Lynne Peeples, a science journalist, dove 50 feet underground for ten days to investigate how humans adapt without natural light cues. She chose an Arkansas Airbnb that was once a Cold War bunker to explore how factors like meal times and light affect sleep patterns. Peeples made the bunker sunlight
You might not think about it, but the time of day you get your cancer treatment could make a difference.
