Ep 199 Sleep Part 2: Predictably unpredictable

Ep 199 Sleep Part 2: Predictably unpredictable

Now that we know just how critical sleep is, we’re all making sure we get the amount we need, right? Unfortunately no. One-third to one-half of Americans are not getting enough sleep, according to public health guidelines. Why is that? Hypotheses abound, but many point the finger of blame at different aspects of modern society such as screen time, artificial light, a sedentary lifestyle. These narratives suggest that sleep in industrialized societies today is not just different but worse than in centuries past. Is that the truth? How did humans sleep in yesteryear, and what can that tell us about sleep today? In the conclusion to our sleep two-parter, we explore the many ways that humans sleep and the wide array of consequences when we don’t get enough (or too much) of it.
