Twice a year, Americans change their clocks. Twice a year, we argue about whether we should stop. But what does the science actually say?
Stanford sleep researcher Dr. Jamie Zeitzer joins Atmosphere to unpack the surprisingly complicated science behind daylight saving time. Is permanent standard time really healthier? And are we overlooking a much bigger problem while arguing about the clocks?
From the Sunshine Protection Act to our alarming lack of natural daylight, Jamie explores how sunlight affects our circadian rhythms, sleep, and overall health. He also shares surprisingly simple ways to get a better night's sleep, explains why some of us are night owls while others are early birds, and challenges some conventional thinking about changing the clocks.
Maybe the problem isn't what time we're setting our clocks. It's what we're doing with the daylight we've got.
