Daylight

Leon’s work has ramifications for the design of spaces where UV radiation might be present.  He reports that “Temperature may be a proxy for UV radiation in the heat-aggression association. . . . Heat is associated with human aggression in field research, assumedly by affecting emotions, but it is not in laboratory experiments. Since this may be so because temperature functions as a proxy for UV radiation in field settings, not in the laboratory, this research tested, across 126 countries, whether temperature loses its predictive capacity when the electromagnetic variable is controlled.

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.”
