We are warm enough to emit infrared rays.
Hot things give off infrared radiation, which is a form of electromagnetic radiation that lies within the infrared region of the electromagnetic spectrum. This type of radiation is invisible to the human eye but can be felt as heat on the skin.
Microwaves emit electromagnetic radiation in the form of microwaves when they are turned on. This radiation is absorbed by food and causes water molecules in the food to vibrate, generating heat that cooks the food.
Radiation is energy transfer by electromagnetic waves.
Dark Matter
A 'ray' is a term for a radiation. All objects with temperatures above 0 degrees Kelvin give off radiation called, "Heat".

Examples of electromagnetic radiation include radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays. Visible light is a specific range of electromagnetic radiation that our eyes can detect, falling between ultraviolet and infrared light on the electromagnetic spectrum.

Nuclear fusion within the Sun causes it to give off infared radiation and electromagnetic radiation.
The sun gives off a variety of electromagnetic waves, including visible light, ultraviolet radiation, and infrared radiation. This electromagnetic radiation is essential for sustaining life on Earth and driving various processes in the atmosphere.
The phone gives of low level electromagnetic radiation whenever it is on. It uses electromagnetic waves to connect to the phone mast to send/receive calls. Your phone ringing had no effect at all on the levels of electromagnetic radiation. Anyway, your phones electromagnetic radiation DOES NOT HARM YOU. If that's what your thinking, many investigations have shown NO HARMFUL EFFECTS of using phones.
"Radio" is the generic name we give to electromagnetic radiation with frequencies less than 300 GHz (wavelengths greater than 1 millimeter).
