Abstract

A method of reducing the resistance of a sleeping mammal to arising at a preselected wake up time by exposing the mammal to at least one source of artificial light for a period of exposure of at least about 0.5 hour and no longer than about 8 hours before the preselected wake up time. The intensity of the artificial light may increase during the period of exposure. an apparatus for carrying out the method comprises a normally deacutated source of artificial light capable of illuminating a mammal, comprising a plurality of electric lamps, a control device, such as a timer, for signalling the commencement of a period of exposure preceding the mammal's preselected wake up time and an increase in illumination intensity during the period of exposure, after its commencement. The apparatus further features circuitry and a power supply, responsive to the control device, for actuating one lamp in response to the commencement signal, and for actuating additional lamps later during the period of exposure.

Dependent claims

A method of illuminating a mammal having a preselected wake up time, comprising:

exposing the mammal to at least one source of artificial light for a period of exposure of at least about 0.5 hour and no longer than about 8 hours before the preselected wake up time, in which the artificial light increases in intensity as the preselected wake up time approaches, for at least a part of the period of exposure, said artificial light having a color temperature which remains substantially constant.
