Why can bamboo charcoal release far infrared rays?

Among the infrared rays, there is an infrared ray with a wavelength of 4 ~ 14 micron, which is especially called far infrared ray. Because it has the same wavelength as the organism itself, it is also called [nurturing light]. Bamboo charcoal can play the role of far infrared rays after being fired at a high temperature above 700 degrees Celsius. Far infrared rays can warm the body and promote peripheral blood circulation, so they have health care effects. Mattresses, cushions, kneepads, waist protectors and other products filled with bamboo charcoal particles.

Bamboo charcoal is a kind of charcoal, which is made of three-year-old alpine bamboo and fired at nearly a thousand degrees. Bamboo charcoal has loose and porous structure, fine and porous molecules and hard texture. Strong adsorption capacity, can purify the air, eliminate odor, absorb moisture, prevent mildew, inhibit bacteria and repel insects. Contact with human body can eliminate dampness and absorb sweat, promote blood circulation and metabolism, and relieve fatigue. After scientific refining and processing, it has been widely used in daily life.

Infrared is an electromagnetic wave with a wavelength between microwave and visible light, with a wavelength between 760 nanometers (nm) and 1 mm, which is longer than red light.

Anything above absolute zero (-273. 15℃) can produce infrared rays. Modern physics calls it thermal rays. Medical infrared rays can be divided into near infrared rays and far infrared rays. It contains heat energy, and the heat of the sun is mainly transmitted to the earth through infrared rays.
