Infra-red radiation.
Infrared radiation is commonly felt as heat. This type of radiation is responsible for the warmth felt from sunlight, fire, or heated objects.
Infrared radiation is the type of radiation that is sometimes felt as heat. It is part of the electromagnetic spectrum and is produced by the vibration and movement of molecules.
No, ultraviolet (UV) radiation cannot be felt as heat because it is not a form of thermal (heat) energy. UV radiation is part of the electromagnetic spectrum and interacts with the skin differently from thermal energy. While UV radiation can cause sunburn and damage to skin cells, it does not produce a sensation of heat like infrared radiation.

Infrared radiation.
Any form of radiation can produce heat. Infra-red radiation is the most commonly recognized as heat, but the question has a much longer answer if you need to know the why.
A heat lamp typically emits infrared radiation, which is a type of electromagnetic radiation that is invisible to the human eye. Infrared radiation is what produces the heat felt when using a heat lamp.
Electromagnetic
Invisible heat radiated from objects is in the form of infrared radiation. This type of radiation is not visible to the human eye but can be felt as heat when it strikes the skin.
Thermal radiation, in the infra red part of the spectrum. Microwave radiation also causes heat but that acts in a different way, by agitating the molecules in the water content of the food you are cooking.
Infrared radiation is the electromagnetic radiation that is felt as heat. It has longer wavelengths than visible light and is emitted by all objects with a temperature above absolute zero. Infrared radiation is commonly used in applications such as thermal imaging and remote temperature sensing.
Infrared radiation is emitted by the human skin. This type of radiation is invisible to the human eye but can be felt as heat.
