Light in schools and universities
Classroom lighting affect students’ circadian systems which may in turn affect test results, attendance and behavior.
Exposure to light, or lack thereof, plays a significant role in sleep cycles.
Humans, have evolved circadian rhythms, which respond to the earth’s 24-hour cycle. These rhythms include the sleep–wake cycle, hormone production, and core body temperature cycles. The timing of these patterns is set by the 24-hour light–dark cycle. In particular, short-wavelength”blue” light in the daylight spectrum has maximal effect on human circadian rhythms.
Research has shown that when these patterns are disrupted, individuals are more susceptible to ailments such as breast cancer, obesity, sleep deprivation, mood disorders, and other health problems.
