Quizplus · Accepted Answer

Maintaining a regular schedule of eating and physical activity can help regulate circadian rhythms and promote better sleep, even in the absence of natural sunlight. Napping for short intervals may also be helpful, but it is important to also have a consistent wake-up time and bedtime. Option A is incorrect, as exposure to natural sunlight is important for regulating circadian rhythms. Option B is not the best choice, as it can lead to sleep deprivation and disruption of circadian rhythms.
