«Breaking Pic News» Kids who sleep more get better grades, CDC says - as California considers later school start times

Children who don't get enough sleep perform worse in school, health officials have warned, as California considers delaying its school start times.

According to a new report from the US Centers for Disease Control and Prevention (CDC), students who sleep at least eight hours every night get better grades and have better attendance.

But more than 60 percent of middle schoolers and 70 percent of high schools don't get enough sleep every night, affecting their performance in school and leading to other physical and mental health issues - including depression and substance abuse.

Experts say that most teens are night owls and don't produce melatonin, the hormone that makes you drowsy, until much later at night but are forced to begin school around 8am each day. 

California Governor Jerry Brown has until the end of the month to decide if he will sign a bill into law that would ban the state's public middle and high schools from starting before 8.30am.

Health experts says the solution is not as simple as making sure children go to bed earlier. They explain that kids' brains function differently from those of adults.

'We have some evidence that most teenagers are night owls,' Dr Rebecca Robbins, a postdoctoral fellow and sleep researcher at the NYU Langone School of Medicine, told Daily Mail Online.

She explains this has to do with production of the hormone melatonin. 

Light is the main cue that influences our daily (circadian) rhythms. When the sun rises, the brain sends signals to the pineal gland to suppress melatonin production. 

When the sun sets, the pineal gland receives signals to secrete melatonin to make you drowsy.

'There is this phase shift where melatonin is not secreted in the brain until much later,' Dr Robbins said.

'Lots of teens find it hard to get to sleep until midnight or 1am. Unfortunately, because we live in a society that values being a morning person, we then make them get up really early for school.'

The CDC recommends a few tips to improve children's sleep, including making sure they go to bed at the same time each night, keeping their bedrooms cool and dimming the lights. 

However, there is a growing body of research that suggests delaying school start times can also help.

A 2016 review of 38 studies examined the association between school start times and sleep.

It found that delaying the start time by half an hour resulted in better attendance, less tardiness, fewer students falling asleep in class and improved grades. 

The CDC found that fewer than one in five US public middle schools and high schools began at the recommended start time of 8.30am during the 2011-12 school year.

The average start time was found to be 8.03am. 

'Schools that have a start time of 8.30am or later allow adolescent students the opportunity to get the recommended amount of sleep on school nights: about 8.5 to 9.5 hours,' researchers wrote.

'Insufficient sleep is common among high school students and is associated with several health risks such as being overweight, drinking alcohol, smoking tobacco, and using drugs - as well as poor academic performance.' 

A 2016 study from Brown University School of Public Health in Rhode Island confirmed this, finding that poor sleep health among middle schoolers was an indicator of alcohol and marijuana use later in adolescence.

Last week, California lawmakers passed a bill in both chambers, known as SB328, that would ban middle schools and high schools in the state from starting before 8.30am.

According to CDC data, almost 79 percent of public middle and high schools in the Golden State start before this time.

Governor Jerry Brown has until the end of the month to decide if he will sign the bill into law.

If he does, schools will have three years to comply with the law.

'This is the single most cost-effective thing we can do to improve high school graduation rates,' Assemblyman Jay Obernolte, R-Hesperia, told the Associated Press.

Opponents of the bill say it should be up to the local school boards, not the state, to put start times in place.

'When it comes to education, the farther away the decisions are made from the classroom, the worse those decisions are,' Assemblyman Jose Medina, D-Riverside, told the AP.

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.

Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
