A nightlight provides therapeutic effects on the human body and mind including promoting relaxation, sleep and wakefulness. The nightlight includes a housing, a light source, a central processor, one or more controls, and a power supply. The light source produces at least three illumination modes having various light properties. The light modes include a sleep readiness mode, a sleep help mode and a wake-up mode. The sleep readiness mode produces light at about 40 lumens and preferably includes only light from the blue and yellow portions of the visible light spectrum. The sleep help mode produces substantially monochromatic light in the blue or green spectrum. Preferably, the light undulates at a frequency of one cycle per second to one cycle per minute at a luminosity of between 5 lumens and 25 lumens, which can be selected to automatically decrease by the user. Meanwhile, the wake-up mode produces substantially full spectrum light at approximately 1,600 lumens. The controls allow a person to control the various light modes. Moreover, the nightlight may include biological sensors for measuring physiological activity of the body. The nightlight may be incorporated into a bedside alarm clock which includes numerous features found in a traditional alarm clock such as a display for displaying the time or alarm time. The alarm function may be provided by illumination of one of the three nightlight's illumination modes, which is preferably the wake up mode which may illuminate slowly or substantially immediately to full brightness.
