We know virtual learning is mentally hard on kids, but what about physically? If your child is having persistent neck or back pain, it might be related to poor posture and poor body positioning.At some point during the pandemic, most children across the country were doing some sort of computer-assisted learning. At Children's Hospital of Orange County in Southern California, pediatric physical therapist Ruchi Bagrodia covers posture and seating with kids who are of age.There are many things they should be doing.“I always encourage them, a child, to sit at a dining or office table, a chair with a seat back. Their back should be supported,” Bagrodia said.There are lots of things they shouldn't do.“Never sitting on the floor, never sitting in bed, never sitting on the couch,” Bagrodia said. “For therapy appointments or learning, it promotes poor posture if you’re in a squishy bean bag chair or couch. You’re never going to sit up well if you’re there for a couple hours. You’ll develop all sorts of kinks and achiness in the neck, the shoulder, the back.”Many Americans are at home, and these days, many are in chairs a lot. If you're using a device, it matters where you put it. “The level of the tablet, the height of it matters,” said Bagrodia. “We want it arm’s-lengths away and the top of the screen should be just below your eye level. If you’re on the floor and your tablet is on your lap, you’re going to be looking down at your lap and that can develop shoulder neck pain, achiness.”When asked about the long-term implications of persistent bad posture, Bagrodia said, “Poor posture is something is that is developed in a 6- or 7-year-old by the time they’re 20, maybe they do have serious back pain or issues.”While you're repositioning your children, doctors say, pay attention to their mental health too.“Across all different mental health issues, we’re seeing a marked increase, everything in kids. We’re not just talking one age range, we’re talking young childhood all the way through late teenagers,” says Dr. Christopher Min, a pediatric psychologist.Dr. Min says kids need the structure, stability and routine that school provides, and that is what's missing for a lot of kids.“Kids' bodies and brains do really well, “ Dr. Min said. “We’re creatures of habit, when they have that regularity, it’s really great for their brains.”Dr. Min says try to provide some sort of routine and make sure you incorporate enough physical activity, such as a daily family walk. And he says there are signs when things are not going well for children.“For kids, a sign of some mental health difficulties is irritability (which) is a symptom of anxiety and depression in kids,” Dr. Min said.He recommends to pay attention to sleeping and eating habits. While you can't do everything, you can definitely make sure children are consistently physically comfortable while learning at home. That doesn't mean you need a fancy or expensive desk.“If the chair is too high and their feet is hanging off, then put a box or laundry basket underneath their feet so they’re supported. If the laptop is really low, then put books or something under the laptop to lift it up, put a cushion if the chair is too big, put a pillow, or roll up a sweatshirt and tuck it under the low back for some support,” says Bagrodia.At the same time, if you are sitting for long periods of time, check your positioning as well, since it appears the work from home life won't be sitting anytime soon. 3488

We're all familiar by now with the student walkouts in solidarity against gun violence. It's one way they've united in one voice to try to make a difference.  But some students are using art, and billboards, to send a message of their own.           For Yoki Ogbai, the overalls she's painting are more than a school project"Our colors are red and white," Ogbai said. "So a lot of wings a lot of bows glitter all types of crazy.The overalls are her latest work of art."Art for me is like a big sense of release," Ogbai said.Born in East Africa, she used art as expression when she moved to the U.S and a way for people to see her for who she is."A lot of times people don't really try to understand and don't really try to get to know a person before creating their onw ways," Ogbai said.  "Their own idea of who you are."So when she heard about a contest called the "Healing As One" campaign, she figured it would be an opportunity to inspire thousands to take a look at things in a different way."Cause he's kind of taking a picture and was like through the lens," Ogbai said.That idea grew into a billboard on a busy intersection that reads, "See Me, I Am Denver.""To be seen is to be acknowledged for everything you are and not for what you're expected to be," Ogbai says.Ogbai's billboard is just one of several in the Healing As One initiative. The topics are timely. One reads education not deportation. And others, encourage people to have courage and hope.Albany Reynolds designed the hope billboard."For me it's amazing because I've always been someone who wanted to speak out about issues like that," Reynolds said.  "And just bring attention to that."She placed the word over a picture she took of her classmate Kelly."It's giving us leeway to have artistic freedom and to put our ideas out there," Reynolds said. "And to say I want to represent hope and to have that on an actual billboard it's a good opportunity."In a time with young people across the country speaking out about the issues important to them, this group believes doing that through art can be just as powerful."If you look at any big historical changes throughout history art has been a very big part of that," Reynolds said."Even though I am just another person using my voice and what I know what I can do I really am able to make some sort of impact in someone’s life," Ogbai said.Inspiring change through billboards, advertising messages of a different kind. 2526

  

WASHINGTON (AP) — Winter hit U.S. honeybees hard with the highest loss rate yet, an annual survey of beekeepers showed.The annual nationwide survey by the Bee Informed Partnership found 37.7% of honeybee colonies died this past winter, nearly 9 percentage points higher than the average winter loss.The survey of nearly 4,700 beekeepers managing more than 300,000 colonies goes back 13 years and is conducted by bee experts at the University of Maryland, Auburn University and several other colleges.Beekeepers had been seeing fewer winter colony losses in recent years until now, said Maryland's Dennis vanEngelsdorp, president of the bee partnership and co-author of Wednesday's survey."The fact that we suddenly had the worst winter we've had ... is troubling," vanEngelsdorp said.Some bees usually die over winter, but until the past couple decades, when a combination of problems struck colonies, losses rarely exceeded 10%, he said.Bees pollinate billion worth of U.S. food crops. One-third of the human diet comes from pollinators, including native wild bees and other animals, many of which are also in trouble, according to the U.S. Department of Agriculture."We should be concerned on multiple levels," said University of California, Berkeley, agricultural social scientist Jennie Durant, who has a separate study this week on loss of food supply for bees.Year-to-year bee colony losses, which include calculations for summer, were 40.7%, higher than normal, but not a record high, the survey found."The beekeepers are working harder than ever to manage colonies but we still lose 40-50% each year... unacceptable," Swiss bee expert Jeff Pettis, who wasn't part of the survey, said in an email.For more than a decade, bees have been in trouble with scientists blaming mites, diseases, pesticides and loss of food.This past winter's steep drop seems heavily connected to the mites, vanEngelsdorp said. Beekeepers report that chemicals that kill mites don't seem to be working quite as well and mite infestation is worsening, he said. Those mites feed on the bees' fats and that's where the insects store protein and center their immune response.Durant's study in this week's journal Land Use Policy found that changes in food supply in the Midwest's Prairie Pothole Region, a hot spot for honeybee colonies, has been a major factor in losses. That area has lost wetland areas with clover bees feed on.Other areas have been converted to corn and soy crops, which don't feed bees, she said.As bad as the survey numbers are, vanEngelsdorp said, "We're not really worried about honeybees going extinct... I'm more worried that the commercial beekeepers will go out of business." 2695
