The Real Reason You Can't Sleep With the Closet Door Open

Tonight, you'll close your closet door before bed. You won't think about why. You'll just do it. But the real reason has nothing to do with monsters — and everything to do with what happens the moment your eyes stop working. In this video, you'll discover why 200,000 years of evolution wired your brain to treat darkness as danger, why your amygdala reacts before your conscious mind even catches up, and why the fears that make no logical sense today — the dark, heights, spiders, snakes — are still the ones your body takes most seriously. Drawing on the work of evolutionary psychiatrist Randolph Nesse, phobia researcher Isaac Marks, and neuroscientist Joseph LeDoux, you'll see exactly why closing that door isn't irrational at all. It's ancient.
