Infrared itself is a kind of radiation, and everything in the world, including the human body, emits infrared radiation all the time. The earth itself has radiation, which is called background radiation.

Electromagnetic radiation is radio waves, microwaves, infrared rays, visible light (which can be subdivided into red, orange, yellow, green, blue and purple according to frequency bands), ultraviolet rays, X-rays and gamma rays. Only gamma rays, X-rays and high-dose and high-intensity ultraviolet rays are harmful to human body. (Far infrared ray is the electromagnetic radiation section in the infrared band that is far away from the red light ratio and relatively close to the microwave band. )

So back to the topic, which far-infrared foot bath bucket must have radiation, but it is harmless.

The same is true of other electrical appliances in daily life, such as mobile phones, televisions, microwave ovens and so on. I hope the landlord will not be misled by radiation rumors again.

PS: The World Health Organization, the State Science and Technology Commission, CCTV and many other scientific and technological media have refuted such radiation rumors.
