Talieh Ghane researches the interaction between light and health at the California Lighting Technology Center. We talked about the biological vs. visual system of light, how to synchronize your circadian clock for better health, how light is like a drug, and why you shouldn’t be on your phone right before bed (guilty).
Our relation to light as humans is complex. Though many of the effects of light on our biology are still unknown, there are several we know and understand. Light also plays a major role in regulating human biological responses, including our internal body clock or circadian rhythm.
The benefits of LEDs are well studied and documented. By now we know that it’s much healthier for humans to work, function, and operate in environments that are lit by LED lighting. Without a doubt, LED technology will continue to change how we light our environment and our world. So why then, are our students and teachers still spending a significant amount of their days in classrooms and schools under dull and dated fluorescent lights?
Have you ever had trouble falling asleep at 2am after binge watching the latest season of House of Cards? Ever pulled an all-nighter then felt strangely awake and alert after walking outside into broad daylight? Ever spent all day at the beach only to sleep like a moss-covered boulder later that night? It probably comes as no surprise that light has significant effects on the human body.
