What produces human radiation?

[stochastic]

I know we have to expel energy from our bodies in various ways to maintain homeostasis, but what is producing/generating the radiation to begin with? For example, is it the break down of ATP in cells? I've also heard the heart produces an electromagnetic field, and on that note, how is it that its an electromagnetic field? as in, do we have a changing electric field or a changing magnetic field?

edit: oh sorry i finally got my answer in the physics section, didnt think it was going to happen there. https://www.physicsforums.com/showthread.php?t=177156&page=2

mods feel free it remove this if it suits you.

Heat is by product of all chemical reactions. Our bodies have many chemical reactions happening all the time, hence body heat. The production of ATP is a chemical reaction, so you're right in that sense. Heat also speeds up chemical reactions in the body, hence when you get hot from exercise, you're using more ATP at a faster rate. Got it?

 

[quicknote]

The human body does produce radiation, but it is a very small amount and is not harmful to us or those around us. This radiation is primarily in the form of infrared radiation, which is a type of electromagnetic radiation. It is produced by the metabolic processes that occur within our cells, such as the breakdown of ATP and other molecules. This process releases heat, which is then radiated out as infrared radiation.

In addition, our bodies do produce a weak electromagnetic field, primarily through the activity of our heart and brain. This field is generated by the movement of charged particles, such as ions, within our body. This movement creates a changing electric field, which in turn generates a changing magnetic field. This electromagnetic field is very weak and is not considered harmful to us or those around us.

Overall, the radiation produced by the human body is a natural and necessary part of our biological processes. It is not something that we need to be concerned about in terms of its effects on our health or the environment.
