Healthy kids do better in school — something parents need to think about as they prepare for a new academic year. “As a parent and grandparent, I know that back-to-school time is a busy time. Yet, I encourage parents and students to be mindful of some health essentials to add to your to-do lists,” said Dr. Robert Redfield, director of the U.S. Centers for Disease Control and Prevention. “Getting a flu shot this fall, frequent hand-washing, and staying active all contribute to a healthier and more productive academic year,” he said in a CDC news release. Hand-washing with soap and water is one of the best ways to remove germs, avoid illness and prevent the spread of colds, flu and other diseases to others. At school, students should wash before eating; after using the toilet; and after blowing their nose, coughing or sneezing. Healthy eating and physical activity are also important. Most children consume nearly half their calories at school, making it an important place to learn and practice healthy eating habits. Physical activity can ease anxiety and help kids focus in school. Experts say children should get at least 60 minutes of physical activity a day. They point out that nearly 20% of U.S. kids are obese, making them more likely to have health problems such as asthma and high blood pressure, and to… read on >

If you often find yourself dosing off during the day, new research suggests it might be an early warning sign that you have Alzheimer’s disease. Areas of the brain that keep you awake during the day are damaged in the early stages of the memory-robbing disease, which is why people with Alzheimer’s may nap excessively long before they start to struggle with forgetting things, the study authors said. Not only that, the scientists also found that damage to brain regions involved in daytime wakefulness was caused by a protein called tau. This provides more evidence that tau may play a larger role in Alzheimer’s than the more extensively studied amyloid protein, the researchers noted. “Our work shows definitive evidence that the brain areas promoting wakefulness degenerate due to accumulation of tau — not amyloid protein — from the very earliest stages of the disease,” said study senior author Dr. Lea Grinberg. She is an associate professor of neurology and pathology at the Memory and Aging Center and a member of the Global Brain Health Institute at the University of California, San Francisco (UCSF). Previous research has suggested that excessive napping is due to poor sleep caused by Alzheimer’s-related disruptions in brain regions that promote sleep, or that sleep problems themselves contribute to Alzheimer’s disease progression. In this study, the researchers analyzed the brains of 13… read on >

Binge-watching episodes of your favorite shows does no favors for your brain, an expert warns. “It’s important to recognize that the brain is not an isolated organ — it responds to its environment,” said Dr. Randall Wright, a neurologist at Houston Methodist in Texas. “When we binge-watch, we create an unhealthy environment for the brain because we’re sitting for long periods of time, isolating ourselves from social activities and eating large amounts of unhealthy food.” Wright likens the instant gratification of watching episode after episode of a show to wanting to continue gambling even after you win. If you indulge often, this cycle and the side effects of binge-watching can lead to harmful brain and body changes, he said in a hospital news release. In other words, it’s a problem when watching a third, fourth or fifth episode of your favorite show replaces healthy activities, he said. But here’s the good news: You don’t have to stop cold-turkey. There are a number of ways to ward off negative effects of binge-watching: First, be sure it doesn’t prevent you from getting enough sleep. “Before you start your show, determine what time you need to go to bed to get enough sleep. It might be helpful to set a bedtime alarm so that you don’t lose track of time and to help you stick to that decision,”… read on >

A well-organized backpack helps ensure that your child has everything needed for school. Problems start when it becomes overloaded. Lugging around a heavy pack can lead to bad posture, back pain and worse. The problem is so pervasive that the American Occupational Therapy Association created National School Backpack Awareness Day. It’s held every September to share ideas to keep kids safe. You can protect your kids by making sure that their packs are properly fitted and properly loaded. Here’s how. When shopping for a backpack, make sure that its width and length match each child’s torso. It shouldn’t hang more than 4 inches below the waist. The bottom of the pack should closely align with the curve of the child’s lower back — if it wobbles back and forth, spine problems can develop. Other features to look for include wide, padded and adjustable shoulder straps. A waist, hip and/or chest belt will more evenly distribute the load. A backpack with many compartments allows for its content to be well spaced throughout. For traffic safety, the pack should have reflective accents that will help cars and other vehicles see your child in low light conditions. Before loading the pack, have your child put it on and adjust the straps for a snug fit. Put the heaviest items at the back of the pack. Arrange the contents… read on >

School kids who get to bed early rather than staring at their devices at night may be better equipped to control their behavior, a new study suggests. Researchers found that 8- to 11-year-olds who got adequate sleep and had limits on “screen time” were less likely than their peers to report problems with impulsive behavior. Impulsivity is generally described as a tendency to act without thinking, or an inability to wait for something you want. It’s a central problem in attention-deficit/hyperactivity disorder (ADHD). Later in life, impulsivity may also make kids vulnerable to other problems, like substance abuse and other forms of addiction, said lead researcher Michelle Guerrero. Guerrero said her team wanted to see what factors might affect that tendency to “act before thinking.” In general, the researchers found, kids were less likely to report impulsive behavior if they met recommendations for sleep and screen time. That meant nine to 11 hours of sleep each night and no more than two hours a day devoted to “recreational” screen time. (School work didn’t count.) However, the findings only point to a correlation, said Guerrero, a fellow with the Children’s Hospital of Eastern Ontario Research Institute, in Ottawa, Canada. They do not prove earlier bed times and screen limits will actually prevent impulsivity, she explained. “Is it that impulsive kids don’t meet the recommendations, or that… read on >

