All organic and inorganic bodies emit infrared (IR) energy, even bodies colder than ambient temperature. Therefore, if our eyes were sensitive to infrared wavelengths, we could see in the dark. We can live with this limitation because other forms of light are visible, and because heat manifests itself to us, though not always obviously. We learn, for instance, that a glowing ember is very hot and a frozen lake isn't, though we don't know the precise temperature of either, and human vision is of limited use in interpreting temperatures between such extremes. For that, we may rely on our sense of touch, but only when direct contact or a very short distance is involved.
