Explanation
As stated above, infra-red radiation belongs to the category of electromagnetic radiation where its wavelengths are longer than visible light and shorter than radio waves. Although we are not usually able to see infra-red radiation, we can certainly feel its effects. One common feeling when infra-red radiation comes into contact with our skin is warmth or heat. Thus, we feel warm (or hot) when infra-red radiation strikes our skin, which correlates with scenarios such as standing near a radiating heat source or under sunlight. So, the most appropriate word to fit in the sentence "if infra-red radiation hits the skin, you feel ___" would be "warmth".
