Because of their high temperatures, near Infrared emitters are suitable for high intensity heat applications such as cooking and welding or thermoforming plastics. The heat is not suitable for Comfort heating applications. Near Infrared is deeply transmissive into Human and animal skin and is not effectively absorbed. To avoid the potential for damage, the skin has evolved to reflect large amounts of this wavelength which will not result in heating. Only infrared in the longer wavelengths assists with heat absorption in human and animal skin. Near infrared risks thermal burns to human and animal skin if a near infrared heater is placed too close to skin or if exposure is too long and ageing effects such as Bakers Arms and Glass-blowers face and eye damage can result from long term exposure. For Comfort heating, Medium and Longwave infrared should be considered, which don’t possess these harmful effects. Please see the attached article “Preferred wavelengths in Comfort Heating“.
