  • the comfortable warmth created by infrared light penetrates deep into the skin of a person, improving blood circulation and warming muscles. As the muscles are soothed, they automatically loosen up and relax.
  • the improved blood circulation helps the irradiated body part get rid of impurities and quickly sends oxygen-rich blood to stressed or aching muscles, bringing effective pain relief.
  • appliances enabling consumers to irradiate body parts with infrared light are commercially available.
  • appliances for heat therapy of a human body part by means of radiation and their use are presented.
  • a heat therapy appliance for treating a subject comprises a first light source configured to provide infrared light with a first spatial illumination intensity distribution.

  • the sensor may comprise one or more portions which are transparent to the infrared light of the first light source or it may comprise a remote sensor, e.g. a bolometer.
  • the first spatial illumination intensity distribution can be modified to account for (i) the position of the subject relative to the light source and/or (ii) global and/or local variations in absorbance of the skin and underlying tissue of the subject for the infrared radiation due to (local) venation, skin tone, moles, bruises, scars, delicate body portions, etc.

  • user comfort of the appliance is improved.
  • user safety can be improved by providing a safety function, e.g. by preventing the light source to heat a portion of the illuminated skin beyond a predetermined temperature, e.g. 45 degrees Celsius.
  • the treatment may be tailored to the specific needs and conditions of an end user. Since infrared devices generally are employed in the field of "self medication” the personalization factor is relevant for delivering an optimal "feel good” experience.
  • the controller may be configured to modify at least part of the first spatial illumination intensity distribution of the radiation in at least one of a spatially- varying and a temporally- varying pattern.

  • This latter situation may be referred to as quasi-static illumination.
  • the light source may be configured to provide only a small size intensity distribution, relative to the size of the skin portion to be illuminated, e.g. a narrow beam laser. This allows improving cost- effectiveness of the appliance.
