The central idea in both passages is the crucial role that light, particularly sunlight and blue light, plays in regulating our sleep patterns through the production of melatonin.

Question

In Passage 1, Priyanka Walker explains how melatonin, the sleep hormone produced by the pineal gland, is primarily triggered by the absence of sunlight. The text states, “Sunlight hits our eyes...and this connection of sunlight to the release of melatonin is crucial to keeping us on a healthy sleep schedule,” emphasizing the dependency of melatonin production on light exposure.

Similarly, Passage 2 by Tyler Jackson highlights the specific impact of blue light on our circadian rhythm, noting that “blue light from the Sun is especially prevalent at dawn and dusk” and that it plays a pivotal role in signaling the body to stop or start melatonin production. Jackson further explains how artificial sources of blue light can disrupt this natural pattern, leading to sleep disturbances.

Together, these texts illustrate that both natural sunlight and artificial blue light significantly influence melatonin levels and, consequently, our sleep-wake cycles.

Answer 1

The central idea in both passages emphasizes the essential role of light, particularly sunlight and blue light, in regulating our sleep patterns through melatonin production. In Passage 1, Priyanka Walker discusses how melatonin, the hormone responsible for sleep, is primarily triggered by the absence of sunlight. She notes, “Sunlight hits our eyes...and this connection of sunlight to the release of melatonin is crucial to keeping us on a healthy sleep schedule.” This highlights the dependence of melatonin production on exposure to light, underscoring the importance of natural sunlight in maintaining a regular sleep routine.

Likewise, Passage 2 by Tyler Jackson sheds light on the specific effects of blue light on our circadian rhythms. He points out that “blue light from the Sun is especially prevalent at dawn and dusk,” which plays a critical role in signaling the body to initiate or halt melatonin production. Jackson also warns that artificial sources of blue light can disrupt this natural process, leading to potential sleep disturbances. Together, these texts illustrate how both natural sunlight and artificial blue light significantly influence melatonin levels and, in turn, our sleep-wake cycles.
