they are more alert and less stressed.

Because their bodies function more efficiently under full spectrum light, “Sundowners Syndrome,” a condition characterized by a lack of focus, concentration and alertness that may occur when the sun goes down, is eliminated. The elderly are more awake during the day and sleep better at night. Full spectrum light, like natural sunshine, activates all the cells in our eyes. We may have up to 80% more visual acuity than with standard indoor light. When we see better, we maintain our independence longer. The cells in the retinas of your eyes will not divide and regenerate without a small amount of ultraviolet light. And so full-spectrum light reduces the risk of retinal degeneration, the leading cause of blindness among the elderly.

Full spectrum light improves our quality of life. In a study reported in the American Geriatrics Society, researchers found out "the effects of low-power light therapy on pain and disability in elderly patients with degenerative osteoarthritis of the knee".

Interests such as reading the newspaper or putting together a jigsaw puzzle can be possible again under full spectrum light. Everyday tasks, such as cooking, cleaning, reading a prescription label, become easier. Full spectrum light pulls cholesterol from the blood, makes vitamin D3 in the skin, which strengthens teeth and bones. They may be able to work with their doctors and reduce prescription medication.
