Uh, good question. No, not on the Apple Watch yet. We'll get back to that. Francois, okay? So National Sleep Foundation. They have their own journal now, you know, and they're pretty bonafide organization. They have a lot of good sleep education out there. They're supported by the American Academy of Sleep Medicine. So they're like, bona fide sleep expert, or source of expert sleep information, and they did a meta analysis, and what they looked at was the importance of sleep regularity. Right now, if you think about it, sleep regularity, to look at sleep regularity, there are variety of different ways, but the general idea is you're looking at having regular bedtimes, regular wake times, and so if your bed and wake times are varying, you're going to have a high sleep a low sleep regularity. If you're having regular sleep during the week, but you're adding naps on the weekend, well, that will show very different bed and wait times, right? You're having something that's very different than the day before or the two days after, for instance. So that's going to increase and make your sleep look less regular if you're napping. So presumably, napping will give you a worse sleep regularity score, and we're looking at the importance here of sleep regularity. Okay, so now we get into really interesting things. Okay, so the first line of their discussion, right? Doing this meta analysis, they ended up including something like 290 some odd papers, okay, over the past decade, and what they come up with is this. Our review found that across a wide variety of health and performance outcomes, mortality, inflammation, cognitive performance, metabolic indicators, breastfeeding and mental health increased, sleep, timing variability, right? Worse regularity. Right was associated with adverse health and performance outcomes. Okay, simply put more variability, worse health. That was the first line of their conclusion. And you can look up the paper and see the same thing I saw. But this is the way politics and sleep works their conclusions in the abstract of that paper, you know, just the short version, just to show you what was going to be in the paper you were about to read. Says, Excuse me, consistency of sleep, onset and offset timing is important for health, safety and performance, very consistent, right with what we saw their first line of the discussion. Nonetheless, when insufficient sleep is obtained during the week, work days or the weekend, non work days, catch up sleep may be beneficial, direct conflict with their conclusions. It's just kind of like, that's why I don't have any hair left, really. It just, you know, I pulled it out reading these studies over the years. So they really just go, Well, yeah, maybe Okay, that's where they're left with napping on the weekends to make up for lost sleep. Now, I should have probably given you a caveat, and you know, at the beginning, you all have to agree that this is not medical health information, right? You have to see your doctors and all that stuff so but this is, this is why, when something comes out in the media, you you have to take it with a grain of salt, and especially if it goes against the grain of what, what's always been out there. You do take note of it, and what you do then is you hold it in one hand and you wait for more data to support it coming down the pike, because that sort of paradigm breaking information. It may hold up or it may not okay, and so that's where this is that's why they're kind of waffling at the end with their conclusions. So last month, I presented on napping, right? And you know, we talked about napping, it's the question, do we nap or do we not nap? And I was even surprised to find that the meta, meta, that meta analysis we just talked about, was done in 2023 This one's done in 2024 they reviewed all these studies, a variety of studies, including a lot of the same studies, and they came up with, there may be significant adverse cost to napping, especially habitual napping, increase the risk of several adverse health, health outcomes, including all cause mortality, cardiovascular disease, metabolic Disease, Cancer. It decreased the risk of cognitive impairment and sarcopenia age related muscle loss, so that extra sleep seems to have some benefits, but not in terms of cardiovascular and so these findings controlling for napping, duration, frequency, age, sex, BMI and follow up years, all these variables, this still showed up with adverse costs to mortality, in general, cardiovascular disease, metabolic and cancer specifically. Do we now or don't we now? Okay, let's continue. So I also presented this, I think to two months ago, sleep regularity is a stronger predictor of mortality risk than sleep duration. Hmm, now we're going back to sleep regularity, right? So, and this is this. These are full papers, again. The first thing we looked at was just a presentation at a meeting. It hasn't been peer reviewed, and all that stuff. But I wanted to show you this data, because these guys are looking at the same data. They're looking at 60,000 of the same UK Biobank data. They they looked at these people back eight years ago, and they gave them the same accelerator, you know, same actigraphy, recording their movement and assessing sleep from that to semi objective measure, right? Because you're wearing something, and then you mark your sleep logs, and we see if they coincide. And the algorithms are pretty good at pulling out sleep from Wake, okay. And what they found was that sleep regularity was a better predictor of longevity at eight years. So if you were less regular, if you were very irregular in your sleep, which means you were having naps as well as changing your sleep and wake time, you were more likely to not be alive in eight years than if you are very regular with your schedule. Now, an important caveat there is there was longer sleep duration associated with higher sleep regularity index scores. Okay, so you had to be basically still coming pretty close to meeting your sleep need, which is on average, close to eight hours a night, on average, right. And then if you were sleeping above which longer sleep duration was associated with lower SRIs. So what they were finding was that people who slept longer for all reasons, and there are reasons, you know, there's this U shaped curve with sleep duration. People who are sleeping 10 hours and longer seem to have higher mortality, peeping with people sleeping six hours or less have higher mortality, and they're in the same relative risk of mortality. And so somewhere between six and 10 hours is that average, where we want to be, where most people are, and smack in the middle of that average would be eight hours sleep. Regularity was a significant predictor of cardiometabolic metabolic cancer and other mortality risks, and such that sleep irregularity was associated with higher cardiovascular cause of death. So you can see this is in direct conflict with the study that you know Barry pointed out, so I want to open the floor a little bit to that discussion. Any any comments about that those days? Data, those studies, are you going to start napping? Are you going to stop napping, or you're not going to change any behavior? Barry? Barry's hand is up.
