Only 48% of school age children in the United States get 9 hours of sleep most weeknights, according to a new research being presented at the American Academy of Pediatrics ( AAP) 2019 National Conference & Exhibition in New Orleans. An abstract of the study, "Sounding the Alarm on the Importance of Sleep” , will be presented on Saturday, Oct. 26, at the Ernest N. Morial Convention Center in New Orleans.
“Long-term sleep loss is a serious public health problem among children,” said abstract author Hoi See Tsao, MD, FAAP. "Insufficient sleep among adolescent, for example, is associated with physical and mental health consequences including increased risk of depression and obesity and negative effects on mood, attention and academic performance.”
Dr. Tsao said, "Our research shows that children who get enough sleep are more likely to flourish(健康成长)in comparison to children with insufficient sleep."
Researchers analyzed responses from parents and caregivers of 49,050 children ranging in age from 6-17 years old in the combined 2016-2017 National Survey of Children's Health. They answered questions on how many hours of sleep a randomly selected child in their household slept on an average weeknight. For the study, sufficient sleep was defined as sleeping greater than or equal to 9 hours on an average weeknight.
The researchers found that sufficient sleep, was positively associated with several individual flourishing markers, as well as the combined childhood flourishing measure. The researchers also identified risk factors associated with insufficient sleep, which included lower levels of parental or caregiver education, the presence of mental health conditions and so on.
Dr. Tsao said the study strengthened the importance of increasing efforts to help children get the recommended amount of sleep for their age. “Interventions like these may help children demonstrate more measures of childhood flourishing, enhance their development and give them brighter futures, " she said.

Seven years without a cold?
More and more people saying they just don't get colds anymore. They are using a new device made of pure copper, which scientists say kills cold and viruses. Doug Cornell invented the device in 2012. “I haven't had a single cold since then,” People were skeptical but EPA and university studies demonstrate repeatedly that viruses and bacteria die almost instantly when touched by copper. That’s why ancient Greeks and Egyptians used copper to purify water and heal wounds. Scientists say the high conductance (传导性) of copper disrupts electrical balance in a microbe (微生物) cell and destroys the cell in seconds.
So some hospitals tried copper touch surfaces like taps and door handles. This cut the spread of MRSA and other illnesses by over half, and saved lives. Colds start after cold viruses get in your nose, so the vast body of research gave Cornell an idea. When he next felt a cold about to start, he fashioned a smooth sheet copper and rubbed it gently in his nose for 60 seconds. “It worked!” he exclaimed, “The cold never got going.”
He asked relatives and friends to try it. They said it worked too so he patented CopperZap and put it on the market. Now tens of thousands of people have tried it. Nearly 100% of feedback says the copper stops colds if used within 3 hours after the first sign. Pat McAllister, age 70, received one for Christians and called it “one of the best presents ever.” “This little jewel really works,” People have used it on cold sores and say it can completely prevent outbreaks. It kills germs picked up on fingers and hands to protect you and your family. Copper even kills deadly germs that have become resistant to antibiotics.

It was late, about 10:15 p.m, when Janice Esposito arrived at the New York train station and began the 20-minute drive home. She had traveled the route so many times that she almost drove on autopilot (自动驾驶):a left onto Station Road, then a left on Montauk Highway, and then-bang! Out of nowhere, a car T-boned Janice’s car, pushing her backward onto the railroad tracks.
As it happened, Pole DiPinto was gelling ready for bed. He'd just closed his book when he heard the loud crash not far outside his bedroom window. A volunteer firefighter and retired teacher, 64, never stopped to think, He grabbed a flashlight and still in his pajamas (睡衣), ran out the door. “Any firefighter would have? done what I did,” he said, “We're always on duly.”
The first car he came upon was the one that had hit Janice. Once DiPinto concluded the driver was OK, he looked around and spotted Janice's car lay across the railroad tracks. And then he heard a terrible sound: the bells signaling an on-coming train.
DiPinto rushed to Janice's cur and banged on the driver's side window. She just looked at him, her eyes unfocused. “I don't know where I am,” she said. She seemed unhurt. “Honey, you're on the railroad tracks,” DiPinto shouted, “We have to get you off right now!” He pulled hard on the door handle, but it didn't work. The heavy train, traveling at 65 miles per hour, was heading toward them. DiPinto ran to the passenger side and threw open the door. “Please, God, don't let her be trapped”, he thought. He pushed aside the airbags, grabbed Janice's arms, and pulled her toward him across the passenger seat until he could help her out and walk her to safety. Within six seconds, he estimated, the train crashed into the car.
“It was like a Hollywood movie,” DiPinto told reporters the next day. But this one had a difference. That night, the hero arrived in pajamas, not in a fire truck.
