UNM hospital room lighting

Light affects sleep - especially our circadian rhythm, or the timing of our sleep. The University of New Mexico has built a hospital room with special lighting equipment that researchers will be able use to study the circadian rhythm of humans. The researchers will also be able to study how light effects certain neurological and psychiatric disorders such as delirium after surgery, depression, dementia, and psychosis that develops in ICU patients. Apparently, the lighting is "smart" in that it can alert a nurse that a patient has fallen, but the lighting uses no cameras! Not sure how that works, but it sounds pretty cool to me.
