The twice-a-year shift between Standard Time and Daylight Saving Time has serious effects on our health, safety and performance, at least for several days after the shift. But there’s also a benefit. As we prepare to “fall back” this Saturday night (or “spring forward” in March), let’s look at the effects and why we even have this time change in the first place. Here’s what I found.

Because some LED street lights harm humans and the environment, the AMA has adopted Community Guidance for their use.
CHICAGO – Strong arguments exist for overhauling the lighting systems on U.S. roadways with light emitting diodes (LED), but conversions to improper LED technology can have adverse consequences. In response, physicians at the Annual Meeting of the American Medical Association (AMA) today adopted guidance for communities on selecting among LED lighting options to reduce potential harmful human and environmental effects.
Converting conventional street lights to energy-efficient LED lighting leads to cost and energy savings, and a lower reliance on fossil-based fuels. Approximately 10 percent of existing U.S. street lighting has been converted to solid state LED technology, with efforts underway to accelerate this conversion.

This last Sunday, I watched “Sleepless in America,” a 2-hour documentary on the National Geographic channel, and I captured some of its powerful statistics and blended them with my own, forming the basis of today’s article. But first, here’s the 3-min trailer. Additional short video segments are included below, along with a related infographic, and if the full length video gets posted, I’ll include it too.

How much sleep do we Need?
Prepare for the Time Change
that comes after Halloween
The biannual shift between Standard Time and Daylight Savings Time is like a society-imposed jet lag that can throw off your body clock and disrupt your sleep patterns. In the Spring we set our clocks forward overnight and thus lose an hour of sleep, and in the Fall we have the opportunity to gain an hour of sleep.

Summer vacation is about to end, and the new school year is upon us, so I urge everyone with children or grandchildren to read and share this article. As I modeled in The Economic Value of Sleep, that can be worth millions of dollars in lifelong earnings and healthcare savings. It can also be a lifesaver, literally.
The research is in, and studies show that sleep duration and quality has a profound impact on health, safety and performance; but well over half of adults don’t sleep well enough, and a third sleep less than 6 hours/night when 7-9 is recommended. It’s much worse with adolescents since 70-90% don’t get enough sleep. The problem is now so bad that the CDC called insufficient sleep “a public health epidemic.”
UPDATE: The CDC just issued a press release saying, “Most US middle and high schools start the school day too early,” and suggested that later start times are important if students are to get enough sleep.
Sleep deprivation has become a terrifying problem in our on-the-go society, where working more and sleeping less can be seen as a badge of honor. But even nodding off momentarily can have disastrous results, as we saw in graphic news reports of the December Bronx Metro-North train derailment.
