WELL AP WELL-AP Exam - Topic 8 Question 19 Discussion

Actual exam question for WELL AP's WELL-AP exam

Question #: 19
Topic #: 8

Exposure to which of the following contributes to Orcadian photoentrainment. resulting in a "phase advance'' shift of the circadian phase?

ALate morning sunlight

BEarly morning sunlight

Ctarty evening computer monitor illumination

DLate afternoon computer monitor illumination

Show Suggested Answer

Suggested Answer: B

Exposure to early morning sunlight plays a critical role in circadian photoentrainment, helping to synchronize the body's internal clock with the natural day-night cycle. This exposure, particularly within the first hours after dawn, can induce a 'phase advance' shift in the circadian phase, promoting earlier sleep and wake times. This alignment with natural light patterns supports overall well-being, improving sleep quality, mood, and cognitive function. The WELL Building Standard recognizes the importance of natural light and its impact on circadian rhythms, advocating for building designs that maximize the use of daylight while minimizing disruption to the body's natural cycles, thereby fostering environments that support the occupants' health and well-being.

I’m confused about the computer monitor options. I thought screens were generally bad for sleep, but maybe late afternoon light could help?

Okay, I remember learning about this in class. I think it has to do with the timing of light exposure and how that affects the body's internal clock.
