New LED Light Bulb Mimics Sunset to Improve Sleep

Sunset

There’s a new LED light bulb in town. And it has been designed to help you fall asleep. Here’s the premise: Before we had electric lights, we adapted our sleep patterns to the rising and setting of the sun. But these days, many of us have completely lost touch with the natural rhythms of light and darkness. We stay up until the wee hours, our faces washed in the light of a computer or tablet screen, our eyes glazed over. We wake up to alarms, feeling perpetually like we haven’t gotten enough sleep. Sound familiar?

A couple months back, Medical News Today published an article on the effect of room lighting on decision making. Invoking crime dramas in which suspects are interrogated under bright lights, the report suggests that people tend to feel emotions more intensely in brighter light. This finding is significant not just for retailers but for anyone who consciously uses light in their spaces for a desired effect.

LEDs Transmit Data

A recent TedTalk about LED lights has garnered about a million and a half views. That high number isn’t surprising, given that LEDs have been making headlines a lot, lately. Tons of informational articles about the efficiency of LED light bulbs and how to choose them have been circulating online. But this TedTalk is about something quite different – data transmission.

The talk was given by Harold Haas, Chair of Mobile Communications at the University of Edinburgh, who coined the term LiFi, or light fidelity, to refer to a visible light communications (VLC) system. LiFi uses LEDs, which, of course, are electronic semi-conductors, as a medium to deliver networked, mobile, high-speed communication.

Where Did the Phrase “Go Green” Come From?

Go Green?

“Going green” has come to symbolize environmentalism in such a familiar way that most of us don’t think twice about who first coined the phrase.

I was curious about the origin of the term and wondered what made it take such strong hold in the English language. Speaking of curiosities, remember Heinz’s food flop several years ago when they decided to go green (literally) with ketchup? Glad that didn’t take hold.

Most people associate the beginning of the green movement and environmentalism with the publication of Silent Spring by Rachel Carson in the 1970’s.

Surprisingly, it dates back even further, to Henry David Thoreau’s writings in the 19th century. Thoreau spoke about living a “green” life in The Maine Woods in his call for conservation, forest preservation and respect for nature. You are probably familiar with several of Thoreau’s famous inspirational quotes (i.e., “Go confidently in the direction of your dreams,” or “What lies behind us and what lies ahead of us are tiny matters compared to what lies within us”). His greener remarks include:

What is the use of a house if you don’t have a decent planet to put it on?

This one’s my favorite (Thoreau, you were a funny guy!):

Beware of all enterprises that require a new set of clothes.

Did you have any idea the U.S. “green movement” was rooted in early American philosophy?
