Infrared heat comes from the projection of a certain wavelength of light, which behaves in the same manner as sunlight. Infrared radiation, also known as “radiant heat,” can pass through the vacuum of space and our atmosphere without being disturbed. Short- and medium-wave infrared outdoor heaters provide warmth the exact same way — by emitting warmth that affects only physical objects in its path and not nearby air. This has 2 major benefits: infrared heaters are highly resistant to wind and the movement of air, and they allow you to directly warm specific areas.
