Well, to some extent. I did have LED lights in this bunker. So kind of a non-traditional bunker. This was a souped-up former Cold War era bunker that somebody had purchased and set up as an Airbnb. And so he had LED lights throughout the bunker, which... I could tune.

And because I had learned that red light is the color that's least likely to affect our circadian rhythms, I set the entire bunker to a dim red light. So I could see. I had some light, but it was nothing like what we experience indoors or especially outdoors. So absolutely no daylight and then none of those blue wavelengths of light that are known to particularly affect our circadian rhythms.

Yeah, I wanted to get a sense of, well, my personal rhythms. We all tick a little differently. And so I wasn't totally clear on just how my inner clocks ticked. You know, where was I on that spectrum of night owl to early bird? And then just what happens when we throw our clocks out of sync? I knew that from my research up until that point that cutting myself off from things

daylight, and from any other cue as to the time on the Earth's 24-hour clock, could throw those clocks out of sync with each other and out of sync with the sun. And we all experience that, at least acutely, when we travel internationally. We get jet lag, right? And so I wanted to get a sense both

qualitatively with how I felt as well as quantitatively what that kind of looked like and how those paired up. So I decked myself out with a whole bunch of different sensors. So I was measuring my temperature of various body parts. I was measuring my heart rate. I had a glucose monitor. I was checking my light exposure as well. And all that data

I had uploaded, but I wasn't looking at it until after the experiment when I had scientists help me kind of tease apart. How were these various clocks in my body ticking throughout those 10 days? How did they change? How did they drift both apart from the sun and apart from each other?

Oh, yeah. About halfway through is when I really started to feel it. And halfway is very subjective, right? I had no sense of time. I had no access to clocks. But about halfway through, yeah, during the day, I could feel my temperature rise and fall in seemingly unnatural ways. Middle of the day, I'd be kind of hot and sweaty. And then I'd get cold. I'd feel... kind of this brain fog.
