19-32 Segment 1: The Economics of Later School Start Times

The Economics of Later School Start Times

Thirty years of research have shown that teenagers’ biology prevents them from getting to sleep much before 11pm, and with most high schools starting classes around 8 am, they are chronically sleep deprived. Experts discuss how students and even the economy would benefit from later start times and the reasons many people and school districts still oppose the change.

TBI’s, Personality Change, and Marriage

Traumatic brain injury can profoundly change the injured in personality and temperament, as well as physically and cognitively. Spouses bear the brunt of these changes to the point many feel like they’re living with a stranger. Two experts and the spouse of a TBI victim discuss the many ways life changes after an injury and what can help to get them through the ordeal.

School Crossing Safety

With the school year approaching, drivers need to be aware of children in crosswalks—and away from them. However, increasing distractions for both pedestrians and drivers sometimes make that difficult. A safety expert and a veteran school crossing guard—the nation’s “favorite crossing guard”-- discuss.

Not Enough Sleep: Even Worse For You Than We Thought

Getting less than six hours of sleep per night has long been known to be hazardous to health, but the discovery of the mechanisms behind those hazards is leading scientists to strengthen their warnings. Too little sleep or poor sleep carries heart and brain risks that are powerful, as experts explain.

A Radical Diet to Prevent Heart Disease

Heart disease is the number one killer in the US, but a well known cardiologist says if everyone would follow a plant-based, oil-free diet, heart disease could be eradicated. Yet many cardiologists won’t prescribe such a diet, fearing it’s so difficult to follow that it’s a prescription for defeat. Experts discuss.

The Pros and Cons of Mobile Health Apps

Mobile health apps are becoming very popular, though some are being shown to have little benefit. Few barriers exist to almost anyone entering the field whether they have health expertise or not. Privacy is also a concern. Experts discuss how people can protect themselves and find apps that do what they want.

Obesity and Cancer Risk

Studies are finding that obesity significantly increases a person’s risk for a variety of cancers. However, not all forms of fat carry equal risk. An expert discusses who is more at risk and why.

Fatty Liver Disease: Silently Growing

Most people associate cirrhosis of the liver with heavy alcohol use. But nonalcoholic fatty liver disease, which also leads to cirrhosis, is growing rapidly, and may affect a quarter of the population. Experts discuss this silent disease and what people can do to prevent and treat it.

Cancer Treatment and Sex

Cancer treatment has always focused on survival. Now doctors are increasingly focusing on side effects, including the effect of treatment on sexual function and satisfaction. However, many patients are shy about bringing up their difficulties, unaware there are ways to help. One of the nation’s top experts discusses.

Genetic and Genomic Testing

When most of us think of genetic testing for health, we imagine tests to detect whether we’ve inherited genes that predispose us for cancer or other serious disease. But another kind of gene testing—genomic testing of tumor cells for their susceptibility to targeted treatments—is giving thousands of people hope of survival they’ve never had before. Experts discuss both genetic and genomic testing.
