Detailed Solution

Every body at all time, at all temperatures $(T > 0)$ emits radiation.

The atoms inside the body keep on vibrating. So, they undergo acceleration. Therefore, the charges present inside it are also accelerated. We know that when a charge is accelerated, then it produces the electromagnetic radiation. Thus, the atomic vibrations result in the emission of the radiations from the bodies. And wavelength of emitted radiation corresponds to the infrared region. So the infrared radiations are emitted by the human body.
