App to Prevent Breast Cancer?


While much of the nation supports breast cancer awareness in October with a show of pink, I encourage you also to reduce your cancer risk by lessening the blues in your life.

Significant studies have shown blue-rich light at night suppresses the body's ability to produce melatonin,* and melatonin itself suppresses the development of breast cancer.** Bright white light--a spectrum of all colors including blue--is the body's nighttime enemy.

The f.lux app reduces light that influences your body's circadian system by decreasing the blue light ouput of your electronic devices when your body is most vulnerable. If you're serious about preventing cancer, don't just wear pink and fundraise--get the free f.lux app and use it!

While you're at it, please reduce excessive (often unnecessary) outdoor lighting so your light pollution doesn't impair the well-being of others.

References excerpted from my Dark Skies page:

...The first is Seeing Blue,* a summary by the International Dark-Sky Association (IDA) that notes how blue-rich light coincides with the peak sensitive region of the human circadian system. The second is Breast cancer and circadian disruption from electric lighting in the modern world,** a paper by a team of physicians who have researched the impact of lighing on breast cancer in particular.

To lessen the blue light to which you are exposed through computers, cell phones, and other digital media, consider an app that automatically shifts the color output to "warmer" colors instead of the harsh blues. You can always override the app if you seek full color. From the IDA website:

  • F.lux is available for Mac OS/X, Windows, Linx, iPhones and iPads

  • Flux is available for Android devices (free or pay )

  • Twilight is available for smartphones or tablets
