Origin of IR radiation in living things ?

In summary, IR radiation in living things is produced through cellular processes and is essential for regulating body temperature, aiding in metabolic processes, and promoting growth and development. While small amounts are beneficial, prolonged exposure to high levels can be harmful. However, there are also benefits such as the production of vitamin D and medical treatments using infrared therapy.

Hi,

I've been reading that in a relatively normal environment about 1/2 of human heat loss is due to radiation. Most of this seems to have a wavelength of 10-12 μm.

Could someone here speak to the molecular origin of this? I'm guessing it is mostly from water molecules going from a higher to lower energy state, but can't find any information on the specifics.

thanks in advance,

Some transitions in molecules are involved, but don't forget blackbody radiation - the emitted photons have an energy which corresponds to typical kinetic energies of the moving molecules.
 

1. What is the origin of IR radiation in living things?

The origin of IR radiation in living things can be traced back to cellular processes and biochemical reactions. This type of radiation is a byproduct of metabolism and the conversion of energy from food into usable forms.

2. How do living things produce IR radiation?

Living things produce IR radiation through the absorption of energy from food and the subsequent generation of heat as a result of metabolic processes. This heat is then emitted as IR radiation.

3. Is IR radiation essential for living things?

Yes, IR radiation is essential for living things. It helps regulate body temperature, aids in metabolic processes, and even plays a role in the growth and development of certain organisms.

4. Can IR radiation be harmful to living things?

In small amounts, IR radiation is not harmful to living things. However, prolonged exposure to high levels of IR radiation can lead to tissue damage and other health issues such as skin burns and eye damage.

5. Are there any benefits of IR radiation for living things?

Yes, there are several benefits of IR radiation for living things. It helps maintain body temperature, aids in the production of vitamin D, and can even be used in medical treatments such as infrared therapy for pain relief and wound healing.
