Satish, Joseph, and Nanavati recap the benefits of natural light. They report that “Exposure to daylight, in particular, plays an outsized role in our overall well-being and mental health. Like almost all animals, humans have a circadian cycle that regulates sleep, metabolism, heart rate, and body temperature over a 24-hour cycle. Daylight is the main environmental stimulus that syncs the body’s internal clock with the external world. . . . Studies have shown that daylight access can reduce stress, lower blood pressure, and even improve a person’s cognitive function.”
