growth hormone. It's the same thing. We need are deep slow-wave sleep, in order for us to have that surge of A hormone that occurs at night, if you restrict someone to 5 hours of sleep, they don't have that surgeon growth hormone. That's true whether or not they are taking one Avenue at the time. Finally, melatonin. I don't, I think people are a little more excited about melatonin than I think the data often often supports, but we have an increase in melatonin at night. When we get eight, nine, ten hours of sleep, that increase is blunted when we have five hours of sleep, and if you have five hours of sleep and your Letting yourself with modafinil that melatonin is still lost.
So, yeah, so you're
paying a physiological and hormonal price for your time, spent awake.
