Why Does Infrared Feel Hot

It slams into our bodies and sometimes breaks molecules, but very little of it is converted into heat. The heat we feel from sunlight is infrared. So infrared feels hot because we sense it as heat, and because when we feel its heat, there is a lot of radiation, which makes up for its lower energy content.
