A human body has a surface area of approximately . The normal body temperature is above the surrounding room temperature $
1
The amount of energy radiated by the body in second is close to Joules
2
If the surrounding temperature reduces by a small amount $\Delta\,<
3
Reducing the exposed surface area of the body (e.g. by curling up) allows humans to maintain the same body temperature while reducing the energy lost by radiation
4
If the body temperature rises significantly then the peak in the spectrum of electromagnetic radiation emitted by the body would shift to longer wavelengths
