00:00and melatonin is a naturally occurring hormone and it simply tells your brain and your body

00:05when it is darkness, when it is night, which is to say melatonin helps with the timing of our sleep

00:11and there are ways that you can artificially delay your natural melatonin release. A good one

00:19would be being exposed to too much light in the evening, too much artificial light, what I would

00:24think of as junk light. You know, there was this concept a while back of junk DNA. Well, I think

00:29there is something called junk light and we get too much of it at night because we are a dog deprived

00:34society in this modern era. But there's other ways that you can delay your natural biology. And if

00:41let's say that all food was taken away, all electric light was gone, all internet service was down and

00:48you know, the lights were out. You would naturally say to me, well, I'm someone who would probably not

00:52get sleepy until midnight. And then all of a sudden, as I said, no food, electromagnetic pulse

00:59takes out all electricity. Everything is gone. All of a sudden you probably say, gosh, it's 10, 15 PM.

01:19natural sensation of biology telling us it's time to sleep. Most of us think that, well, I'm

01:27probably, you know, a midnight to 8 AM type person. When, if I took you camping in the Sierras for two

01:34weeks and we had all of our sort of fancy technology measuring your sleep, wake rhythms, and we would

01:40actually find, you know, you're much closer to a 10, 20 to 6, 30 AM kind of person. But modern sort

01:49of industrial life has come in the way of that. And it is modified our perception.
