Humans do not naturally emit significant amounts of electromagnetic waves in the form of radiation. Electromagnetic radiation, such as visible light, infrared, ultraviolet, and so on, is generally emitted by objects with high temperatures or those undergoing certain processes like chemical reactions or nuclear reactions.
However, it's worth noting that all objects with a temperature above absolute zero (-273.15 degrees Celsius or -459.67 degrees Fahrenheit) emit thermal radiation, which includes electromagnetic waves. This type of radiation is known as blackbody radiation. The amount and frequency distribution of radiation emitted by an object depend on its temperature.
In the case of humans, the amount of thermal radiation we emit is relatively small compared to objects at higher temperatures, such as a red-hot piece of metal or a burning flame. The majority of the thermal radiation we emit falls within the infrared range, which is not visible to the human eye.
It's also worth mentioning that human bodies can reflect and absorb electromagnetic waves from the environment, including visible light. That is why we can perceive and interact with the electromagnetic radiation emitted by other sources, such as the Sun or artificial light sources. However, our bodies do not inherently produce significant amounts of radiation on their own.
