan (1960s)

In the 1960s, Dr. Tadashi Ishikawa of Japan patented a far infrared heater, marking a make-shift evolution in sauna technology. Far infrared rays are known for their ability to penetrate deeply into the body, offering enhanced therapeutic benefits.

Initially reserved for medical applications, this technology eventually permeated into mainstream wellness activities, allowing a broader audience to experience its benefits. The specifics of far infrared technology and its health implications are discussed in detail on Healthline [3].  

NASA’s Contributions: Advancements in Infrared Technology (1970s)

NASA’s research in the 1970s propelled the development of infrared saunas to new heights. Their studies in infrared technology for space applications led to notable improvements in sauna heating elements, energy efficiency, and safety features.

This research not only optimized the functionality of infrared saunas but also made them more accessible to the public. NASA's role in upgrading infrared technology is showcased on their official website, detailing various infrared technology applications [4].

Sauna blankets are the most accessible and affordable type of home infrared sauna

The Modern Era of Infrared Saunas

Today, infrared saunas are at the forefront of lifestyle technology, blending history, science, and relaxation. Modern saunas boast sophisticated design and materials, precise temperature controls, and additional tech features like Bluetooth connectivity and chromotherapy. Achievements that cater to a growing demand for personalized and holistic health experiences. 

The latest and very popular additions to the sauna family, are the infrared sauna blanket and the PEMF mat. These wonders of technology are home infrared sauna solutions that bring you all the benefits, and that can be folded, stored in a closet, or carried with you wherever you go.

As the realm of infrared saunas continues to expand with cutting-edge technology, and spearhead treatments that elevate general wellbeing, following current and future developments is useful if you're a sauna enthusiast and health-conscious.