(HealthDay News) — Aloe vera is a plant that has been widely used for its healing abilities, the U.S. National Center for Complementary and Integrative Health says. Topical aloe vera is likely to be safe and helpful for psoriasis and certain skin rashes, the center says. But the center warns against consuming the plant orally. Cramps and diarrhea have been reported as symptoms of ingested aloe. The center recommends telling your doctor about any “alternative” or “complementary” health approaches you use. This will give your doctor a full picture of how you manage your health, and help ensure safer care.

(HealthDay News) — The chills refers to an episode of shivering, along with paleness and feeling cold. Most commonly, the chills are associated with fever, says Mount Sinai Hospital. They are the body’s way of producing heat when it feels cold. To treat the chills at home, Mount Sinai recommends: Drink lots of fluids and get plenty of rest. Sponge with lukewarm water. Take acetaminophen to fight fever and chills. Don’t bundle up in blankets or use air conditioning. If you have a high fever or your chills are accompanied by stiffness of the neck, confusion, or pain, seek prompt medical attention.

For parents of a child with autism, communication is often the No. 1 hurdle. But what if there were a simple way to help them get their youngster talking? A new study suggests there just might be. It’s called “pivotal response treatment” (PRT). And those who have tried it say it can open up a whole new verbal world for kids with limited speech and inhibited social skills. “My son was having meltdowns all the time because he couldn’t express what he wanted or needed,” said Heidi Pim, a kindergarten teacher in Palo Alto, Calif., whose son James, 8, was diagnosed as a toddler with autism and speech delays. “We would try our best to figure out what he wanted or needed, so we could give it to him, but often we couldn’t,” she said. “Because he didn’t have any vocabulary. And his frustration and aggression would just turn into situations everywhere I would take him. At shopping malls, airports, everywhere.” James was already undergoing standard “applied behavioral analysis” (ABA) treatment. Considered the gold standard among autism interventions, it aims to teach social skills through heavy monitoring, repetition and positive reinforcement of good behavior, typically in a clinical setting. PRT has roots in ABA. But it aims to keep the child in his or her usual setting, and relies on techniques that are easy for… read on >

Want to reduce your risk of dementia? Take care of your heart. That’s the takeaway from a new study that suggests good heart health in middle age could lower your odds for problems with thinking and memory later in life. The study included nearly 7,900 British adults who did not have heart disease or dementia at age 50. Over an average 25-year followup, 347 cases of dementia were diagnosed among participants. Average age at diagnosis: 75. After taking other factors into account, researchers linked a higher score at age 50 on seven healthy habits outlined in the American Heart Association’s “Life Simple 7” with a lower risk of dementia later in life. The Life Simple 7 assesses smoking, diet, physical activity, fasting blood sugar, blood cholesterol, blood pressure and body mass index (a measure of body fat based on height and weight). Dementia rates were 1.3 per 1,000 person years among participants who had high scores on heart healthy habits, compared to 3.2 per 1,000 for low-scorers, according to the study published Aug. 7 in the BMJ. A better score at age 50 was also associated with higher overall brain and gray matter volumes in MRI scans 20 years later. Though the study could not prove that heart-healthy living actually caused dementia risk to drop, the researchers said their findings support public policies to improve… read on >

Family meals are a recipe for healthy eating in kids, nutritionists say. “Research shows that families who regularly dine together are more likely to eat more fruits, vegetables and fiber and are less likely to eat fried foods,” said Kristen Gradney, a dietitian nutritionist and spokeswoman for the Academy of Nutrition and Dietetics. “Eating together promotes healthy weight in children, perhaps due to more nourishing food choices, and can encourage them to try new foods,” she explained in an academy news release. Plus, families who eat together tend to be closer, because mealtime encourages conversations. It helps kids feel more at ease sharing their feelings, which, in turn, can help lessen behavioral problems and may even improve their grades, Gradney said. As part of Kids Eat Right Month in August, the academy offers this advice to help parents make and enjoy family meals after a busy day: Choose meals without a lot of ingredients. Work with your children to create a collection of go-to recipes that can be ready in less than 30 minutes. Stock up on ingredients that can be used for more than one meal. For example, grill twice as many chicken breasts as needed for one dinner and use the extras to make fajitas the next night. Try to avoid take-out food. Though convenient, it’s not as healthy as a simple, homemade… read on >
