there's light, it must be daytime, and then it doesn't do what it's supposed to do. And my evidence, a study in Japan of 800 people show that the amount of light that leaks in around your curtains from streetlights increases depression by 69%. It literally makes you old, it makes you insulin resistant. So blackout your room, you don't have to do any of the tracking, just do that.

there's a good chance that you might not succeed in getting her to do the TV thing. You can get the true dark glasses. True dark is a circadian biology company. I started it 10 years ago. These are the daytime glasses I'm wearing right now. The yellow ones, we make glasses for sleep that are on the true dark.com website.

And we just published in a medical journal, a study of brainwaves and 15 minutes of wearing the true dark glasses and put your brain in a state of meditation, and they trick your brain into thinking it's pitch dark, even if there's light. So even if she's got those on, you put on those glasses, you'll look a little bit like Cyclops from the X-Men.

They make a really big difference. And I mean, even my girlfriend, who's super cute and didn't know any of this stuff. It's so funny. We fly somewhere. We're in a hotel and we're both walking through with these red glasses on and people think they must be celebrities or something like, sure, whatever. We just want to sleep tonight.
