ipRGC Non Visual Effects of Light

Properties of Light Affecting Circadian Photoreception !Wavelength, Timing, Intensity, Pattern, Light History !

Most Sensitive to 460~490 nm Spectrum !

•  Constricts the Pupil Size •  Suppresses Pineal Melatonin Production •  Increases heart rate and core body temperature •  Stimulates Cortisol & Serotonin production •  Acts as a Neurophysiological Stimulant

•  Improves Reaction time •  Reduces Lapses of Attention •  Improves Alertness

A Prospective Study of Patients

Undergoing Spinal Surgery

•  The exposure postoperatively of patients who have undergone spinal surgery to increased amounts of natural sunlight during their hospital recovery period may result in decreased stress, pain, analgesic medication use, and pain medication costs.

•  The patients housed on the bright side of the hospital(46% higher intensity sunlight on average) used 22% less analgesic medication in all age quartiles. WALCH et al

Psychosomatic Medicine 67:156-163(2005)


Portland Providence Medical Center

•  Postpartum Patients and Recovery Time •  Staff Awareness and Medical Malpractice Reduction •  This project seeks to evaluate and quantify non-energy

benefits of lighting as it pertains to health, mood, productivity, safety and others.


Healthcare Implications

•  In 2010, the United States spent $40 billion on healthcare construction

•  0.5 Day Reduction of Avg Hospital Stay Can Save Annually $113M

•  Human Centric Lighting Can Achieve Greater Survival Rate, Faster Recovery, Longer Independent Living for Seniors and Less Pain and Stress After Major Surgery

•  Implication for Professional Athletes


Greatest Platform to Change the World

•  119 Teams •  MLB, MLS, NBA, NHL, NLL, USTA, WNBA •  First Publication of Lighting Playbook for

Sports Teams



Lighting for Increasing Winning Percentage

MNF Home Win% 71% vs EC 43.8% vs WC

MNF Home Win % 58.1% vs Non-EC 67.5% vs Non-WC

Because of the circadian rhythm, which they(EC) can't control, their bodies are past their natural performance peaks before the first quarter ends.
