Natural Hazard Mortality Map Update

LiveScience offers an interesting perspective on yesterday’s Risk of Death: Natural Hazard Mortality Map post.

In the article “US Death Map: Where and How Nature Kills Most”, Senior Writer Jeanna Bryner observes that “Overall, during the study period, nearly 20,000 people died due to natural hazards. For comparison, here are the top five causes of U.S. deaths in 2005, according to the Centers for Disease Control and Prevention:

Heart disease: 652,091 deaths
Cancer: 559,312
Stroke (cerebrovascular diseases): 143,579
Chronic lower respiratory diseases: 130,933
Accidents (unintentional injuries): 117,809”

Snooze, Don’t Lose

A recent study of a county-wide Kansas school district published in the latest edition of the Journal of Clinical Sleep Medicine concluded that a one-hour delay in the start time for classes led to significantly reduced traffic accidents involving middle and high school students, improved sleep time, and reduced daytime drowsiness.

As described in a press release from the American Academy of Sleep Medicine, “average crash rates for teen drivers in the study county in the two years after the change in school start time dropped 16.5 percent compared to the two years prior to the change, while teen crash rates for the rest of the state increased 7.8 percent over the same time period.”

For further information about the study, see this article in Science Daily. For an abstract of the study itself, “Adolescent Sleep, School Start Times, and Teen Motor Vehicle Crashes”, look here.
