at the cognitive level. That's all true. That's all well and good. But there are some things that are going to go on physiologically, even if you're taking out a phenol and this is base, I'm saying this not based on speculation, but based on observations and published scientific studies. Okay? Okay. So now we need to know what goes on physiologically when we restrict Cells to five hours of sleep a night. And there's there's a lot of really good, really solid data out there. And I'm going to do my best to summarize it in just a couple of minutes here. Okay. So what happens when we get eight, nine, ten hours of sleep. That doesn't happen when we get five hours of sleep. Well, let's see. First of all, when we restrict ourselves to five hours of sleep, we lose our insulin sensitivity. Okay, we undergo a state of insulin resistance, if we have 5 hours of sleep a night. So what that means is that muscles, you know, if you think if anyone's listening and is interested in athletic performance, if you're going to have good athletic performance, you've got to have good glucose absorption into the muscles so they can take. That glucose is converted into glycogen. Use it later for your athletic performance. If you have five hours of sleep a night, the muscles lose the ability to store that glucose. They become insensitive to insulin, okay? If you take mode, Methanol to help keep you awake. When you are undergoing, only five hours of sleep a night that loss of response to insulin still occurs. Okay, so you may be wide awake, your brain says, hey, I'm great. I'm feeling fine. Your muscles are saying, I'm not going to pick up any glucose. I'm not going to deposit glycogen. Okay, right. So and that's this is scientific. This is published is something that's been studied systematically other things. Cortisol is our stress hormone, right? Our fight, or flight from hormone under normal circumstances. If you're getting eight, nine, ten hours of sleep a night. You're going to get a burst of cortisol in the morning and that's good. I mean, this is preparing you for the day. This is preparing you to use those muscles that you have used the previous that you have stored up glycogen, and the previous night. And so, and so you had that burst of cortisol and then in the evening, the cortisol goes down and it disappears. And the cortisol actually will inhibit the response of muscles to insulin. Right. And so this is why it's good in the evening. The cortisol drops, you get the insulin signal that the muscles can detect both the absence of cortisol and the presence of insulin. They say okay time to store some glucose. And then that's what they do. People who are restricted to 5 hours of sleep, a night either voluntarily or under a, you know, a research protocol will have that cortisol continuing into the night and the cortisol being there, suppresses the response to insulin. And so, again, you have that reduced muscle mass building of muscle mass. If you're restricted to 5 hours of sleep that increase in cortisol, in the evening that will occur whether or not you're taking modafinil, take you mode. A fantail, your brain says, hey, everything's great, your muscles, getting a signal from cortisol that says this is fight or flight time. This is not time to store glucose. It's time to burn glucose.
