ABSTRACT:
Methods and apparatus are disclosed for warming a typist's hands to provide relief from arthritis, muscle fatigue, Carpal Tunnel Syndrome and general discomfort. A radiative hand warming apparatus is disclosed, including a source of hand-warming radiation, and a holder for supporting the radiation source in proximity to a keyboard or other manual operation device, such that the user's hands can be warmed by radiant energy during typing. In one embodiment, the source of hand-warming radiation emits radiation having an intensity of about 10 to about 750 milliwatts/square centimeter as measured at the typist's hands. The radiation source can be, for example, an infrared (IR) radiation source. Such an infrared radiation source preferably emits IR radiation in at least a portion of the spectrum from about 1 to about 30 micrometers.
