NPR – Aim for at least 7 hours of sleep nightly to fend off a cold
The viruses that cause the common cold are always lurking. But consider this: Even if we touch a doorknob or keyboard that’s covered in cold germs from an infected person, we don’t always catch the cold.
“Sometimes when we’re exposed to viruses, we end up not getting sick,” says Aric Prather, a psychologist at the University of California, San Francisco, who studies how our behaviors can influence our health.
Our immune systems often fend off the viruses that cause colds. But, how well our bodies mount this defense can vary.

TIME – No, selfies aren’t causing a teen lice epidemic
One thing is for certain — we’re all taking more selfies than we ever have before. And while social science experts may debate what that says about us, doctors are more concerned about something else entirely: lice.
Lice, those tiny, barely visible parasites that can cling onto fur and hair, are more common in kids, who tend to have more head-to-head contact and share things like hats and helmets. But some doctors have been reporting — anecdotally — that they’re seeing more lice among teens. A few are, rather dubiously, are blaming selfies.

USA Today – For sugar lovers, FDA’s proposed guidelines are not so sweet
America, we have a sugar problem. That’s a message we’ve been hearing from health authorities for years.
But lately, the message has gotten a lot more specific and comes down to this: If you are getting more than 10% of your calories from “added sugars” — everything from the sugar in your coffee to the high-fructose corn syrup in your ketchup —  you are getting too much. Some experts say even 10% is probably excessive, given the links between sugar and obesity, diabetes and heart disease.
The latest authority to endorse the 10% or less idea: the Food and Drug Administration. Under a proposal it announced this summer, food labels would have to say how close each serving comes to providing 50 grams, or 200 calories, of added sugar — the 10% mark for a typical 2,000-calorie diet.

Quartz – Murder rates are rising across America—but nobody knows why
The long decline of murders in American cities has started to take a deadly upward turn. Major cities across the country are seeing the number of homicides rise from last year’s figures.
The rise was covered last month by USA Today, and recent reporting by the New York Times revealed more data behind the trend. The Times analyzed homicide figures for various large cities that have seen more murders so far this year than at the same point in 2014.

CBS News – “Healthy Happy Meals” bill targets childhood obesity
Every parent knows the appeal fast food meals hold for kids, especially when there’s a toy included in the deal.
To help make those temptations a little less unhealthy, the New York city council member has proposed a “Healthy Happy Meals” bill, based on a similar ordinance in California.
Under the bill, restaurants serving special kids’ meals that come with a toy would be required to limit the total calories in the meal and the amount of fat, sugar and sodium. They would also have to add more nutrition through fruit, vegetables or whole grains.
