How electric light changed the night

3 minutes

How artificial light affects our physiology and our sleep

Before the dawn of electric light in the early 20th century, humans mostly took cues from the Sun to determine when to sleep and when to stay awake. Now, however, our exposure to artificial light sources is nearly constant. While these extra hours spent in light are widely viewed as more time to pursue work or leisure, studies show they might also be playing tricks on our body and cutting against our default biological rhythms. How Electric Light Changed the Night combines a brief history of artificial light and sleeping patterns with a scientific exploration of the surprising ways artificial light affects us.
