That's something that you can do by just having lamps on, for example, instead of overhead lights or reducing the screen time in the evening.ĬB: So the schedule that we're on from November to March is really the biological schedule we should probably be on the whole year. Getting that morning light is really important, and then also having dim lights in the evening. Our internal clock runs on its own, but it's locked into the 24-hour day by time givers in the environment, such as the light-dark cycle. That morning light is really important for synchronizing our rhythm. This is why the switch to standard time is really better for your biology, because you're going to be getting that morning light sooner. KB: Our internal clocks are messed up by getting too much light at the wrong time and not enough light at the right time. How important is it to be following the patterns of nature? Do we still do that? Or in our electrified age of screens, should we be paying more attention to that than we do? It may take a couple of days.ĬB: We don't rise and sleep with the sun anymore. But they may be raring to go at the regular time, which is instead of 6 a.m., maybe 5 a.m. The kids tend to be a little bit more on the early spectrum, and eventually they do adjust. KB: Every parent knows that when it comes to the "fall back," they're looking forward to sleeping in and it's harder for the kids to do it. Not getting enough sleep increases blood pressure, increases risks of heart attacks and even early death, as well as increasing risk for car accidents and for depression.ĬB: What about kids and their reactions to time changes? Are they different from how adults can experience it? KB: We know that lack of sleep affects just about every aspect of health: mental health, physical health, safety. What kind of stress can that put on someone? For example, when you're jet lagged, your brain and your liver can be getting different signals if you're eating food at different times of day and that sort of thing.ĬB: You mentioned that many Americans are sleep deprived. There's actually clock genes and your cells and organs and organ systems have a rhythm. This is called the master clock, and it really coordinates the rhythms of different aspects of the body. KB: The internal rhythm is generated by the superchiasmatic nucleus - the SCN in the hypothalamus. We then have the “spring forward” and the opposite happens.ĬB: How many other systems are connected to your sleep cycle? When it's disrupted or changed, how many other things are changing with it? The “fall back” is actually a really good time of year. For those first couple of days, people feel better. And the other thing is that it reminds us that basically we're always going to bed later than we really need to. It's easy for us to get that extra hour of sleep. So this is the time of year that really reminds people that, first of all, at least a third of us or more are sleep deprived. So essentially people get an extra hour of sleep for those first couple of days. In your brain, you're going to bed at 11 o'clock, but the clock says 10. Essentially, it takes your clock a few days to adjust. Kelly Baron: "Fall back" is everyone's favorite. This interview has been edited for length and clarity.Ĭaroline Ballard: How does falling back an hour and resetting impact people’s sleep schedules? Baron explained to Caroline Ballard how the time change impacts the human body. She’s currently conducting research on the effects of sleep on cardiovascular disease. Kelly Baron is a clinical psychologist and director of the University of Utah’s behavioral sleep medicine laboratory. Daylight Saving time ends Sunday, putting an extra hour on the clock. ![]()
