For high schoolers, it&rsquo;s their last chance to hit the beach, hang out with friends all day, and, of course, sleep late.</p><p>Many Chicago Public Schools start as early at 7:30 a.m. CPS recently changed some school start times as a money-saving measure. But what effect does starting early or late have on health and academic performance? The Centers for Disease Control and Prevention has a new study on the topic where it analyzed data on millions of students. The lead author of that study, CDC epidemiologist Anne Wheaton, joins us.</p></p> Tue, 11 Aug 2015 10:53:00 -0500 http://www.wbez.org/programs/morning-shift/2015-08-11/how-school-start-times-affect-academic-performance-112620 Ways to look young forever http://www.wbez.org/blogs/claire-zulkey/2013-04/ways-look-young-forever-106529 <p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/2739606466_b57ef7dff9.jpg" style="float: left; height: 300px; width: 300px;" title="Flickr/Express Monorail" /></div><p>Do you know how old I am? No seriously, tell me. Because I&rsquo;m approaching that age where I start to forget what my actual age is. (I think it&rsquo;s 34, unless it&rsquo;s 43? It could be anywhere in there.) This is a true sign of aging, and it&rsquo;s definitely showing all over my body, this son-of-a-bitch we call time. Based on the somewhere-between-28-and-50 years I&rsquo;ve spent on the planet, these are the tips I&rsquo;ve learned for looking youthful. Just follow them strictly and you&rsquo;ll look even fresher than my baby son does. Truth be told, even though he&rsquo;s almost eight months old, it&rsquo;s a hard eight.</p><p dir="ltr"><strong>Don&rsquo;t drink. Don&rsquo;t smoke.</strong><br />Pretty much anything fun or cool: skip it. Any sort of life experience is just going to age you because chemicals suck the life out of your face and smiling gives you wrinkles and staying up late gives you bags under your eyes and makes you eat late night burritos which definitely isn&rsquo;t good for your neck. &nbsp;</p><p dir="ltr"><strong>Don&rsquo;t go outside.</strong><br />That wrinkle-and-spot-causing sun is outside, as well as toxins and other people and things who might annoy you or delight you and make you smile or frown, all of which will age you. Just stay in. Enjoy the darkness and the paleness.</p><p dir="ltr"><strong>Don&rsquo;t stress. Or think. </strong><br />Just sit there and avoid exposing yourself to news, work, the drama of friends or family or any sort of expectations from yourself or the world. Just chill. Forever. The downside is that nobody will be around to tell you how young you look, but the important thing is that you will know.</p><p dir="ltr"><strong>Don&rsquo;t have a baby.</strong><br />I just saw a picture of myself online that I thought was cute from afar but up close I look like <a href="http://www.youtube.com/watch?v=uzolCu-QLw0">the ghost of Large Marge</a>. I am pretty sure that the baby ate my youthful essence and I expelled it from my body with the placenta. I knew I should have eaten that stupid thing.</p><p dir="ltr"><strong>Sleep as much as you can.</strong><br />Go to bed right now. Just pack it up and go to bed, no matter what you&rsquo;re doing. You want a minimum of 12 hours a night with an extra three hours a day.</p><p dir="ltr"><strong>But don&rsquo;t sleep on a soft squishy pillow.</strong><br />I actually have read this in women&rsquo;s magazines. You know your down pillow that&rsquo;s reached the perfect amount of softness and has that great pillow smell that&rsquo;s so great for turning your face into when the morning sun rears its ugly head? Throw it out. Each time you turn your face into it it&#39;s like you&#39;re doing 60 pounds of meth. Best to sleep on your back with your neck resting on a cool piece of marble. And while you&rsquo;re at it, wear a bra while you sleep so your boobs don&rsquo;t age either.</p><p dir="ltr"><strong>Don&rsquo;t be thin.</strong><br />You know who have great cheekbones? Skeletons. And hardly anybody looks older than they do. It&rsquo;s true, you can choose either your fanny or your face, and I&rsquo;m starting to think that the smart people out there are choosing the part of their body that is nourished by Oreos and warm french bread.</p><p dir="ltr"><strong>Die early.</strong><br />It&rsquo;s really the only way to get out of this whole thing looking good.</p><p dir="ltr"><a href="https://twitter.com/Zulkey"><em>@Zulkey</em></a></p></p> Mon, 08 Apr 2013 08:52:00 -0500 http://www.wbez.org/blogs/claire-zulkey/2013-04/ways-look-young-forever-106529 Scientists link loneliness with lousy sleep http://www.wbez.org/story/scientists-link-loneliness-lousy-sleep-93650 <img typeof="foaf:Image" src="http://llnw.wbez.org//story/photo/2011-October/2011-10-31/518380699_4a4beef2d9_z.jpg" alt="" /><p><p>Loneliness has been linked to poor health, but it’s been unclear why. Lianne Kurina of the University of Chicago and her team <a href="http://www.journalsleep.org/ViewAbstract.aspx?pid=28332">tested the theory that poorer sleep </a>might be what predisposes lonely people to high blood pressure, heart disease and even earlier death.</p><p>The researchers examined 95 people from a close-knit religious community in South Dakota centered around farming. The subjects did interviews, and then wore a special sensor called a wrist actigraph for a week to measure their sleep.</p><p>“Our study population in general was not very lonely” says Kurina, an assistant professor of health studies at the University of Chicago. “So it was surprising to find that even subtle differences seemed to translate into differences in sleep patterns.”</p><p>Specifically, the lonelier subjects slept just as long, but tossed and turned more and had more frequent wakings. The subjects did not seem aware of the difference in sleep quality, as there was no difference in the subjective reports people gave of their sleep.</p><p>The results match up with an earlier study of college students, a much more diverse group with widely varying senses of loneliness. Kurina says the consistency of results across these two very different groups suggests it might be a wide-reaching effect. The authors of the study, which appears in <a href="http://www.journalsleep.org/">the journal Sleep, </a>speculate it might have to do with a basic need to feel connected and secure in order to sleep soundly.</p></p> Tue, 01 Nov 2011 01:40:00 -0500 http://www.wbez.org/story/scientists-link-loneliness-lousy-sleep-93650 Study: sleep loss saps testosterone http://www.wbez.org/story/study-sleep-loss-saps-testosterone-87259 <p><p>Losing sleep might sap men’s testosterone, according to <a href="http://jama.ama-assn.org/content/305/21/2173.extract">new research by Chicago scientists</a>. Men release most of their testosterone during sleep, so University of Chicago professor Eve Van Cauter wanted to see if less sleep meant less of the hormone.</p><p>She recruited volunteers and restricted their sleep to just five hours per night for eight days. At the end of that stretch, her team took blood samples to test for hormone levels. They found an average 15 percent drop in testosterone.</p><p>“And 15 percent is not an insignificant amount, since it is about the amount that occurs with normal aging by 10 to 15 years,” Van Cauten said.</p><p>So in one respect, a week of bad sleep is like aging a decade or more.</p><p>Testosterone plays a role in reproductive health, but also in insulin sensitivity, bone density and general vigor. Scientists are interested in how the reduction might affect everything from fertility to weight gain and diabetes.</p><p>The study sample was small – just 10 subjects – and limited to lean, healthy young men. There are many open questions, like how the effect might change over time and how it translates to women and older or overweight subjects. But the finding, out in the Journal of the American Medical Association, adds to growing evidence that sleep deprivation has big effects on hormone levels.</p></p> Wed, 01 Jun 2011 04:21:00 -0500 http://www.wbez.org/story/study-sleep-loss-saps-testosterone-87259
