Far Infrared Radiation (FIR) (λ = 3–100 μm) is a branch of the electromagnetic spectrum, and many professionals have conducted experiments and research into its biological effects. In this article, we will explore the medical benefits of FIR radiation, as well as the effectiveness of gemstone heat therapy mats.
1. Introduction
All living organisms are affected by natural electromagnetic radiation from the Sun that reaches Earth. This radiation impacts life at all levels, from subcellular organelles to the entire body. Heat radiation (or infrared radiation) is a part of the full electromagnetic spectrum and has been effectively used for treating and relieving various ailments for thousands of years.
1.1 What is Far Infrared Radiation?
Compared to the full electromagnetic spectrum, infrared (IR) radiation covers a wavelength range of 750 nm to 100 μm, a frequency range of 400 THz to 3 THz, and photon energy from 12.4 meV to 1.7 eV. The International Commission on Illumination (CIE) divides infrared radiation into three subcategories.
In the infrared radiation range, only far infrared (FIR) transmits energy purely in the form of heat. The thermoreceptors in human skin can perceive this as radiant heat, which is absorbed by the body.
2. Medical Applications of Far Infrared Radiation
Far infrared radiation is widely recognized for its therapeutic properties. Although its wavelength is too long to be visible to the human eye, the body converts this energy into gentle radiant heat, which can penetrate up to 1.5 inches (about 4 cm) below the skin. When the skin is exposed to FIR, the resulting surface temperature is higher than that produced by shorter wavelength forms of heat.
2.1 FIR-Emitting Ceramics
Ceramics that emit FIR have been known for years. All ceramics emit infrared radiation based on their temperature. During the gaslight era, ceramic lampshades were heated by gas flames and emitted both infrared and visible radiation. The exact chemical composition of the ceramic material determines the relationship between temperature and infrared emission.
Tourmaline, a boron-silicate mineral (also known as a gemstone in its crystalline form), emits FIR when ground into fine powders. The characteristics of FIR emission depend on the particle size.

Far Infrared Saunas / Heating Mats: Compared to traditional saunas, FIR heating cabins heat the skin more quickly, but higher levels of skin irradiation are needed to induce noticeable sweating. These cabins are popular in Japan and are referred to as "Waon Therapy." A more convenient alternative to large saunas is the FIR heating mat. People can lie on the mat for therapy, and it is easy to store away when not in use, making it space-efficient and flexible.
FIR therapy has been widely used to treat cardiovascular diseases, particularly chronic heart failure and peripheral artery disease. FIR saunas have been shown to improve heart and vascular function while reducing oxidative stress in chronic heart failure patients. A study on patients with rheumatoid arthritis and ankylosing spondylitis indicated that infrared sauna therapy helped relieve pain, stiffness, and fatigue.

FIR-Emitting Ceramics: FIR-emitting ceramic discs and garments have been applied to the human body for various benefits, including improving sleep quality, aiding lactating women with breast milk production, and treating conditions like arthritis and Raynaud’s disease.
3. Gemstone Heating Mats and Their Healing Benefits
Some modern infrared heating mats combine FIR-emitting ceramics, such as tourmaline, with gemstones, allowing people to enjoy the healing benefits of FIR therapy from the comfort of their home. These gemstone mats are gaining popularity because of the unique properties of the gemstones used, such as amethyst, jade, and others, which not only emit FIR but also have specific effects on the body, mind, and spirit.
Acada Tourmaline Ceramic Infrared Heating Mat
- Gemstone: The mat is entirely filled with tourmaline ceramic, enhancing its ability to emit FIR.
- Price: $229.99, which is considered one of the most affordable options in the market. The brand designs, develops, and manufactures its products, operating as a direct-to-consumer (D2C) business. By cutting out middlemen, they offer high-quality products at competitive prices, ensuring that more people can benefit from FIR therapy.

Reviews: While the mat doesn’t have an overwhelming number of reviews, the ones it has are authentic and come from verified customers. Here's a recent review:
“I bought this heat mat not long ago. When I received the package, the invoice was not inside. After contacting the seller, they emailed it to me quickly. The heat mat came with a liner, which I believe helps trap the heat in and keep the mat clean. I keep it on my sofa and lie down every day to ease my lower back pain. The temperature rises quickly and stays consistent. The whole mat stays warm evenly. I love it!”

4. Other Gemstones Used in FIR Mats
Besides tourmaline, other gemstones such as amethyst and jade have also been shown to emit FIR. These crystals not only have the ability to radiate infrared heat but also offer distinct physical, psychological, and spiritual benefits due to their unique properties. These qualities make gemstone heating mats highly popular among consumers seeking a more holistic approach to healing.
